Abstract

A system for disposing of medical waste is generally configured to sort waste items into a plurality of disposable 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.

Claims

1. A waste 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 associated 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 waste item identification device configured to receive information regarding a medical waste item;

a control system configured to assign the medical waste item to a medical waste category, wherein said assignment is based on the information obtained from the waste item identification device and medical waste item classification information;

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

wherein the control system is further configured to allow the movable lid associated with the identified removable container to move to the open position; and

at least one of said removable containers comprising at least one of a color or a pattern;

and wherein the control system is configured to automatically determine the waste category associated with the container based on said color or pattern.

2. The system of claim 1, wherein the color comprises a plurality of colors.

3. The system of claim 1, wherein said pattern comprises an optically-readable marking.

4. The system of claim 1, wherein said pattern comprises a pattern of holes.

5. The system of claim 1, wherein said pattern comprises alphanumeric characters.

6. The system of claim 1, wherein said pattern comprises a graphical pattern.

7. The system of claim 1, wherein said pattern is magnetically readable.

8. The system of claim 1, wherein the waste category defines a class of waste to be placed in the container.

9. The system of claim 1, wherein the waste category of a container is independent of the container compartment in which the container is positioned.

10. The system of claim 1, wherein said moveable lid is removable.

11. The system of claim 1, wherein said moveable lid is associated with said container via a coupling mechanism.

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

13. The system of claim 1, wherein at least one of the containers is reusuable.

14. The system of claim 1, wherein the waste identification device comprises a barcode scanner.

15. The system of claim 1, wherein the waste identification device comprises a manual input device, wherein said manual input device is operable to receive information manually entered by a user.

16. The system of claim 15, wherein said manual input device comprises at least one of a touch screen or keyboard.

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

18. The system of claim 1, wherein the control system is configured to automatically determine the waste category associated with the container after said color or pattern is detected by a container reader.

19. The system of claim 1, wherein the control system is configured to automatically determine the waste category associated with the container after said color or pattern is optically scanned by a container reader.

20. The system of claim 1, further comprising a key reader that reads said color or said pattern.

21. The system of claim 1, wherein said color or said pattern is a machine readable key that is readable by a key reader located within at least one of the container compartments.

22. The system of claim 1, further comprising a sensor configured to detect the level of waste within at least one of said containers.

23. The system of claim 1, wherein the movable lid is configured to lock after the waste system determines that the container associated with said lid has reached a pre-set fill level.
