Description

  The present invention relates to a syringe container that contains a chemical solution or gas discharged from a syringe.

  When the drug solution is sucked from the ampule into the syringe, the plunger is inserted into the barrel of the syringe to the bottom dead center, and the injection needle is inserted into the ampule. In this state, the drug solution is sucked into the space formed by the barrel and the plunger in the syringe by moving the plunger to the top dead center. At this time, the air in the ampoule may be sucked together.

  When the drug solution is extracted from the vial into the syringe, first, air of the same volume as the volume of the drug solution extracted from the vial is sucked into the syringe, and then the injection needle is punctured into the elastic cap of the vial.

  Next, the plunger of the syringe is reciprocated to replace the air in the syringe and the drug solution in the vial. At this time, a small amount of air enters the syringe. Moreover, it may enter more than the amount of the desired chemical solution.

  In order to extract this air and make a desired amount of drug solution, the needle is pointed upward, the air is placed above the space in the syringe, and the plunger is pushed toward the bottom dead center. Work to remove air and excess chemicals.

  When such an operation of extracting air and excess chemical liquid from the inside of the syringe is performed, air and a small amount of chemical liquid or gas containing chemical liquid are discharged from the inside of the syringe and may adhere to the worker or may be scattered around. And cause contamination of the surrounding area. Moreover, when a chemical | medical solution has toxicity, there exists a possibility of causing the health hazard of an operator.

  Therefore, an air venting device that can vent air in the syringe while preventing the surrounding contamination in the work of venting air is known (for example, see Patent Document 1). This air venting device includes a space portion that stores a chemical solution in a container and a filter portion that can ventilate the air in the space portion, and is configured to be able to capture the chemical solution contained in the air by the filter portion. In addition, the air venting device is formed so that the chemical solution can be prevented from moving to the outside even if the container is inclined, etc., by projecting the communication pipe connecting the space portion and the filter portion from the inner surface of the space portion. Even if the operation of extracting the air from the syringe is performed, it is possible to prevent the surrounding contamination by the chemical solution.

The second opening 32 has an inner peripheral surface that is larger in diameter than the inner peripheral surface of the communication hole 33. In the second opening 32, a plurality of openings 37 are formed at equal intervals along the circumferential direction in a part thereof.

  The second opening 32 has an annular recess 38 formed on a part of its inner peripheral surface, for example, on the inner peripheral surface closer to the end than the plurality of openings 37. For example, the recess 38 has a semicircular cross-sectional shape. In addition, the outer peripheral surface 32 a of the second opening 32 is formed so that its outer diameter is slightly smaller than the other part of the base 21.

  The communication holes 33 are formed with the same diameter. The communication hole 33 is formed shorter than the length of the needle part 122 protruding from the connection part 121 of the injection needle 112.

  The attachment portion 34 is formed so as to fix the container 11 in an airtight manner. The attachment portion 34 is formed so as to be fixed to the container 11 by being welded to the container 11, for example.

  The valve portion 22 includes a fixed portion 41 that is fixed to the second opening portion 32, a first valve portion 42, and a second valve portion 43. The valve portion 22 is a check valve provided at an end portion of the base portion 21. Further, the valve portion 22 is sealed between the communication hole 33 and the container 11, and forms a space 44 that communicates with the communication hole 33 and the container 11.

  The fixing portion 41 is formed in a cup shape with one end closed, and the opening end portion is fixed to the second opening portion 32. For example, the fixing portion 41 is formed having a plurality of different outer diameters. Specifically, the fixing portion 41 is formed on the opening end side thereof, and is formed on the closed end side of the first fixing portion 46 whose outer diameter is formed to be the same as the inner diameter of the second opening portion 32. And a second fixing portion 47 formed so that the outer diameter of the portion adjacent to the first fixing portion 46 is the same as the outer diameter of the second opening portion 32. The fixing portion 41 is a space forming portion that forms a space 44 together with the valve portion 42 therein.

  In the first fixing portion 46, a plurality of openings 49 are formed at equal intervals along the circumferential direction in a part thereof. The opening 49 is formed so as to be able to face and communicate with the opening 37 of the second opening 32 at least partially when the fixing portion 41 is fixed to the second opening 32.

  The first fixed portion 46 has an annular convex portion 48 formed on a part of the outer peripheral surface thereof, for example, on the closed end side of the plurality of openings 49, in other words, on the outer peripheral surface on the second fixed portion 47 side. . For example, the convex portion 48 has a semicircular cross-sectional shape. The convex portion 48 is formed so as to be able to fit into the concave portion 38 of the second opening portion 32 when the fixing portion 41 is fixed to the second opening portion 32. Further, the first fixing portion 46 is formed such that the length in the axial direction is shorter than the length from the end of the second opening 32 to the communication hole 33.

