Description

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

Prior 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.

The purpose of this invention is to provide a needle disposal container that allows the needle to be removed from the syringe without directly touching it with the hands, and also allows the needle to be disposed of into the disposal container.

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 on the top wall, and a syringe needle insertion hole on the periphery of the syringe needle insertion hole on the top wall. A flexible needle gripping member extending upwardly and outwardly is provided in an upwardly projecting manner, and the needle gripping member is impermeable to blood and drug solution, and
It is made of an elastic sheet that is impenetrable to needles.

In the above, the needle disposal container may be integrally molded as a whole, the top wall and the peripheral wall may be molded separately and joined together, or the top wall may have a needle insertion hole. Alternatively, a large opening may be formed and this opening may be closed with a closure body having an injection needle insertion hole.

Further, the needle gripping member is made of a rubber sheet or a plastic sheet. Further, the needle gripping member may be provided integrally with the top wall, or may be provided separately and fixed.

Further, it is preferable that a removable cap is provided on the top wall of the needle disposal container so as to cover the entire needle gripping member.

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 syringe needle is inserted into the container through the syringe needle insertion hole until the tip of the needle tube enters the container, and then the base of the syringe needle is gripped via the syringe needle gripping member. Then, pull the needle base downward or pull the syringe barrel upward to remove the syringe needle from the tip of the syringe barrel. after that,
When the hand is released, the injection needle passes through the injection needle insertion hole and is accommodated in the container. On the other hand, the gripping member returns to its original shape due to its own elasticity. In this way, the syringe needle is removed from the syringe barrel. When the container is full of used needles, discard the entire container.

Further, in the case of the paper body 3, it is preferable that at least the inner circumferential surface of the entire body 3 is subjected to surface treatment using a material such as paraffin or wax that does not allow blood, chemicals, etc. to pass through.

The composite material body 3 mainly made of paper includes a paper core, a lining that covers the entire inner peripheral surface of the core and is bonded to the core with adhesive, and an outer peripheral surface of the core. The one that covers the entire core and consists of an outer layer bonded to the outer peripheral surface of the core with an 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 used on the inner surface of the body 3. 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 3 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 3.

The body 3 made of a composite material mainly made of plastic is, for example, one in which the inner surface of a strong plastic layer is covered with an aluminum layer, and the inner surface is further covered with a synthetic resin layer, but the present invention is not limited to such a structure. . The aluminum layer is formed by laminating an aluminum foil or sheet to a plastic layer or by vapor depositing aluminum onto a plastic layer. The plastic used is, for example, a polyolefin thermoplastic synthetic resin such as polypropylene, polyethylene, or polyethylene terephthalate.
