Description

  The present invention relates to a cage used for cleaning a medical instrument, and is particularly preferable when used for cleaning a tubular medical instrument.

  Generally, after a metal medical instrument is used for surgery or the like, it is cleaned and disinfected by a medical cleaning machine called a washer-disinfector and is used for the next use. In this case, the medical instrument is accommodated in a basket for each set, and the basket is loaded on a rack in the medical cleaning machine. The rack is provided with a plurality of stacking areas in the vertical direction, and baskets are stacked in each stacking area. During cleaning, cleaning liquid is sprayed from above and below each loading area into the basket.

  When a tubular medical instrument is cleaned by such a medical cleaning machine, it is difficult for the cleaning liquid to enter the tube of the medical instrument, which causes a problem that the inside of the medical instrument cannot be cleaned properly. In order to solve this problem, in the cleaning method described in Patent Document 1 below, after the connection tube is connected to the distal end of the tubular medical device, the medical device is immersed in the cleaning liquid. Negative pressure is applied by a vacuum pump or the like. Thereby, the cleaning liquid is guided to the inside of the medical instrument, and the inside of the medical instrument is cleaned.

  However, since the tip of the tubular medical instrument is covered with the connecting tube in the cleaning method described in Patent Document 1, the outer surface of the tip of the medical instrument is properly positioned even when the cleaning liquid is sprayed on the outer surface. It cannot be washed. For this reason, apart from the cleaning work by this cleaning method, it is necessary to clean the outer surface of the medical instrument by housing the medical instrument with the connection tube removed in the basket of the medical cleaning machine. As described above, it is very troublesome to perform the cleaning operation twice for one medical device.

  In view of such a problem, an object of the present invention is to provide a retainer for a medical instrument that can clean the outer surface of a tubular medical instrument and the inside of a tube smoothly by a simple operation.

  The retainer according to the present invention includes an insertion port provided at one end of the retainer and into which the medical instrument is inserted, and a connection portion to which a tube that is provided at the other end of the retainer and supplies a cleaning liquid is connected, An introduction path that guides the cleaning liquid supplied from the connection portion to the inside of the cage and injects the cleaning liquid from the other end side toward the one end side, and is provided on the one end side with respect to the introduction path A receiving portion that is inclined so as to gradually approach the central axis of the retainer from the one end side toward the other end side, and that receives a front end of the medical instrument inserted from the insertion port; and A support mechanism which is provided on the one end side and holds the medical instrument in a position along the central axis of the retainer by pressing the outer surface of the medical instrument at a plurality of points; the receiving part; and the support mechanism Said medical device supported by And a opening to open the outer surface to the outside.

  According to the present invention, a tube for supplying a cleaning liquid is further arranged in the basket-type medical cleaning machine, and the retainer holding the medical device is accommodated in the basket by connecting the tube to the connecting portion. Thus, the inner and outer surfaces of the tubular medical instrument can be smoothly cleaned only by this medical cleaning machine. That is, the inside of the medical instrument is cleaned by the flow of cleaning liquid sprayed from the introduction path. In addition, the outer surface of the medical device is cleaned by a cleaning liquid that enters the inside of the cage through the opening from above and below the basket or a cleaning liquid that is sprayed from the introduction path. At this time, since the front end of the medical instrument is received by the receiving portion inclined toward the central axis of the cage, it is not covered by the receiving portion. Therefore, the front end of the medical instrument is smoothly cleaned with the cleaning liquid. In addition, since the medical device is locked by the support mechanism by pressing the outer surface at a plurality of points, the outer surface is not substantially covered by the support mechanism. Therefore, the outer surface of the medical instrument is also smoothly cleaned by the cleaning liquid entering from the opening. Therefore, according to the present invention, the outer surface of the tubular medical instrument and the inside of the tube can be washed smoothly by a simple operation.

  In the cage according to the present invention, the receiving portion may be configured to include a conical inclined surface that is inclined so as to gradually approach the central axis of the cage as it goes from the one end side to the other end side. If it carries out like this, the front end of the medical device inserted from the insertion port will be guided to an inclined surface, and it will become easy to position the front end of a medical device to the central axis of a holder | retainer. For this reason, the cleaning liquid sprayed from the introduction path can be smoothly guided from the front end of the medical instrument to the inside.

  In this configuration, it is desirable that at least one protrusion extending along the generatrix of the inclined surface is provided on the inclined surface. If it carries out like this, the contact with a protrusion and the front end of a medical device will become a substantially point contact, and the front end of a medical device will be in the state which floated from the inclined surface. For this reason, the cleaning liquid easily flows from the opening to the front end of the medical instrument, and the front end of the medical instrument can be more reliably cleaned. Further, when the diameter of the medical instrument is large, a negative pressure is generated in the tube near the front end of the medical instrument due to the flow of the cleaning liquid flowing from the introduction path into the medical instrument. As a result, the cleaning liquid that has flowed from the opening flows into the tube from the outer surface of the front end of the medical instrument through the gap between the front end of the medical instrument and the inclined surface. By this flow, the inner surface near the front end of the medical instrument can be cleaned. Further, when the diameter of the medical device is small, the outer portion of the cleaning liquid sprayed from the introduction path leaks to the outer surface of the medical device through the gap between the front end of the medical device and the inclined surface. . As a result, the outer surface of the front end of the medical instrument is reliably washed with strong water pressure. Furthermore, since a part of the cleaning liquid leaks to the outer surface of the medical device in this way, the pressure applied to the inside of the medical device having a small diameter is reduced compared to the case where the cleaning liquid does not leak, and the cleaning liquid The force with which the medical instrument is pushed in the ejection direction is reduced. Thereby, even if it is the structure which hold | suppresses and supports a medical device by multiple points with a support mechanism, a medical device with a small diameter can be latched appropriately.

