The body 70 includes a first accommodating portion 76 that removably accommodates the intradermal needle 12 before use of the intradermal needle 12 by the internal partition wall 74, and a needle tube 14 that is not used after the intradermal needle 12 is used. A space is partitioned into a second accommodating portion 78 that can be accommodated and held in an exposed state. Hereinafter, a state in which the intradermal needle 12 is in the first housing portion 76 is referred to as a pre-use state, and a state in which the intradermal needle 12 is in the second housing portion 78 is referred to as a post-use state.

Specifically, the container body 70 includes the partition wall 74, the first cylindrical wall 80 extending in the axial direction from the outer peripheral edge portion of the partition wall 74, and the axial direction extending from the outer peripheral edge portion of the partition wall 74 to the other axial direction. And a second cylindrical wall 82 existing. The first accommodating portion 76 is configured by the partition wall 74 and the first cylindrical wall 80, and the second accommodating portion 78 is configured by the partition wall 74 and the second cylindrical wall 82.

The axial length of the first housing portion 76 (extension length of the first cylindrical wall 80) is longer than the axial length of the intradermal needle 12. The first accommodating portion 76 communicates with a first opening 77 provided at one end of the container body 70 in the axial direction (the end opposite to the partition wall 74). The first accommodating portion 76 can take out the intradermal needle 12 in a pre-use state through the first opening 77.

The inner surface of the first cylindrical wall 80 is formed with an inner diameter slightly larger than the diameter of the enlarged diameter portion 30 (including the pair of claw portions 36) of the needle hub 16 in a state before use. In addition, a plurality of guide surface portions 84 are formed on the inner surface of the first cylindrical wall 80 so as to bulge and are arranged at intervals in the circumferential direction. A guide groove 86 is formed between the guide surface portions 84, and a claw portion 36 is engageable with the back side of the guide groove 86 (near the upper edges of a plurality of ribs 92 described later). A joint convex portion 86a is provided.

That is, in the pre-use state, the intradermal needle 12 is lightly locked to the container body 70 due to the pair of claw portions 36 being hooked on the engaging convex portions 86a, and is unexpectedly dropped from the first accommodating portion 76. Is prevented. Further, the guide surface portion 84 sandwiching the pair of claw portions 36 of the intradermal needle 12 in a state before use restricts the rotation of the intradermal needle 12 around the axis.

A ring-shaped flange 88 that protrudes short radially outward and circulates in the circumferential direction is integrally formed on the protruding end 80a of the first cylindrical wall 80. A seal member 72 (see FIG. 1) is attached to the end surface 88a of the flange 88 adjacent to the first opening 77 over the entire circumferential direction. Thereby, the 1st opening part 77 (1st accommodating part 76) is sealed. Further, the end surface 88a of the collar portion 88 makes the container body 70 stand up (upright) well with respect to the mounting surface when the container body 70 is placed with the first opening 77 facing downward.

In the partition 74, a surface 74a constituting the first accommodating portion 76 is provided with a raised portion 90 where the partition 74 is raised toward the center. The protruding end portion of the raised portion 90 is provided with a recessed portion 90a that is recessed in the direction opposite to the protruding direction, and the needle tip 14a of the needle tube 14 is accommodated in the recessed portion 90a in a non-contact state before use.

A plurality of ribs 92 are integrally formed on the outer peripheral edge side of the partition wall 74. The plurality of ribs 92 are equally disposed along the circumferential direction of the partition wall 74. Each rib 92 stands upright from the partition wall 74 and protrudes from the inner surface of the first cylindrical wall 80 in the radial direction of the first cylindrical wall 80. In the pre-use state, the inner edge of each rib 92 contacts the side surface of the ring protrusion 32 of the intradermal needle 12, and the upper edge of each rib 92 contacts the tip surface 30 a of the enlarged diameter portion 30 of the intradermal needle 12. To do.

On the other hand, the 2nd accommodating part 78 is connected to the 2nd opening part 79 provided in the other end part (end part on the opposite side to the partition 74) of the axial direction of the container 70, as shown to FIG. 4A. . In other words, the first opening 77 and the second opening 79 are provided at positions opposite to each other in the axial direction of the container body 70. The axial length of the second accommodating portion 78 (the extending length of the second cylindrical wall 82) is shorter than the axial length of the first accommodating portion 76. That is, the second housing part 78 is formed shallower than the first housing part 76.

