Abstract

A medication dispenser provides automation to the steps of locating and acquiring medications to be administered to a patient. The medication dispenser includes an enclosure providing a secure environment for storing medications in multiple sized medication-storage bins. The medication storage bins are hung in storage racks located within the enclosure. A robot system is also provided within the enclosure for moving bins between the storage racks and a medication dispensing area. The medication dispensing area includes doors configured to open to define an opening for passing a selected bin through the enclosure. In some embodiments, the doors provide a variable-sized opening and, in some instances, the opening matches the size of a bin containing medications selected for dispensing.

Claims

1. A medication dispensing apparatus comprising:

an enclosure;

a plurality of different-sized medication storage bins located at a plurality of storage locations within the enclosure, each medication storage bin being configured to hold one or more medically related items;

a medication dispensing area having one or more doors in the enclosure for passing a selected medication storage bin through the enclosure, wherein the one or more doors are configured to open to define an opening of variable size; and

a robot system for moving the selected medication storage bin between a corresponding storage location within the enclosure and the medication dispensing area.

2. The medication dispensing apparatus of claim 1, further comprising a plurality of racks within the enclosure, the plurality of racks providing the plurality of storage locations for storing the plurality of medication storage bins.

3. The medication dispensing apparatus of claim 1, wherein the medically related items comprise one or more of the following:

unit-dose medications, multi-dose medications, syringes, ampules, vials, oral suspensions, tubes, jars, oral solids, and medical supplies.

4. The medication dispensing apparatus of claim 1, wherein the medication dispensing apparatus further comprises a large item dispensing drawer for storing and dispensing medically related items that are too large to be stored in the medication storage bins.

5. The medication dispensing apparatus of claim 1, wherein each medication storage bin includes one or more rails disposed on a bottom of the medication storage bin to facilitate movement of the medication storage bin within the medication dispensing apparatus.

6. The medication dispensing apparatus of claim 5, wherein the robot system comprises:

a platform; and

one or more belt systems for engaging the one or more rails on the selected medication storage bin and moving the selected medication storage bin on and off the platform.

7. The medication dispensing apparatus of claim 5, wherein the medication dispensing area includes one or more belt systems for engaging the one or more rails on the selected medication storage bin and moving the selected medication storage bin across the medication dispensing area and through the one or more doors.

8. The medication dispensing apparatus of claim 1, wherein each medication storage bin includes one or more identifiers for identifying the medication storage bin.

9. The medication dispensing apparatus of claim 8, wherein the one or more identifiers comprise one or more of the following:

a radio frequency identifier tag, a bar code, and a magnet.

10. The medication dispensing apparatus of claim 8, wherein the robot system includes at least one detector for detecting at least one of the one or more identifiers on the medication storage bins to identify the medication storage bins.

11. The medication dispensing apparatus of claim 10, wherein the at least one detector comprises one or more of the following:

a radio frequency identifier reader, a bar code scanner, and a hall effect sensor.

12. The medication dispensing apparatus of claim 8, wherein the medication dispensing area includes at least one detector for detecting at least one of the one or more identifiers on the medication storage bins to identify the medication storage bins.

13. The medication dispensing apparatus of claim 1, wherein the one or more doors are configured to open to define the opening based on a size of the selected medication storage bin.

14. The medication dispensing apparatus of claim 13, wherein the one or more doors are configured to open to match the size of the selected medication storage bin.

15. The medication dispensing apparatus of claim 1, wherein the medication storage bins are located at storage locations within the enclosure based on a frequency of use of medically related items contained in each medication storage bin.

16. A method for dispensing medications from a medication dispensing apparatus, the method comprising:

receiving a selection of a medically related item;

determining a medication storage bin containing the medically related item, the medication storage bin being located at a storage location within the medication dispensing apparatus;

determining the storage location of the medication storage bin within the medication dispensing apparatus;

using a robot system within the medication dispensing apparatus to retrieve the medication storage bin from the storage location and move the medication storage bin to a medication dispensing area, the medication dispensing area having one or more doors in an enclosure of the medication dispensing apparatus for passing the medication storage bin through the enclosure;

opening the one or more doors to define an opening in the enclosure; and

moving the medication storage bin through the opening in the enclosure created by opening the one or more doors.

17. The method of claim 16, wherein the one or more doors are configured to provide a variable-sized opening and wherein the one or more doors are opened to define the opening based on a size of the medication storage bin.

18. The method of claim 17, wherein opening the one or more doors based on the size of the medication storage bin comprises using a detector located at the medication dispensing area to detect an identifier on the medication storage bin to determine the size of the medication storage bin.

19. The method of claim 16, wherein the method further comprises:

receiving a selection of a second medically related item;

determining a second medication storage bin containing the second medically related item, the second medication storage bin being located at a second storage location within the medication dispensing apparatus;

determining the second storage location of the second medication storage bin within the medication dispensing apparatus;

using the robot system within the medication dispensing apparatus to retrieve the second medication storage bin from the second storage location and move the second medication storage bin to a second medication dispensing area, the second medication dispensing area having one or more second doors in the enclosure of the medication dispensing apparatus for passing the second medication storage bin through the enclosure;

upon determining that the medication storage bin has been returned through the medication dispensing area and the one or more doors have been closed, opening the one or more second doors to match a size of the second medication storage bin; and

moving the second medication storage bin through an opening in the enclosure created by opening the one or more second doors.

20. The method of claim 16, wherein the method further comprises:

receiving a command to return the medication storage bin;

moving the medication storage bin through the opening in the enclosure;

closing the one or more doors; and

using the robot system to move the medication storage bin from the medication dispensing area to the storage location within the medication dispensing apparatus.
