Description

  The present invention relates to a simulated experience device for simulating the operation of a device for administering a liquid.

  Conventionally, a prefilled syringe filled with a liquid in advance is known. A prefilled syringe normally contains a liquid and is slidable in a syringe outer cylinder in which a discharge port for discharging the liquid is formed at the tip, a needle tube provided in the discharge port of the syringe outer cylinder, and the syringe outer cylinder And a pusher for pressing the gasket in the distal direction.

  By the way, a prefilled syringe is also used when a patient self-administers at home. However, the operation may be difficult when elderly people and women with weak power, patients with rheumatism with pain and deformation of fingers, and the like self-administer.

  Thus, for example, Patent Document 1 describes a drug delivery device in which a syringe outer tube and a needle tube are maintained inside a structure by a biasing force of a spring. When using this drug delivery device, the structure is pressed against the living body and the structure is pressed with the palm of the hand. As a result, the needle tube protrudes from the structure and is punctured into the living body, the pusher moves in the distal direction, and the drug is administered into the living body through the needle tube. Thereafter, by releasing the pressure on the structure, the needle tube is accommodated in the structure again by the biasing force of the spring.

  However, the drug delivery device described in Patent Document 1 is provided with a mechanism for preventing the needle tube from protruding again from the structure after use and preventing reuse, for safety. For this reason, the drug delivery device cannot be used repeatedly even when it is used in a pseudo manner as a training or promotion of the administration operation, that is, even when the administration of the liquid to the living body is not actually performed. Then, if an expensive drug delivery device is used for training or promotion of administration operation, a waste of cost occurs.

On the outer peripheral surface of the cover cylinder portion 31, two guide ribs 33 extending in the axial direction, two separation preventing projections 34, and two positioning ribs 35 are formed. The two guide ribs 33 project from positions facing each other across the central axis of the cover member 30 and are accommodated in the pressing portion first groove 25 of the operation member 20. Thereby, the cover member 30 can move relatively only in the axial direction without rotating relative to the operation member 20.

  The two protrusions 34 for preventing separation are provided to protrude radially outward at positions facing each other across the central axis of the cover member 30, and are accommodated in the pressing portion second groove 26 of the operation member 20. When the operating member 20 and the cover member 30 are relatively separated from each other in the axial direction, the separation preventing convex portion 34 is configured so that the separation preventing convex portion 34 is a base of the pressing portion second groove 26 (see FIG. 3). The operation member 20 is prevented from being completely detached from the cover member 30 by being caught at the end.

  The two positioning ribs 35 are provided to protrude radially outward at positions facing each other across the central axis of the cover member 30. The two positioning ribs 35 are formed away from the guide rib 33 on the extension line on the tip side of the two guide ribs 33. The positioning rib 35 can be accommodated in a positioning groove 65 (see FIG. 6) of the cap 60, which will be described later, whereby the mounting position of the cap 60 with respect to the cover member 30 can be positioned with high accuracy.

  Two safety convex portions 36 and two guide convex portions 37 are formed on the inner peripheral surface of the cover cylinder portion 31. The two safety protrusions 36 are provided so as to protrude radially inward at positions facing each other across the central axis of the cover member 30 and are accommodated in a safety groove 46 (see FIG. 5) of the rotating structure 40 described later. Is done. Each of the safety convex portions 36 is sandwiched between slits 361 that are formed in the cover tube portion 31 by being cut from the proximal end side and extending in the distal end direction. Therefore, the safety convex portions 36 are movable so as to bend radially outward. .

  The two guiding projections 37 are provided to project radially inward at positions facing each other across the central axis of the cover member 30 and are accommodated in a cam groove 45 of the rotating structure 40 described later. Each guide convex portion 37 is sandwiched between slits 371 formed by cutting from the base end side to the cover tube portion 31 and extending in the distal end direction, and is thus movable so as to bend radially outward. .

  A rotating structure holding portion 63 and a release pressing portion 64 (see FIG. 6) of the cap 60, which will be described later, can pass from the distal end side of the cover distal end portion 32 of the cover member 30 on the central axis of the cover member 30. An opening 38 is formed. In the actual liquid administration device, the opening 38 plays a role of allowing a needle tube provided in the rotating structure to pass in the distal direction.

  As shown in FIGS. 1, 2, and 5, the rotary structure 40 is provided inside the operation member 20 and the cover member 30 so as to be rotatable about a central axis. The rotary structure 40 includes an inner cylinder part 41 formed so as to be able to receive the pusher 22 from the base end side, an outer cylinder part 42 formed concentrically outside the inner cylinder part 41, an inner cylinder part 41, and A disc-shaped flat plate portion 43 connected to the tip portion of the outer cylinder portion 42 and a cylindrical tip tube portion 44 extending from the flat plate portion 43 in the tip direction are provided.

  Two cam grooves 45 and two safety grooves 46 are formed on the outer peripheral surface of the outer cylindrical portion 42.

  The two cam grooves 45 are formed at positions facing each other with the central axis of the rotating structure 40 interposed therebetween, and accommodate the guide convex portion 37 (see FIG. 4) of the cover member 30. Move relatively along. That is, the cam groove 45 and the guide convex portion 37 function as a cam mechanism (operation guide mechanism) that regulates the relative operation of the rotating structure 40 and the cover member 30.

  The cam groove 45 extends in the axial direction of the outer cylinder portion 42, and is formed so as to be inclined with respect to the initial linear groove 45 </ b> A (first groove portion) formed linearly and the axial direction of the outer cylinder portion 42. The inclined groove 45B (second groove portion), the linear groove 45C (third groove portion) that extends in the axial direction of the outer cylindrical portion 42, and is formed in the axial direction of the outer cylindrical portion 42. And an orthogonal groove 45D (fourth groove portion) formed so as to be orthogonal to each other.

  The initial straight groove 45 </ b> A extends from the distal end surface of the flat plate portion 43 in the proximal direction. At the tip of the initial linear groove 45A, a stepped portion 48 for receiving the guiding convex portion 37 in the initial linear groove 45A so as not to be detached when the device is assembled is formed. The stepped portion 48 is formed such that the tip side is inclined from the bottom surface of the initial linear groove 45A, and the guiding convex portion 37 can be guided along the inclined surface 48A while being guided to the initial linear groove 45A. Further, the stepped portion 48 is formed with a wall surface 48B whose base end side is cut at approximately 90 degrees from the bottom surface of the initial straight groove 45A, and once for the guiding through the inclined surface 48A beyond the stepped portion 48 to the base end side. The convex portion 37 is prevented from separating beyond the wall surface 48B of the stepped portion 48 again.

  The inclined groove 45B is formed so as to communicate with the proximal end portion of the initial linear groove 45A, and extends inclined from the proximal end portion of the initial linear groove 45A toward the proximal end. The inclined groove 45B is formed shorter than one round.

  The straight groove 45C is formed so as to communicate with the proximal end portion of the inclined groove 45B, and extends in the distal direction from the proximal end portion of the inclined groove 45B.

  The orthogonal groove 45D is formed to communicate with the distal end portion of the linear groove 45C, and reaches the initial linear groove 45A from the distal end portion of the linear groove 45C in a direction orthogonal to the central axis of the outer cylinder portion 42. It extends to.

  Note that the cam groove 45 may be formed in the cover member 30, and the guide convex portion 37 may be formed in the rotating structure 40.

  The tip tube portion 44 is formed concentrically with the inner tube portion 41 and the outer tube portion 42, and two release receiving portions 47 are formed so as to protrude from the inner peripheral surface. The release receiving portion 47 is provided at a position facing the central axis of the distal end cylindrical portion 44 and extends in the axial direction of the distal end cylindrical portion 44. The release receiving portion 47 can contact a release pressing portion 64 (see FIG. 6) of the cap 60 which will be described later, and receives a force for rotating the rotating structure 40 from the release pressing portion 64. is there.

