Abstract

The present invention is a system and method of drug identification through radio frequency identification “RFID.” The system and method is implemented where drugs are being administered, such as in a hospital or clinic, and identifies the drug being administered to the patient through the use of RFID tags and short and long range transceivers before the drug reaches the patient. After identification, the system and method is configured to cross reference the identified drug with the patient'"'"'s prescription and allergy information, and to prevent delivery to the patient, if necessary.

Claims

1. A system for identifying a drug being administered to a patient, the system comprising:

a drug source, wherein the drug source includes the drug to be administered to the patient;

a first radio frequency identification (RFID) tag affixed to the drug source, the first RIFD tag configured to emit a first radio frequency identifying the drug source;

a second RFID tag affixed to the patient, the second RFID tag configured to emit a second radio frequency identifying the patient;

a drug pump configured to dispense the drug from the drug source;

an active tag in close proximity to the first and second RFID tags, the active tag configured to receive the first and second frequencies, and further configured to emit a third radio frequency corresponding to the received radio frequencies;

a long range transceiver configured in a treatment area, and further configured to receive the third radio frequency; and

a processing means coupled to the long range transceiver, wherein the processing means processes the third radio frequency and confirms that the drug is appropriate for the patient, and further records the drug administration.

2. The system as claimed in claim 1, wherein the processing means cross-references the third radio frequency with a set of databases.

3. The system as claimed in claim 1, wherein the processing means is configured to trigger an alarm when the drug is not appropriate for the patient.

4. The system as claimed in claim 1, wherein the processing means is configured to activate a drug stop mechanism when the drug is not appropriate for the patient.

5. The system as claimed in claim 1, wherein the active tag is affixed to the drug pump.

6. The system as claimed in claim 1, wherein the drug source is a syringe.

7. The system as claimed in claim 6, wherein the drug pump is a syringe pump.

8. The system as claimed in claim 1, wherein the drug source is a drug bag, and further wherein the first RFID tag is affixed to a line running from the drug bag to the drug pump.

9. The system as claimed in claim 8, wherein the drug pump is a volumetric pump.

10. The system as claimed in claim 1, further comprising a third RFID tag fixed to a drug administrator, the third RFID tag configured to emit a fourth radio frequency identifying the drug administrator, such that the drug administrator may be recorded by the processing means.

11. The system as claimed in claim 1, wherein the drug source is a prepared medication, and the treatment area is a pharmacy, and further wherein the drug pump is not utilized and the active tag is configured in close proximity to the prepared medication.

12. The system as claimed in claim 1, wherein the active tag is a short range transceiver.

13. A method of identifying a drug being administered to a patient, the method comprising:

affixing an active tag to a drug pump, wherein the drug pump is configured to dispense the drug being administered from a drug source to the patient;

configuring a long range transceiver in a treatment area;

affixing a radio frequency (RFID) tag to the drug source, the patient and an administering personnel, wherein the RFID tag is configured to emit a first radio frequency identifying each of the drug source, the patient and the administering personnel;

reading the first radio frequency with the active tag, wherein the active tag is configured to emit a second radio frequency corresponding to the first radio frequency;

reading the second radio frequency with the long range transceiver; and

processing the second radio frequency, wherein the processing step includes confirming and recording the drug administration.

14. The method as claimed in claim 13, wherein the confirming step includes cross-referencing the second radio frequency with a set of databases.

15. The method as claimed in claim 13, further comprising triggering an alarm when the drug is not appropriate for the patient.

16. The method as claimed in claim 13, further comprising triggering a drug stop mechanism when the drug is not appropriate for the patent.

17. The method as claimed in claim 13, wherein the drug source is a syringe.

18. The method as claimed in claim 17, wherein the drug pump is a syringe pump.

19. The method as claimed in claim 13, wherein the drug source is a drug bag, and further wherein the RFID tag is affixed to a line running from the drug bag to the drug pump.

20. The method as claimed in claim 19, wherein the drug pump is a volumetric pump.

21. The method as claimed in claim 13, wherein the drug source is a prepared medication, and the treatment area is a pharmacy, and further wherein the drug pump is not utilized and the active tag is configured in close proximity to the prepared medication.

22. The method as claimed in claim 13, wherein the active tag is a short range transceiver.

23. A drug identification system, the system comprising:

a drug source, wherein the drug source includes a drug to be administered to a patient;

a first radio frequency identification (RFID) tag affixed to the drug source, the first RIFD tag configured to emit a first radio frequency identifying the drug source;

a second RFID tag affixed to the patient, the second RFID tag configured to emit a second radio frequency identifying the patient;

a third RFID tag affixed to a drug administrator, the third RFID tag configured to emit a third radio frequency identifying the drug administrator;

a drug pump configured to dispense the drug from the drug source;

a short range transceiver in close proximity to the RFID tags, the short range transceiver configured to receive the radio frequencies, and further configured to emit a fourth radio frequency corresponding to the received radio frequencies;

a long range transceiver configured in a treatment area, and further configured to receive the fourth radio frequency; and

a processing means coupled to the long range transceiver, wherein the processing means cross-references the fourth radio frequency with a set of databases to confirm that the drug is appropriate for the patient, and further records the drug administration.
