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 method for sorting and tracking a drug before and after administration to a patient, the method comprising:

providing a medical waste sorting system comprising a plurality of waste container compartments for housing a plurality of removable waste containers,

wherein each of said removable waste containers comprises an opening and a machine readable identification key;

providing an automatically movable lid coupled with each of said removable waste containers;

wherein each of the removable waste containers is associated with at least one of a plurality of waste categories, wherein the movable lid is movable to an open position and a closed position;

reading said machine readable identification key to determine the waste category associated with the container via a key reader;

obtaining information regarding a drug to be administered to a patient, wherein said information comprises the quantity of said drug in a drug container prior to administration of said drug to said patient;

obtaining scanned barcode information from a spent drug container via a barcode reader,

wherein the spent drug container comprises the drug container and a spent drug, wherein the spent drug is the drug that still remains in the drug container after said drug has been at least partially administered to a patient;

electronically accessing a database comprising waste item classification information;

electronically assigning the spent drug container to at least one waste category based at least in part on the scanned barcode information and said waste item classification information;

automatically opening the lid coupled to the removable container associated with said waste category to permit disposal of the spent drug container;

automatically locking the lid coupled to the removable container in the closed position after disposal of the spent drug container;

prompting a user to enter information regarding the quantity of the spent drug; and

electronically comparing the quantity of the spent drug with the quantity of the drug prior to administration to said patient, thereby tracking the drug before and after administration to the patient.

2. The method of claim 1, further comprising calculating the quantity of the drug that should have been administered to the patient by comparing the quantity of the spent drug with the quantity of the dispensed drug.

3. The method of claim 1, further comprising reporting to a user the quantity of the drug that should have been administered to the patient.

4. The method of claim 1, further comprising comparing the quantity of the drug that should have been administered to the patient to a quantity that was actually administered to the patient.

5. The method of claim 1, further comprising generating a manifest containing information regarding the quantity of the spent drug.

6. The method of claim 1, wherein said waste item classification information comprises classification information based on environmental or drug enforcement regulations contained in a database.

7. The method of claim 1, wherein obtaining scanned barcode information from the spent drug container comprises scanning a barcode label located on the spent drug container.

8. The method of claim 1, wherein the container containing said spent drug comprises a bottle, a syringe, or an intravenous (IV) bag.

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

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

11. A sorting system for sorting and tracking a drug before and after administration to a patient, the system comprising:

a plurality of waste container compartments for housing a plurality of removable waste containers,

wherein each of said removable waste containers comprises an opening;

at least one automatically movable lid coupled with each of said removable waste containers;

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

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

wherein each of said removable waste containers comprises a machine readable identification key, wherein said key is configured to indicate the container'"'"'s waste category type to the sorting system;

a scanner configured to read barcode information from a spent drug container,

wherein the spent drug container comprises the drug container and a spent drug, wherein the spent drug is a quantity of the drug that still remains in the drug container after said drug has been at least partially administered to a patient;

an input device configured to obtain information regarding the quantity of the spent drug,

a control system, wherein the control system is configured to compare the quantity of the spent drug with a quantity of the drug prior to administration to said patient, thereby tracking the drug before and after administration to the patient;

wherein the control system is further configured to assign the spent drug to at least one waste category based at least in part on the scanned barcode information and a waste item classification information contained in a database and automatically open the lid coupled to the removable container associated with said waste category; and

wherein the control system is further configured to lock the lid coupled to the removable container associated with said waste category after the spent drug is disposed.

12. The sorting system of claim 11, further comprising a printer to generate a manifest containing information regarding the quantity of the spent drug.

13. The sorting system of claim 11, wherein said waste item classification information comprises classification information based on environmental or drug enforcement regulations contained in a database.

14. The sorting system of claim 11, wherein the container containing said spent drug comprises a bottle, a syringe, or an intravenous (IV) bag.

15. The sorting system of claim 11, wherein at least one of said moveable lids is configured to be manually closed upon disposal of the waste item.

16. The sorting system of claim 11, wherein at least one of said moveable lids is configured to be automatically closed upon disposal of the waste item.

17. The sorting system of claim 11, further comprising an input device configured to obtain information regarding the quantity of the drug to be administered to a patient.

18. The sorting system of claim 11, wherein the input device configured to obtain information regarding the quantity of the spent drug comprises a touch screen or keyboard, wherein said information can be entered by a user upon a prompt or query.