  The two safety grooves 46 are formed at positions facing each other across the central axis of the rotating structure 40 and accommodate the safety convex portion 36 (second engagement portion) of the cover member 30. The safety groove 46 has a relative axial direction of the cover member 30 relative to the rotary structure 40 in accordance with the positional relationship between the rotary structure 40 and the cover member 30 that are relatively moved by the cam groove 45 and the guide convex portion 37. Regulate the movement of Therefore, the safety groove 46 and the safety convex portion 36 move the cover member 30 in the proximal direction with respect to the rotating structure 40, that is, perform an operation simulating puncture of a needle tube, and the cover member 30 has a rotating structure. After moving in the distal direction with respect to the body 40, a safety mechanism is configured to suppress the cover member 30 from moving again in the proximal direction with respect to the rotating structure 40. Note that the movement of the cover member 30 in the proximal direction with respect to the rotating structure 40 means that the needle tube protrudes from the cover member 30 in the liquid administration device, and the cover member 30 moves relative to the rotating structure 40. The movement in the distal direction means that the used needle tube is accommodated in the cover member 30 in the liquid administration device.

  The safety groove 46 extends in the axial direction of the outer cylinder portion 42 and is formed in a straight line, and the second safety groove 46A extends in parallel with the first safety groove 46A. The first safety groove 46A on the distal end side of the groove 46B, the proximal side communication groove 46C that communicates the proximal ends of the first safety groove 46A and the second safety groove 46B, and the proximal side communication groove 46C And a distal end side communication groove 46D for communicating the second safety groove 46B.

  The second safety groove 46B is formed with a safety step portion 49 (first engagement portion) that allows the safety convex portion 36 to move in the distal direction but suppresses the movement in the proximal direction. ing. The safety stepped portion 49 has a base-side safety inclined surface 49A inclined from the bottom surface of the second safety groove 46B, and the safety convex portion 36 is slid along the safety inclined surface 49A. While leading to the tip side. Further, the safety step portion 49 is formed with a safety wall surface 49B that is cut at approximately 90 degrees from the bottom surface of the second safety groove 46B on the distal end side, and once through the safety inclined surface 49A, the safety step portion 49 is formed. The safety convex portion 36 that extends beyond the distal direction engages with the safety stepped portion 49 and prevents the safety stepped portion 49 from crossing again in the proximal direction. The distal end side communication groove 46D is formed along the safety wall surface 49B.

  The rotating structure 40 and the cover member 30 are different in the rotational direction positions of the safety step portion 49 and the safety projection portion 36 when the guidance projection portion 37 is positioned in the initial linear groove 45A in the motion guide mechanism. It becomes a state. In this first state, the safety convex portion 36 is located in the first safety groove 46A, and even if the rotary structure 40 and the cover member 30 move relatively in the axial direction, the safety step portion 49 and The safety convex portion 36 is not engaged. The rotating structure 40 and the cover member 30 are in the second state in which the rotational positions of the safety step portion 49 and the safety convex portion 36 coincide when the guiding convex portion 37 is positioned in the linear groove 45C. Become. In this second state, the safety convex portion 36 is located in the second safety groove 46B, and the rotational structure 40 and the cover member 30 move relatively in the axial direction, so that the safety step portion 49 and The safety convex portion 36 can be engaged.

  Note that the safety groove 46 may be formed in the cover member 30, and the safety convex portion 36 may be formed in the rotating structure 40.

  As shown in FIG. 2, the coil spring 50 is disposed inside the cover member 30, and has a distal end portion in contact with the proximal end surface of the cover distal end portion 32 and a proximal end portion in contact with the flat plate portion 43 of the rotating structure 40. Yes. The coil spring 50 is disposed in a contracted state in the axial direction, and thereby urges the cover member 30 toward the distal end direction with respect to the rotating structure 40.

  As shown in FIGS. 1, 2, and 6, the cap 60 has a cylindrical cap cylinder portion 61 that covers the cover member 30 and a planar shape that is formed so as to close the opening on the front end side of the cap cylinder portion 61. The cap tip 62 is provided. On the proximal end surface of the cap distal end portion 62, two rotating structure holding portions 63 extending in the proximal direction and two release pressing portions 64 extending in the proximal direction are formed.

  The two rotating structure holding parts 63 are positioned so as to face each other with the central axis of the cap 60 therebetween, and both extend in the proximal direction. Each rotating structure holding part 63 can come into contact with the rotating structure 40 at the base end. For this reason, by attaching the cap 60 to the cover member 30, the rotating structure 40 is restrained from moving in the distal direction with respect to the cover member 30, and simulates an operation of projecting the needle tube from the cover member 30. Can be suppressed.

  The two release pressing portions 64 are positioned so as to face each other with the central axis of the cap 60 therebetween, and both extend in the proximal direction. Each release pressing portion 64 has a base end formed with a length that can reach the inside of the distal end tubular portion 44 of the rotating structure 40, and is formed on the inner peripheral surface of the distal end tubular portion 44. It can be adjacent to the receiving portion 47 in the circumferential direction (see FIG. 2). Therefore, by rotating the cap 60 with the release pressing portion 64 adjacent to the release receiving portion 47 in the circumferential direction, the release pressing portion 64 transmits a rotational force to the release receiving portion 47. The rotating structure 40 can be rotated with respect to the cover member 30. That is, the release pressing portion 64 and the release receiving portion 47 rotate the cap 60 with respect to the cover member 30 to shift from the second state to the first state, so that the safety step portion 49 in the safety mechanism. And it functions as a release mechanism that releases the engaged state of the safety convex portion 36.

  Furthermore, two positioning groove portions 65 that can accommodate the positioning ribs 35 of the cover member 30 are formed in the cap cylinder portion 61. The two positioning grooves 65 are positioned so as to face each other with the central axis of the cap 60 interposed therebetween. Each positioning groove 65 is formed on the base end side with a width substantially the same as the width of the positioning rib 35 (see FIG. 4), and the base end side positioning groove 65A through which the positioning rib 35 can pass. The proximal end positioning groove 65A is formed on the distal end side so as to communicate with the proximal end positioning groove 65A, and has a distal end positioning groove 65B wider than the proximal end positioning groove 65A. When attaching the cap 60 to the cover member 30, first, the positioning rib 35 is accommodated in the proximal-side positioning groove 65A. At this time, since the width of the proximal end positioning groove 65A is approximately the same as the width of the positioning rib 35, the circumferential position of the cap 60 with respect to the cover member 30 is positioned with high accuracy. That is, the positioning rib 35 and the proximal end positioning groove 65A function as a positioning mechanism. When the cap 60 is pushed in the proximal direction, the positioning rib 35 completely passes through the proximal-side positioning groove 65A and reaches the distal-side positioning groove 65B. Since the front end side positioning groove 65B is formed with a width wider than the width of the positioning rib 35, the cap 60 can be rotated with respect to the cover member 30.

  Further, the cap cylinder portion 61 is formed with two deformation allowing portions 66 projecting toward the inner peripheral surface side so as to be elastically deformable. The deformation | transformation permission part 66 is comprised by forming the slit 67 penetrated from the outer peripheral surface of the cap cylinder part 61 to an inner peripheral surface so that a cantilever may be comprised. When the cap 60 is attached to the cover member 30, the deformation allowing portion 66 contacts the outer peripheral surface of the cover member 30 while deforming radially outward, and the cap 60 is connected to the cover member 30 with a frictional force that can be removed. . Further, the cover member 30 disposed inside can be gripped via the deformation permission portion 66 by pushing in the deformation permission portion 66.