  In this configuration, it is desirable that three or more protrusions are provided on the inclined surface so as to surround the central axis of the cage. If it carries out like this, it will become easy to receive the front end of a medical device only by a protrusion, and the inner surface near the front end and front end of a medical device can be wash | cleaned more reliably.

  Furthermore, it is desirable that the protrusion has a cross-sectional shape whose width becomes narrower toward the top. If it carries out like this, the contact area of the front end of the medical device with respect to a protrusion can be made small, and the inner surface near the front end and front end of a medical device can be wash | cleaned still more reliably.

  In addition, when a receiving part is provided with an inclined surface as mentioned above, it can also be set as the structure by which an at least 1 groove | channel extended along the generatrix of an inclined surface is provided in an inclined surface. Also in this configuration, the flow of the cleaning liquid flowing from the introduction path into the medical instrument creates a negative pressure in the tube near the front end of the medical instrument, so that the cleaning liquid that has flowed from the opening passes through the groove and reaches the front end of the medical instrument. It flows into the pipe from the outer side. Therefore, when the diameter of the medical instrument is large due to this flow, the inner surface near the front end of the medical instrument can be effectively cleaned. In the case of a medical device having a small diameter, a part of the cleaning liquid sprayed from the introduction path leaks out of the groove to the outer surface of the medical device, so that the medical device is similar to the case where the protrusion is provided. The outer surface of the front end of the instrument can be reliably washed with strong water pressure, and the medical instrument can be properly locked.

  In this configuration, it is desirable that three or more grooves are provided on the inclined surface so as to surround the central axis of the cage. As a result, the inner side surface near the front end of the medical instrument is easily cleaned over the entire circumference. Moreover, in order to reduce the contact range of the medical device front end with respect to the inclined surface, it is desirable to make the width of the groove as wide as possible.

  In the cage according to the present invention, the receiving portion may have at least three frame portions that are inclined so as to gradually approach the central axis of the cage from the one end side toward the other end side. . In this case, the frame portion is disposed so as to surround the central axis of the cage. As a result, the front end of the medical instrument and its outer surface are exposed to the outside from the space between the frame parts, so that the cleaning liquid from the medical cleaner is introduced to the front end of the medical instrument and its outer surface compared to the inclined surface. It will be easier. Therefore, the front end of the medical instrument and its outer surface can be effectively cleaned.

  In the cage according to the present invention, the support mechanism may include a screw that can advance and retreat with respect to a central axis of the cage, and an end portion of the screw may have a diameter that decreases toward the tip. If it carries out like this, since the front-end | tip of a screw will carry out a substantially point contact with the outer surface of a medical device, the washing | cleaning residue will not arise in a contact location.

  In this configuration, it is preferable that at least three screws are arranged radially so as to surround the central axis of the cage. In this way, medical instruments having different diameters can be supported along the central axis by the support mechanism.

  As described above, according to the present invention, it is possible to provide a cage capable of smoothly washing the outer surface of a tubular medical device and the inside of a tube by a simple operation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. For convenience of explanation, the X axis, the Y axis, and the Z axis that are orthogonal to each other are appropriately appended to each drawing.

  FIGS. 1A to 1D are diagrams showing the configuration of the cage 1. 1A is a side view of the cage 1, and FIGS. 1B and 1C are a front view and a rear view of the cage 1, respectively. FIG.1 (d) is A1-A2 sectional drawing of Fig.1 (a).

  In FIG. 1A, the central axis L of the cage 1 is added. In the present embodiment, since the shape of the body portion of the cylindrical body 10 is cylindrical, the central axis L is an axis that passes through the center of the cylindrical body 10 on the XY plane and is parallel to the Z axis. In the present embodiment, the central axis L passes through the insertion port 14 and the center of the introduction path 11.

  With reference to FIGS. 1A to 1C, the cage 1 includes a cylindrical body 10, a connector 20, and three screws 30. The cylindrical body 10 is made of a resin material and has a cylindrical shape with a small diameter on the Z-axis positive side. A circular introduction path 11 is formed on the positive side of the Z axis of the cylindrical body 10, and a conical inclined surface 12 continues to the introduction path 11. The introduction path 11 and the inclined surface 12 are concentric with the central axis L. Accordingly, the inclined surface 12 is inclined so as to approach the central axis L as it goes in the positive direction of the Z axis.

  On the inclined surface 12, three protrusions 12a extending along the generatrix are formed. The ridges 12a have substantially the same height over the entire length. The ridges 12a are arranged at three places that are equiangular around the Z axis. The cross-sectional shape of the protrusion 12a in the direction perpendicular to the bus bar is a shape whose width becomes narrower toward the top. In the present embodiment, the cross-sectional shape of the ridge 12a is an isosceles triangular mountain shape, but may be another shape such as an arc shape or a trapezoidal shape. The ridge 12a is formed over the entire length of the bus bar.

