Description

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

BACKGROUND ART Conventionally, used injection needles were manually removed from syringes and disposed of in a special disposal container for injection needles.

Problems that the invention aims to solve: However, if the blood adhering to the needle contains pathogens such as hepatitis B or AIDS, if the tip of the needle accidentally pierces the skin when removing the needle and disposing of it in a container. In addition, there was a risk that pathogens such as hepatitis B and AIDS in the blood adhering to the needles could enter the body and cause infection with these diseases.

In addition, if blood or drug solution adhering to the needle accumulates at the bottom of the waste container and the waste container is accidentally knocked over,
There is a risk that the blood and the like may leak from the needle insertion port.
If the blood contains pathogens such as hepatitis B and AIDS, if the spilled blood is disposed of with an injured hand, the pathogens such as hepatitis B and AIDS in the blood will enter the body through the wound. There was a risk of being infected with these diseases.

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

Means for Solving the Problem The syringe needle disposal container according to this invention has a cylindrical body made of paper or a composite material mainly made of paper, and is fixed to the lower end of the body by double wrapping to close the opening at the lower end of the body. A bottomed cylindrical container body consisting of a metal bottom lid, which is fixed to the top end of the body by double wrapping to close the top opening of the body, and a liquid absorption/retention container placed on the bottom lid. It is equipped with wood, and on the top cover,
A needle insertion hole larger than the outer diameter of the needle base of the injection needle is formed, and a needle insertion hole larger than the outer diameter of the tip of the syringe barrel to which the injection needle is attached is formed on the periphery of the injection needle insertion hole, and larger than the outer diameter of the needle base. A U-shaped concave portion with a small width is formed, and the peripheral edge of the liquid absorbing and retaining material is bent upward and brought into close contact with the inner circumferential surface of the body, and the liquid absorbing and retaining material connects the body and the bottom lid. This means that the parts are not in contact with each other.

In the above, the liquid absorbing and retaining material used is a porous body that takes in and retains blood, medical solutions, etc. through physical action, or a polymeric absorber that takes in and retains blood, medical fluid, etc. through chemical action. It will be done.

In the above, the paper cylinder used is one made of strong single-layer cardboard, one made of two or more layers of cardboard, or the like. As the cardboard, it is preferable to use paperboard, paper tube base paper, or the like. In the case of a paper barrel, at least the inner circumferential surface of the entire barrel is preferably surface-treated using a material such as paraffin or wax that does not allow blood, chemical solutions, etc. to pass through.

A composite material body mainly made of paper has a core made of paper, a lining that covers the entire inner circumferential surface of the core and is bonded to the inner circumferential surface of the core with adhesive, and the entire outer circumferential surface of the core. A material consisting of an outer layer that covers the core and is bonded to the outer peripheral surface of the core with adhesive is used. The core consists of one or more layers of cardboard. As the lining, synthetic resin-coated paper, synthetic resin-coated aluminum (including aluminum alloy; the same shall apply hereinafter) foil or thin plate, water-repellent-impregnated paper, etc. are used. In the case of synthetic resin-coated paper and synthetic resin-coated aluminum foil or thin plate, the synthetic resin coating layer is placed on the inner surface of the body. In the case of synthetic resin-coated aluminum foil or thin plate, it is preferable to previously adhere kraft paper or the like to the outer surface of the body for adhesion to the core. As the outer lining, the same material as the inner lining is used. However, in the case of synthetic resin-coated paper and the same aluminum foil or thin plate, the synthetic resin coating layer is placed on the outer surface of the cylinder.

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, the injection needle is inserted into the container through the injection needle insertion hole until the proximal end of the barrel tip enters the container. Next, the syringe barrel is moved toward the indentation, and after the base end of the barrel tip is placed in the indentation, the syringe barrel is pulled outward. Then, the proximal end of the needle hub catches the part of the top wall and peripheral wall around the indentation in the wall where the injection needle insertion hole and indentation are formed, and when the syringe barrel is pulled further outward, the needle The base is pulled inward and removed from the tube tip. Then, it is housed in a container. Blood or the like adhering to the injection needle housed in the container flows down and is immediately absorbed by the liquid absorbing and holding material, and is held in that state. In addition, the peripheral edge of the liquid absorbing and retaining material is bent upward and brought into close contact with the inner circumferential surface of the body, and the liquid absorbing and retaining material is not in contact with the joint between the body and the bottom cover, so that blood can be absorbed easily. This prevents liquid chemicals and the like from accumulating in the groove formed in the connecting portion between the barrel and the bottom cover. If blood etc. accumulates in the groove,
There is a risk that this blood, etc. may enter the seamed portion and leak to the outside. In addition, if the seaming force is weakened by seeping into the end of the body, and an impact is applied to the seaming part from the outside, the bottom cover may come off and blood, etc. may leak to the outside.