  The constituent materials of the operation member 20, the cover member 30, the rotating structure 40, and the cap 60 are not particularly limited. For example, polyvinyl chloride, polyethylene, polypropylene, cyclic polyolefin, polystyrene, poly- (4-methylpentene-1) , Polyesters such as polyethylene terephthalate and polyethylene naphthalate, butadiene-styrene copolymers, and polyamides (for example, various resins such as nylon 6, nylon 6,6, nylon 6,10, nylon 12).

  The constituent material of the coil spring 50 is not specifically limited, For example, metal materials, such as stainless steel and copper, are mentioned.

  Next, a method for using the simulated experience device 10 according to the first embodiment will be described.

  First, as shown in FIG. 2, an unused pseudo-experience device 10 in an initial state is prepared. In this first state, the pseudo-experience device 10 is in a state in which the operation member 20 is moved in the distal direction with respect to the rotating structure 40, and the cover member 30 is moved by the coil spring 50 with respect to the rotating structure 40. It is biased toward the tip. A cap 60 is attached to the cover member 30, the opening 38 is covered with the cap 60, and the rotating structure holding portion 63 of the cap 60 comes into contact with the rotating structure 40, so that the cover member of the rotating structure 40 is covered. The movement to the front-end | tip direction with respect to 30 is suppressed.

  Next, the operating member 20 and the cap 60 are gripped, the cap 60 is moved from the operating member 20 in the distal direction, and the cap 60 is removed from the operating member 20 and the cover member 30 as shown in FIG. At this time, as shown in FIG. 7A, in the operation guiding mechanism, the guiding convex portion 37 of the cover member 30 is located in the initial linear groove 45A of the rotating structure 40, and the initial linear groove 45A It can move along the axial direction of the rotating structure 40 along the axis. As shown in FIG. 7B, in the safety mechanism, the safety convex portion 36 of the cover member 30 is located in the first safety groove 46A of the rotating structure 40, and the first safety groove It can move in the axial direction of the rotating structure 40 along 46A. For this reason, the cover member 30 is in a state capable of moving in the proximal direction with respect to the rotating structure 40. The cover member 30 and the rotating structure 40 are in the first state in which the rotational position of the safety convex portion 36 and the safety step portion 49 are different.

  Next, the operation member 20 is grasped and the cover tip portion 32 of the cover member 30 is brought into contact with the living body. In addition, since the pseudo-experience device 10 is used for training and promotion, the target may not be a living body.

  When the cover distal end portion 32 of the cover member 30 is pressed against the object, the cover member 30 is movable in the proximal direction with respect to the rotating structure 40. Therefore, the cover member is contracted while the coil spring 50 is contracted. As shown in FIG. 8, 30 moves in the proximal direction with respect to the rotating structure 40. At this time, the frictional force generated between the rotating structure 40 and the operation member 20 is larger than the expansion force of the coil spring 50 so that the rotating structure 40 does not move in the proximal direction with respect to the operation member 20. Larger is preferred.

  When the cover member 30 moves in the proximal direction with respect to the rotating structure 40, as shown in FIG. 8A, in the operation guiding mechanism, the guiding convex portion 37 of the cover member 30 is rotated by the rotating structure 40. Of the initial straight groove 45A, that is, the tip end side of the inclined groove 45B. Further, as shown in FIG. 8B, in the safety mechanism, the safety convex portion 36 of the cover member 30 is located at the base end portion of the first safety groove 46A of the rotating structure 40, and It can move to the end side communication groove 46C. This state means a state where the needle tube protrudes from the cover member 30 in the distal direction and is punctured into the living body in the liquid administration device.

  Next, when the operation member 20 is further pressed, as shown in FIG. 9A, the guide convex portion 37 that reaches the inclined groove 45B presses the inclined groove 45B, and the guide convex portion 37 is inclined. The rotating structure 40 rotates until the inclination of the groove 45B reaches the base end of the sliding inclined groove 45B (the base end of the linear groove 45C). As shown in FIG. 9B, in the safety mechanism, when the rotating structure 40 rotates, the safety convex portion 36 passes through the base end side communication groove 46C, and the base end of the second safety groove 46B. Reach the department. At this time, the cover member 30 and the rotating structure 40 are in the second state in which the rotation direction positions of the safety convex portion 36 and the safety step portion 49 coincide.

  Next, when the operation member 20 is further pressed, the safety convex portion 36 of the cover member 30 cannot move further in the proximal direction in the cam groove 45, so that the cover member 30 is further moved against the rotating structure 40. Cannot move in the proximal direction. For this reason, as shown in FIG. 10, the operation member 20 moves in the distal direction with respect to the rotating body structure and the cover member 30. At this time, as shown in FIG. 10A, in the operation guiding mechanism, the cover member 30 does not move with respect to the rotating structure 40, so the guiding convex portion 37 does not move, and the base end of the inclined groove 45B. (Located at the base end of the linear groove 45C). As shown in FIG. 10B, even in the safety mechanism, the safety convex portion 36 does not move and is positioned at the base end portion of the second safety groove 46B. In addition, this state means the state which administered the liquid from the needle tube in the living body in the liquid administration device.

  Next, when the operating member 20 is gripped and the cover front end portion 32 is separated from the object, the cover member 30 moves toward the front end with respect to the rotating structure 40 by the biasing force of the coil spring 50 as shown in FIG. Moving. This state means a state in which the needle tube is accommodated in the cover member 30 in the liquid administration device. At this time, as shown in FIG. 11A, in the operation guiding mechanism, the guiding convex portion 37 moves to the tip portion of the linear groove 45C. When the guide convex portion 37 abuts against the distal end portion of the linear groove 45C, the cover member 30 cannot move in the distal end direction with respect to the rotating structure 40 any more. Further, as shown in FIG. 11B, in the safety mechanism, the safety convex portion 36 moves the second safety groove 46B in the distal direction, and the safety stepped surface 49A of the safety step portion 49 is moved. It slips and deforms to get over and reaches the front end side of the safety step 49. And once the safety convex part 36 gets over the safety level | step difference part 49, since the movement to the base end direction in the 2nd safety groove 46B of the safety convex part 36 is suppressed by the safety wall surface 49B, a cover member The movement of the 30 rotating structures 40 in the proximal direction becomes impossible and the safety mechanism is activated. This state means a state in which a safety mechanism that suppresses re-projection of the needle tube from the cover member is activated in the liquid administration device.

  Next, the cap 60 is gripped and moved in the proximal direction with respect to the cover member 30, and the cap 60 is mounted so as to cover the opening 38 of the cover member 30 as shown in FIGS. . At this time, the positioning rib 35 provided on the outer peripheral surface of the cover member 30 is mounted so as to be accommodated in the proximal-side positioning groove portion 65A of the cap 60, so that the cap is positioned at a predetermined circumferential position with respect to the cover member 30. 60 can be installed. Accordingly, as shown in FIGS. 13 and 14, the proximal end portions of the two release pressing portions 64 of the cap 60 reach the inner side of the distal end cylindrical portion 44 of the rotating structure 40, and the inner periphery of the distal end cylindrical portion 44. Adjacent to the release receiving portion 47 formed on the surface in the circumferential direction.

  When the positioning rib 35 of the cover member 30 completely passes through the proximal-side positioning groove 65A and reaches the distal-side positioning groove 65B, the distal-side positioning groove 65B is positioned as shown in FIG. Since the width is larger than the width of the rib 35, the cap 60 can be rotated with respect to the cover member 30 and the operation member 20 that rotates integrally with the cover member 30.