  The inside of the cylindrical body 10 on the Z axis negative side with respect to the inclined surface 12 is a cylindrical space having the same diameter. The cylindrical body 10 is formed with rectangular openings 13 arranged in the circumferential direction. By these openings 13, the inside of the cylindrical body 10 is opened to the outside. Also, three screws 30 are fastened to the negative side of the cylindrical body 10 on the Z axis. The opening 13 at the position where there is no screw 30 on the negative side of the Z-axis extends to the vicinity of the end of the cylindrical body 10 on the negative side of the Z-axis, and the opening 13 where the screw 30 is located on the negative side of the Z-axis is in front of the screw 30. It extends to.

  The three screws 30 are respectively arranged at three positions that are equiangular around the Z axis. As shown in FIG. 1B, the screw 30 is disposed at an intermediate position between the two protrusions 12a when viewed in the positive direction of the Z-axis. The cylindrical portion 10 is formed with a screw hole (not shown) penetrating inside at a position where the screw 30 is disposed. The screw 30 is attached to the cylindrical body 10 by screwing the screw 30 into the screw hole. In the present embodiment, the screw 30 is made of a metal material, but may be made of another material such as a resin material. Further, the screw hole may be provided by a method of embedding a screw receiver such as a nut in the tubular body 10 in addition to a method of directly threading the tubular body 10.

  The end 30a of the screw 30 has a diameter that decreases toward the tip. In the present embodiment, the shape of the end 30a of the screw 30 is a hemispherical shape, but may be other shapes such as a convex spherical surface, a convex curved surface, or a conical shape. When the end 30a of the screw 30 has these shapes, the end 30a of the screw 30 makes point contact with the outer surface of the medical device when the outer surface of the cylindrical medical device is pressed with the screw 30 as described later. Will do. In addition, the end portion of the screw 30 may be a plane perpendicular to the longitudinal direction of the screw 30. In this case, the end portion of the screw 30 comes into line contact with the outer surface of the medical device when the outer surface of the tubular medical device is pressed.

  An insertion port 14 is formed at the end on the negative side of the Z axis of the cylindrical body 10, and the inside of the cylindrical body 10 is opened in the negative direction of the Z axis by the insertion port 14. The insertion port 14 is a circle having the same diameter as the inside of the cylindrical body 10, and the central axis L passes through the center thereof. That is, the insertion port 14 is concentric with the introduction path 11 and the inclined surface 12.

  The connector 20 is a metallic circular pipe, and is press-fitted and fixed to the positive side of the Z axis of the cylindrical body 10. The inner diameter of the connector 20 is the same as the diameter of the introduction path 11. The connector 20 is arranged so that the center axis L passes through the center thereof. Therefore, the connector 20 is concentric with the introduction path 11, and the inside of the connector 20 is connected to the introduction path 11. As will be described later, the connector 20 is connected to a tube 3 (see FIG. 2A) for supplying a cleaning liquid.

  In the present embodiment, the connector 20 is separate from the cylindrical body 10, but the connector 20 may be formed integrally with the cylindrical body 10. The connector 20 corresponds to a “connecting portion” described in the claims.

  FIG. 2A is a side view showing a state where the medical instrument 2 is held by the holder 1 and the tube 3 is attached. 2B to 2D are a B1-B2 cross-sectional view, a C1-C2 cross-sectional view, and an A1-A2 cross-sectional view, respectively, of the cage 1 in the state of FIG. 2A.

  The medical device 2 has an elongated lead tube shape. The medical instrument 2 is inserted in the positive direction of the Z axis from the insertion port 14 until the front end in the insertion direction comes into contact with the protrusion 12a and stops. At this time, the front end of the medical instrument 2 is guided by the ridge 12 a and positioned at a position that is substantially concentric with the introduction path 11. The front end of the medical device 2 rests on the ridge 12a and is separated from the inclined surface 12 by the height of the ridge 12a. In this state, the three screws 30 are tightened, and the outer surface of the medical device 2 is pressed by the screws 30 at three points in the circumferential direction. Thus, the medical instrument 2 is locked at a position along the central axis L of the cage 1 as shown in FIGS.

  In this state, as described later, the cage 1 is accommodated in the basket of the medical washer and cleaning is started. The other end of the tube 3 is connected to a cleaning liquid supply port (not shown) of the medical cleaning machine. When the cleaning liquid is sprayed into the basket from above and below the basket, the sprayed cleaning liquid is guided to the outer surface of the medical device 2 through the opening 13 of the holder 1. Thereby, the outer surface of the medical instrument 2 is cleaned. At this time, since the outer surface of the medical instrument 2 is only slightly point-contacted with the end 30a of the hemispherical screw 30, the entire region can be thoroughly cleaned. Similarly, since the front end of the medical instrument 2 is only slightly point-contacted with the three protrusions 12a, the entire region can be cleaned without leaving an entire area.

  Further, when the cleaning liquid is supplied from the tube 3, the cleaning liquid passes through the introduction path 11 and is then jetted toward the front end of the medical device 2 as a jet flow. Thus, the cleaning liquid flows into the medical instrument 2 and the inside of the medical instrument 2 is cleaned. Thereby, as for the medical device 2, the outer side surface and the inside of a pipe | tube are cleaned beautifully.

  FIGS. 3A to 3C are diagrams illustrating the operation of the cage 1 when the medical device 2 having a small diameter is attached to the cage 1.

