Abstract

A system, method and apparatus for validation of medication for consumption by a patient. A patient unit, which is one node on a communication network, is operated to present medication elements stored at the patient unit in an order corresponding to the order of a prescribed course of treatment for the patient. Indicia on the medication elements are inspected to derive characterizing data such as nature of drug and scheduled time of consumption. The derived data is compared to stored data corresponding to a next scheduled medication element. If there is a match, the patient is informed that validated medication is ready to be consumed. The patient then arranges for the medication to be delivered from the patient unit and for a notification to be sent to a compliance agent at a remote network node.

Claims

a medication delivery apparatus forming a node on a communication network;

a presentation unit at the medication delivery apparatus for presenting medication elements stored at the medication delivery apparatus in an order corresponding to the order of a prescribed course of treatment for a patient, each medication element having associated indicia signifying characterizing data for the medication element an inspection unit for inspecting the indicia associated with a presented one of the medication elements to determine characterizing data for said one presented medication element;

a validation means for comparing the determined characterizing data to stored data corresponding to the course of treatment, the stored data signifying characterizing data for a medication element next scheduled to be presented;

a notification unit at the delivery apparatus operable to issue an alert at the medication delivery apparatus conditional on a valid output from the validation means; and

5. A medication delivery system as claimed in claim 1, the validation means having a valid output based on a selected one or more validation criteria, the validation criteria including:

a match in the scheduled time or period of consumption of the medication element inspected at the inspection station and the time or period of consumption of the medication next scheduled for consumption according to the stored data;

a match in the nature of the medication element inspected at the inspection station and the nature of the medication element next scheduled for consumption according to the stored data;

the present time being before an expiry date as recorded in the stored data;

the medication element inspected at the inspection station not being on any recall notice as recorded in the stored data.

6. A medication delivery system as claimed in claim 2, the medication elements stored at the medication delivery apparatus in respective containers, the indicia applied to the containers.

7. A medication delivery system as claimed in claim 6, the containers linked together in the order of the prescribed course of treatment, the containers configured as a cartridge.

8. A medication delivery system as claimed in claim 7, the cartridge comprising a roll of the containers configured to be unwound progressively to reveal, and enable access to, successive containers, the delivery mechanism operable to unroll the cartridge roll and to feed a free end of the roll to the exit zone.

9. A medication delivery system as claimed in claim 8, the delivery mechanism including a drive wheel and an idler wheel for gripping therebetween a free end portion of the cartridge roll.

10. A medication delivery system as claimed in claim 7, further comprising a separation mechanism for separating a leading container from a next-adjacent container of the cartridge.

12. A medication delivery system as claimed in claim 7, further comprising a collection unit positioned to receive and stack containers separated from a remaining part of the cartridge and presented at the exit zone.

13. A medication delivery system as claimed in claim 7, further comprising a storage unit at the medication delivery apparatus, the storage unit having a housing, the housing having a base part and a hinged part, the hinged part movable from a closed position in which the cartridge is enclosed in the housing, and an open position to permit loading and unloading of the cartridge.

14. A medication delivery system as claimed in claim 13, the delivery mechanism including a drive wheel and an idler wheel for gripping therebetween a free end portion of the cartridge roll, one of the wheels mounted on the hinged part, the wheels brought into a relative positions to grip said free end portion by the act of moving the hinged part to the closed position.

15. A medication delivery system as claimed in claim 6, the inspection module having a light source to illuminate the indicia on each container.

16. A medication delivery system as claimed in claim 15, further comprising at least one of a reader for reading said indicia and a camera for obtaining a viewable image of the indicia upon illumination thereof by the light source.

17. A medication delivery system as claimed in claim 1, further including a video conferencing functionality for providing video conferencing between the medication delivery and other nodes on the communication network.

18. A medication delivery system as claimed in claim 1, a node on the communication network remote from the medication delivery apparatus accommodating a compliance agent for monitoring compliance information issued to the network on one of a scheduled and an on-demand basis.

19. A medication delivery system as claimed in claim 1, the medication delivery apparatus further comprising a patient input functionality for summoning assistance from the network, and a patient output functionality to enable a remote agent on the network to summon the patient.

20. A medication delivery system as claimed in claim 1, further comprising control hardware and software for controlling operation of the medication delivery apparatus, at least a part of the control hardware and software located at a node on the network remote from the medication delivery apparatus.

21. A medication delivery system as claimed in claim 1, the stored data stored on the network at a location remote from the medication delivery apparatus.

22. A medication delivery system as claimed in claim 1, the stored data stored locally at the medication delivery apparatus.

11. A medication delivery system as claimed in 7, further comprising an exit aperture at the exit zone, the delivery mechanism operable to present a leading one of the containers at the exit aperture for the container to be gripped by a user, and a formation at the exit aperture constraining the user to grip the container at a position encouraging a clean separation of the container from an adjacent container.

23. A method of delivering medication comprising:

presenting medication elements stored at a medication delivery apparatus forming a node on a communication network, such presentation being in an order corresponding to the order of a prescribed course of treatment for a patient;