Embodiments This invention will be described below with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, a needle disposal container 1 includes a cylindrical container body 2 with a bottom. The container body 2 has a cylindrical body 15 made of a composite material mainly made of paper.
and a metal bottom cover 3 which is fixed to the lower end of the barrel 15 by double wrapping to close the lower end opening of the barrel 15. The upper end opening of the container body 2 is closed by a metal top cover 4 fixed to the upper end of the body 15 by double seaming. A liquid absorbing and holding material 5 is arranged on the bottom lid 3.

An opening 6 is formed in the top lid 4, and a plastic closure 7 is formed in the top lid 4 to close the opening 6.
is fixed. An inward folded portion 8 is formed in a portion of the top cover 4 around the opening 6. The closure body 7 consists of a cylindrical peripheral wall 9 and a top cover 10.
An annular groove 11 into which the inwardly folded portion 8 of the top cover 4 is fitted is provided on the outer peripheral surface of the peripheral wall 9 over the entire circumference. The closing body 7 is fixed to the top cover 4 by forcibly fitting the peripheral wall 9 of the closing body 7 into the opening 6 and fitting the inner folded portion 8 into the annular groove 11.

The needle base 2 of the injection needle 20 is mounted on the top wall 10 of the closure body 7.
An injection needle insertion hole 12 having a larger outer diameter than the injection needle insertion hole 1 is formed. Further, the peripheral edge of the injection needle insertion hole 12 in the top wall 10 has a width larger than the tip 24 of the outer cylinder 23 of the injection barrel 22 to which the injection needle 20 is attached and smaller than the outer diameter of the needle base 21. A generally U-shaped injection needle removal indentation 13 is formed when viewed from above.

The liquid absorbing and retaining material 5 has a circular shape having a diameter slightly larger than the inner diameter of the barrel 15 when viewed from above, and its peripheral edge is bent so as to be brought into close contact with the inner circumferential surface of the barrel 15 . Furthermore, the liquid absorbing and holding material 5 is designed not to come into contact with the connecting portion between the body 15 and the bottom cover 3.

In such a configuration, in order to remove the injection needle 20 from the tip 24 of the outer barrel 23 of the syringe barrel 22, first insert the needle 20 through the needle insertion hole 12 until the proximal end of the tip 24 enters the container 1. Insert into container 1 (see Figure 3a). Next, the syringe barrel 22 is moved to the indentation part 13 side, and after the base end of the barrel tip 24 is inserted into the indentation part 13 (see FIG. 3b), the syringe barrel 22 is moved to the indentation part 13 side.
pull upward. Then, the top wall 10 of the closure body 7 is caught on the upper end of the needle base 21, and when the syringe barrel 22 is pulled further upward, the needle base 21 is pulled downward and detached from the barrel tip 24, and the liquid absorption and retention material 5 (see Figure 3c). And syringe needle 20
Blood and medicine adhering to the needle tube 25 are absorbed and retained by the liquid absorbing and retaining material 5.

In the above, since the bottom cover 3 is fixed to the lower end of the body 15 by double seaming, the inner surface of the circumferential wall of the concave portion of the bottom cover 3 that has entered the body 15 and the body 1
A groove is formed at the connecting portion with the inner circumferential surface of 5. However, the liquid absorbing and retaining material 5 is formed into a circular shape having a slightly larger diameter than the inner diameter of the body 15 when viewed from above, and its peripheral edge is bent to bring it into close contact with the inner circumferential surface of the body 15. Since the barrel 15 does not come into contact with the connecting portion with the bottom cover 3, blood, liquid medicine, etc. are prevented from accumulating in the groove.
Therefore, blood or the like accumulated in the groove is prevented from entering the seaming portion and leaking to the outside. This also prevents blood, etc. accumulated in the groove from entering the seaming part and soaking into the end of the body, which would weaken the seaming force, thereby preventing external impact from being applied to the seaming part. This prevents blood from leaking outside if the bottom cover comes off.

Effects of the invention According to the syringe needle disposal container 1 of this invention, the container 1
Blood or the like adhering to the discarded injection needle 20 flows down and is immediately absorbed by the liquid absorbing and holding material 5, and is held in that state. Therefore, even if the container 1 is accidentally knocked down, the blood and the like will not leak out of the container 1. Further, the blood and the like are prevented from leaking to the outside through the seamed portion between the body 15 and the bottom cover 3, or from leaking to the outside when the bottom cover 3 comes off. Therefore, when treating blood leaked to the outside, infection with pathogens such as hepatitis B and AIDS contained in the blood is prevented.

Moreover, the bottomed cylindrical container main body 2 includes a cylindrical body 15 made of paper or a composite material mainly composed of paper.
A metal bottom cover 3 is fixed to the lower end of the body 15 by double seaming to close the lower end opening of the body 15, and a metal top lid 3 is fixed to the upper end of the body 15 by double seaming to close the upper end opening of the body 15. Since it consists of the lid 4, the material cost is low.