  As shown in FIG. 3A, when the diameter of the medical device 2 is small, the front end of the medical device 2 may come off the ridge 12a and enter between the two ridges 12a. In this case, the front end of the medical instrument 2 abuts on the inclined surface 12. Thereafter, when the medical instrument 2 is further inserted, the front end of the medical instrument 2 is guided by the inclined surface 12 and gradually adjusted to a posture parallel to the Z axis. In the meantime, the front end of the medical device 2 rides on the ridge 12a, and thereafter, is guided by the ridge 12a. Thus, when the medical instrument 2 is pushed to the end, the medical instrument 2 assumes a posture along the central axis L as shown in FIG. Thereafter, the three screws 30 are tightened, and the medical device 2 is locked at a position along the central axis L as shown in FIG.

  In this state, the front end of the medical instrument 2 is substantially directly opposed to the introduction path 11. Therefore, the cleaning liquid ejected from the introduction path 11 is smoothly introduced into the medical instrument 2. In this case as well, the outer surface and the inside of the tube of the medical instrument 2 are cleaned by the cleaning liquid guided through the opening 13 and the cleaning liquid ejected from the introduction path 11. Further, the outer portion of the cleaning liquid sprayed from the introduction path 11 leaks to the outer surface of the front end of the medical device 2 through the gap between the front end of the medical device 2 and the inclined surface 12. As a result, the outer surface near the front end of the medical device 2 is cleaned.

  In addition, when the diameter of the medical instrument 2 is small as shown in FIGS. 3A to 3C, the cleaning liquid does not leak because a part of the cleaning liquid leaks to the outer surface of the medical instrument 2 as described above. Compared to the case, the pressure applied to the inside of the medical instrument 2 having a small diameter is reduced, and the force with which the medical instrument 2 is pushed in the direction in which the cleaning liquid is ejected is reduced. Thereby, even if it is the structure which hold | suppresses and supports the medical device 2 at three points with the three screws 30, the medical device 2 with a small diameter can be latched appropriately.

  FIG. 4 is a diagram illustrating an operation of the cage 1 when the medical device 2 having a large diameter is attached to the cage 1.

  When the diameter of the medical device 2 is large, it is difficult for the front end of the medical device 2 to enter between the two ridges 12a. Normally, the front end of the medical device 2 is guided by the three ridges 12a and is located at the innermost position. Is positioned. In this state, the three screws 30 are tightened, and the medical instrument 2 is locked at a position along the central axis L as shown in FIG.

  In the cage 1 of the present embodiment, a negative pressure is applied to the inside of the tube near the front end of the medical device 2 by Bernoulli's law due to the flow of the cleaning liquid traveling from the introduction path 11 into the medical device 2. As a result, the cleaning liquid that has flowed from the opening 13 flows through the gap between the front end of the medical device 2 and the inclined surface 12 and into the tube from the outer surface of the front end of the medical device 2. The inner surface near the front end of the medical instrument 2 is cleaned by the cleaning liquid flowing in this way. Therefore, in the present embodiment, the outer surface and the inside of the medical device 2 having a large diameter are cleanly cleaned by the cleaning solution injected into the tube of the medical device 2 and the cleaning solution flowing into the tube from the outer surface of the front end of the medical device 2. Can be washed.

  FIG. 5 is a diagram illustrating a configuration example when the medical instrument 2 is cleaned by the medical cleaning machine 200 using the holder 1 according to the embodiment. FIG. 5 schematically shows a state where the inside of the medical cleaning machine 200 is seen through.

  The medical cleaning machine 200 includes a cleaning basket 210 and a rack 100. The front side (X-axis negative side) of the cleaning bowl 210 is closed by a door (not shown). The rack 100 can be pulled out from the washing basket 210 in the negative direction of the X axis by opening the door. The rack 100 is provided with three stacking areas S in the vertical direction, and a net-like basket 110 is stacked in each stacking area S.

  An injection arm 220 is provided on each of the upper and lower portions of the cleaning bowl 210. A supply unit 230 for supplying the cleaning liquid to the rack 100 is provided on the side surface on the positive side of the Z axis of the cleaning bowl 210. The cleaning liquid is supplied to the spray arm 220 and the supply unit 230 via the pipe 240.

  The upper and lower injection arms 220 are supported so as to be rotatable around an axis parallel to the Y axis. In addition, the upper and lower spray arms 220 are provided with a large number of holes arranged in the longitudinal direction for spraying the cleaning liquid toward the rack 100. The upper and lower spray arms 220 rotate in the horizontal direction by the pressure of the cleaning liquid while spraying the cleaning liquid supplied through the pipe 240 toward the rack 100.

  In addition, in the rack 100, the injection arms 120 are respectively disposed below the upper two stacking areas S so as to be rotatable around an axis parallel to the Y axis. The spray arms 120 are provided with a large number of holes for spraying the cleaning liquid in the upward direction so as to be aligned in the longitudinal direction. The cleaning liquid is supplied to the two ejection arms 120 via a pipe 130 provided in the rack 100. That is, when the rack 100 is pushed into the innermost position in the cleaning bowl 210, the supply unit 230 disposed on the side surface of the cleaning bowl 210 is connected to a water supply port (not shown) of the rack 100. As a result, the cleaning liquid can be introduced into the pipe 130 through the water supply port. When the cleaning liquid is supplied to the spray arm 120 via the pipe 130, the spray arm 120 sprays the cleaning liquid upward while rotating due to the pressure of the cleaning liquid.

