Description

  The present invention relates to a syringe container for storing unnecessary chemical solution and gas sucked into 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. By moving the plunger to the top dead center in this state, the drug solution is sucked into the space formed by the barrel and the plunger in the syringe. 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.

It is formed so as to be able to communicate with the space in the portion 12.

Next, the manufacturing method of the container 1 for syringes comprised in this way is demonstrated.
First, the plug body 42 is fitted and arranged in the first housing portion 45 of the outer body 41, and then the valve body 43 is fitted and arranged in the second housing portion 46. Thereby, the valve member 13 is comprised. Next, the 2nd accommodating part 46 is inserted in the cylindrical part 27 of the base 11, and the convex part 46a is engaged with the recessed part 27a. Since the flange part 43b of the valve body 43 is interposed between the cylindrical part 27 and the outer body 41, the cylindrical part 27 and the outer body 41 are hermetically and integrally assembled.

  Next, the storage part 12 in which the piston 32 is inserted into the cylinder 31 is inserted into the cylindrical part 27 and is adhered or welded in an airtight manner. Thereby, the base part 11 and the storage part 12 are assembled airtight and integrally.

  Next, a tube connected to a suction device such as a vacuum pump is punctured from the base 11 into the plug body 42 and the valve body 43. Thereafter, the suction device is driven to suck the air in the reservoir 12 from the opening 41 a formed in the end surface 41 b of the outer body 41 of the valve member 13, and the piston 32 contacts the end surface 41 b of the outer body 41. Move until By these steps, the syringe container 1 is manufactured.

Next, the usage method of the container 1 for syringes comprised in this way 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 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 the space formed by the barrel 110 and the plunger in the syringe 100 by moving the plunger to the top dead center.

  When air is sucked into the syringe 100 during the suction of the drug solution, or when excess drug solution is sucked, unnecessary fluid is discharged into the syringe container 1. Specifically, as shown in FIG. 2, the needle portion 122 of the injection needle 112 is punctured into the valve body 43, and the projection portion 123 of the connecting portion 121 comes into contact with the projection portion 22 a of the first fixing portion 22 of the base portion 11. The needle 112 is inserted into the base 11 until the tip of the needle part 122 is disposed in the space 13a of the valve member 13.

  Next, the plunger is pushed toward the bottom dead center, and unnecessary fluid is discharged from the syringe 100 into the space 13a. At this time, the pressure in the space 13a increases due to unnecessary fluid discharged from the syringe 100. Thereby, the movable valve 43a of the valve body 43 is opened, the space 13a and the internal space of the storage part 12 are continuous, and unnecessary fluid moves to the inside of the storage part 12.

  At this time, the pressure in the reservoir 12 increases according to the amount of fluid flowing into the reservoir 12, and the piston 32 moves. When the piston 32 moves and the discharge of the fluid from the syringe 100 stops, the pressure difference between the space 13a and the storage unit 12 disappears, the movable valve 43a returns to the original position, and the internal space of the space 13a and the storage unit 12 changes. It is shut off by the movable valve 43a.

  Next, the user removes the injection needle 112 from the valve body 43. At this time, the valve body 43 is gradually restored by the restoring force from the part from which the needle part 122 is removed, and the hole formed by the puncture is closed, so that the space 13a is blocked and the discharged fluid is stored in the storage part. 12 can be stored in the space 13a. In this way, unnecessary fluid in the syringe 100 is discharged, and the syringe 100 can be used.

  Further, when the injection needle 112 is discarded after the syringe 100 is used, the needle portion 122 of the injection needle 112 is punctured into the valve body 43, and the projection portion 123 of the connecting portion 121 is the projection portion 22a of the first fixing portion 22. Then, the injection needle 112 is further press-fitted. Thereby, the tip of the injection needle 112 is punctured into the plug body 42 beyond the space 13a. At this time, the opening at the tip of the needle portion 122 is located in the plug body 42, the opening of the needle portion 122 is closed by the plug body 42, and the valve body 43 is in close contact with the periphery of the needle portion 122. The space 13a is blocked from outside air. For this reason, it is possible to discard the injection needle 112 and the syringe container 1 while the fluid remaining in the needle portion 122 is not leaked to the outside air and is held in the needle portion 122.

  According to the syringe container 1 configured in this manner, unnecessary fluid can be discharged from the syringe 100 into the storage unit 12. Moreover, the fluid to be discharged is not only the air in the syringe 100 but also the case where a chemical solution is contained in the air or the case where the excess medicine is discharged, the space 13a of the valve member 13 and the inside of the storage unit 12 Thus, the discharged fluid moves and can be stored in the storage unit 12. In addition, even if the discharged unnecessary fluid does not move into the storage portion 12 and remains in the space 13a, the valve body 43 seals the space 13a, so that the discharged fluid or the like is outside the syringe container 1. There is no risk of leakage.

  As described above, the syringe container 1 can discharge the unnecessary fluid in the syringe 100 from the syringe 100 safely and reliably without leaking the fluid discharged from the syringe 100. 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 addition, the syringe container 1 is a hole formed by puncturing a needle portion 122 and a tube that sucks air in the storage portion 12 at the time of manufacture, by using the stopper body 42 and the valve body 43 as a stopper formed of an elastic body. Need not be blocked separately.

  When the injection needle 112 is discarded, the syringe container 1 can be discarded together with the injection needle 112 by puncturing the injection needle 112 into the plug body 42 and the valve body 43. In this case, the opening at the distal end of the needle portion 122 is disposed in the plug body 42 so that the opening at the distal end of the needle portion 122 is closed and the valve body 43 is in close contact with the periphery of the needle portion 122. Therefore, leakage of the chemical solution in the needle portion 122 and the fluid in the space 13a to the outside can be prevented. In addition, since the distal end of the needle part 122 is disposed in the plug body 42, there is no possibility that the distal end of the needle part 122 contacts the user or the like.

  In addition, the syringe container 1 is provided with the elastically deformable plug body 42 and the valve body 43 on the primary side and the secondary side of the space 13 a, and fixes the base 11, the storage section 12, and the valve member 13, It is possible to manufacture with a simple configuration in which the air is sucked and the piston 32 is moved to the valve member 13 side. For this reason, the productivity of the syringe container 1 can be increased and the manufacturing cost can be reduced. 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 container 1 for syringes accommodates the air etc. which were discharged | emitted from the syringe 100 in the storage part 12 and the space 13a which were interrupted | blocked outside by the valve body 43, it also becomes possible to ensure high safety | security.

  As described above, according to the syringe container 1 according to the first embodiment of the present invention, fluids such as air and chemicals discharged from the syringe 100 can be safely stored, and the productivity is improved at low cost. It becomes possible to do.
