Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a container for disposing of used syringe needles.

Problems to be Solved by Conventional Technologies and Ideas Conventionally, used injection needles were removed from syringes by hand and disposed of in a special disposal container for injection needles.

However, if the blood adhering to the needle contains pathogens such as hepatitis B or AIDS, if you accidentally poke your skin with the tip of the needle while removing the needle and discarding it in a container, the blood that has adhered to the needle may be present. There was a risk that pathogens such as hepatitis B and AIDS in the blood could enter the body and become infected with these diseases.

Therefore, in order to solve this problem, a needle insertion hole larger than the outer diameter of the needle base of the injection needle is formed in the top wall of the injection barrel, and the injection needle is attached to the periphery of the injection needle insertion hole. One U-shaped indentation having a width larger than the outer diameter of the barrel tip and smaller than the outer diameter of the needle base is formed on the end face of the injection needle insertion hole and the indentation in the wall where the indentation is formed. Thick-walled parts for needle removal are provided on both sides of the entrance part, and the thickness gradually increases from the needle insertion hole side toward the back of the inlet part, and the minimum wall thickness of the thick-walled parts for needle removal is as follows: A needle disposal container has been considered which is smaller than the distance between the needle base of the injection needle and the end face of the syringe barrel to which the injection needle is attached, and whose maximum wall thickness is also larger than the distance.

However, with this syringe needle disposal container, if the container falls over, blood, etc. that have adhered to the discarded needles and accumulated inside the container may leak out through the syringe needle insertion hole and the indentation. There is a risk of leakage. If the blood contains the above-mentioned pathogens, if the blood spilled from an injured hand is treated,
There was a risk that the above-mentioned pathogens in the blood could enter the body through the wound and cause infection with these diseases. Furthermore, since only one U-shaped indentation is formed at the periphery of the injection needle insertion hole, the direction in which the syringe barrel can be moved is limited when removing the injection needle, making handling inconvenient. .

The purpose of this invention is to provide a needle disposal container that solves the above problems.

Means for Solving the Problems The syringe needle disposal container according to this invention has a syringe needle insertion hole larger than the outer diameter of the needle base of the syringe needle formed in the top wall or the bottom wall, and has a syringe needle insertion hole on the periphery of the syringe needle insertion hole. A U-shaped indentation having a width larger than the outer diameter of the barrel tip provided on the end surface of the syringe barrel to which the injection needle is attached and smaller than the outer diameter of the needle base is formed, and a syringe needle insertion hole and the indentation are formed. On both sides of the indentation in the wall, there are thickened sections for needle removal that gradually become thicker from the needle insertion hole side toward the back of the indentation. A needle disposal container having a minimum wall thickness smaller than the distance between the base of the needle and the end surface of the syringe barrel to which the needle is attached, and a maximum wall thickness larger than the above distance, A recess is formed on the outer surface of the wall or the peripheral wall to project inward, a hypodermic needle insertion hole is formed on the bottom wall of the recess, and a plurality of U-shaped indentations are formed radially around the periphery of the injection needle insertion hole. This is what is being done.

In the above, the syringe needle disposal container may be integrally molded as a whole, the top wall and the bottomed cylindrical peripheral wall may be molded separately and both are fixed together, or the cylindrical peripheral wall and the bottom cylindrical peripheral wall may be molded together. The wall and the bottom wall may be formed separately and then fixed together. In addition, an opening larger than both the injection needle insertion hole and the indentation part is formed in the top wall or the peripheral wall, and this opening is closed with a closure body having both the injection needle insertion hole and the indentation part. But that's fine.

Function To remove a used syringe needle from the tip of the outer barrel of a syringe barrel using the syringe needle disposal container of this invention,
First, insert the syringe needle into the container through the needle insertion hole until the proximal end of the syringe barrel enters the container, and then
Move the syringe barrel toward the indentation and place the proximal end of the barrel tip into the indentation. At this time, first, the minimum thickness portion of the thick-walled portion for removing the syringe needle enters between the proximal end of the base of the syringe needle and the end surface of the syringe barrel. Then, as the syringe barrel is moved toward the inlet, one side of the thick-walled part for syringe needle removal is attached to one of the end face of the syringe barrel and the proximal end of the needle hub, and the other side is attached to the above end face of the syringe barrel. It abuts either the end surface or the proximal end of the needle hub, respectively. When the syringe barrel is further moved, the thick portion applies a force to the needle base that pulls it inward into the container, and this force causes the needle base to detach from the barrel tip.
Then, it is housed in a container. In this way, the syringe needle is removed from the syringe barrel. When the container is full of used needles, discard the entire container.

A plurality of U-shaped indentations are formed radially around the periphery of the injection needle insertion hole, so insert the injection needle into the container through the injection needle insertion hole until the base end of the tip of the syringe barrel enters the container. After that, the needle can be removed from the syringe by moving the syringe to either side of the inlet.

Furthermore, since a recess is formed on the outer surface of the top wall or the peripheral wall to project inward, and a needle insertion hole is formed on the bottom wall of the recess, even if the container falls over,
Blood and the like accumulated in the container can be prevented from leaking to the outside.