  When the cap 60 is rotated with respect to the cover member 30 and the operation member 20, the release pressing portion 64 presses the release receiving portion 47 formed on the rotary structure 40, and as shown in FIG. The body 40 rotates inside the cover member 30 and the operation member 20. At this time, as shown in FIG. 16A, in the motion guiding mechanism, the guiding convex portion 37 moves in the orthogonal groove 45D and reaches the initial linear groove 45A. Further, as shown in FIG. 16B, in the safety mechanism, the safety convex portion 36 moves in the tip side communication groove 46D and reaches the first safety groove 46A. As a result, the cover member 30 and the rotating structure 40 return to the first state, the restriction of the safety convex portion 36 by the safety stepped portion 49 is released, that is, the safety mechanism is released, and the rotating structure of the cover member 30 is released. The movement toward the proximal direction with respect to the body 40 becomes possible again.

  Next, as shown in FIG. 17, the deformation allowing portion 66 of the cap 60 is pressed and gripped so as to sandwich the cover member 30 via the deformation allowing portion 66. When the cap 60 is moved in the distal direction with respect to the operating member 20 in this state, as shown in FIG. 17A, in the operation guiding mechanism, the guiding convex portion 37 is formed on the stepped portion 48 of the initial linear groove 45A. The initial linear groove 45 </ b> A is moved until it comes into contact, and the cover member 30 moves in the distal direction with respect to the rotating structure 40. And since the convex part 37 for guidance cannot get over the level | step-difference part 48 of 45 A of initial stage straight grooves, the movement with respect to the rotation structure 40 of the cover member 30 beyond this becomes impossible, and it is an operation member 20 moves in the proximal direction. Thereafter, when the cap 60 is removed from the cover member 30 again, the state shown in FIG. 7 is obtained, and the simulated experience operation can be performed again.

  As described above, in the simulated experience device 10 according to the first embodiment, the rotating structure 40 and the cover member 30 are relatively rotated, so that the safety step portion 49 (first engaging portion) and the safety are secured. It is possible to be in a first state in which the rotational direction position of the convex portion 36 (second engaging portion) is different, and in a second state in which the rotational direction position is the same. By relatively rotating the rotating structure 40 and the cover member 30 from the state in which the stepped portion 49 and the safety convex portion 36 are engaged, it is possible to shift to the first state in which the experience operation can be performed again. For this reason, while being able to experience the liquid administration operation in a pseudo manner, the pseudo experience device 10 can be returned to the initial state again and the experience operation can be repeatedly performed. Moreover, since the simulated experience device 10 includes a safety mechanism and an operation induction mechanism included in an actual liquid administration device, it is possible to confirm an operation faithfully simulating the operation of the actual liquid administration device, such as training and promotion. Repeated experience operations can be performed while improving quality. And it becomes unnecessary to use an expensive liquid administration device for training, promotion, etc., and loss of cost can be suppressed. Moreover, since it is comprised without providing the needle tube provided in an actual liquid administration device, safety improves.

  The motion guide mechanism has a cam groove 45 in the rotating structure 40, and a guide convex portion 37 (convex portion) that is accommodated in the cam groove 45 and moves along the cam groove 45 in the cover member 30; The cam groove 45 communicates with the initial linear groove 45A (first groove portion) for relatively moving the rotating structure 40 and the cover member 30 in the axial direction in the first state, and the initial linear groove 45A. An inclined groove 45B (second groove portion) for relatively rotating the rotating structure 40 and the cover member 30 in order to shift from the state 1 to the second state, and the inclined groove 45B, and the second groove In this state, the rotary structure 40 and the cover member 30 are relatively moved in the axial direction to engage the safety step portion 49 (first engagement portion) and the safety convex portion 36 (second engagement portion). A straight groove 45C (third groove portion) and an initial straight line 45A and the linear groove 45C communicate with each other, and in the second state, the safety stepped portion 49 and the safety convex portion 36 are shifted from the engaged state to the first state. And an orthogonal groove 45D (fourth groove portion) for releasing the engagement of 36. For this reason, after the guiding convex portion 37 moves along the cam groove 45 and the pseudo-experience operation is finished from the first state to the second state, the guiding convex portion 37 is moved via the orthogonal groove 45D. It is possible to realize a structure that can be moved to the first state and that allows repeated experience operations.

  Further, in the second state, the safety step portion 49 (first engaging portion) and the safety convex portion 36 (second engaging portion) are shifted from the engaged state to the first state for safety. There is a release mechanism for rotating the rotating structure 40 relative to the cover member 30 by applying a rotational force to the rotating structure 40 so as to release the engagement between the stepped portion 49 and the safety convex portion 36. Therefore, the state where the safety stepped portion 49 and the safety convex portion 36 are engaged can be easily released by the release mechanism, and the operability is improved. Note that the release mechanism for releasing the state in which the safety step portion 49 (first engaging portion) and the safety convex portion 36 (second engaging portion) are engaged with each other is not necessarily provided. In this case, the state where the safety stepped portion 49 and the safety convex portion 36 are engaged can be released by rotating the rotating structure 40 using, for example, a general-purpose tool or the like or by the user's fingers.

  Further, since the release mechanism is provided on the cap 60 (protective member) that is detachably attached so as to cover the front end side of the cover member 30, the release operation can be performed using the cap 60 without providing a separate member. This makes it possible to improve operability.

The cap 60 (protective member) and the cover member 30 have a positioning structure that allows the cap 60 to be attached to the cover member 30 at a predetermined rotation angle. The cap 60 rotates with respect to the cover member 30 at a predetermined rotation. By mounting at an angle, the release receiving portion 47 that receives the rotational force of the rotating structure 40 has a release pressing portion 64 adjacent to the release receiving portion 47 so that the rotational force can be applied, and the cap 60 is relative to the cover member 30. Since the release operation by the release mechanism can be performed by rotating the cap 60, the release operation can be easily performed by simply rotating the cap 60, and the operability is improved.
Second Embodiment

  As shown in FIG. 18A, the simulated experience device 100 according to the second embodiment is the first only in that a second coil spring 110 (second biasing member) is provided inside the operation member 20. Different from the simulated experience device 10 according to the embodiment. In addition, about the site | part which has the function similar to the pseudo experience device 10 which concerns on 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The second coil spring 110 is disposed inside the operation member 20, the distal end portion is in contact with the proximal end surface of the outer cylinder portion 42 of the rotating structure 40, and the proximal end portion is the pressing proximal end portion 24 of the operation member 20. It touches the inner surface. The second coil spring 110 is disposed in a contracted state in the axial direction, and thereby urges the operation member 20 toward the proximal end direction with respect to the rotating structure 40. The expansion force (biasing force) of the second coil spring 110 is preferably larger than the axial frictional force between the operating member 20 and the rotating structure 40.

  The constituent material of the 2nd coil spring 110 is not specifically limited, For example, metal materials, such as stainless steel and copper, are mentioned.

According to the pseudo-experience device 100 according to the second embodiment, the second coil spring 110 (second biasing member) that applies force in a direction in which the operation member 20 and the rotary structure 40 are relatively separated is provided. After performing the pseudo experience operation by pressing the operation member 20 (see FIG. 10), the operation member 20 is rotated by using the expansion force of the second coil spring 110 as shown in FIG. It can be automatically moved in the proximal direction with respect to the body 40. For this reason, the operation | movement (refer FIG. 17) which hold | grips the cap 60 and the operation member 20, and moves the operation member 20 manually becomes unnecessary, and operativity improves.
<Third Embodiment>

  As illustrated in FIGS. 19 and 20, the simulated experience device 200 according to the third embodiment includes a needle tube 270 and can simulate a simulated liquid (liquid), and the operation member 220 moves relative to the rotating structure 240. It differs from 1st Embodiment and 2nd Embodiment by the point provided with the operation member fixing mechanism which regulates (operation | movement which administers a liquid) until a predetermined condition is satisfy | filled. In addition, the same code | symbol is attached | subjected to the site | part which has the same function as 1st Embodiment or 2nd Embodiment, and description is abbreviate | omitted.

