Abstract

A medication dispensing unit is provided for tracking medical products having a Radio Frequency Identification (RFID) tag uniquely associated therewith. The dispensing unit includes compartments for receiving medical products therein, and readers for reading the RFID tags associated with the medical products in the compartments. A processor is coupled to the readers for receiving and processing readings of the RFID tags in the compartment to identify the medical products in the compartments. The processor may identify a medical product removed from a compartment by determining a difference between readings of the RFID tags in the compartment taken before and after the medical product is removed from the compartment. The processor may verify that the medical product removed from the compartment is authorized to be removed or confirmed that an identified patient is intended to receive the medical product being removed from the compartment. A system and method for counterfeit prevention is disclose, as is specimen, blood, organ and the like, tracking.

Claims

1. An apparatus for tracking unit dose medical products, each of the medical products having a Radio Frequency Identification (RFID) tag uniquely associated therewith, the apparatus comprising:

a casing comprising a compartment for receiving one or more medical products therein;

a reader for reading the RFID tags associated with the medical products in the compartment, the reader including a plurality of RFID antennas disposed in the casing; and

a processor coupled to the reader for receiving and processing readings of the RFID tags in the compartment to identify the medical products in the compartment, and wherein the processor identifies a medical product removed from the compartment by determining a difference between readings of the RFID tags in the compartment taken before and after the medical product is removed from the compartment, and wherein the processor monitors the time period between the time a medical product is removed and the time the medical product is to be administered to a patient if the medical product is of limited stability.

2. Apparatus as in claim 1 wherein the reader comprises a plurality of RFID antennas disposed beneath the compartment.

3. Apparatus as in claim 2 wherein the reader comprises a plurality of RFID antennas mounted on the bottom of the compartment.

4. Apparatus as in claim 1 wherein the reader comprises a plurality of RFID antennas disposed over the compartment.

5. Apparatus as in claim 1 wherein the reader comprises a plurality of RFID antennas disposed beside the compartment.

6. The apparatus of claim 1 wherein the processor verifies that the medical product removed from the compartment is authorized to be removed by comparing a product identifier associated with the RFID tag of the removed medical product to a product identifier of a medical product authorized to be removed from the compartment.

7. The apparatus of claim 6 wherein the product identifier comprises at least one of a product name, a product serial number, a product lot number, and a patient identifier.

8. The apparatus of claim 1 further comprising a display coupled to the processor, and wherein the processor displays a mismatch notification on the display when the processor detects a mismatch between the product identifier read from the RFID tag of the removed medical product and the product identifier of the medical product authorized to be removed.

9. The apparatus of claim 8 wherein the mismatch notification comprises the product identifier read from the RFID tag of the removed medical product and the product identifier of the medical authorized to be removed.

10. The apparatus of claim 1 wherein the casing comprises a plurality of compartments, and wherein the reader comprises a plurality of readers including antennas for reading the RFID tags of medical products in respective compartments.

11. The apparatus of claim 1 further comprising an input device coupled to the processor for identifying a patient to be associated with one or more medical products being removed from the compartment.

12. The apparatus of claim 1 further comprising a return compartment for returning unused medical products, and a reader for reading an RFID tag of any returned medical product.

13. An apparatus as in claim 1 wherein the compartment includes individual sections for each receiving a medical product.

14. An apparatus as in claim 13 wherein the compartments are adapted to receive different pharmaceutical medical products.

15. An apparatus as in claim 1 wherein the medical products comprise pharmaceutical products.

16. An apparatus as in claim 1 wherein the medical products comprise blood samples.

17. An apparatus as in claim 1 wherein the medical products comprise human organs.

18. An apparatus for tracking unit dose medical items, each of the medical items having a Radio Frequency Identification (RFID) tag uniquely associated therewith, the apparatus comprising:

a casing comprising a compartment for receiving one or more medical products therein,

a terminal associated with the casing at which items intended for a patient can be selected,

a reader for reading the RFID tags associated with the medical products in the compartment, the reader including a plurality of RFID antennas disposed in the casing; and

a processor coupled to the reader for receiving and processing readings of the RFID tags in the compartment to identify the medical products in the compartment and to verify that a unit dose item removed is authorized to be removed and the removed item is assigned to an individual patient as the item is removed, and wherein the processor monitors the time period between the time a medical product is removed and the time the medical product is to be administered to a patient if the medical product is of limited stability.

19. An apparatus for tracking unit dose medical products, each of the medical products having a Radio Frequency Identification (RFID) tag uniquely associated therewith, the apparatus comprising:

a dispensing terminal for receiving one or more medical products,

a reader for reading the RFID tags associated with the medical products, the reader including an RFID antenna disposed at the terminal; and

a processor coupled to the reader for receiving and processing readings of the RFID tags to identify the medical products at the terminal, and wherein the processor identifies a medical product removed from the terminal by determining a difference between readings of the RFID tags at the terminal taken before and after the medical product is removed from the terminal, and wherein the processor monitors the time period between the time a medical product is removed and the time the medical product is to be administered to a patient if the medical product is of limited stability.

20. The apparatus of claim 19 wherein the processor verifies that the medical product removed from the terminal is authorized to be removed by comparing a product identifier associated with the RFID tag of the removed medical product to a product identifier of a medical product authorized to be removed from the terminal.

21. The apparatus of claim 20 wherein the product identifier comprises at least one of a product name, a product serial number, a product lot number, and a patient identifier.

22. The apparatus of claim 19 further comprising a display coupled to the processor, and wherein the processor displays a mismatch notification on the display when the processor detects a mismatch between the product identifier read from the RFID tag of the removed medical product and the product identifier of the medical product authorized to be removed.

23. The apparatus of claim 19 wherein the terminal comprises a plurality of compartments, and wherein the reader comprises a plurality of readers including antennas for reading the RFID tags of medical products in respective compartments.

24. The apparatus of claim 23 further comprising an input device coupled to the processor for identifying a patient to be associated with one or more medical products being removed from the compartment.

25. An apparatus as in claim 19 wherein the medical products comprise pharmaceutical products.
