Description

[Detailed description of the invention]

[0001]

[Field of Industrial Application] The present invention relates to a container for disposing of used syringe needles.

【0002】

[Prior Art] Accidents of infection of third parties through injection needles used on patients for treatment of hepatitis B, AIDS, etc. have occurred, and this has become a social problem. This occurs when a third party accidentally injures his or her hand with an injection needle, resulting in an infection caused by bacteria in the residual liquid remaining at the tip of the injection needle. Therefore, great care must be taken when handling used injection needles.

[0003] In the past, glass syringes were sterilized and reused, but in addition to the above reasons, due to labor shortages and improvements in production technology, in recent years disposable systems have been introduced, which are typically disposed of after use. needles are used. Injection needles that are disposed of have a structure in which the needle portion is glued to a plastic hub that serves as an attachment port to the syringe body, and is used by fitting it into the syringe body. An apparatus for disposing of used injection needles without touching them is disclosed in Japanese Patent Application Laid-Open No. 2-88076.

[0004] In the syringe needle disposal container disclosed in JP-A-2-88076, when a used syringe needle is inserted into the separation port of the separation lid, the flange portion of the hub of the syringe needle is inserted into the separation port. It is locked on the periphery, and when the syringe barrel is lifted and pulled out in this locked state, the injection needle comes off the syringe barrel and falls into the container body.

[0005]

[Problems to be Solved by the Invention] However, upon further detailed research by the inventors, it was found that the above-mentioned injection needle disposal container has the following difficulties. That is, when disposing of a used injection needle, in the above-mentioned injection needle disposal container, the injection needle is inserted into the separation port of the separation lid, and the flange part of the hub of the injection needle is locked to the periphery of the separation port. In this state, by pulling the syringe barrel out, the needle is removed from the syringe barrel and dropped into the container body.

[0006] At this time, it is necessary to pull the syringe barrel with one hand and hold the container body with the other hand. Therefore, if the container body is not held down sufficiently, the used syringe may be pulled up along with the container body, which is dangerous. Furthermore, if the separation lid were to come off while the syringe barrel was being stretched, the used syringe would be pulled up with force with the needle exposed, which is very dangerous. In general, an upward pulling operation requires force and tends to be unstable.

[0007] The present invention has been made based on the results of such studies, and is a method for disposing of used needles, which allows dangerous used needles to be disposed of without touching them, and which can be disposed of with just one hand. The purpose is to provide a container. Another object of the present invention is to provide a used needle disposal container that can be disposed of without the need to forcefully pull the syringe upward.

[0008]

[Means for Solving the Problems] In order to achieve the above object, a used syringe needle disposal container according to the present invention includes a lid portion and a syringe needle accommodating portion, and the lid portion has a syringe needle removal portion inside. The syringe body is equipped with a syringe body push-up part on the outside, the needle removal part and the syringe body push-up part are arranged with a gap between them, and are movable in the direction of approach and separation, and the syringe body push-up part is arranged with respect to the needle removal part. , an elastic force is applied in the separating direction, and the syringe body pushing up part is formed with a syringe needle insertion hole into which the syringe needle can be freely inserted but the syringe barrel cannot be inserted, and the syringe needle removal part is formed with a syringe needle insertion hole through which the syringe barrel can be inserted. A needle removal hole is formed which is smaller in diameter than the peripheral edge of the proximal end and which allows the injection needle to be forcibly inserted only from the outside to the inside.

[0009]

[Function] In the used syringe disposal container according to the present invention, first, hold the syringe body of a used syringe and insert the syringe needle into the syringe needle insertion hole formed in the syringe body push-up part of the lid. do. After inserting the needle into the hole, if you push it further down,
The distance between the syringe needle removal part and the syringe body push-up part is shortened, and the syringe needle is inserted into the syringe needle removal hole formed in the syringe needle removal part. At this time, since the injection needle insertion hole is formed smaller than the diameter of the syringe barrel, only the injection needle can be inserted therethrough. Although the injection needle removal hole is smaller in diameter than the circumferential edge of the proximal end of the injection needle, it is forcibly opened by applying downward force, and the injection needle is forcibly inserted therethrough.