  In the simulated experience device 200, a needle tube 270 protruding in the axial direction is fixed at the center of the flat plate portion 43 of the rotating structure 240. The needle tube 270 communicates with the internal space of the inner cylinder portion 41, and the inner cylinder portion 41 functions as a syringe that stores the simulated liquid. The rotating structure 240 includes two fixing beam portions 241 extending in the proximal direction from the proximal end side of the inner cylindrical portion 41.

  The two fixing beam portions 241 are provided at positions facing each other across the central axis of the rotating structure 240. Each of the fixing beam portions 241 is formed with a fixing convex portion 242 protruding toward the pusher 222 at the base end portion. The fixing convex portion 242 is accommodated in a fixing groove portion 227 of the pusher 222 described later. The fixing beam portion 241 can be bent outward in the radial direction so as to separate the fixing convex portion 242 from the pusher 222.

  As shown in FIGS. 19 and 20, a fixing groove portion 227 is formed on the outer surface of the pusher 222 formed on the operation member 220. The fixing groove portion 227 includes a pusher base end groove 227A formed all around in the circumferential direction, and a pusher tip end groove 227B formed all over the circumference in the front end side of the pusher base end groove 227A. And two pusher linear grooves 227C extending in the axial direction. The two pusher linear grooves 227C are provided at positions facing each other across the central axis of the pusher 222, and are axially extended from the distal end side of the pusher distal end groove 227B to the proximal end side of the pusher proximal end groove 227A. It is formed to extend. The pusher linear groove 227C communicates with the pusher distal end groove 227B and the pusher proximal end groove 227A. Between the pusher distal end groove 227B and the pusher proximal end groove 227A, a pusher inclined surface 227D having a diameter decreasing toward the proximal direction is formed, and the proximal end side of the pusher inclined surface 227D It is formed smoothly and continuously with the bottom surface of the base end groove 227A. Between the front end side of the pusher inclined surface 227D and the pusher front end groove 227B, a pusher stepped portion 228 that is cut at about 90 degrees from the pusher front end groove 227B is formed. The fixing convex portion 242 can move along the pusher straight groove 227C, the pusher proximal groove 227A, and the pusher distal groove 227B, and toward the pusher distal groove 227B from the pusher proximal groove 227A. In addition, it is possible to move on the pusher inclined surface 227D while bending the fixing beam portion 241. The fixing convex portion 242 cannot move on the pusher inclined surface 227D from the pusher distal end groove 227B toward the pusher proximal end groove 227A because the pusher stepped portion 228 is provided.

  The fixing convex portion 242 and the fixing groove portion 227 described above constitute an operation member fixing mechanism that restricts the movement of the operation member 220 relative to the rotating structure 240 (operation for administering the simulated liquid) until a predetermined condition is satisfied.

  A pusher convex portion 229 that protrudes in the distal direction is formed at the distal end portion of the pusher 222, and a gasket 280 is attached to the pusher convex portion 229. The gasket 280 can slide while maintaining liquid tightness with the inner wall surface of the inner cylinder portion 41.

  As shown in FIGS. 19 and 21, the cap 260 is formed with two container fixing protrusions 268 for fixing a simulation liquid container 290 to be described later, in addition to the cap 60 in the first embodiment. . The two container fixing protrusions 268 are provided at positions facing each other with the central axis of the cap 260 interposed therebetween, and the simulated liquid container 290 is fixed in a replaceable manner so as to be sandwiched between the two container fixing protrusions 268. .

  The simulated liquid container 290 is a bottomed cylindrical container for storing a simulated liquid (liquid) to be actually sucked by the needle tube 270, and the proximal end is sealed with a plug 291 that can puncture the needle tube 270. Has been. The simulated liquid container 290 can be replaced each time the simulated experience device 200 is used.

  As shown in FIG. 19, the second coil spring 210 is disposed inside the operation member 220, the distal end portion is in contact with the proximal end surface of the outer cylinder portion of the rotating structure 240, and the proximal end portion is pressed by the operation member 220. It is in contact with the distal end surface of the proximal end portion 24. The second coil spring 210 is a state in which the coil contracts in a natural state where no external force is applied, and in a state where the second coil spring 210 is forcibly extended, the distal end portion is connected to the outer cylindrical portion 42 of the rotating structure 240, and the proximal end portion Is connected to the pressing base end portion 24 of the operation member 220. Therefore, the second coil spring 210 generates a force for moving the operation member 220 in the distal direction with respect to the rotating structure 240 and functions as an assist when discharging the simulated liquid from the inner tube portion 41 via the needle tube 270. . In addition, it is preferable that the contraction force of the second coil spring 210 has such a magnitude that the liquid is not automatically administered by the contraction force of the second coil spring 210 when the user does not press the operation member 220 in the distal direction. .

  The constituent material of the gasket 280 and the plug 291 is preferably an elastic material, but is not particularly limited. For example, various rubber materials such as natural rubber, butyl rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, and silicone rubber. And various thermoplastic elastomers such as polyurethane, polyester, polyamide, olefin, and styrene, or a mixture thereof.

  The constituent material of the needle tube 270 is not particularly limited, and examples thereof include metal materials such as stainless steel, aluminum or aluminum alloy, titanium or titanium alloy.

  The constituent material of the 2nd coil spring 210 is not specifically limited, For example, metal materials, such as stainless steel and copper, are mentioned.

  Next, a method for using the simulated experience device 200 according to the third embodiment will be described.

  First, as shown in FIG. 19, an unused simulated initial experience device 200 is prepared. In this first state, the pseudo-experience device 200 is in a state in which the operation member 220 is moved in the distal direction with respect to the rotating structure 240, and the cover member 30 is moved by the coil spring 50 with respect to the rotating structure 240. The needle tube 270 is accommodated in the cover member 30 by being biased toward the distal end side. The opening 38 of the cover member 30 is covered with a cap 260, and the rotating structure holding portion 63 of the cap 260 is positioned in contact with or away from the rotating structure 240, so that the cover member of the rotating structure 240 is covered. The movement to the front-end | tip direction with respect to 30 is suppressed. As shown in FIG. 22 (A), in the motion guiding mechanism, the guiding convex portion 37 is located at the tip of the linear groove 45C, and as shown in FIG. 22 (B), in the safety mechanism, The safety convex portion 36 is located on the distal end side of the safety stepped portion 49. For this reason, the movement of the safety convex portion 36 in the proximal direction is suppressed by the safety wall surface 49B, and the movement of the cover member 30 in the proximal direction with respect to the rotating structure 240 is impossible. As shown in FIG. 22C, the fixing convex portion 242 is located at the intersection of the pusher base end groove 227A and the pusher linear groove 227C.

  Next, the operating member 220 and the cap 260 are gripped, the cap 260 is moved in the distal direction from the operating member 220, the cap 260 is removed from the operating member 220 and the cover member 30, and the cap 260 is removed as shown in FIG. The simulated liquid container 290 is attached to the container fixing protrusion 268. Thereafter, the cap 260 is attached to the cover member 30 again. As a result, as shown in FIG. 23, the needle tube 270 is pierced into the stopper 291 of the simulated liquid container 290 fixed to the cap 260.

