Abstract

A method for dispensing at least two medications to a patient, the method comprising the steps of: automatically dispensing at least one first medication to a patient according to a predetermined dosage level; receiving (203) a request from the patient for a second medication; determining (207, 215) the total dispensed dosage of the at least one first medication and the second medication for the patient; providing (209, 211, 213, 217, 219, 223) an indication if the determined dispensed dosage is equal to or greater than a predetermined maximum dosage; and dispensing (225) the requested second medication if the determined dispensed dosage is less than or equal to the predetermined maximum dosage.

Claims

1. A method for dispensing at least two medications to a patient, the method comprising with a processor the steps of:

controlling a first dispensed channel to dispense a predetermined first medication dosage of a first medication to a patient;

receiving a request from said patient for a second medication dosage of a second medication which second medication interacts with the first medication;

determining a total dosage of said dispensed first medication and said requested second medication for said patient;

providing an indication if said determined total dispensed dosage is equal to or greater than a predetermined maximum total dosage; and

dispensing said requested second medication if said determined dispensed dosage is less than or equal to said predetermined maximum total dosage.

2. The method according to claim 1, wherein the method further comprises the step of:

with an alarm or display, providing an indication if at least one predetermined requirement for dispensing at least one of said first medication dosage of said one first medication and the second medication dosage of the second medication is not met.

3. The method according to claim 1, wherein said step of providing the indication if said determined dosage is equal to or greater than the predetermined maximum total dosage comprises the steps of:

dispensing said requested second medication dosage of said second medication; and

issuing an alert to said patient indicating the maximum predetermined total dosage has been reached and the requested second medication is still being dispensed.

4. The method according to claim 1, wherein said step of providing the indication if said determined total dosage is equal to or greater than the predetermined maximum total dosage comprises the steps of:

preventing the dispensing of said requested second medicine dosage of said requested second medication; and

issuing an alert to said patient indicating the maximum predetermined total dosage has been reached and the medication is not being dispensed.

5. The method according to claim 3, wherein said step of issuing the alert to said patient comprises the step of:

with a transmitter, transmitting said alert and information data relating to the first and second medication dispensed, the second medication requests, and first and second medications not taken by the patient to a remote node.

6. The method according to claim 1, wherein the step of providing the indication if said determined dosage is equal to or greater than the predetermined maximum total dosage comprises the steps of:

requesting a confirmation from said patient;

dispensing said requested second medication in response to receiving said confirmation; and

preventing the dispensing of said requested second medication in response to no confirmation being received.

7. An apparatus for dispensing at least two interacting medications to a patient, the apparatus comprising:

a first dispensing channel which dispenses at least one first medication of a predetermined first dosage;

a second dispensing channel which dispenses a second medication in response to receipt of a request from said patient to dispense a second dosage of the requested second medication;

a processor configured to determine a total dosage of said at least one first medication and said requested second medication; and

an indicator which provides an alert to said patient in response to said determined total dosage being equal to or greater than the predetermined maximum total dosage.

8. The apparatus according to claim 7, wherein the processor is further configured to:

control said second dispensing channel to prevent the second dispensing channel from dispensing said second medication in response to the determined total dosage of the dispensed at least one first medication and the requested second medication exceeding the predetermined maximum total dosage.

9. The apparatus according to claim 7, wherein the indicator includes a display which provides a visual alarm to said patient in response to the determined total dosage being equal to or greater than the predetermined maximum total dosage.

10. The apparatus according to claim 7, wherein the indicator includes a loud speaker which provides an audio alarm to said patient in response to the determined total dosage being equal to or greater than the predetermined maximum total dosage.

11. The apparatus according to claim 7, further including:

a transmitter which transmits the alert and information data relating to medication dispensed, medication requests and medications not taken to a remote node.

12. An apparatus for dispensing at least two medications which adversely interact to a patient, the apparatus comprising a processor programmed to:

control a first dispensing channel to dispense a prescribed medication on a predetermined schedule;

control a second dispensing channel to dispense a take-when-needed medication on request;

receive a request from the patient for a dose of the take-when-needed medication;

determine whether there is an adverse interaction between a previously delivered dosage of the prescribed medication and the requested dose of the take-when-needed medication and send an indication to the patient if the adverse interaction determined; and

determine if the previously dispensed dosage of the prescribed medication and the requested dose of the take-when-needed medication for the patient is equal to or greater than a predetermined maximum total dosage.

13. The apparatus according to claim 12, wherein the processor is further programmed to:

in response to determining the adverse interaction, warn the patient of the adverse interaction and dispense the requested dose of the take-when-needed medication.

14. The apparatus according to claim 12, wherein the processor is further programmed to:

in response to determining the adverse interaction, warn the patient of the adverse interaction and prevent the take-when-needed medication from being dispensed.

15. The apparatus according to claim 12, wherein the processor is further programmed to, in response to determining the adverse interaction:

request a confirmation from said patient;

control the second dispensing channel to dispense the requested dose of the take-when-needed medication in response to receiving said confirmation; and

prevent the second dispensing channel from dispensing of the requested dose of the take-when-needed medication in response to no confirmation being received.
