Abstract

A system for the remote monitoring of in-home self-medication to assure compliance with prescribed dosage schedules. The system comprises at least one subscriber home medication station which interfaces with a communications link and a remote central monitoring station also interfaced with the link and operative to receive and analyze messages transmitted by the home medication station. The preferred home medication station embodiment transmits messages to the central station over the communications link each time the home medication station is accessed for a dosage of medication. Central station computer means verify receipt of such signals within each subscriber'"'"'s uniquely scheduled dosage time windows, and alert an operator to take appropriate action if a dosage schedule error is detected. Alternative home medication station embodiments utilize a built-in programmable timer module to verify accessing of medication within a subscriber'"'"'s uniquely scheduled dosage time windows, and to initiate transmission of alarm signals to the central station over the communications link if dosage schedule errors are detected by the timer module. All embodiments provide subscribers with help-button means to initiate transmission of alarm messages to the central station over the communications link in event of adverse reaction to medication, or other emergencies. Since the central station will be alerted if any scheduled dosage is missed, no emergency rendering a subscriber unable to press a help-button or call for help can go undetected longer than the maximum time between consecutively scheduled dosages.

Claims

1. A self-medication monitoring system for monitoring subscriber compliance with uniquely prescribed medication dosage schedules via a communication link, comprising:

a subscriber remote station for transmission of information corresponding to a subscriber'"'"'s self-medication activities via said communication link, said subscriber remote station further comprising;

a switch means operative to generate predetermined signals corresponding to a subscriber'"'"'s self-medication activities in response to said subscriber'"'"'s self-medication activities; and

a communicator means operative to be activated by said generated predetermined signals to responsively transmit corresponding predetermined subscriber self-medication activity messages to the central station via said communications link;

a central monitoring station for receiving, via said communication link, and processing the information corresponding to a subscriber'"'"'s self-medication activities to alarm monitor subscriber compliance with uniquely prescribed medication dosage schedules, said central monitoring station further comprising;

a processor means operative at the central station to uniquely preschedule non-overlapping daily medication dosage time windows of the same or varying time width for each subscriber, one such time window for each of a subscriber'"'"'s prescribed daily dosages, each said time window bounded by a unique opening time and a unique closing time specified by or for said subscriber, wherein said subscriber'"'"'s compliance with prescribed medication dosage schedules can be inferred if each of said subscriber self-medication activity messages is received at said central station within its respective prescheduled time window; and

a processor means operative at said central station to alarm monitor said self-medication activity messages to assure that compliance with the subscriber'"'"'s prescribed medication dosage schedules is indicated within each of said subscriber'"'"'s prescheduled time windows, and at no other times.

2. The self-medication monitoring system of claim 1, wherein said remote station is configured as a home medication station for storing said subscriber'"'"'s prescription medication in a simple container of predetermined shape and volume, said remote station further comprising a storage compartment for storing said prescription medication directly or in package means adapted to meet said subscriber'"'"'s needs, and lid means operative to be opened by said subscriber to gain access to said medication, wherein said switch means is actuated each time said lid means is opened and closed.

3. The self-medication monitoring system of claim 1, wherein said remote station further includes two-way audio means operative to enable two-way voice communications between said central station and said remote station via said communication link upon occurrence of predetermined alarm conditions.

4. The self-medication monitoring system of claim 1, wherein said remote station further includes a miniature radio receiver which receives RF signals of predetermined frequency from at least one miniature portable wireless help-button RF transmitter, and responsively activates said communicator means to become operative to responsively transmit a predetermined alarm message to said central station via said communication link.

5. The self-medication monitoring system of claim 1, wherein said remote station further includes at least one help-button switch, which when actuated causes said communicator means to become operative to responsively transmit a predetermined alarm message to said central station via said communication link.

6. A self-medication monitoring system for monitoring subscriber noncompliance with uniquely prescribed medication dosage schedules and for transmission of noncompliance information over a communication link to a central monitoring station, comprising:

a subscriber remote station for monitoring information indicative of subscriber noncompliance with uniquely prescribed medication dosage schedules and for transmission of noncompliance information via said communication link, said subscriber remote station further comprising;

a switch means operative to generate predetermined signals corresponding to a subscriber'"'"'s self-medication activities in response to said subscriber'"'"'s self-medication activities;

a programmable timer means operative to uniquely preschedule non-overlapping daily medication dosage time windows of the same or varying time width for any subscriber, one such time window for each of a subscriber'"'"'s prescribed daily dosages of medication, each said time window bounded by a unique opening time and a unique closing time specified by or for said subscriber, wherein said subscriber'"'"'s prescribed medication dosage schedule compliance can be inferred if each of said subscriber self-medication activity messages is generated within it'"'"'s respective prescheduled time window;

a programmable timer means operative to monitor said self-medication activity messages to assure that compliance with the subscriber'"'"'s prescribed medication dosage schedules is indicated within each of said subscriber'"'"'s prescheduled time windows, and at no other times, and to responsively output subscriber alert signals upon detection of any indicated noncompliance;

a local annunciator means operative to be activated in response to said subscriber alert signals;

a programmable timer means operative to responsively output alarm signals if said subscriber does not take predetermined action to correct said noncompliance within a predetermined time after activation of said local annunciator means by said alert signals; and

a communicator means operative to be activated by said alarm signals to responsively transmit predetermined alarm messages to said central station via said communications link.

7. The self-medication monitoring system of claim 6, wherein said remote station is configured as a home medication station for storing said subscriber'"'"'s prescription medication in a simple container of predetermined shape and volume, said remote station further comprising a storage compartment and lid means operative to be opened by said subscriber to gain access to said medication, for storing said prescription medication directly or in package means adapted to meet said subscriber'"'"'s needs, wherein said switch means is actuated each time said lid means is opened and closed.

8. The self-medication monitoring system of claim 6, wherein said remote station further includes two-way audio means operative to enable two-way voice communications between said central station and said remote station via said communication link upon occurrence of predetermined alarm conditions.

9. The self-medication monitoring system of claim 6, wherein said remote station further includes a miniature radio receiver which receives RF signals of predetermined frequency from at least one miniature portable wireless help-button RF transmitter, and responsively activates said communicator means to become operative to responsively transmit a predetermined alarm message to said central station via said communication link.

10.
