Abstract

The system (10) for collecting and disposing of medical sharps and other medical wastes includes a housing (11) and its telescopic cover (9) which are fabricated of biodegradable and combustible material such as natural cellulose, non-natural cellulose, and other materials and an absorbent biodegradable and combustible absorption package (30) or insert (35) can be placed in the bottom of the holding chamber (12) for absorbing any liquids emitted from the sharps and other medical wastes, and for enhancing the combustion of the medical sharps and other medical wastes when the housing is placed in a furnace. The system for collecting and disposing of medical wastes when burned, evolves no more than trace levels of sulfur or chlorine and yields substantially only biodegradable ash.

Claims

3. The collector of claim 1 and wherein the housing is sufficiently rigid to hold its shape during initial combustion of the housing so as to retain the medical sharps in the holding chamber during initial combustion of the medical sharps.

4. The collector of claim 1 and wherein said material is liquid-absorptive so as to absorb any liquids that may be emitted from or residing on the medical wastes deposited in the holding chamber.

5. The collector of claim 1 and wherein the housing is sufficiently leak-resistant so as to safely contain the medical wastes, including liquid medical wastes which are deposited in the holding chamber.

6. The collector of claim 1 and wherein the housing is sufficiently puncture-resistant to accommodate the needs of different locations throughout the medical facility, and provide a safe medical environment for collecting and disposing of medical wastes.

7. The collector of claim 1 and further comprising a wall bracket including a support, ring, and wherein said collector housing is sized and shaped to be received in and supported by said support ring.

8. The disposable collector of claim 1 and wherein said housing is cylindrical and comprises a cylindrical side wall turned in at its ends to form inwardly projecting seats, and end walls at opposite ends of said housing supported by said seats.

9. The disposable collector of claim 8 and wherein said opening is formed in one of said end walls.

10. The disposable collector of claim 8 and wherein one of said end walls is scored to form weakened lines of separation, for permitting the medical wastes to open the scored portion of the end wall and be deposited inside the housing.

11. The disposable collector of claim 8 and wherein said housing comprises a telescopic housing structure, including a body and a telescoping cover mounted about said body, with the telescoping cover connected to said body.

12. The disposable collector of claim 1 and wherein said housing comprises two telescoping portions and an connection between said two telescoping portions.

13. The disposable collector of claim 12 and wherein the connection is made with adhesives which when burned emit no more than trace levels of chlorine or sulphur.

14. The disposable collector of claim 1 and further including a head with downwardly facing opening and a downwardly extending collar with a curved chute extending between said opening and said collar, said collar including support means for supporting the housing with the aperture of said housing mounted about said collar.

15. The disposable collector of claim 14 and wherein said collar of said head comprises studs which function as a connector and support means for mounting said collector to the head.

16. The disposable collector of claim 1 and wherein said housing is colored with coloring agents which are biodegradable.

17. The disposable collector of claim 1 and wherein said housing comprises a combination of tubes made of natural cellulosic material such as cardboard, fiberboard, particle board, paper stock, and wood, non-natural cellulosic materials such as rayon, cellophane, and cellulose-nitrate, and other materials such as natural rubber and natural wax which are combustible and biodegradable.

18. The disposable collector of claim 1 and wherein said housing material includes at least one of anti-microbial, anti-fungal, or anti-bacterial additives.

19. A disposable collector for medical wastes including medical sharps and other forms of medical wastes including chemotherapy wastes which require controlled incineration, comprising:

a body defining a holding chamber formed of puncture and leak resistant, absorptive and combustible material, for absorbing fluids emitted from wastes placed in said body and for controlling combustion of said wastes, said combustible material being selected from a group of materials consisting of;

natural cellulosic materials such as paper stock, cardboard, fiberboard, particle board, wood, and molded cellulose, non-natural cellulosic materials such as rayon, cellophane, and cellulose-nitrate, and other materials such as natural rubber and natural wax.

20. A disposable collector for receiving and disposing of medical wastes, including medical sharps and chemotherapy wastes, which require controlled incineration comprising:

a housing defining a holding chamber and an opening in communication with said holding chamber for the receipt of medical wastes,
