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;

an input device configured to receive a first information on a medical waste item;

said input device configured to query the user for a second information as to whether the waste item is a sharps item;

a control system configured to classify said waste item based on said first and second information;

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

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

wherein the control system is further configured to allow the movable lid of the identified removable container to move to the open position to receive a medical waste item.

2. The system of claim 1, wherein said input device comprises a pharmaceutical waste identification device.

3. The system of claim 1, wherein said input device further queries the user for a third information as to whether the waste item is empty or not empty.

4. The system of claim 1, wherein the input device comprises a handheld device.

5. The system of claim 1, wherein the input device comprises a wireless device.

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

7. The system of claim 1, wherein the input device communicates the received first and second information to the control system.

8. The system of claim 1, wherein the input device comprises a display.

9. The system of claim 1, wherein the input device communicates said first information to the control system.

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

11. The system of claim 9, wherein said first information comprises information regarding whether or not the waste can be directly discharged into a particular sewer system.

12. The system of claim 1, wherein the medical waste comprises pharmaceutical waste.

13. The system of claim 1, wherein the control system classifies said waste item using waste item classification information based on environmental or drug enforcement regulations.

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

15. The system of claim 14, wherein said manual input system is configured to simultaneously query the user for said first information and for information regarding whether or not the waste item is empty.

16. The system of claim 1, wherein at least one of the lids is configured for manual closure by the user.

17. The system of claim 1, wherein at least one of said lids is configured for automatic closure upon disposal of the waste item.

18. The system of claim 1, further comprising:

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

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

20. The system of claim 1, wherein at least one of the 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.

21. The system of claim 20, wherein access is restricted while the container is open and still capable of receiving waste.

22. The system of claim 1,

wherein said movable lid is configured to lock in a covered position when the removable container associated with said lid is full.

23. The system of claim 1, wherein said movable lid is configured to lock in a closed position after receipt of the waste item into the container associated with the lid.

24. The system of claim 1, wherein the control system is further configured to allow the movable lid of the identified removable container to move to the closed position.

25. The system of claim 1, wherein at least one of the containers is disposable.

26. The system of claim 1, wherein at least one of the containers is reusable.

27. 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.

28. 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.
