Abstract

An ingestible dosage form includes a pill containing a pharmaceutical content and an RF tag associated with the pill. The RF tag is configured to output a wireless response signal in response to a wireless excitation signal received by the RF tag from an RF reader. The ingestible dosage form includes memory for storing pill identifying information. The wireless response signal includes the pill identifying information which may be received and processed by the RF reader. A system for monitoring patient medicine intake compliance includes a monitoring device placed within communicative proximity of ingestible dosage forms to transmit the wireless excitation signal and receive the wireless response signal including pill identifying information from the ingestible dosage forms. A device for determining an identity of a pill and quantity thereof ingested by an individual includes a nasogastric/orogastric tube having an RF tag reader attached thereto for detecting RF tagged pills.

Claims

1. A system for monitoring patient medicine intake compliance and comprising a monitoring device having a unique identifier associated therewith, wherein the monitoring device is designed to be placed within communicative proximity of a plurality of pills each having corresponding RF tags associated therewith, wherein the monitoring device is configured to:

transmit at least one wireless excitation signal at one of a manually initiated and predetermined time, wherein the at least one wireless excitation signal is configured to cause at least one of the plurality of RF tags to transmit a wireless response signal including pill identifying information;

receive the wireless response signal from the at least one RF tag; and

transmit the unique identifier of the monitoring device and the pill identifying information of the at least one RF tag,

wherein the monitoring device is configured to transmit the unique identifier and the pill identifying information by at least one of wireless, wired, and Internet-based communication links.

2. A device for determining an identity of a pill and quantity thereof ingested by an individual, the device comprising:

one of a nasogastric and orogastric tube having a free gastric end adapted for insertion into a stomach of the individual; and

an RF tag reader attached to the free gastric end of one of the nasogastric and orogastric tube, wherein the RF tag reader is configured to;

transmit at least one wireless excitation signal, wherein the at least one wireless excitation signal is configured to cause an RF tag associated with the ingested pill to transmit a wireless response signal including data stored on the RF tag; and

receive the wireless response signal from the at least one RF tag.

3. The device of claim 2, further configured to transmit the data to a computer system configured to display the data.

4. The device of claim 2, wherein the data is at least one of a unique identification code, pharmaceutical content data, manufacturer data and expiration data.