  Next, when the operation member 220 and the cap 260 are gripped and the cap 260 is rotated with respect to the operation member 220, the base end portions of the two release pressing portions 64 (see FIG. 21) of the cap 260 are rotated. When the release receiving portion 47 of the structure 240 is pressed to rotate the rotating structure 240, as shown in FIG. 24A, in the motion guiding mechanism, the guiding convex portion 37 moves in the orthogonal groove 45D. The initial straight groove 45A is reached. Further, as shown in FIG. 24B, in the safety mechanism, the safety convex portion 36 moves in the tip side communication groove 46D and reaches the first safety groove 46A. Accordingly, the restriction of the safety convex portion 36 by the safety step portion 49 is released, and the cover member 30 can move in the proximal direction with respect to the rotating structure 240. As shown in FIG. 24C, in the operation member fixing mechanism, the fixing convex portion 242 moves in the pusher base end groove 227A and reaches the base end side of the pusher inclined surface 227D. As a result, the operation member 220 is movable in the proximal direction with respect to the rotating structure 240.

  Next, as shown in FIG. 25A, the deformation allowing portion 66 of the cap 260 is pressed and gripped so as to sandwich the cover member 30 via the deformation allowing portion 66. In this state, when the operation member 220 is moved in the proximal direction with respect to the cap 260, the movement guide mechanism moves the initial linear groove 45A until the guide convex portion 37 contacts the stepped portion 48 of the initial linear groove 45A. The cover member 30 moves in the distal direction with respect to the rotating structure 240. And since the convex part 37 for guidance cannot get over the level | step-difference part 48 of 45 A of initial linear grooves, the movement with respect to the rotation structure 40 of the cover member 30 beyond this becomes impossible, and with respect to the rotation structure 240 after this, The operating member 220 moves in the proximal direction. As a result, as shown in FIG. 26, the second coil spring 210 is stretched, the gasket 280 moves in the proximal direction within the inner cylinder portion 41, and the simulated liquid in the simulated liquid container 290 is transferred via the needle tube 270. Sucked into the inner cylinder portion 41. In the operation member fixing mechanism, as shown in FIG. 25C, the fixing convex portion 242 located in the pusher base end groove 227A moves on the pusher inclined surface 227D while bending the fixing beam portion 241. It moves and moves to the pusher tip groove 227B. When the fixing convex portion 242 is accommodated in the pusher distal end groove 227B, the fixing stepped portion 228 is provided on the proximal end side of the pusher distal end groove 227B, so that the fixing convex portion 242 becomes the pusher distal end groove 227B. Cannot move toward the pusher base end groove 227A. Thereby, the operation member 220 can be maintained at a position away from the rotary structure 240 while resisting the contraction force of the stretched second coil spring 210. Thereafter, the pressing of the cap 260 against the deformation allowing portion 66 is stopped, the cap 260 is removed from the cover member, and the preparation before the simulated experience operation is completed.

  Next, the operation member 220 is gripped and the cover tip portion 32 of the cover member 30 is brought into contact with the object. In addition, since the simulated experience device 200 actually administers the simulated liquid through the needle tube 270, the object needs to be capable of being pierced by the needle tube 270 and capable of being administered.

  When the cover distal end portion 32 of the cover member 30 is pressed against the object, the cover member 30 is movable in the proximal direction with respect to the rotating structure 240 as shown in FIG. 30 moves in the proximal direction with respect to the rotating structure 240 while contracting the coil spring 50, and the needle tube 270 protrudes through the opening 38 of the cover member 30 in the distal direction and pierces into the symmetrical object.

  When the cover member 30 moves in the proximal direction with respect to the rotating structure 240, as shown in FIG. 27A, in the operation guiding mechanism, the guiding convex portion 37 of the cover member 30 is rotated by the rotating structure 240. Of the initial straight groove 45A, that is, the tip end side of the inclined groove 45B. As shown in FIG. 27B, in the safety mechanism, the safety convex portion 36 of the cover member 30 is located at the base end portion of the first safety groove 46A of the rotating structure 240, and It can move to the end side communication groove 46C. In the operation member fixing mechanism, as shown in FIG. 27C, the fixing convex portion 242 is positioned on the distal end side of the pusher stepped portion 228 in the pusher distal end groove 227B. Movement in the distal direction with respect to the structure 240 is suppressed, and unintended discharge of the simulated liquid from the needle tube 270 can be suppressed.

  Next, when the operation member 220 is further pressed, as shown in FIG. 28A, the guiding convex portion 37 that has reached the inclined groove 45B presses the inclined groove 45B, and the guiding convex portion 37 is inclined. The rotating structure 240 rotates until the inclination of the groove 45B reaches the base end of the sliding inclined groove 45B (the base end of the linear groove 45C). As shown in FIG. 28 (B), in the safety mechanism, when the rotating structure 240 rotates, the safety convex portion 36 passes through the base end side communication groove 46C, and the base end of the second safety groove 46B. Reach the department. As shown in FIG. 28C, in the operating member fixing mechanism, the rotating convex body 242 reaches the pusher linear groove 227C by rotating the rotary structure 240, and the rotary structure of the pusher 222 is rotated. It will be in the state which can move to the tip direction to 240. That is, the operating member fixing mechanism is released.

  Next, when the operation member 220 is further pressed, the safety convex portion 36 of the cover member 30 cannot move further in the proximal direction in the cam groove 45, so that the cover member 30 does not move further against the rotating structure 240. Do not move in the proximal direction. Then, since the operation member fixing mechanism is released, the operation member 220 moves in the distal direction with respect to the rotating structure 240 and the cover member 30 as shown in FIG. 29, and the gasket 280 (see FIG. 26). However, the simulated liquid is administered from the needle tube 270 that has punctured the object. At this time, as shown in FIG. 29A, in the motion guiding mechanism, the cover member 30 does not move with respect to the rotating structure 240, so the guiding convex portion 37 does not move, and the base end of the inclined groove 45B. (Located at the base end of the linear groove 45C). As shown in FIG. 29B, even in the safety mechanism, the safety convex portion 36 does not move and is positioned at the base end portion of the second safety groove 46B. Then, as shown in FIG. 29C, in the operation member fixing mechanism, the fixing convex portion 242 moves in the proximal direction of the pusher linear groove 227C and reaches the pusher proximal end groove 227A.

  Next, when the operation member 220 is gripped and the cover front end portion 32 is separated from the object, the cover member 30 moves toward the front end with respect to the rotating structure 240 by the biasing force of the coil spring 50 as shown in FIG. The needle tube 270 is accommodated in the cover member 30. At this time, as shown in FIG. 30A, in the motion guiding mechanism, the guiding convex portion 37 moves to the tip portion of the linear groove 45C. When the guide convex portion 37 abuts against the front end portion of the linear groove 45C, the cover member 30 cannot move in the front end direction with respect to the rotating structure 240 any more. Further, as shown in FIG. 30B, in the safety mechanism, the safety convex portion 36 is deformed while moving the second safety groove 46B in the distal direction and sliding on the inclined surface of the safety step portion 49. Then, it gets over and reaches the front end side of the safety step 49. And once the safety convex part 36 gets over the safety level | step difference part 49, since the movement to the base end direction in the 2nd safety groove 46B of the safety convex part 36 is suppressed by the safety wall surface 49B, a cover member Thus, the movement of the 30 rotating structures 240 in the proximal direction becomes impossible and the safety mechanism is activated. As shown in FIG. 30C, in the operation member fixing mechanism, the fixing convex portion 242 does not move from the pusher base end groove 227A.

  Thereafter, the used simulation liquid container 290 fixed to the cap 260 is replaced with a new simulation liquid container 290, and the cap 260 is attached to the cover member. As shown in FIG. , The movement restriction of the cover member 30 in the proximal direction with respect to the rotating structure 240 by the safety mechanism is released, and the simulated experience operation can be performed repeatedly.