[0010] When the force applied to the syringe body is relaxed, the syringe body pushing part moves in a direction away from the syringe needle removal part due to the elastic force, and pushes the syringe body upward. However, since the periphery of the proximal end of the injection needle is locked by the injection needle removal hole, the injection needle cannot be pushed upward. The needle thus comes off the syringe body and falls into the needle receptacle. In other words, used needles can be disposed of easily and safely by simply holding the syringe body, inserting the needle into the needle insertion hole, applying downward force, and then relaxing the force. .

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 is a perspective view of a used syringe disposal container according to the present invention, FIG. 2 is a sectional view thereof, and FIG. 6 is a sectional view taken along line AA in FIG. The used needle disposal container 1 is composed of a lid part 2 and a needle storage part 3, and the lid part 2 has a needle removal part 4, a syringe body push-up part 5, a push-up spring 6, and an elastic locking member 7. It consists of On the other hand, the syringe 8 includes a syringe body 9 and a syringe needle 10.
The syringe main body 9 includes a syringe barrel 11 and a piston 12, and the syringe needle 10 includes a needle portion 13 and a hub 14.
It is composed of.

[0012] The used syringe needle disposal container 1 is a cylindrical container in which the lid portion 2 and the syringe needle accommodating portion 3 are separately molded, and has excellent durability, sealability, lightness, and economic efficiency. Plastics are preferably used. The lid part 2 is for removing the used injection needle 10 from the injection main body 9 and placing it into the injection needle storage part 3. A needle insertion hole 5a is formed in the syringe body push-up portion 5 of the lid 2, which is larger than the diameter of the flange 14a, which is the maximum diameter of the injection needle 10 and is the base end periphery of the hub 14, and smaller than the diameter of the syringe barrel 11. The injection needle insertion hole 5a allows the entire injection needle 10 to be inserted therethrough, and also prevents the insertion of the syringe main body 9.

[0013] The needle removal part 4 of the lid part 2 has a needle removal hole 4 smaller than the diameter of the flange 14a.
a is formed, and furthermore, a needle removal hole 4 is formed.
A groove 15 is formed radially around a (see FIG. 6). This allows the needle removal hole 4
A can be pushed open along the split groove 15 by applying downward force, allowing the injection needle to be forcibly inserted. Moreover, even after applying upward force,
Since the flange 14a is locked, the injection needle 10 can be prevented from slipping out of the container. The push-up spring 6 is for exerting an elastic force in the separating direction between the needle removal part 4 and the syringe body push-up part 5, and is used to apply an elastic force in the separating direction between the needle removal part 4 and the syringe body push-up part 5. There are three. The elastic force of the push-up spring 6 is
An elastic force equal to the force that removes the injection needle 10 from the syringe body 9 is preferred.

[0014] The elastic force locking member 7 locks the syringe needle removal part 4 and the syringe main body push-up part 5, which have elastic force by the push-up spring 6, and locks the syringe needle removal part 4 and the syringe body push-up part 5. Three pieces are equally provided between the syringe body push-up part 5 and the syringe body push-up part 5. In the normal state, the syringe main body push-up part 5 is pushed up from the syringe needle removal part 4 by the elastic force of the push-up spring 6, and the elastic force locking member 7
It is in a locked state by. The injection needle accommodating part 3 is a container into which the removed injection needle 10 is dropped, and a sterilization pad 16 for absorbing residual liquid is placed on the bottom surface to improve safety.

[0015] The syringe 8 includes a syringe body 9 and an injection needle 1.
It is composed of 0. The injection needle 10 is of a disposable system that is disposed of after use, and has a configuration in which a needle portion 13 is glued to a hub 14 that serves as an attachment port to the syringe main body 9. It is used by fitting. A flange 14a, which is a peripheral edge, is formed at the base of the hub 14.