  The second fixing portion 47 is formed so that the outer diameter of the fixing portion 41 on the closed end side is the same as the outer diameter of the second opening portion 32 adjacent to the first fixing portion 46. The outer peripheral surface 47 a of the second fixing portion 47 forms an annular groove portion that can fix the second valve portion 43 together with the outer peripheral surface 32 a of the second opening portion 32.

  The 1st valve part 42 is formed with the resin material which can be elastically deformed, and is formed in the column shape from which an outer diameter differs. The first valve portion 42 is a plug formed of an elastic body that can be punctured with the injection needle 112 and that can be closed after the puncture of the injection needle 112, and is a so-called rubber plug. is there.

  The first valve portion 42 has a disk-shaped first portion 51 whose outer diameter is substantially the same as or slightly larger than the inner diameter of the second opening 32, and the outer diameter of the first valve portion 42 is the first fixing portion. And a cylindrical second portion 52 formed to have a diameter substantially the same as or slightly larger than the inner diameter of 46.

  The length of the first portion 51 in the axial direction is slightly longer than the difference between the length from the end of the second opening 32 to the communication hole 33 and the length of the first fixing portion 46. The first part 51 is interposed between the second opening 32 and the first fixing part 46, so that the first part 51 is sandwiched between the second opening 32 and the first fixing part 46 and is airtightly fixed.

  The length of the second portion 52 in the axial direction is substantially the same as the length from the end of the first fixing portion 46 to the opening 49. The second portion 52 forms a space 44 inside the fixed portion 41 by its end surface and the inner surface of the fixed portion 41.

  The 2nd valve part 43 is formed in the cylindrical shape with the resin material etc. which have flexibility. More specifically, the second valve portion 43 is formed in a tubular shape, and the inner diameter thereof is slightly smaller than the outer diameters of the outer peripheral surfaces 32a and 47a of the second opening portion 32 and the second fixing portion 47. .

  The 2nd valve part 43 is arrange | positioned at the groove part formed by the outer peripheral surfaces 32a and 47a of the 2nd opening part 32 and the 2nd fixing | fixed part 47, The inner peripheral surface closely_contact | adheres to the outer peripheral surfaces 32a and 47a. . By providing the second valve portion 43 in the groove portion, the openings 37 and 49 and the gap between the second opening portion 32 and the second fixing portion 47 can be sealed by the inner peripheral surface thereof.

  The container 11 is a so-called pouch formed by laminating films formed of a resin material having flexibility. The container 11 is formed so that the periphery thereof is bonded and the inside thereof is hermetically sealed by being airtightly fixed to the base portion 21.

  The lid 12 is formed so as to be able to close the first opening 31 of the base 21. The lid portion 12 is adhered to the end surface of the first opening portion 31 to close the opening of the first opening portion 31. After the lid 12 is bonded and the first opening 31 is closed, the lid 12 is sterilized by, for example, radiation sterilization, so that the lid 12 keeps the inside of the container 11 until the lid 12 is peeled off. It is formed so that it can be kept sterile.

Next, the usage method of the comprised container 1 for syringes is demonstrated.
First, the syringe 100 is filled with a chemical solution. Specifically, when the drug solution is sucked into the syringe 100 from the ampule, the operator inserts the plunger 111 into the barrel 110 of the syringe 100 to the bottom dead center and inserts the injection needle into the ampule. In this state, the drug solution is sucked into a space formed by the barrel 110 and the plunger 111 in the syringe 100 by moving the plunger 111 to the top dead center. When air is also sucked into the syringe 100 during the suction of the drug solution, the lid 12 is first removed from the first opening 31.

  Next, as shown in FIG. 6, the injection needle 112 is inserted into the spout portion 10 until the projection 123 of the connecting portion 121 contacts the inner peripheral surface of the first opening 31 of the spout portion 10. As a result, the injection needle 112 passes through the communication hole 33 and is punctured into the first valve portion 42. At this time, the tip of the needle part 122 penetrates the first valve part 42 and is located in the space 44.

  Next, the syringe container 1 and the syringe 100 are tilted so that the injection needle 112 is positioned above. That is, the syringe container 1 and the syringe 100 are arranged so that the syringe 100 moves downward along the direction of gravity of the syringe container 1. Thereby, the air in the syringe 100 moves to the injection needle 112 side.