  In addition, the rack 100 is provided with a plurality of connectors 140 for supplying the cleaning liquid to the tubes 3 for each stacking area S. A cleaning liquid is supplied to the connector 140 via the pipe 130. One end of the tube 3 is connected to the connector 140, and the other end is connected to the connector 20 of the retainer 1 (see FIG. 1A).

  At the time of cleaning the medical instrument 2, after mounting the medical instrument 2 on the holder 1 as described above, the rack 100 is pulled out and the tube 3 connected to the connector 140 on the rack 100 side is connected to the connector of the holder 1. 20 (see FIG. 1A). Thereafter, the medical device 2 attached to the holder 1 is accommodated in the basket 110 loaded in the loading area S together with other medical devices. In FIG. 5, for convenience, only the medical instrument 2 attached to the holder 1 is illustrated, but each basket 110 also accommodates other medical instruments constituting the set.

  After the medical instrument 2 and other medical instruments are accommodated in each basket 110 in this way, the rack 100 is pushed to the innermost part in the cleaning basket 210 to close the door. Thereafter, when the operator performs an operation for starting the cleaning, the cleaning operation of the medical cleaning machine 200 is started. During the cleaning operation, the cleaning liquid is sprayed from above and below by the spray arms 120 and 220 to each stacking area S. Thereby, the outer surface of the medical device 2 and other medical devices housed in each basket 110 is cleaned. Further, as described above, the inside of the circular medical device 2 is cleaned by the cleaning liquid supplied to the holder 1 via the tube 3. In this way, the medical device 2 and other medical devices housed in each basket 110 are smoothly washed. When the cleaning operation is completed, high temperature steam is supplied to the cleaning bowl 210 to perform a sterilization operation, and then hot air is supplied to the piping 240 to perform a drying operation. Also during the drying operation, since warm air is introduced into the medical device 2 through the tube 3, the inside of the medical device 2 is effectively dried.

<Effect of Embodiment>
According to the embodiment, the following effects can be achieved.

  By storing the holder 1 holding the medical device 2 by connecting the tube 3 to the connector 20 in the basket 110, the inside and the outer surface of the tubular medical device 2 can be smoothly smoothed only by the cleaning operation by the medical cleaning machine 200. Can be washed. That is, the inside of the medical instrument 2 is cleaned by the flow of cleaning liquid injected from the introduction path 11, and the outer surface is cleaned or introduced into the cage 1 from the top and bottom of the basket 110 through the opening 13. The cleaning liquid is sprayed from the cleaning liquid. At this time, the front end of the medical device 2 is not covered because it is received by the protrusion 12a. Therefore, the front end of the medical device 2 is thoroughly cleaned with the cleaning liquid. Moreover, since the outer surface of the medical device 2 is pressed and locked by the screw 30 at three points, the outer surface is not substantially covered. Therefore, the outer surface of the medical device 2 is also thoroughly cleaned with the cleaning liquid entering from the opening 13.

  Further, even when the diameter of the medical instrument 2 inserted from the insertion port 14 is small, the front end is guided by the inclined surface 12 as shown in FIGS. Easy to be positioned. For this reason, the cleaning liquid sprayed from the introduction path 11 can be smoothly guided from the front end of the medical instrument 2 to the inside.

  In addition, since the front end of the medical device 2 is received by the protrusion 12a, the contact between the protrusion 12a and the front end of the medical device 2 is a substantially point contact, and the front end of the medical device 2 is in a state of floating from the inclined surface 12. For this reason, the cleaning liquid easily flows from the opening 13 to the front end of the medical instrument 2, and the front end of the medical instrument 2 can be cleaned by this cleaning liquid.

  Further, when the diameter of the medical instrument 2 is large, a negative pressure is generated in the tube near the front end of the medical instrument 2 due to the flow of the cleaning liquid that proceeds from the introduction path 11 into the medical instrument 2. As a result, as shown in FIG. 4, the cleaning liquid flowing from the opening 13 flows into the tube from the outer surface of the front end of the medical device 2 through the gap between the front end of the medical device 2 and the inclined surface 12. . By this inflow, the inner surface near the front end of the medical device 2 can be cleaned.

  When the diameter of the medical device 2 is small, as shown in FIG. 3C, the outer portion of the cleaning liquid sprayed from the introduction path 11 passes through the gap between the front end of the medical device 2 and the inclined surface 12. Leak to the outer surface of the medical device 2. Thereby, the outer surface of the front end of the medical instrument 2 is cleaned. Furthermore, since a part of the cleaning liquid leaks to the outer surface of the medical instrument 2 in this way, the pressure applied to the inside of the medical instrument 2 having a small diameter is reduced as compared with the case where the cleaning liquid does not leak. The force with which the medical instrument 2 is pushed in the ejection direction is reduced. Thereby, even if the medical device 2 is pressed and supported by the three screws 30 with a weak force, the medical device 2 having a small diameter can be appropriately locked.

  Moreover, since the three or more protrusion 12a is provided in the inclined surface 12 so that the center axis | shaft L of the holder | retainer 1 may be enclosed, the front end of the medical device 2 can be received only by the protrusion 12a. Thereby, the front end of the medical instrument 2 and the inner surface near the front end can be reliably washed.

  Further, as shown in FIG. 1 (d), the protrusion 12a has a mountain-shaped cross-sectional shape whose width decreases toward the top, so that the contact area of the front end of the medical device 2 with respect to the protrusion 12a can be reduced. For this reason, the front end of the medical instrument 2 and the inner surface near the front end can be reliably washed.

