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 system for sorting a plurality of medical waste items, the system comprising:

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

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

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;

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

a control system configured to compare information obtained from the handheld waste item identification device with medical waste item classification information contained in a database;

wherein the control system is further configured to assign the item to at least one medical waste category; and

wherein the control system is further configured to identify one of the removable containers based on the medical waste category;

wherein the control system is further configured to allow the movable lid of the identified removable container to move to the open position to permit disposal of said medical waste item; and

wherein the control system is further configured to lock the movable lid in a closed position after receipt of a medical waste item.

2. The system of claim 1, wherein the control system is configured to lock the movable lid in a closed position after the container associated with said lid has reached a pre-set fill level.

3. The system of claim 1, further comprising a barcode scanner located on or coupled with a sorting station that houses the plurality of container compartments.

4. The system of claim 1, wherein the handheld waste item identification device is wireless.

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

6. The system of claim 1, wherein the handheld waste item identification device comprises a scanner that scans said medical waste item and communicates said scanned information to said control system.

7. The system of claim 1, wherein said handheld waste item identification comprises a display.

8. The system of claim 1, wherein said handheld waste item identification device displays information regarding the waste item being discarded.

9. The system of claim 8, wherein said information comprises information regarding the particular waste container in which the waste item should be placed.

10. The system of claim 1, wherein said medical waste comprises pharmaceutical waste.

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

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

13. The system of claim 12, wherein said handheld waste item identification device comprises a manual input system that queries the user for information as to whether the waste item is a sharps or whether the waste item is empty.

14. The system of claim 1, wherein at least one of said containers comprises at least one of said moveable lids that is operable to be manually closed by a user.

15. The system of claim 1, wherein at least one of said containers comprises at least one of said moveable lids that is operable to be automatically closed or locked upon disposal of the waste item.

16. The system of claim 1, further comprising:

a sensor that senses disposal of said waste item into at least one of said containers,

wherein at least one of said containers comprises a lid that automatically closes or locks upon receiving information based on said sensor.

17. The system of claim 1, wherein at least one of said containers comprises a machine-readable identification key enabling said container to be hot-swapped.

18. The system of claim 1, wherein at least one of said containers prevents unauthorized personnel from accessing the waste item once the item has been deposited into said container, thereby restricting access to the internal contents of that container.

19. The system of claim 18, wherein access is restricted while the container is open and still capable of receiving waste.

20. The system of claim 1, wherein at least one of said containers is reusable.

21. The system of claim 1, wherein at least one of said containers is disposable.

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

23. The system of claim 1, wherein the control system is configured to automatically determine the waste category associated with at least one of said containers after said container is placed into said container compartment.

24. The system of claim 1, wherein the control system is configured 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.

25. The system of claim 1, wherein said database comprises rules and regulations governing the disposal of pharmaceutical waste.
