Abstract

An hygienically disposable needle and syringe destructor unit is designed for receiving and destroying used needles and syringes and retaining them within a hermetically sealed enclosure. The needle and syringe are broken in three parts to ensure non-use and are trapped within a fluid impervious container. A viewing window allows the operator to ascertain when the container is full and a sealable cover hermetically seals the needle and syringe access aperture so that the unit can be disposed of without fear of damage to the environment.

Claims

1. Apparatus for destroying needles and syringes comprising:

container means including an opening at a top part thereof receiving a piston;

handle means arranged on said top part and connected with said piston for driving said piston between first and second positions within said container;

support means within said container adapted for receiving a needle and syringe, said support being arranged under said piston such that said needle or syringe becomes crushed when said piston forces said needle and syringe into contact with said support; and

aperture means formed within a side of said container providing entry for said needle and syringe, said aperture including closure means whereby said aperture means becomes hermetically sealed for environmentally safe disposal of said container.

2. The apparatus of claim 1 including sealant means arranged around a part of said piston means intermediate said piston and said opening thereby allowing said piston to move between said first and second positions without allowing transfer of fluids in or out of said container.

3. The apparatus of claim 2 wherein said closure means comprises an aperture cover arranged for fastening to said container over said aperture to provide a hermetic seal to said aperture and thereby prevent transfer of said fluids in or out of said container.

4. The apparatus of claim 3 including sealant means arranged on said apertures cover intermediate said aperture cover and said aperture.

5. The apparatus of claim 1 wherein said handle is pivotally attached to said top part.

6. The apparatus of claim 5 including a spring associated with said piston to thereby bias said piston to said first position.

7. The apparatus of claim 5 wherein said top part comprises a container cover.

8. The apparatus of claim 7 wherein said container cover is attached to said container by welding.

9. The apparatus of claim 1 further including flexible means holding said aperture cover to said container.

10. The apparatus of claim 9 wherein said flexible means comprises a chain.

11. The apparatus of claim 7 wherein said support comprises a V-shaped configuration.

12. The apparatus of claim 11 wherein said piston includes a punch attached to one end.

13. The apparatus of claim 1 including a viewing window on one side of said container providing inside visual to said container.

14. The apparatus of claim 1 including guide means associated with said support to hold said needle and syringe until said punch crushes said needle and syringe against said support and thereafter allowing said crushed needle and syringe to drop into said container.

15. The apparatus of claim 14 wherein said guide means in spring-loaded to a closed position.

16. The apparatus of claim 15 wherein said support comprises a pair of sides arranged in a V-shaped configuration.
