Abstract

A system for disposing of medical waste is generally configured to sort waste items into a plurality of containers according to applicable rules and regulations governing the handling and/or disposal of such items. In one embodiment, at least one of the medical waste items is a regulated drug that is regulated by, for example, the Drug Enforcement Administration (DEA). The regulated drug is inaccessible once disposed in the container. In some embodiments, a system comprises sorting stations each of which houses a number of disposable containers. Each station can identify an item of waste, determine the most appropriate container for the item, and facilitate disposal of the item in the appropriate container. In some embodiments, a detection system for determining a presence and/or a quantity of waste items within a container is also provided. In some embodiments, access to discarded waste items is restricted once the waste items have been placed in a container.

Claims

1. A method for sorting waste items using a restricted access disposable container system for medical waste items, the method comprising:

providing at least one medical waste sorting system, wherein said medical waste sorting system comprises a plurality of container compartments, each container compartment configured to receive a removable container;

providing a plurality of removable containers, wherein the removable containers are configured to be placed within the container compartments;

wherein each of the plurality of removable containers is sized to have an internal volume of about 1 gallon to about 20 gallons;

wherein each of the removable containers is associated with at least one of a plurality of waste categories;

wherein at least one of the removable containers comprises a radio frequency identification (RFID) tag;

wherein at least one of the container compartments comprises a radio frequency (RFID) reader;

wherein the RFID reader is configured to read the RFID tag to determine a container position within the waste sorting system or the waste category of the container;

providing a scanner configured to determine a barcode of a waste item;

wherein the waste item is a regulated drug;

providing a control system that compares information obtained from the barcode with waste item classification information;

assigning the waste item to at least one waste category;

identifying one of the removable containers based on the waste category;

sorting said waste by automatically opening the identified removable container to move to the open position to permit disposal of said regulated drug;

wherein the identified removable container is disposable;

rendering the regulated drug inaccessible once said regulated drug has been disposed in the identified removable container; and

locking said identified removable container in a closed position.

2. The method of claim 1, further comprising alerting a user after said identified removable container has reached a pre-set fill level.

3. The method of claim 1, wherein the scanner comprises a handheld barcode scanner.

4. The method of claim 1, further comprising communicating information from the scanner to said control system.

5. The method of claim 1, further comprising wirelessly communicating information from the scanner to said control system.

6. The method of claim 1, further comprising displaying information regarding the waste item being discarded.

7. The method of claim 1, further comprising providing a manual input system for manually entering information regarding the waste item.

8. The method of claim 1, wherein the RFID tag further comprises information describing the contents of the container comprising said tag.

9. The method of claim 1, wherein at least one of the removable containers comprises a container label in addition to the RFID tag.

10. The method of claim 1, further comprising printing a manifest based at least in part on data obtained from the RFID tag.

11. The method of claim 1, further comprising generating a manifest identifying the contents disposed in the identified removable container.

12. The method of claim 1, wherein the classification information is contained in a database.

13. A method for sorting waste items using a restricted access disposable container system for medical waste items, the method comprising:

providing at least one medical waste sorting system sized to fit in a single room, wherein said medical waste sorting system comprises a plurality of container compartments, each container compartment configured to receive a removable container;

providing a plurality of removable containers, wherein the removable containers are configured to be placed within the container compartments;

wherein each of the plurality of removable containers is sized to have an internal volume of about 1 gallon to about 20 gallons;

wherein each of the removable containers is associated with at least one of a plurality of waste categories;

wherein at least one of the removable containers comprises a machine readable identification key;

reading said machine readable identification key to determine a container position within the waste sorting system or the waste category of the container;

providing a scanner configured to determine a barcode of a waste item;

wherein the waste item is a regulated drug;

providing a control system that compares information obtained from the barcode with waste item classification information;

assigning the waste item to at least one waste category;

identifying one of the removable containers based on the waste category;

sorting said waste by automatically opening the identified removable container to move to the open position to permit disposal of said regulated drug;

wherein the identified removable container is disposable;

rendering the regulated drug inaccessible once said regulated drug has been disposed in the identified removable container; and

locking said identified removable container in a closed position.

14. The method of claim 13, further comprising alerting a user after said identified removable container has reached a pre-set fill level.

15. The method of claim 13, wherein the scanner comprises a handheld barcode scanner.

16. The method of claim 13, further comprising communicating information from the scanner to said control system.

17. The method of claim 13, further comprising wirelessly communicating information from the scanner to said control system.

18. The method of claim 13, further comprising displaying information regarding the waste item being discarded.

19. The method of claim 13, further comprising providing a manual input system for manually entering information regarding the waste item.

20. The method of claim 13, wherein the machine readable identification key further comprises information describing the contents of the container comprising said key.

21. The method of claim 13, wherein at least one of the removable containers comprises a container label in addition to the machine readable identification key.

22. The method of claim 13, further comprising printing a manifest based at least in part on data obtained from the machine readable identification key.

23. The method of claim 13, further comprising generating a manifest identifying the contents disposed in the identified removable container.

24. The method of claim 13, wherein the classification information is contained in a database.