[0016] A method of using the used syringe needle processing container 1 configured as described above will be explained based on the drawings. Cross-sectional views showing the usage state of the used syringe needle processing container 1 are shown in FIGS. 3, 4, and 5. First, insert the used syringe 8 into the needle insertion hole 5a formed in the syringe body push-up part 5 of the lid part 2.
Holding the syringe main body 9, insert the injection needle 10 from the tip (see FIG. 3). Even after inserting the injection needle 10 into the injection needle insertion hole 5a,
By further pushing downward against the elastic force of the push-up spring 6, the distance between the needle removal part 4 and the syringe body push-up part 5 is shortened, and the needle removal hole formed in the injection needle removal part 4 is closed. 4a forcibly inserts the injection needle 10 (see FIG. 4).

[0017] At this time, the injection needle insertion hole 5a is formed to be larger than the diameter of the flange 14a, which is the maximum diameter of the injection needle 10, and smaller than the diameter of the syringe barrel 11, so that the injection needle 10 can be completely inserted. Moreover, the syringe main body 9 can be locked on the outer surface side. Further, the injection needle removal hole 4a is located at the flange 14.
Although it is formed smaller than the diameter of a, since grooves 15 are formed radially around the circumference, by applying downward force, it is pushed open along the grooves 15.
The injection needle 10 can be forcibly inserted. Furthermore, even if an upward force is applied thereafter, the flange 14a is locked by the injection needle removal hole 4a, so the injection needle 10
prevent it from escaping outside the container.

[0018] Then, when the force applied downward is relaxed, the syringe main body push-up section 5 pushes the syringe main body 9 upward due to the elastic force. However, the needle 1
Since the flange 14a of the needle 0 is locked by the needle removal hole 4a, the needle is not pushed upward, but comes off from the syringe body 9 and falls into the needle accommodating portion 3 (see FIG. 5). The injection needle 10 falls onto the residual liquid suction sterilization patch 16 placed on the inner bottom surface of the injection needle storage part 3, thereby softening the impact of the drop and also absorbing the residual liquid and sterilizing it, thereby increasing safety. It is being The used syringe needle disposal container 1 is disposed of together with the discarded syringe needle 10 without removing the lid 2.

[0019] Modifications The design of the above embodiment can be modified as appropriate, and modifications will be explained based on the drawings. A perspective view of the used injection needle disposal container 1 according to this modification is shown in FIG. 7, and a cross-sectional view is shown in FIG. In the above embodiment, since the upper surface of the needle accommodating part 3 is completely open, after the injection needle 10 is disposed of and placed inside the syringe needle accommodating part 3, the lid part 2 is opened.
It is dangerous to remove the needle accommodating section 3 and treat only the needle accommodating section 3. Therefore, the syringe needle 1 that has been disposed of
0, it is preferable to dispose of the entire used syringe needle disposal container 1 without removing the lid part 2.

[0020] The used syringe needle processing container 1 of the modified example shown in FIGS. 7 and 8 does not completely open the top surface of the syringe needle accommodating portion 3, but has a small hole 3a that allows the syringe needle 10 to be inserted freely. Further, the spring 6 for pushing up the lid part 2 and the elastic force locking member 7 are integrally formed so that the upper surface of the injection needle accommodating part 3 does not become an obstruction. In this modified example, after the injection needle 10 is disposed of and placed inside the injection needle accommodating part 3, the lid part 2 is removed and the small hole 3a is sealed with a seal or the like. 10 and only the injection needle accommodating part 3 can be disposed of, and the lid part 2, which has a relatively complicated structure, can be reused.

[0021] In addition, the hub 1 of the injection needle 10 has the flange 14a locked by the injection needle removal hole 4a.
By providing a mechanism for rotating the syringe 4, the elastic force of the push-up spring 6 can be weakened, and the syringe needle 10 can be more easily removed from the syringe body 9.