The inner peripheral surface of the second cylindrical wall 82 is formed to have an inner diameter slightly larger than the diameter of the enlarged diameter portion 30 (including the pair of claw portions 36) of the intradermal needle 12.

The protruding end 82a of the second cylindrical wall 82 constituting the second opening 79 circulates in a ring shape in the circumferential direction, and the thickness changes along the circumferential direction. A plurality of notches 82b are provided along the circumferential direction at a portion where the thickness of the protruding end 82a of the second cylindrical wall 82 is thin. The protruding end 82a of the second cylindrical wall 82 comes into contact with the mounting surface at a thick portion arranged in an annular shape when the container body 70 is mounted with the second opening 79 facing downward. Thereby, the container body 70 can be favorably erected (standing up).

And the 2nd accommodating part 78 has the latching | locking part 94 which latches the needle hub 16 when the intradermal needle 12 is accommodated. Specifically, the locking portion 94 is configured by a pair (a plurality) of locking pieces 96 protruding inward from the second cylindrical wall 82 that constitutes the second housing portion 78.

The pair of locking pieces 96 are provided at opposing positions (positions where the phase is shifted by 180 °) of the second cylindrical wall 82. Each locking piece 96 protrudes obliquely inward from the position near the protruding end 82 a of the second cylindrical wall 82 toward the partition wall 74. The protrusion amount at which the protruding end 96a of each locking piece 96 protrudes inward in the radial direction is sufficiently larger (for example, twice or more) than the protrusion amount of the engagement protrusion 86a of the first housing portion 76. The second cylindrical wall 82 has a small window 97 (see FIG. 1) in which the locking piece 96 is disposed, and allows elastic deformation of the locking piece 96 to the outside.

The distance between the projecting ends 96a of the pair of locking pieces 96 and the surface 74b of the partition wall 74 is approximately the same as the dimension obtained by adding the projecting length of the ring projecting portion 32 of the intradermal needle 12 and the thickness of the enlarged diameter portion 30. Is set. Further, the protruding end 96 a of each locking piece 96 has an end surface parallel to the partition wall 74 in a state where it is not elastically deformed. When the intradermal needle 12 is accommodated in the second accommodating portion 78, each locking piece 96 is elastically deformed outward with the contact of the enlarged diameter portion 30, and returns to its original position when the enlarged diameter portion 30 passes. To do. Therefore, each protruding end 96a faces the enlarged diameter portion 30 of the intradermal needle 12 in a state after use.

Further, the surface 74b of the partition wall 74 that constitutes the second housing portion 78 is provided with a recess 98 corresponding to the raised portion 90 of the first housing portion 76 described above, and circulates at a position away from the recess 98 by a predetermined distance. An annular guide portion 100 is provided. Further, the outer side of the surface 74b from the guide portion 100 is formed flat.

The concave portion 98 accommodates the needle tube 14 and the shaft portion 28 in a non-contact manner when the intradermal needle 12 is locked by the locking portion 94 (after use). The guide portion 100 functions as a mark that can guide the ring protrusion 32 when the intradermal needle 12 is inserted into the second housing portion 78. Furthermore, the guide part 100 contacts the inner side of the ring protrusion 32 in a state after use, and stabilizes the posture of the intradermal needle 12.

In addition, the 2nd accommodating part 78 may have a rotation control mechanism (not shown) which controls that the intradermal needle 12 of a used state rotates around an axis | shaft. The rotation restricting mechanism restricts the rotation of the intradermal needle 12 so that only the syringe 20 of the injection device 18 can be rotated and the mutual assembled state can be released. The rotation restricting mechanism can be realized, for example, by providing a protrusion that hooks the claw portion 36 at the same height position as the claw portion 36 in the used state on the inner surface of the second cylindrical wall 82.

The container 10 according to the present embodiment is basically configured as described above, and the operation thereof will be described below.

