Abstract

A medication dispensing and timing system includes a central monitoring computer which generates and sends an address-specific medication prompting message in accordance with a prescribed medication dispensing schedule over a two-way paging system to a communicator carried by a patient. The communicator includes receiver circuitry which responds to the prompt message to generate a display and audible alarm to alert the patient. Upon the patient acknowledging the message by actuating a switch on the communicator transmitter circuitry within the pager sends a reply message to the monitoring computer. In the event that a reply message is not received within a predetermined time period following the dispensing event, the computer initiates an alternative communication procedure which includes telephone calls to 1) the patient, 2) his doctor, 3) his care provider, or 4) an emergency contact. The communicator may be equipped to electrically communicate with medication dispensing apparatus whereby the apparatus dispenses medication in response to a received prompting message. The dispensing apparatus may include a modem for communicating with the central monitoring computer to confirm actual dispensing, and to provide a control path whereby the dispensing apparatus can be controlled from the monitoring computer in the event of a radio link failure.

Claims

1. A medication dispensing system comprising:

central monitoring means for generating a prompt signal for each dosage of medication called for by a predetermined medication schedule associated with a particular patient;

a communicator including a uniquely addressed receiver associated with said patient having means for prompting said patient to take each predetermined dose of medication;

a wireless communication network for conveying said prompt signal to said uniquely-addressed receiver;

said communicator further including transmitter means responsive to an external control effect for generating a reply signal acknowledging receipt of said prompt signal;

an additional wireless communication network for conveying said reply signal to said central monitoring means; and

said central monitoring means including alarm generating means responsive to said reply signal for initiating a predetermined follow-up procedure in the absence of said reply signal following the lapse of a predetermined time period following said prompt signal.

2. A medication dispensing system as defined in claim 1 wherein said wireless communication network is a paging system, and said communicator is a two-way paging receiver.

3. A medication dispensing system as defined in claim 1 wherein said external control effect comprises a patient-actuable switch.

4. A medication dispensing system as defined in claim 1 wherein said patient prompting means comprise an alpha-numeric display viewable by the patient.

5. A medication dispensing system as defined in claim 1 wherein said patient prompting means comprise a patient-audible alarm.

6. A medication dispensing system as defined in claim 1 wherein said system includes a medication dispenser operable from said communicator whereby a predetermined dose of medication is dispensed according to a predetermined medication schedule.

7. A medication dispensing system as defined in claim 6 wherein said dispenser includes communication means for communicating with said receiver and producing a confirmation signal indicative of the dispensing of a dose of medication, and also if said dose of medication was taken from a hopper of said medication dispenser and said control effect is generated by said dispensing apparatus following receipt of said confirmation signal by said medication dispenser.

8. A medication dispensing system as defined in claim 6 wherein said dispenser includes memory means for receiving dispensing instructions from said receiver.

9. A medication dispensing system as defined in claim 6 wherein said dispenser includes memory means for keeping a detailed record of when the medication is taken.

10. A medication dispensing system as defined in claim 6 wherein a signal sent to said dispenser by said communicator includes a unique address associated with said dispenser, and said dispenser is responsive only to signals conveying said unique address.

11. A medication dispensing system as defined in claim 6 wherein said central monitoring means includes a monitoring computer, and said system includes at least one pharmacist terminal located remote from said monitoring means for conveying a patient medication schedule to the monitoring means.

12. A medication dispensing system as defined in claim 11 wherein said pharmacist terminal further conveys a unique address associated with said dispenser to said central monitoring means.

13. A medication dispensing system as defined in claim 1 wherein said central monitoring means includes a monitoring computer, and said system includes at least one pharmacist terminal located remote from said monitoring means for conveying a patient medication schedule to the monitoring means.

14. A medication dispensing system operable over a two-way paging system, said dispensing system comprising:

central monitoring means for generating a prompt signal for each dose of medication called for by a predetermined medication schedule associated with a particular patient;

a patient communicator including a uniquely addressed receiver associated with said patient having means for prompting said patient to take each predetermined dose of medication;

said patient communicator further including transmitter means responsive to an external control effect for generating a reply signal acknowledging receipt of said prompt signal;

a modem for telephone line communication between a dispenser and said central monitoring means for confirmation of dispensing to said central monitoring means and control of said dispenser by said central monitoring means; and

said central monitoring means including alarm generating means responsive to said reply signal for initiating a predetermined follow-up procedure in the absence of said reply signal following the lapse of a predetermined time period following said prompt signal.

15. A medication dispensing system as defined in claim 14 further including a wireless communication system which comprises a paging system, and said patient communicator is a two-way paging receiver.

16. A medication dispensing system as defined in claim 14 wherein said external control effect comprises a patient-actuable switch.

17. A medication dispensing system as defined in claim 14 wherein said patient prompting means comprise an alpha-numeric display viewable by the patient.

18. A medication dispensing system as defined in claim 14 wherein said patient prompting means comprise a patient-audible alarm.

19. A medication dispensing system as defined in claim 14 wherein said system includes a medication dispenser having communication means for communicating with said receiver and producing a confirmation signal indicative of the dispensing of a dose of medication, and said control effect is generated by said dispensing apparatus following receipt of said confirmation signal by said medication dispenser.

20. A medication dispensing system as defined in claim 19 wherein said dispenser includes memory means for receiving dispensing instructions from said receiver.

21. A medication dispensing system as defined in claim 20 wherein said dispensing instructions includes a unique address associated with said dispenser, and said dispenser is responsive only to signals conveying said unique address.

22. A medication dispensing system as defined in claim 19 wherein said central monitoring means includes a monitoring computer, and said system includes at least one pharmacist terminal located remote from said monitoring means for conveying a patient medication schedule to the central monitoring means.

23. A medication dispensing system as defined in claim 22 wherein said pharmacist terminal further conveys a unique address associated with said dispenser to said central monitoring means.

24. A medication dispensing system as defined in claim 14 wherein said central monitoring means includes a monitoring computer, and said system includes at least one pharmacist terminal located remote from said monitoring means for conveying a patient medication schedule to the central monitoring means.