Embodiments Hereinafter, embodiments of this invention will be described with reference to the drawings.

In FIGS. 1 and 2, the needle disposal container 41 has a bottomed cylindrical container body 32 integrally formed from metal, plastic, etc., and is bonded and fixed to the upper end of the container body 32 to close the upper end opening. It consists of a top cover 33 (top wall) made of metal or plastic. A circular recess 34 is provided in the center of the top cover 33 and projects downward, which is concentric with the periphery of the top cover 33 when viewed from above. Then, on the bottom wall 32a of the container body 32, a porous body that takes in and holds blood, liquid medicine, etc. through a physical action, or a polymer absorbent body that takes in and holds blood, liquid medicine, etc. through a chemical action, etc. A liquid absorbing and holding material 6 consisting of the following is disposed.

In the bottom wall 34a of the recess 34, an injection needle insertion hole 13 having a larger outer diameter than the needle base 21 of the injection needle 20 is formed. Further, the periphery of the injection needle insertion hole 13 in the bottom wall 34a of the recess 34 has a diameter larger than the outer diameter of the tip 24 of the outer cylinder 23 of the syringe barrel 22 to which the injection needle 20 is attached, and the outer diameter of the needle base 21. A plurality of indented portions 14, which are approximately U-shaped when viewed from a plane and have a width smaller than the diameter, are formed radially at intervals in the circumferential direction. In addition, the bottom wall 34 of the recess 34
By providing inclined walls 15 whose tips are inclined downward from the needle insertion hole 13 side toward the back of the indentation part 14 on both sides of each indentation part 14 on the lower surface of a, the thickness for removing the injection needle is increased. A flesh portion 16 is formed. The minimum thickness of the thick-walled portion 16 for removing the injection needle is smaller than the distance between the needle base 21 of the injection needle 20 and the end surface of the injection barrel 22 to which the injection needle 20 is attached,
Similarly, the maximum wall thickness is made larger than the above distance.

The liquid absorbing and holding material 6 has a circular shape having a diameter slightly larger than the inner diameter of the body 3 when viewed from above, and its periphery is bent so as to be brought into close contact with the inner circumferential surface of the body 3.

Next, a method for removing the injection needle 20 from the tip 24 of the outer cylinder 23 of the injection barrel 22 will be explained with reference to FIG. 3. First, insert the injection needle 20 into the container 41 through the injection needle insertion hole 13 until the proximal end of the barrel tip 24, that is, the unfitted part of the needle base 21, enters the container 41 (see FIG. 3a). . Then,
The syringe barrel 22 is moved to one of the indentations 14, and the proximal end of the barrel tip 24 is inserted into the indentation 14 (see FIG. 3b). At this time, first, the minimum thickness portion of the thick-walled portion 16 for removing the injection needle enters between the proximal end of the needle base 21 of the injection needle 20 and the end surface of the injection barrel 22. Then, as the syringe barrel 22 is moved toward the inlet part 14 side, the tip of the inclined wall 15, that is, the inner surface of the thick walled part 16 for removing the syringe needle on the top wall 11 is brought into contact with the needle base 21.
At the proximal end of the top wall 11, the outer surface of the thick-walled portion 16 for removing the syringe needle abuts the end surface of the syringe barrel 22, respectively. When the syringe barrel 22 is further moved, a force is applied to the needle base 21 that pulls it inward to the container 41, and this force causes the needle base 21 to come off the barrel tip 24 and be accommodated in the container 41. In this way, the injection needle 20 is removed from the injection barrel 22. When the container 41 is full of used injection needles 20, the container 41 is discarded. Blood and medicine adhering to the needle tube 25 of the injection needle 20 are absorbed and retained by the liquid absorbing and retaining material 6.

In the above embodiment, the recess, the injection needle insertion hole,
Although the indentation part and the injection needle removal wall are formed on the top wall of the injection needle disposal container, they are not limited thereto, and may be formed on the peripheral wall.

Effects of the Invention According to the syringe needle disposal container of this invention, as described above, the syringe needle can be removed from the syringe barrel without being touched by hand, and can be disposed of in the disposal container. Therefore, when removing a used syringe needle and disposing of it in a container, the tip of the needle does not accidentally poke the skin, and the hepatitis B in the blood that was attached to the needle can be removed.
There is no risk of pathogens such as AIDS entering the body and infecting these diseases.

In addition, since a plurality of U-shaped indentations are formed radially around the periphery of the injection needle insertion hole, the injection needle can be inserted easily.
After inserting the syringe barrel into the container through the needle insertion hole until the proximal end of the tip of the syringe barrel enters the container, the needle can be removed from the syringe barrel by moving the syringe barrel to either side of the inlet. Therefore, it is easy to handle.

Furthermore, a recess is formed on the outer surface of the top wall or the peripheral wall to project inward, and a needle insertion hole and an indentation are formed on the bottom wall of the recess, so even if the container falls over, the container It is possible to prevent blood, etc. that has been accumulated inside from leaking to the outside. Therefore, infection with pathogens in the blood is prevented when blood leaked to the outside is treated.