The container 10 is in a pre-use state in which the intradermal needle 12 is housed in the first housing portion 76 of the container 70 when the product is provided (see FIG. 1). As described above, in this state, the pair of claws 36 of the intradermal needle 12 is hooked on the engaging convex portion 86a, so that the intradermal needle 12 is prevented from falling off from the storage container 10. In addition, the container 10 seals the intradermal needle 12 by sealing the sealing member 72 to the collar portion 88 of the container body 70.

As shown in FIG. 1, the user places the container 70 so that the first opening 77 faces upward when the injection device 18 is used. At this time, the protruding end 82a of the second cylindrical wall 82 of the container body 70 causes the container body 70 to stand upright. Then, the user peels off the seal member 72 from the container body 70.

Thereafter, the distal end of the syringe 20 is inserted into the first accommodating portion 76, and the proximal end portion of the intradermal needle 12 and the distal end portion 42 of the syringe 20 are connected. The user grasps the holder 58 and inserts the nozzle 44 of the distal end portion 42 into the through hole 25 of the second member 24, and the female thread portion 47 of the distal end portion 42 becomes the male thread portion 40 of the intradermal needle 12. Screw in (see FIG. 2). At this time, the rotation of the intradermal needle 12 is regulated by the pair of claw portions 36 being hooked on the guide surface portion 84, and the screwing with the syringe 20 is smoothly realized.

When the connection between the intradermal needle 12 and the syringe 20 (assembly of the injection device 18) is completed, the user pulls the syringe 20 away from the storage container 10. The pair of claw portions 36 of the intradermal needle 12 and the engagement convex portion 86a of the container 10 are engaged with a weak engagement force, and the engagement is easily released in accordance with the pulling operation. Therefore, the intradermal needle 12 and the syringe 20 are taken out from the storage container 10 while being integrated.

Thereafter, the user punctures the living body with the needle tube 14 of the intradermal needle 12 and presses the plunger 56 in the puncture state. Thereby, the chemical solution stored in the storage space 61 of the syringe 20 is injected into the skin through the needle hole 15 of the needle tube 14.

After the injection of the chemical solution, the used intradermal needle 12 is discarded. At this time, the user houses the intradermal needle 12 in the second housing portion 78 of the housing container 10. Specifically, as shown in FIG. 4B, the user places the container body 70 in the opposite direction (the second opening 79 faces upward) and places the collar portion 88 of the first cylindrical wall 80 on the placement surface. Then, the container body 70 is made to stand upright (stand up).

Then, the intradermal needle 12 at the tip of the injection device 18 is accommodated in the second accommodating portion 78 through the second opening 79. Then, the user operates the ring protrusion 32 of the intradermal needle 12 while aiming at the guide portion 100 of the second housing portion 78. Thereby, the guide part 100 is guided so as to contact the inside of the ring protrusion 32. Further, the needle tube 14 of the intradermal needle 12 is smoothly guided to the recess 98 and is accommodated in a non-contact state with respect to the recess 98.

Further, when the intradermal needle 12 is inserted into the second housing portion 78, the pair of locking pieces 96 are elastically deformed by the contact of the enlarged diameter portion 30 of the intradermal needle 12, and after passing through the enlarged diameter portion 30, Return to the position. Accordingly, the pair of locking pieces 96 can be hooked on the enlarged diameter portion 30 of the intradermal needle 12 accommodated in the second accommodating portion 78.

Then, the user presses the needle hub 16 of the intradermal needle 12 with a finger or the like while rotating the syringe 20 relative to the intradermal needle 12 to detach the intradermal needle 12 and the syringe 20. As a result, as shown in FIG. 5, the container 10 is in a state where the intradermal needle 12 is held while the needle tube 14 is in an unexposed state after use.

In the post-use state, even if stress (external force or the like) is applied in the direction in which the intradermal needle 12 is removed from the second storage portion 78 of the storage container 10, the enlarged diameter portion 30 is caught by the pair of locking pieces 96. In particular, the pair of locking pieces 96 extends obliquely inward from the second cylindrical wall 82, and the protruding end 96 a faces the base end surface 30 b of the enlarged diameter portion 30 of the needle hub 16. For this reason, when the diameter-expanded portion 30 moves in the disengagement direction, the pair of locking pieces 96 are elastically deformed inward to restrict the disengagement of the diameter-expanded portion 30. That is, the storage container 10 makes it impossible to remove the intradermal needle 12 from the second storage part 78, in other words, the state after use can be continued well.