  In addition, since the diameter of the end portion 30 a of the screw 30 decreases toward the tip, the end portion 30 a of the screw 30 comes into substantially point contact with the outer surface of the medical device 2. For this reason, unwashed portions do not occur at the contact points with the screw 30 on the outer surface of the medical device 2.

  In addition, since the three screws 30 are arranged radially so as to surround the central axis L of the cage 1, the medical instruments 2 having different diameters can be locked at positions along the central axis L.

<Example of change>
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the embodiments of the present invention can be variously modified in addition to the above.

  FIG. 6A is a partial side view showing the configuration of the cage 1 according to the first modification. FIG. 6B is a cross-sectional view taken along the line D1-D2 of FIG. In FIG. 6B, the alternate long and short dash line schematically shows the range of the inclined surface 12 with which the front end of the medical device 2 contacts.

  In the first modification, a groove 12b is formed on the inclined surface 12 in place of the protrusion 12a. Other configurations are the same as those in the above embodiment. Each of the three grooves 12b is provided at the position of the protrusion 12a of the above embodiment. That is, the groove 12b is provided to extend along the generatrix at an equiangular position in the circumferential direction of the inclined surface 12b. Here, the width and depth of the groove 12b are constant, but the groove 12b may have other shapes, for example, the shape of the groove 12b may be a fan shape in a top view.

  Also in the first modified example, when the diameter of the medical device 2 is small, the outer portion of the cleaning liquid sprayed from the introduction path 11 leaks to the outer surface of the medical device 2 through the groove 12b as in the above embodiment. Get out. Therefore, also in the modified example 1, the outer surface of the front end of the medical device 2 can be effectively cleaned as in the case where the protrusion 12a is provided as in the above embodiment, and the medical device 2 is removed by the three screws 30. It can be locked properly.

  When the diameter of the medical device 2 is large, the inside of the tube near the front end of the medical device 2 becomes a negative pressure due to the flow of the cleaning liquid flowing from the introduction path 11 into the medical device 2 as in the above embodiment. As a result, the cleaning liquid flowing from the opening 13 flows into the tube through the groove 12b from the outer surface of the front end of the medical device 2. Therefore, also in the modified example 1, the inner surface near the front end of the medical instrument 2 can be cleaned by this flow.

  In the first modification, three grooves 12b are provided, but the number of grooves 12b is not limited to this. However, in order to smoothly clean the front end of the medical device 2, it is desirable that three or more grooves 12 b are provided in the inclined surface 12 so as to surround the central axis L of the cage 1. Thereby, when the diameter of the medical instrument 2 is small, the outer portion of the cleaning liquid ejected from the introduction path 11 leaks to the outer surface of the front end of the medical instrument 2 evenly in the circumferential direction through the groove 12b. Thus, the outer surface of the front end of the medical device 2 is cleaned by this cleaning liquid. Further, when the diameter of the medical device 2 is large, the cleaning liquid flowing from the opening 13 flows evenly in the circumferential direction through the groove 12b to the inner surface near the front end of the medical device 2, and the cleaning liquid that has flowed in the front end of the medical device 2 The inner surface is cleaned over the entire circumference. In order to reduce the contact range of the front end of the medical device 2 with respect to the inclined surface 12, it is desirable to set the width of the groove 12b as wide as possible or to increase the number of grooves 12b as much as possible.

  FIG. 6C is a partial side view illustrating the configuration of the cage 1 according to the second modification. FIG.6 (d) is D1-D2 sectional drawing of FIG.6 (c). In FIG. 6D, the alternate long and short dash line schematically shows the range of the inclined surface 12 with which the front end of the medical device 2 contacts.

  In the modified example 2, only one protrusion 12a is provided, and the two protrusions 12a in the above embodiment are omitted. Other configurations are the same as those in the above embodiment. In the case of this configuration, the front end of the medical instrument 2 is received in contact with the protrusion 12a and the inclined surface 12. For this reason, the medical instrument 2 is positioned at a position displaced slightly upward (Y-axis positive direction) from the position directly opposite the introduction path 11. However, also in this case, the cleaning liquid sprayed from the introduction path 11 is introduced into the medical instrument 2 and the inside of the medical instrument 2 is cleaned. Further, a gap is formed between the front end of the medical instrument 2 and the inclined surface 12 by the protrusion 12a. For this reason, the effect by this clearance gap can be show | played similarly to the said embodiment.

  In the second modification, only one protrusion 12a is provided. However, two protrusions 12a may be provided so that the angle between the two protrusions 12a is an acute angle. In this case, the front end of the medical instrument 2 is received in contact with the two protrusions 12a and the inclined surface 12. Alternatively, four or more protrusions 12a may be provided so as to surround the central axis L. In this case, the front end of the medical device 2 is received in contact with only the protrusion 12a.

  FIG. 7A is a partially exploded side view showing the configuration of the cage 1 according to the third modification. FIG. 7B is a front view of the receiving tool 40, and FIG. 7C is a partial side view for explaining the operation of the cage 1.

  In the third modification, the tubular body 10a, the water tap 10b, and the receiving device 40 are combined. The cylindrical body 10a is formed by cutting away a portion on the positive side of the Z axis (a portion including the introduction path 11 and the inclined surface 12) of the cylindrical body 10 in FIG. The side edge is slightly extended in the Z-axis positive direction. A thread groove 10c for screwing the ring 42 of the receiving tool 40 is formed on the edge on the positive side of the Z axis of the cylindrical body 10a.