  As described above, according to the simulated experience device 200 according to the third embodiment, the second coil spring 210 (second biasing member) that applies a force in a direction in which the operation member 220 and the rotating structure 240 are relatively approached. Therefore, the second coil spring 210 generates a force for moving the operation member 220 in the distal direction with respect to the rotating structure 240, and fulfills a function of assisting the user's pressing operation (auxiliary function). For this reason, it is possible to perform an operation check faithfully simulating the operation of an actual liquid administration device having an auxiliary function, and it is possible to repeatedly perform the experience operation while improving the quality of training and promotion.

  Further, when the cover member 30 moves in the proximal direction relative to the rotating structure 240, a needle tube 270 (needle portion) that protrudes in the distal direction from the cover member is connected to the rotating structure 240. Therefore, the simulated experience operation of actually puncturing the object with the needle tube 270 and administering the simulated liquid can be performed repeatedly.

In addition, since the operation member fixing mechanism that restricts the movement of the operation member 220 in the distal direction with respect to the rotating structure 240 and can release the restriction by the relative rotation of the rotating structure 240 with respect to the operation member 220, the condition is satisfied. The simulated liquid is not discharged from the needle tube 270 until the erroneous puncture can be suppressed and the safety can be improved.
<Fourth embodiment>

  As shown in FIGS. 31 and 32, the pseudo experience device 300 according to the fourth embodiment is a coil spring to which the second coil spring 310 gives an expansion force, and a fixing groove portion of a pusher 322 that constitutes an operation member fixing mechanism. It is different from the third embodiment only in that the structure of 327 is different. In addition, the same code | symbol is attached | subjected to the site | part which has the same function as 1st-3rd embodiment, and description is abbreviate | omitted.

  In the simulated experience device 300, a fixing groove 327 is formed on the outer surface of the pusher 322 formed on the operation member 320. The fixing groove portion 327 includes a pusher base end groove 327A formed in the circumferential direction on the entire circumference, and a pusher distal end groove 327B formed in the circumferential direction on the distal side from the pusher base end groove 327A. And two first pusher inclined surfaces 327C extending in the axial direction and two second pusher inclined surfaces 327D extending in the axial direction. The two first pusher inclined surfaces 327 </ b> C are provided at positions facing each other across the central axis of the pusher 322. The two second pusher inclined surfaces 327D are provided at positions facing each other across the central axis of the pusher 322, and are alternately arranged in the circumferential direction with the first pusher inclined surface 327C. The first pusher inclined surface 327C is formed between the pusher distal end groove 327B and the pusher proximal end groove 327A with a diameter reduced toward the distal end, and the first pusher inclined surface 327C has a distal end side thereof. , And formed smoothly and continuously with the bottom surface of the pusher tip groove 327B. Between the base end side of the first pusher inclined surface 327C and the pusher base end groove 327A, a first pusher step portion 328 that is cut at about 90 degrees from the pusher base end groove 327A is formed. The second pusher inclined surface 327D is formed between the pusher distal end groove 327B and the pusher proximal end groove 327A so as to be reduced in diameter toward the proximal direction, and the proximal end of the second pusher inclined surface 327D. The side is smoothly and continuously formed with the bottom surface of the pusher tip groove 327B. Between the front end side of the second pusher inclined surface 327D and the pusher front end groove 327B, a second pusher stepped portion 329 that is cut from the pusher front end groove 327B at about 90 degrees is formed.

  The fixing convex portion 242 is movably accommodated in the pusher proximal groove 327A and the pusher distal groove 327B. Further, the fixing convex portion 242 is movable on the first pusher inclined surface 327C while bending the fixing beam portion 241 from the pusher distal end groove 327B toward the pusher proximal end groove 327A. It can move on the second pusher inclined surface 327D while bending the fixing beam portion 241 from the base end groove 327A toward the pusher distal end portion.

  The second coil spring 310 is disposed inside the operation member 320, the distal end portion is in contact with the proximal end surface of the outer cylinder portion 42 of the rotating structure 240, and the proximal end portion is the pressing proximal end portion 24 of the operation member 320. It touches the inner surface. The second coil spring 310 is disposed in a state of being contracted in the axial direction, thereby generating a force for moving the operation member 320 in the proximal direction with respect to the rotating structure 240, and supplying the simulated liquid via the needle tube 270. It plays a role of sucking into the inner cylinder portion 41.

  The constituent material of the 2nd coil spring 310 is not specifically limited, For example, metal materials, such as stainless steel and copper, are mentioned.

  Next, a method for using the simulated experience device 300 according to the fourth embodiment will be described.

  First, an unused initial simulated experience device 300 is prepared. In this state, in the pseudo-experience device 300, the operation member 320 is moved in the distal direction with respect to the rotating structure 240, and the cover member 30 is moved to the distal side by the coil spring 50 with respect to the rotating structure 240. The needle tube 270 is accommodated in the cover member 30 by being urged by. As shown in FIG. 33 (A), in the operation guiding mechanism, the guiding convex portion 37 is located at the tip of the linear groove 45C, and as shown in FIG. 33 (B), in the safety mechanism, The safety convex portion 36 is located on the distal end side of the safety stepped portion 49. For this reason, the movement of the safety convex portion 36 in the proximal direction is suppressed by the safety wall surface 49B, and the movement of the cover member 30 in the proximal direction with respect to the rotating structure 240 is impossible. As shown in FIG. 33C, in the operation member fixing mechanism, the fixing convex portion 242 is housed in the pusher base end groove 327A and is positioned on the base end side of the first pusher stepped portion 328. ing. Thereby, the operation member 320 is in a state incapable of moving in the proximal direction with respect to the rotating structure 240, and the second coil spring 310 is maintained in a contracted state.

  Next, the operation member 320 and the cap 260 are grasped, the cap 260 is moved from the operation member 320 in the distal direction, the cap 260 is removed from the operation member 320 and the cover member 30, and the container fixing protrusion 268 of the cap 260 is moved. A simulated liquid container 290 is attached. Thereafter, the cap 260 is attached to the cover member 30 again. As a result, as shown in FIG. 31, the needle tube 270 is pierced into the stopper 291 of the simulated liquid container 290 fixed to the cap 260.

  Next, when the operation member 320 and the cap 260 are gripped and the cap 260 is rotated with respect to the operation member 320, the proximal end portions of the two release pressing portions 64 (see FIG. 21) of the cap 260 are rotated. When the release receiving portion 47 of the structure 240 is pressed to rotate the rotating structure 240, as shown in FIG. 34A, in the motion guiding mechanism, the guiding convex portion 37 moves in the orthogonal groove 45D. The initial straight groove 45A is reached. As shown in FIG. 34 (B), in the safety mechanism, the safety convex portion 36 moves in the distal end side communication groove 46D and reaches the first safety groove 46A. Thereby, the restriction | limiting by the wall surface 49B for safety of the level | step difference part 49 for safety | security is cancelled | released, and the movement to the base end direction with respect to the rotating structure 240 of the cover member 30 will be possible. As shown in FIG. 34C, in the operation member fixing mechanism, the fixing convex portion 242 moves in the pusher base end groove 327A, and from the base end side of the first pusher stepped portion 328, It reaches the base end side of the two pusher inclined surface 327D. As a result, the operation member 320 becomes movable in the proximal direction with respect to the rotating structure 240, and the safety mechanism is released.