As described above, the storage container 10 according to the present embodiment includes the first storage portion 76 and the second storage portion 78, so that it is detached from the intradermal needle 12 and the first storage portion 76 when the product is provided. The intradermal needle 12 can be properly accommodated. That is, the first accommodating portion 76 allows the intradermal needle 12 to be easily taken out from the first opening 77. On the other hand, by inserting the detached intradermal needle 12 from the second opening 79 opposite to the first opening 77 into the second housing 78 and holding it by the second housing 78, the container 10 and the intradermal needle 12 are integrated, and it is possible to cover the needle tube 14 to prevent false puncture. That is, the storage container 10 can realize more reliable prevention of erroneous piercing and simplification of operation.

Further, the container 10 can firmly hold the intradermal needle 12 in the second housing part 78 by locking the needle hub 16 of the intradermal needle 12 by the locking part 94. Therefore, the unexposed state of the needle tube 14 is maintained, and the used intradermal needle 12 can be easily discarded.

In addition, the storage container 10 has a pair of locking pieces 96 so that when the intradermal needle 12 is inserted into the second storage portion 78, the pair of locking pieces 96 are elastically deformed to allow passage and pass. The needle hub 16 can be locked later by the elastic return of the pair of locking pieces 96. Therefore, the user only needs to perform an operation of inserting the intradermal needle 12 into the second accommodating portion 78, and the operation is further simplified.

Furthermore, the storage container 10 has a recess 98 for storing the needle tube 14 in a non-contact manner, so that the needle tube 14 can be prevented from being damaged when the intradermal needle 12 is stored in the second storage portion 78. Thereby, the used intradermal needle 12 can be reused satisfactorily after sterilization or the like.

And the container 10 can further simplify the insertion of the intradermal needle 12 into the second container 78 because the second container 78 is shallower than the first container 76. Further, the size of the entire storage container 10 is reduced, and the storage container 10 and the intradermal needle 12 can be easily transported.

Furthermore, the container 10 can be easily inserted into the second container 78 by supporting the standing state during use. Thereby, it becomes possible to prevent the needle tube 14 from being pierced more reliably.

The container 10 has the guide part 100 that can guide the ring protrusion 32 of the intradermal needle 12, so that the ring protrusion 32 and the guide part 100 can be positioned even if the ring protrusion 32 makes it difficult to see the needle tube 14. By matching, the intradermal needle 12 can be easily accommodated in the second accommodating portion 78.

In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible along the summary of invention. For example, the 2nd accommodating part 78 may be formed deeper than the said embodiment, and the structure which covers the intradermal needle 12 after use entirely may be sufficient as it.

Further, the configuration of the locking portion 94 that locks the intradermal needle 12 in the second housing portion 78 is not particularly limited. For example, the locking portion 94 can be configured such that three or more locking pieces 96 are provided in the circumferential direction of the second cylindrical wall 82. The locking portion 94 may adopt a convex portion or a concave portion (including a hole in which the claw portion 36 is inserted and locked) instead of the locking piece 96, or a hole is formed in the ring protrusion 32. Thus, a means for catching in the lateral hole may be provided. Further, as another locking portion 94, a configuration in which a female screw structure capable of being screwed to the outer peripheral edge (or claw portion 36) of the enlarged diameter portion 30 of the intradermal needle 12 is provided on the second cylindrical wall 82, friction fitting For example, the second cylindrical wall 82 may have a tapered surface that can be mated.

Furthermore, the second housing part 78 may have a needle puncture elastic member (not shown) through which the used needle tube 14 is punctured in the recess 98 or the like. The needle puncture elastic member may be configured to hold the needle tube 14 with a strong frictional force. In this case, the second cylindrical wall 82 may not have the engaging portion 94.

Also, the syringe 20 is not a prefilled syringe but may be used by filling with a chemical immediately before use.
