Abstract

A method for controlling medicament dispensing from a cassette moved from a mount for the cassette includes mounting the cassette fully on the mount, the cassette being loaded with bulk-form medicaments, generating a first signal indicating that the cassette is fully mounted, enabling operation of the cassette responsive to the first signal, unmounting the cassette at least partially from the mount, generating a second signal indicating that the cassette has been at least partially unmounted, and disabling further operation of the cassette responsive to the second signal even if the cassette is fully remounted. The method may include also generating a third signal indicating that the cassette is ready for further dispensing of medicaments, remounting the cassette fully on the mount, generating the first signal indicating that the cassette is fully remounted, and enabling further operation of the cassette responsive to the first and third signals after disabling further operation of the cassette.

Claims

1. A method for controlling medicament dispensing from a cassette moved from a mount for the cassette, the method comprising:

mounting the cassette fully on the mount, the cassette being loaded with bulk-form medicaments;

identifying the mounted cassette;

generating a first signal indicating that the cassette is both identified and fully mounted;

enabling operation of the cassette responsive to the first signal;

unmounting the cassette at least partially from the mount;

generating a second signal indicating that the cassette has been at least partially unmounted;

executing instructions responsive to the second signal disabling further operation of the cassette even if the cassette is both fully remounted and identified;

generating a third signal indicating that the cassette is verified as containing medicament which is correct and is ready for further dispensing of medicaments;

remounting the cassette fully on the mount before or after generating the third signal;

generating the first signal indicating that the cassette is fully remounted; and

executing instructions responsive to the first and third signals enabling further operation of the cassette.

2. The method of claim 1 wherein generating the first signal includes contacting a switch with the cassette when the cassette is fully mounted.

3. The method of claim 2 wherein generating the second signal includes spacing the cassette from the switch when the cassette is at least partially unmounted.

4. The method of claim 1 further comprising, after executing the instructions responsive to the first and third signals enabling further operation of the cassette, dispensing medicaments from the cassette.

5. The method of claim 4 wherein dispensing medicaments from the cassette includes dispensing all of the medicaments from the cassette.

6. The method of claim 4 further comprising, after unmounting the cassette at least partially from the mount, loading further bulk-form medicaments into the cassette.

7. The method of claim 6 wherein the cassette includes a lid and the method further comprises, after unmounting the cassette at least partially from the mount and before loading further bulk-form medicaments into the cassette:

allowing the lid to open when the cassette is at least partially unmounted; and

opening the lid permitting the medicaments to be loaded into the cassette.

8. The method of claim 6 further comprising, before or after loading further bulk-form medicaments into the cassette, verifying that the cassette was correctly loaded with the medicaments.

9. The method of claim 8 wherein generating the third signal includes triggering the third signal with a user-input device.

10. The method of claim 9 wherein triggering the third signal with the user-input device includes placing a finger against a fingerprint reader user-input device.

11. The method of claim 9 wherein triggering the third signal with the user-input device includes placing a finger against a touch screen video display user-input device.

12. The method of claim 9 wherein triggering the third signal with the user-input device includes reading a code associated with the cassette with a code reader user-input device.

13. The method of claim 1 wherein generating the second signal includes starting a timer with a time interval and enabling further operation of the cassette must occur before expiration of the time interval.

14. The method of claim 13 further comprising starting the timer after generating the second signal before remounting the cassette fully on the mount.

15. The method of claim 1 further comprising generating a fourth signal identifying the cassette, a fifth signal identifying a container holding a medicament for pouring into the cassette and a sixth signal identifying a match of the cassette and the container holding a medicament before enabling further operation of the cassette.

16. The method of claim 15 wherein the container holding a medicament holds an unclaimed prescription with medicaments to be restocked into the cassette.

17. The method of claim 15 wherein the container holding a medicament is a supply container which holds a quantity of medicaments to replenish the cassette.

18. A method for controlling medicament dispensing from a reloadable cassette to prevent unauthorized operation of the cassette following replenishment, the method comprising:

mounting the cassette fully on a mount, the cassette being loaded with bulk-form medicaments;

identifying the mounted cassette;

generating a first signal indicating that the cassette is both identified and fully mounted;

enabling operation of the cassette responsive to the first signal;

dispensing medicaments from the cassette;

unmounting the cassette at least partially from the mount;

generating a second signal indicating that the cassette has been at least partially unmounted; and

executing instructions responsive to the second signal disabling operation of the cassette even if the cassette is both fully remounted and identified, thereby preventing any unauthorized operation of the cassette should the cassette have been replenished after the at least partial unmounting.

19. The method of claim 18 further comprising, after executing the instructions disabling operation of the cassette:

generating a third signal indicating that the cassette is verified as containing medicament which is correct and is authorized and ready for further dispensing of medicaments;

remounting the cassette fully on the mount before or after generating the third signal;

generating the first signal indicating that the cassette is fully remounted; and

executing instructions responsive to the first and third signals enabling further operation of the cassette.

20. The method of claim 19 wherein generating the first signal includes contacting a switch with the cassette when the cassette is fully mounted.

21. The method of claim 20 wherein generating the second signal includes spacing the cassette from the switch when the cassette is at least partially unmounted.

22. The method of claim 21 further comprising, after executing the instructions responsive to the first and third signals enabling further operation of the cassette, dispensing medicaments from the cassette.

23. The method of claim 22 further comprising, after unmounting the cassette at least partially from the mount, loading further bulk-form medicaments into the cassette.

24. The method of claim 23 further comprising, before or after loading further bulk-form medicaments into the cassette, verifying that the cassette was correctly loaded with the medicaments.

25. The method of claim 24 wherein generating the third signal includes triggering the third signal with a user-input device.