  When the fixing convex portion 242 reaches the proximal end side of the second pusher inclined surface 327D, the restraint of the second coil spring 310 is released, and the operation member 320 is moved to the second coil spring 310 as shown in FIGS. Due to the expansion force, the rotating structure 240 is automatically moved in the proximal direction. As a result, the gasket 280 moves in the proximal direction within the inner cylinder portion 41, and the simulation liquid in the simulation liquid container 290 is automatically sucked into the inner cylinder portion 41 via the needle tube 270. In the operation member fixing mechanism, as shown in FIG. 35C, the fixing convex portion 242 located in the pusher base end groove 327A deflects the fixing beam portion 241 while the second pusher inclined surface 327D. It moves up and moves to the pusher tip groove 327B. When the fixing convex portion 242 is housed in the pusher distal end groove 327B, the second pusher stepped portion 329 is provided on the proximal end side of the pusher distal end groove 327B, so that the fixing convex portion 242 It becomes impossible to move from the groove 327B toward the pusher base end groove 327A. Thereby, even if an unexpected force acts on the operation member 320, the operation member 320 can be maintained at a position away from the rotary structure 240, and unintended discharge of the pseudo liquid can be suppressed. Thereafter, the cap 260 is removed from the cover member 30 to complete the preparation before the simulated experience operation.

  Next, the operation member 320 is gripped and the cover tip portion 32 of the cover member 30 is brought into contact with the object. In addition, since the simulated experience device 300 actually administers the simulated liquid through the needle tube 270, the object needs to be capable of being pierced by the needle tube 270 and capable of being administered.

  When the cover distal end portion 32 of the cover member 30 is pressed against the object, the cover member 30 is released from the safety mechanism and is movable in the proximal direction with respect to the rotating structure 240. While contracting, the cover member 30 moves in the proximal direction with respect to the rotating structure 240 as shown in FIG. Thereby, the needle tube 270 passes through the opening 38 of the cover member 30, protrudes toward the distal end side, and is pierced into the symmetrical object.

  When the cover member 30 moves in the proximal direction with respect to the rotating structure 240, as shown in FIG. 37A, in the operation guiding mechanism, the guiding convex portion 37 of the cover member 30 is rotated by the rotating structure 240. Of the initial straight groove 45A, that is, the tip end side of the inclined groove 45B. As shown in FIG. 37B, in the safety mechanism, the safety convex portion 36 of the cover member 30 is located at the base end portion of the first safety groove 46A of the rotating structure 240, and It can move to the end side communication groove 46C. Further, in the operation member fixing mechanism, as shown in FIG. 37C, the fixing convex portion 242 is in contact with the second pusher stepped portion 329. The movement is suppressed and the simulated liquid is not discharged from the needle tube 270.

  Next, when the operation member 320 is further pressed, as shown in FIG. 38A, the guide convex portion 37 that has reached the inclined groove 45B presses the inclined groove 45B, and the guide convex portion 37 is inclined. The rotating structure 240 rotates until the inclination of the groove 45B reaches the base end of the sliding inclined groove 45B (the base end of the linear groove 45C). As shown in FIG. 38 (B), in the safety mechanism, when the rotary structure 240 rotates, the safety convex portion 36 passes through the base end side communication groove 46C, and the base end of the second safety groove 46B. Reach the department. As shown in FIG. 38 (C), in the operation member fixing mechanism, when the rotary structure 240 rotates, the safety convex portion 36 moves in the pusher tip groove 327B, and the first pusher inclined surface 327C. Reach the tip side. As a result, the pusher 322 can move in the distal direction relative to the rotating structure 240. That is, the operating member fixing mechanism is released.

  Next, when the operating member 320 is further pressed, the safety convex portion 36 of the cover member 30 cannot move further in the proximal direction in the cam groove 45, so that the cover member 30 does not move further against the rotating structure 240. Do not move in the proximal direction. Since the operation member fixing mechanism is released, as shown in FIG. 40, the operation member 320 moves in the distal direction with respect to the rotating structure 240 and the cover member 30, and the gasket 280 is disposed in the inner tube portion. Is moved in the distal direction, and the simulated solution is administered from the needle tube 270 punctured into the object. At this time, as shown in FIG. 39A, in the motion guiding mechanism, the cover member 30 does not move with respect to the rotating structure 240, so the guiding convex portion 37 does not move, and the base end of the inclined groove 45B. (Located at the base end of the linear groove 45C). As shown in FIG. 39B, also in the safety mechanism, the safety convex portion 36 does not move and is positioned at the base end portion of the second safety groove 46B. As shown in FIG. 39C, in the operating member fixing mechanism, the fixing convex portion 242 moves in the proximal direction on the first pusher inclined surface 327C and exceeds the first pusher step portion 328. To reach the pusher base end groove 327A.

  Next, when the operating member 320 is gripped and the cover front end portion 32 is separated from the object, the cover member 30 moves toward the front end with respect to the rotating structure 240 by the biasing force of the coil spring 50 as shown in FIG. The needle tube 270 is accommodated in the cover member 30. At this time, as shown in FIG. 40A, in the operation guiding mechanism, the guiding convex portion 37 moves to the tip portion of the linear groove 45C. When the guide convex portion 37 abuts against the front end portion of the linear groove 45C, the cover member 30 cannot move in the front end direction with respect to the rotating structure 240 any more. Further, as shown in FIG. 40B, in the safety mechanism, the safety convex portion 36 moves the second safety groove 46B in the distal direction, and the safety stepped surface 49A of the safety stepped portion 49 is moved. It slips and deforms to get over and reaches the front end side of the safety step 49. And once the safety convex part 36 gets over the safety level | step difference part 49, since the movement to the base end direction in the 2nd safety groove 46B of the safety convex part 36 is suppressed by the safety wall surface 49B, a cover member The movement of the 30 rotation structures 240 in the proximal direction becomes impossible. As shown in FIG. 40C, in the operation member fixing mechanism, the fixing convex portion 242 contacts the first pusher stepped portion 328 in the pusher proximal end groove 327A, and the operator moves to the operation member 320. The second coil spring 310 does not expand even if the pressing force is loosened, and the position of the operation member 320 is maintained.

  Thereafter, the used simulation liquid container 290 fixed to the cap 260 is replaced with a new simulation liquid container 290, and the cap 260 is attached to the cover member 30. As shown in FIG. By rotating with respect to 320, the movement limitation of the cover member 30 in the proximal direction relative to the rotating structure 240 by the safety mechanism can be released, and the simulated experience operation can be performed repeatedly.

  As described above, according to the simulated experience device 300 according to the fourth embodiment, the movement of the operation member 320 in the distal direction with respect to the rotation structure 240 is limited, and the relative rotation of the rotation structure 240 with respect to the operation member 320 is restricted. Therefore, the simulation liquid is not discharged from the needle tube 270 until the condition is satisfied, and the safety is improved.

  Further, the operation member fixing mechanism restricts the movement of the operation member 320 in the proximal direction with respect to the rotating structure 240 and can be released by the relative rotation of the rotation structure 240 with respect to the operation member 320. The operation member 320 can be restricted from moving in the proximal direction relative to the rotating structure 240 against the expansion force of the two-coil spring 310, and the operation member 320 can be automatically moved to the proximal end by releasing the restriction. The simulated liquid can be automatically sucked into the inner cylinder portion 41 from the needle tube 270, and the operability is improved.

  Note that the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art within the technical idea of the present invention. For example, in the third and fourth embodiments, the needle tube 270 is actually punctured into the target object and the simulated liquid is injected, but after the needle tube 270 is punctured into the target object, the simulated liquid is not injected. Also good. In this case, the needle part that pierces the object does not have to be a hollow needle tube. With such a configuration, the simulated liquid is not injected, but the operation of piercing the needle portion into the target object can be simulated.
