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 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 a plurality of medical waste items, the method comprising:

providing a plurality of container compartments, each container compartment configured to receive a removable container;

providing a plurality of removable containers, wherein each of said removable containers comprises an opening;

providing a movable lid coupled with each of said removable containers;

wherein the removable containers are configured to be placed within the container compartments,

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

wherein the movable lid is movable to an open position; and

wherein the movable lid is movable to a closed position;

providing a handheld waste item identification device configured to determine a information on a medical waste item;

providing a control system that compares information obtained from the handheld waste item identification device with medical waste item classification information contained in a database;

assigning the waste item to at least one medical waste category; and

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

allowing the movable lid of the identified removable container to move to the open position to permit disposal of said medical waste item; and

locking the movable lid after receipt of a medical waste item.

2. The method of claim 1, further comprising locking the movable lid after the container coupled with said lid has reached a pre-set fill level.

3. The method of claim 1, wherein the handheld waste item identification device comprises a barcode scanner that scans said medical waste item.

4. The method of claim 1, further comprising communicating information from the handheld waste item identification device to said control system.

5. The method of claim 1, further comprising wirelessly communicating information from the handheld waste item identification device to said control system.

6. The method of claim 1, wherein said handheld waste item identification comprises a display.

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

8. The method of claim 1, wherein said waste item classification information comprises classification information based on environmental or drug enforcement regulations.

9. The method of claim 1, wherein said handheld waste item identification device comprises a manual input system for manually entering information regarding the waste item.

10. The method of claim 9, wherein said handheld waste item identification device comprises a manual input system that queries a user for information as to whether the waste item is a sharps or whether the waste item is empty.

11. The method of claim 1, wherein at least one of said moveable lids is configured to be manually closed.

12. The method of claim 1, wherein at least one of said moveable lids is configured to be automatically closed or locked upon disposal of the waste item.

13. The method of claim 1, further comprising:

sensing disposal of said waste item into at least one of said containers,

automatically closing or locking the lid associated with said container upon receiving information based on said sensor.

14. The method of claim 1, further comprising providing at least one said containers with a machine-readable identification key, thereby enabling said container to be hot-swapped.

15. The method of claim 1, further comprising restricting access to the internal contents of at least of said container while said container is open and still capable of receiving waste.

16. The method of claim 1, wherein at least one of said containers is reusable.

17. The method of claim 1, wherein at least one of said containers is configured to contain sharps.

18. The method of claim 1, further comprising configuring said control system to automatically determine the waste category associated with at least one of said containers after said container is placed into said container compartment.

19. The method of claim 1, further comprising configuring said control system to automatically determine the waste category associated with at least one of said containers based on a machine readable key that is located on said container.

20. The method of claim 1, further comprising providing said database, wherein said database comprises rules and regulations governing the disposal of pharmaceutical waste.