  The faucet 10b is made of a resin material and has a cylindrical shape whose height direction is parallel to the Z axis. In the water tap 10b, a circular introduction path 11 is provided at the center position. A cylindrical connector 20 is press-fitted and fixed on the positive side of the Z-axis of the water tap 10b. The inner diameter of the connector 20 is the same as the diameter of the introduction path 11. A thread groove 10d for screwing the ring 41 of the receptacle 40 is formed at the edge on the negative side of the Z-axis of the water tap 10b.

  The receiver 40 is a metal frame-like member, and has a structure in which three frame parts 43 are bridged between two rings 41 and 42 having different diameters. The outer periphery of the rings 41 and 42 is threaded in the circumferential direction. The rings 41 and 42 are arranged so as to be concentric with each other. As shown in FIG. 7B, the three frame portions 43 are arranged at positions that are equiangular in the circumferential direction of the rings 41 and 42. On the side of the central axis L of the frame portion 43, a protrusion 43 a having an isosceles triangle cross section is formed over the entire length of the frame portion 43.

  At the time of assembly, the ring 42 is screwed into the screw groove 10c of the cylindrical body 10a, so that the receiver 40 is attached to the cylindrical body 10a. Furthermore, the water faucet 10b is attached to the receptacle 40 by screwing the ring 41 into the screw groove 10d of the water faucet 10b. Thus, as shown in FIG. 7C, the assembly of the cage 1 is completed. In this state, the central axis L passes through the centers of the rings 41 and 42 and the centers of the introduction path 11 and the connector 20.

  In the third modification, the front end of the medical device 2 is received in contact with the protrusions 43a of the three frame portions 43. In this case, since the front end of the medical instrument 2 and the outer side surface thereof are exposed to the outside from the space between the frame parts 43, the front end of the medical instrument 2 and the outside thereof are compared with the case where the inclined surface 12 is provided as in the above embodiment. The cleaning liquid from the medical cleaning machine 200 is easily guided to the side surface. Therefore, the front end of the medical instrument 2 and its outer surface can be effectively cleaned. However, in the third modification, when the diameter of the medical instrument 2 is small, the front end of the medical instrument 2 may be fitted into the space between the frame parts 43. In order to prevent this, in the third modification, it is desirable to arrange four or more frame portions 43 to reduce the gap between the frame portions 43.

  FIG. 8A is an exploded side view showing the configuration of the cage 1 according to the modified example 4, and FIG. 8B is a side view for explaining the operation of the cage 1 according to the modified example 4.

  In the modified example 4, as in the modified example 3, the tubular body 10a, the water tap 10b, and the receiving device 40 are combined. However, unlike the modified example 3, the cylindrical body 10a is formed by cutting away the portion on the positive side of the Z axis of the cylindrical body 10a in FIG. Is left. Moreover, the hole 10e into which the edge part of the frame part 43 of the receiving tool 40 is press-fit is formed in the edge of the cylindrical body 10a in three places of the circumferential direction. The opening 13 of FIG. 1A is not formed on the side surface of the cylindrical body 10a.

  The receiver 40 of the modification 4 has a configuration in which the ring 42 shown in FIG. 7A is omitted and the end of the frame portion 43 extends in the negative Z-axis direction. For example, the linearly extending frame portion 43 is bent so as to approach the central axis L at the position of the ring 42 in FIG. 7A, and the frame portion 43 having a shape as shown in FIG. It is formed. As in the third modification of FIG. 7A, the frame portion 43 is arranged at an equal angular position around the central axis L.

  At the time of assembly, the receiving part 40 is attached to the cylindrical body 10a by press-fitting and fixing the end portions of the three frame parts 43 to the holes 10e of the cylindrical body 10a. Furthermore, the water faucet 10b is attached to the receptacle 40 by screwing the ring 41 into the screw groove 10d of the water faucet 10b. Thus, as shown in FIG. 8B, the assembly of the cage 1 is completed. In this state, the central axis L passes through the center of the insertion port 14 and the center of the ring 41, and the centers of the introduction path 11 and the connector 20.

  In the modified example 4, as in the modified example 3, the front end of the medical device 2 is received in contact with the protrusions 43a of the three frame parts 43. Also in this case, as in the third modification, when the diameter of the medical device 2 is small, the front end of the medical device 2 may be fitted into the space between the frame portions 43. In order to prevent this, in the fourth modification, it is desirable to arrange four or more frame portions 43 to reduce the gap between the frame portions 43. In the fourth modification, the outer surface of the medical device 2 is largely exposed due to the space between the adjacent frame portions 43. For this reason, in the fourth modification, the cleaning liquid from the medical cleaning machine 200 reaches the outer surface of the medical device 2 more effectively than in the above embodiment or the third modification. Therefore, the cleaning effect on the outer surface of the medical device 2 can be enhanced. In the fourth modification, the space between the adjacent frame portions 43 corresponds to the opening described in the claims.

  FIGS. 9A and 9B are a partial side view and an E1-E2 cross-sectional view showing the configuration of the cage 1 according to the modified example 5, respectively. FIG. 9C shows the cage 1 according to the modified example 5 cut at the position E1-E2 in FIG. 9A, and the Z-axis positive side portion of the cage 1 after cutting is viewed in the direction of the introduction path 11. FIG.

