Abstract

A pharmaceutical order filling system receives pharmaceutical orders and uses an automated dispensing device to dispense pharmaceuticals into containers. The automated dispensing device is configured with a filling cabinet that stores and dispenses measured quantities of pharmaceuticals and is further configured to stage measured quantities of pharmaceuticals in buffer tubes to enable efficient fulfillment of the pharmaceutical orders. Containers may be disposed on a pallet which may be moved within an automated dispensing device to place the containers under buffer tubes to receive measured quantities of pharmaceuticals from the buffer tubes into appropriate containers in an efficient manner.

First claim

The invention claimed is:

1. A pharmaceutical order filling system comprising:
an order processing device to receive a pharmaceutical order; and
an automated dispensing device comprising
a filling cabinet including a cell containing an available quantity of a pharmaceutical of the pharmaceutical order,
a prefill assembly including a buffer tube that is in communication with the cell of the filling cabinet and that is configured to stage dispensing of a plurality of measured quantities of the pharmaceutical,
wherein the automated dispensing device is communicatively coupled to the order processing device and configured to dispense a first measured quantity of the available quantity of the pharmaceutical into the buffer tube and to dispense the first measured quantity of the pharmaceutical from the buffer tube into a container, wherein the first measured quantity is selected from the plurality of measured quantities, and
wherein the cell comprising a funnel, wherein the cell is adapted to receive an insert, the insert being adapted to receive the available quantity of the pharmaceutical and to dispense the first measured quantity of the pharmaceutical through a dispensing tube of the insert, and the funnel comprising a weighted gate adapted to receive the dispensing tube of the insert.

2. The system of claim 1 , wherein the system further comprises a pallet assembly and wherein the filling cabinet is physically housed above the prefill assembly and the prefill assembly is located above the pallet assembly, and
wherein the filling cabinet is on a first, upper floor of a structure and the pallet assembly is on a second, lower floor of the structure.

3. The system of claim 1 , further comprising:
a tube that connects a stem opening of the funnel to an opening of the buffer tube.

4. The system of claim 1 , wherein the insert includes a door configured to unlock to receive the available quantity of the pharmaceutical in response to a communication from the order processing device,
wherein the communication from the order processing device is generated when an insert code on a face plate of the insert corresponds to a container code on the container.

5. The system of claim 4 , wherein the insert code corresponds to the container code when the insert code and the container code are both associated with a same pharmaceutical.

6. The system of claim 1 , wherein the buffer tube comprises a holding area adapted to receive, retain, and release the first measured quantity of the pharmaceutical.

7. The system of claim 6 wherein the holding area comprises a first holding area and a second holding area,
wherein the first holding area is adapted to receive, retain, and release the first measured quantity of the pharmaceutical,
wherein the automated dispensing device is further configured to release the first measured quantity of the pharmaceutical from the first holding area into the second holding area and to dispense a second measured quantity of the pharmaceutical into the first holding area of the buffer tube after the first measured quantity of the pharmaceutical has been released into the second holding area.

8. The system of claim 1 , wherein the automated dispensing device is configured to generate an alert when the available quantity of the pharmaceutical in the cell is less than a pre-determined level.

9. The system of claim 1 , wherein the system further comprises a pallet assembly, wherein the container is disposed on a pallet, and wherein a pallet assembly comprises an x-y movement apparatus adapted to engage and move the pallet within the pallet assembly such that the container is positioned below the buffer tube to receive the first measured quantity of the pharmaceutical.

10. The system of claim 9 , wherein an opening of the container is less than approximately 0.01 inches from a buffer tube exit of the buffer tube when the first measured quantity of the pharmaceutical is dispensed into the container.

11. The pharmaceutical order filling system of claim 1 further comprising:
a sequencing module to determine an order for dispensing each of the plurality of measured quantities of the pharmaceutical into the container.

12. The system of claim 11 , wherein the buffer tube is adapted to receive and retain the plurality of measured quantities of the pharmaceutical dispensed from the cell in communication with the buffer tube.

13. A pharmaceutical order filling system comprising:
an automated dispensing device cooperatively comprising
a filling cabinet including a plurality of cells, each cell of the plurality of cells containing a quantity of a pharmaceutical selected from a plurality of pharmaceuticals,
a prefill assembly including a plurality of buffer tubes, each buffer tube of the plurality of buffer tubes being in respective communication with a particular cell of the plurality of cells,
a pallet assembly including an x-y movement apparatus adapted to engage and move a pallet within the pallet assembly, wherein a plurality of containers are disposed on the pallet, and
a first cell of the plurality of cells comprising a funnel, wherein the first cell is adapted to receive an insert comprising a dispensing tube, and wherein the dispensing tube is adapted to engage and push open a funnel gate of the funnel when the insert is in the cell, and
wherein the automated dispensing device is configured to dispense a first measured quantity of a first pharmaceutical from the first cell into a first holding area of a first buffer tube uniquely associated with the first cell and to dispense the first measured quantity of the first pharmaceutical from the first holding area of the first buffer tube into a first container when the first container is positioned below the first buffer tube, wherein the first pharmaceutical is among the plurality of pharmaceuticals, the first cell is among the plurality of cells, the first buffer tube is among the plurality of buffer tubes, and the first container is among the plurality of containers.

14. The system of claim 13 wherein the first buffer tube further comprises a second holding area and wherein the automated dispensing device is further configured to release the first measured quantity of the first pharmaceutical into the second holding area and to dispense a second measured quantity of the first pharmaceutical into the first holding area of the first buffer tube after the first measured quantity of the first pharmaceutical has been released into the second holding area.

15. The system of claim 13 wherein each of the plurality of buffer tubes is shaped as a long-draw funnel.

16. The system of claim 13 wherein the insert comprises a hopper, a vibratory bowl, and a level sensor, wherein the level sensor is configured to cause the hopper to spin and to release a released quantity of the first pharmaceutical into the vibratory bowl 906 , wherein the released quantity of the first pharmaceutical comprises at least a portion of the first measured quantity of the first pharmaceutical.

17. The system of claim 13 wherein the first buffer tube comprises a buffer tube gate configured to release the first measured quantity of the first pharmaceutical from the first holding area, wherein the buffer tube gate is configured to flutter by opening and closing in quick succession.

18. The system of claim 13 wherein the pallet assembly comprises a lift apparatus configured to the pallet and lift the pallet such that the first container is aligned to receive the first measured quantity of the first pharmaceutical from the first bu