  Next, the operator pushes the plunger 111 into the barrel 110 and discharges the air in the syringe 100 from the injection needle 112. Thereby, air (gas) containing air, chemical liquid or a part of the chemical liquid (air etc.) is discharged into the space 44. When air or the like moves in the space 44, the pressure in the space 44 increases, and the second valve portion 43 is pressed through the openings 37 and 49 due to the increase in pressure. The space 44 and the inside of the container 11 communicate with each other at a distance from 32a and 47a. Air or the like in the space 44 moves into the container 11 until the pressure in the space 44 becomes equal to the pressure in the container 11. When air or the like in the space 44 moves into the container 11, the second valve portion 43 seals the openings 37 and 49 by the restoring force, and the space 44 and the inside of the container 11 are shut off.

  Next, the operator removes the syringe 100 from the syringe container 1. Thereby, the first valve portion 42 closes the hole formed by the puncture of the injection needle 112 by its own restoring force, and the space 44 is blocked from the communication hole 33. Thereby, the air venting operation of the syringe 100 is completed.

  According to the syringe container 1 configured as described above, the air in the syringe 100 is discharged to the container 11 by the air venting operation of the syringe 100, and the air can be extracted from the syringe 100. Further, when the discharged air contains a chemical solution, or even when the chemical solution is discharged together when the air is discharged, it can move from the space 44 into the container 11 and be discharged into the container 11. It becomes. In addition, even if a part of the air discharged into the space 44 does not move into the container 11 and remains in the space 44, the first valve portion 42 blocks the space 44 and the communication hole 33. There is no risk of air leaking outside.

  Thus, the syringe container 1 can discharge the air sucked into the syringe 100 together with the drug solution from the syringe 100 safely and reliably without leaking the discharged air or the like. For this reason, it becomes possible to prevent the influence on an operator and the surrounding contamination by the leakage of a chemical | medical solution, etc.

  In the syringe container 1, the hole formed by the puncture of the needle portion 122 needs to be separately closed in order to block the space 44 and the communication hole 33 by using the first valve portion 42 as a stopper formed of an elastic body. There is no. For this reason, the container 1 for syringes has good workability.

  Further, when the syringe needle 112 can be removed from the syringe 100 after the syringe 100 is deflated and the syringe needle 112 can be discarded, the syringe container 1 can be discarded together with the syringe needle 112. Specifically, as shown in FIG. 7, the injection needle 112 is further inserted into the first opening 31. By this insertion, the protrusion 123 is elastically deformed. Thereafter, by rotating the syringe 100, the protrusion 123 of the connecting part 121 and the protrusion 36 of the first opening 31 are engaged, and the movement of the connecting part 121 in the rotational direction is restricted. At this time, the needle portion 122 is held with a predetermined holding force by the restoring force of the first valve portion 42, and the protruding portion 123 is fitted into the first opening portion 31. As a result, the barrel 110 and the connecting portion 121 are disengaged, but the state where the injection needle 112 is fixed to the first valve portion 42 is maintained, and the injection needle 112 is fixed integrally to the syringe container 1. It becomes possible to discard the injection needle 112 together with the syringe container 1.

  In this case, the space 44 communicates with the outside through the hole of the needle portion 122, but the space 44 is blocked from the inside of the container 11 by the second valve portion 43, and the pressure in the container 11 is reduced. It does not enter the space 44, and the gas and the chemical solution in the space 44 do not leak outside.

  Further, in this case, by setting the shape of the first opening 32 so that the connecting portion 121 is accommodated in the first opening 32, the removed injection needle 112 is arranged in the base 21. The first opening 32 can be closed by the lid 12 or a cap (not shown). Accordingly, even when the syringe container 1 including the injection needle 112 is discarded, the injection needle 112 can be prevented from being exposed to the outside. Furthermore, when the drug is highly toxic and the exposure of the drug in the space 44 and the injection needle 112 to the outside is not allowed, the syringe 100 is again inserted into the syringe container 1 after the drug in the syringe 100 is used. It becomes possible to install. Thereby, the syringe 100 and the syringe container 1 can be safely discarded together.

  The syringe container 1 may have a simple configuration in which the elastically deformable first valve portion 42 and the second valve portion 43 are provided on the primary side and the secondary side of the space 44. For this reason, it also becomes possible to reduce the manufacturing cost of the container 1 for syringes. In particular, since the syringe container 1 is discarded after use, it is possible to reduce the running cost when used in a medical field or the like.

  Moreover, since the air etc. discharged | emitted from the injection device 100 are accommodated in the container 11, and the inside of the container 11 is interrupted | blocked by the two valve parts 42 and 43 with the exterior, high safety | security can also be ensured. It becomes possible.

  As described above, according to the syringe container 1 according to the first embodiment of the present invention, fluid such as air discharged from the syringe 100 can be safely stored in the container 11 and the manufacturing cost can be reduced. Reduction is possible.