  In the above embodiment, as shown in FIG. 1A, the conical inclined surface 12 is formed at the end on the positive side of the Z axis inside the cylindrical body 10. On the other hand, in the modified example 5, the inclined surface 12 is omitted, and the end on the positive side of the Z axis inside the cylindrical body 10 is a flat surface 10f perpendicular to the central axis L, as shown in FIG. ing. Then, three right-angled triangular blades 15 connected to the plane 10f and the inner surface of the cylindrical body 10 are formed so as to extend radially from the central axis L. As shown in FIG. 9B, the three blades 15 are arranged at equal angular positions in the circumferential direction of the cylindrical body 10. Further, on the hypotenuse of the blade 15, a ridge 15a having an isosceles triangle cross section is formed over the entire length. Other configurations of the modified example 5 are the same as those in the above embodiment.

  In the fifth modified example, the front end of the medical device 2 is received in contact with the protrusions 15 a of the three blades 15. In this case, if the diameter of the medical device 2 is small, the front end of the medical device 2 may be fitted into the space between the blades 15. In order to prevent this, also in the fifth modification, it is desirable to arrange four or more blades 15 and make the gap between the blades 15 as small as possible. For example, as shown in FIG. 9 (d), six blades 15 can be arranged at equal intervals, or eight, twelve or more blades 15 can be arranged. FIG. 9D is an E1-E2 cross-sectional view in the case where the six blades 15 are arranged at equal intervals in the cage 1 of FIG. 9A.

  FIG. 10A is a partial side view showing the configuration of the cage 1 according to the modified example 6, FIG. 10B is a front view showing the configuration of the cage 1 according to the modified example 7, and FIG. ), (D) are partial side views showing the structure of the cage according to the modified example 8. FIG.

  When the diameter of the medical instrument 2 is large, it is desirable to provide means for sufficiently spreading the cleaning liquid sprayed from the introduction path 11 to the extent that it reaches the inner surface of the medical instrument 2. As this means, in the modified example 6 of FIG. 10A, the outlet of the introduction path 11 is an inclined surface 11 a having a smaller apex angle than the inclined surface 12. As a result, the ejection position of the cleaning liquid is displaced to the positive side of the Z axis as compared with the above embodiment, and as a result, the range of the sprayed cleaning liquid is wider than that of the above embodiment at the front end of the medical instrument 2. For this reason, the cleaning liquid is more easily applied to the inner surface of the front end of the medical instrument 2. In addition, a structure for widening the spread angle of the cleaning liquid after injection may be provided in the introduction path 11.

  Moreover, in the said embodiment, although the protrusion 12a was arrange | positioned in the equal angular position to the circumferential direction of the inclined surface 12, if the front end of the medical device 2 can be received appropriately by the protrusion 12a, it is not necessarily adjacent. The angles between the strips 12a do not have to be uniform. For example, the ridges 12a may be arranged as in Modification 7 of FIG. Similarly, as long as the medical instrument 2 can be appropriately locked by the screw 30, the angle between the adjacent screws 30 may not necessarily be uniform.

  Moreover, in the said embodiment, although the connector 20 was directly inserted in the tube 3, for example, like the modified example 8 of FIG.10 (c), (d), each fits in the connector 20 and the tube 3, respectively. A joint composed of the engaged portion 21 and the engaging portion 31 may be attached. If it carries out like this, the tube 30 can be simply attached with respect to the holder | retainer 1. FIG.

  In the above embodiment, the medical instrument 2 is locked by the screw 30, but the mechanism for locking the medical instrument 2 is not limited to this. For example, as shown in FIG. 11 (a), the medical device 2 may be locked by a mechanism in which a plate-shaped locking member 16 advances and retreats from three directions with respect to the central axis L like a diaphragm of a camera. Or as shown in FIG.11 (b), the medical device 2 may be latched by the mechanism in which the plate-shaped latching member 17 which has a rectangular recess in the center advances / retreats from the up-down direction. In these cases, a mechanism for advancing and retracting the locking members 16 and 17 and an operation unit for operating the mechanism are provided. The mechanism is configured to press the locking members 16 and 17 against the outer surface of the medical device 2 using a biasing means such as a spring, or to be configured to realize pressing and releasing of the locking members 16 and 17 with one touch. desirable. Further, it is desirable that the operation unit has a configuration that can be operated as easily as possible.

  Moreover, in the said embodiment, although the rectangular-shaped opening 13 was arrange | positioned in the circumferential direction of the holder | retainer 1, if the washing | cleaning liquid can be smoothly guide | induced to the inside of the holder | retainer 1, the shape and magnitude | size of the opening 13, The arrangement state is not limited to this. For example, as shown in FIG. 11 (c), a group of circular openings 13 arranged in the Z-axis direction may be arranged in the circumferential direction of the cage 10, or the side surface of the cage 1 has a mesh shape. Innumerable openings may be provided on the side surface of the cage 1.

  In the above-described embodiment and modified example, it is assumed that the tubular medical instrument 2 used for the operation is held by the cage 1, but the present invention is applicable to other medical instruments, endoscopes, and the like. The present invention can also be applied to a cage for cleaning a medical instrument. In addition, the retainer according to the present invention may be used when a tubular medical instrument is washed with a washing machine having another configuration without being limited to the medical washing machine as shown in FIG.
