Apparatus and Method for Improved Drug Regimen Compliance
First Claim
1. A system for monitoring the state of at least one blister card that includes a forming film, a lidding film, and a first tablet contained in a first reservoir defined by the forming film and the lidding film, wherein the system comprises:
- a housing that is operative for locating the blister card in a first position;
a first detection module comprising a first sensor, wherein the first sensor is operative for providing a first electrical signal that is based on at least one of (a) the presence of the first tablet in the first reservoir and (b) the physical state of a first dispensing region of the lidding film; and
an electronics module that is operative for providing a first output signal based on the first electrical signal.

Abstract
A method and apparatus for monitoring drug-regimen compliance is disclosed. Systems in accordance with the present invention enable automatic monitoring of the state of medicine content of a blister card. Each tablet location on the blister card is operatively coupled with a different sensor that detects whether the tablet location is occupied and/or a dispensing event at a tablet location. In some embodiments, capacitive sensing is employed, where the capacitance of each sensor is based on the physical state of a dispensing region of the lidding film of the blister pack, which is located at the tablet location being monitored. Alternative sensing approaches are based on optical, acoustic, and tactile sensors that interrogate either the dispensing region at each tablet location or the tablets themselves to determine whether tablets have been dispensed. The sensors interface with a mobile app that provides the user instructions to help improve drug-regimen compliance.
