Abstract

Disclosed is an apparatus and system for monitoring drug regimen compliance, the system utilizing a Radio Frequency Identification (RfID) tag affixed to a pharmaceutical agent and a wearable RFID reader that identifies a patient. The RFID tag identifies the pharmaceutical agent and the RFID reader wirelessly communicates with a central monitoring system upon ingestion of the pharmaceutical agent.

Claims

1-18. -18. (canceled)

19. A system for monitoring drug regimen compliance, the system comprising:

a Radio Frequency Identification (RFID) tag affixed to and identifying a pharmaceutical agent; and

a wearable RFID reader that identifies a patient,

wherein the RFID reader wirelessly communicates with a central monitoring system upon ingestion by the patient of the pharmaceutical agent.

20. The system of claim 19, further comprising a database updated by the central monitoring system upon communication of ingestion.

21. The system of claim 19, further comprising a harness worn by a patient.

22. The system of claim 21, wherein the harness positions the RFID reader adjacent to the patient'"'"'s throat.

23. The system of claim 21, wherein the RFID reader is fixably secured to the harness.

24. The system of claim 23, wherein the harness wirelessly communicates an alarm when unfastened.

25. The system of claim 20, wherein an identification of each of a plurality of harnesses respectively worn by a plurality of patients is wirelessly communicated.

26. The system of claim 19, wherein, upon detection of ingestion of the pharmaceutical agent, the database is updated to indicate drug regimen compliance by the patient.

27. The system of claim 26, wherein an alarm is provided to a caregiver when the database is not updated at a predetermined interval.

28. The system of claim 27, wherein the alarm identifies a patient not in compliance with the prescribed drug regimen.

29. The system of claim 25, wherein a report is generated at regular intervals showing ingestion detection times for each patient among the plurality of patients.

30. The system of claim 29, wherein the database includes historical trends for each of the plurality of patients and the report shows deviations from the historical trends.

31. The system of claim 19, wherein the RFID tag is encapsulated with biocompatible material insoluble in a patient gastrointestinal tract, with a polymer deposited on the capsule.

32. The system of claim 31, wherein only an antenna of the RFID tag is exposed in the gastrointestinal tract.

33. The system of claim 31, wherein the polymer becomes conductive upon detection of a pH value exceeding a predetermined threshold.

34. The system of claim 31, wherein the polymer becomes conductive upon ingestion, the wearable RFID reader establishes a wireless link between the RFID reader and the RFID tag based on inductive coupling between an antenna of the RFID reader and an antenna of the RFID tag identifying the RFID tag.

35. The system of claim 19, wherein the patient is identified by RFID polling of a second RFID tag affixed to a bracelet worn by the patient.

36. A portable monitor comprising a wearable Radio Frequency Identification (RFID) reader for wirelessly communicating with a remote monitoring system upon detection of ingestion of a pharmaceutical agent having an RFID tag affixed thereto.

37. The portable monitor of claim 36, wherein the RFID reader is affixed to a harness worn by a patient.

38. The portable monitor of claim 37, wherein the harness positions the RFID reader adjacent to the patient'"'"'s throat and an alarm is wirelessly communicated when the harness is unfastened.
