Abstract

Systems and methods are provided for dispensing medication in a predetermined amount. An exemplary system and method may include operations and/or instructions comprising dispensing medicine from a first medicine container to a transfer device; dispensing medicine from the transfer device to a second medicine container, monitoring a medicine distribution relative to the first medicine container, the second medicine container, and the transfer device by way of at least one monitoring device, and automatically adjusting the medicine distribution among the first medicine container, the second medicine container, and the transfer device.

Claims

1. A system for dispensing medication, comprising:

at least one medicine container transfer unit having a plurality of check stations, the at least one medicine container transfer unit configured to engage a medicine storage container and move the medical storage container to a first discharge point;

a medicine transfer unit positioned proximate the at least one medicine container transfer unit such that medicine discharged from the medicine storage container at the first discharge point is discharged onto the medicine transfer unit, and medicine on the medicine transfer unit is discharged from the medicine transfer unit at a second discharge point, the medicine transfer unit having a monitoring device to monitor medicine on the medicine transfer unit;

a first medicine transfer container positioned at the second discharge point to receive the medicine discharged from the medicine transfer unit;

a controller configured to perform a dispensing process that includes;

causing the medicine storage container to discharge at least a first predetermined amount of medicine from the medicine storage container onto the medicine transfer unit;

causing the medicine transfer unit to discharge at least a second predetermined amount of medicine to the first medicine transfer container;

determining whether the first medicine transfer container has an amount of medicine greater than a predetermined desired amount; and

if the amount of medicine in the first medicine transfer container is greater than the predetermined desired amount, then;

moving the first medicine transfer container to the first discharge point;

moving the medicine storage container to the second discharge point and discharge medicine remaining on the medicine transfer unit into the medicine storage container

moving a second medicine transfer container to the second discharge point; and

discharging medicine from the first medicine transfer container, onto the medicine transfer unit, and from the medicine transfer unit into the second medicine transfer container.

2. The system of claim 1, wherein the at least one medicine container transfer unit includes at least one of:

a carousel configured to rotate about a rotational center, and

a robot.

3. The system of claim 1, further comprising:

an automatic calibration and verification device;

a cleaning device; and

a vision system.

4. The system of claim 1, wherein if the amount of medicine in the second medicine transfer container is greater than the predetermined desired amount, then the dispensing process further includes:

moving the second medicine transfer container to the first discharge point;

moving the medicine storage container to the second discharge point and discharge all remaining medicine on the medicine transfer unit into the medicine storage container;

moving the first medicine transfer container to the second discharge position; and

discharging medicine from the second medicine transfer container onto the medicine transfer unit, and from the medicine transfer unit into the first medicine transfer container.

5. The system of claim 1, the controller further configured to repeat the dispensing process among the medicine storage container, medicine transfer container, and the medicine transfer unit until at least the predetermined desired amount of medicine is present in one of the medicine transfer containers.

6. The system of claim 1, wherein the plurality of check stations each includes a weight detecting device.

7. The system of claim 6, wherein the weight detecting device includes one of a scale and a load cell.

8. The system of claim 1, wherein the at least one medicine transfer unit includes one of a ramp and a conveyor extending from the first discharge point to the second discharge point.

9. The system of claim 1, wherein the monitoring device includes one of an optical sensor, a vision system, and a weight detecting device.

10. The system of claim 1, wherein the at least one medicine transfer unit includes a rotating table extending from the first discharge point to the second discharge point.

11. The system of claim 3, wherein the calibration and verification device includes multiple calibration weights with different masses.

12. The system of claim 1, further comprising a vacuum head positioned proximate the medicine transfer unit and configured to move medicine between the medicine transfer unit and at least one of the medicine containers positioned in at least one of the discharge points.

13. The system of claim 3, wherein the vision system configured to take pictures of medicine dispensed.

14. A system for dispensing medication, comprising:

at least one medicine container transfer unit, the unit having a plurality of check stations, the at least one medicine container transfer unit configured to engage a medicine storage container and move the medical storage container to a first discharge point;

a medicine transfer unit positioned proximate the medicine container transfer unit such that medicine discharged from the medicine storage container at the first discharge point is discharged onto the medicine transfer unit, and medicine on the medicine transfer unit is discharged from the medicine transfer unit at a second discharge point, the medicine transfer unit having a monitoring device to monitor medicine on the medicine transfer unit;

a first medicine transfer container positioned on one of the check stations at the second discharge point to receive the medicine discharged from the medicine transfer unit; and

a controller configured to perform a dispensing process that includes;

discharging at least a first predetermined amount of medicine from the medicine storage container to the medicine transfer unit, and at least a second predetermined amount of medicine to the first medicine transfer container; and

if an amount of medicine in the first medicine transfer container is greater than a predetermined desired amount, discharging medicine from the first medicine transfer container to the medicine transfer unit, and from the medicine transfer unit to a second medicine transfer container.

15. The system of claim 14, wherein the plurality of check stations each includes a weight detecting device.

16. The system of claim 14, wherein the medicine transfer unit includes one of a ramp and a conveyor extending from the first discharge point to the second discharge point.

17. The system of claim 14, wherein the medicine transfer unit includes a rotating table extending from the first discharge point to the second discharge point.

18. A method of using a controller to perform a dispensing process, the method comprising:

causing a medicine storage container to discharge at least a first predetermined amount of medicine from the medicine storage container onto a medicine transfer unit;

causing the medicine transfer unit to discharge at least a second predetermined amount of medicine to a first medicine transfer container;

determining whether the first medicine transfer container has an amount of medicine greater than a desired amount; and

if the amount of medicine in the first medicine transfer container is greater than the desired amount, then;

moving the first medicine transfer container to a first discharge point;

moving the medicine storage container to a second discharge point;

discharge all remaining medicine on the medicine transfer unit into the medicine storage container;

moving a second medicine transfer container to the second discharge point; and

discharging medicine from the first medicine transfer container, onto the medicine transfer unit, and from the medicine transfer unit into the second medicine transfer container.

19. The method of claim 18, wherein if the amount of medicine in the second medicine transfer container is greater than the predetermined desired amount, then:

moving the second medicine transfer container to the first discharge point;

moving the medicine storage container to the second discharge point and discharge all remaining medicine on the medicine transfer unit into the medicine storage container;
