Abstract

Disclosed and claimed herein are devices for the treatment of medical waste using high temperature and pressure steam. The devices are designed to be self-contained and are movable by one person of average strength and ability. The devices are self-contained and require no special installation, connections, plumbing or permanent or semi-permanent electrical connections. Disclosed and claimed herein are methods using the disclosed and claimed devices.

Claims (36)

1. A self-contained medical waste sterilization and processing device comprising a housing comprising:

a. at least one ingress connected to a first sealable compartment, optionally comprising a compaction device, capable of receiving steam and maintaining elevated steam pressure,

b. a steam generating component connected to the first sealable compartment for supplying steam at elevated pressures to the compartment,

c. a grinder component situated after the first compartment,

d. a second compartment configured to receive steam-treated medical waste from the first compartment, to package the waste and to seal the package containing the waste for removal from an egress in the housing, and

e. a water reclamation component configured to remove excessive water from the first sealable compartment and return it to the steam generating component,

wherein the steam generating component is self-contained and free of external connections to a water supply, and wherein the package is optionally vacuum heat sealed.

2. The device of claim 1 , wherein the steam generating component comprises a steam generator and a water reservoir, and optionally a steam reservoir, wherein the water reservoir is configured to supply water to the steam generator and receive water from the water reclamation component.

3. The device of claim 2 , wherein the device operates using standard electrical power as supplied by a wall outlet.

4. The device of claim 2 , wherein the device is free of attachments requiring installation.

5. The device of claim 4 , wherein the device is portable.

6. The device of claim 5 , further comprising a programmable logic system for user identification and analyzing the time of treatment, the steam temperature and the steam pressure for treatment of the medical waste and relaying the data to device controls and log files.

7. The device of claim 6 , further comprising at least one RFID identification, bar code, or identifying indicia or tracking device provided with the package.

8. The device of claim 7 , further comprising a radiation detection system.

9. The device of claim 8 , further comprising a system for cleansing the first sealable compartment.

10. The device of claim 8 , further comprising a quality control system interfaced with the programmable logic system to ensure proper operating parameters.

11. A method of treating medical waste comprising the steps of obtaining the device of claim 1 , and

a. introducing the medical waste to the first sealable compartment via the inlet,

b. treating the medical waste by exposing the waste to high temperature steam and pressure from the steam generating component at least about 3 minutes,

c. optionally compacting the waste,

d. treating the medical waste by exposing the waste to high temperature steam and pressure from the steam generating component a second time for at least about 3 minutes,

e. removing a substantial amount of moisture from the treated waste and returning it to the steam generation system,

f. grinding or shredding the treated waste,

g. moving the treated waste to a heat sealable bag in a the second compartment,

h. optionally substantially removing air from the bag,

i. sealing the bag, and

j. removing the sealed bag from the device.

12. The method of claim 11 , wherein the steam generating component comprises a steam generator and a water reservoir, and optionally a steam reservoir, wherein the water reservoir is configured to supply water to the steam generator and receive water from the water reclamation component.

13. The method of claim 12 , wherein the device operates using standard electrical power as supplied by a wall outlet.

14. The method of claim 13 , wherein the device is free of attachments requiring installation.

15. The method of claim 14 , wherein the device is portable.

16. The method of claim 15 , wherein the device further comprising a programmable logic system for user identification and analyzing the time of treatment, the steam temperature and the steam pressure for treatment of the medical waste and relaying the data to device controls and log files and the method further comprises the steps of entering a user code, analyzing the time of treatment, the steam temperature and the steam pressure for treatment of the medical waste and relaying the data to device controls and log files.

17. The method of claim 16 , wherein the programmable logic system provides identification for the sealed bag, RFID tags, bar codes, or indicia.

18. The method of claim 15 , wherein the device further comprises a radiation detection system and the method further comprises the step of determining radiation in the medical waste prior to sterilization.

19. The method of claim 15 , further comprising the step of cleansing the first sealable compartment after the treated waste is removed.

20. The method of claim 15 , wherein the device further comprises a quality control system interfaced with the programmable logic system to ensure proper operating parameters.
