Abstract

Described herein are embodiments of systems and methods for providing an automated medication handling system that can, among other things, single-dose package medications, store and dispense medications in a pharmacy, transport medications to a nursing unit or other remote location, store them at that remote location, and load them into a portable unit carried by a nurse, who may dispense the medication at a bedside.

Claims

1. A system for managing medications in a care facility, comprising:

a plurality of medication containers, each of the plurality of medication containers including at least one machine-readable identifier and configured to contain a dose of a medication and configured to allow replacement of the dose of the medication with a dose of another medication; and

a dispenser comprising;

a plurality of storage locations, each storage location configured to store one of the plurality of medication containers, and to allow retrieval of one of the plurality of medication containers without having to remove any of the remaining plurality of medication containers from their corresponding storage locations;

a detector configured to read the at least one machine-readable identifier of each of the plurality of medication containers while each of the plurality of the medication containers is located in its corresponding storage location; and

a selection device configured to retrieve each of the plurality of medication containers when the corresponding medication container falls from its corresponding storage location.

2. The system of claim 1, wherein the dispenser further comprises a processor configured to (1) store information associated with the at least one machine-readable identifier for each of the plurality of medication containers, wherein the information includes at least one of a medication name, a dosage, a manufacturer, a lot date number, and an expiration date, (2) receive an input comprising an identification of a drug and a dose of the drug to be dispensed, (3) select one of the plurality of medication containers to be retrieved that corresponds to the identified drug and the dose of the drug, and (4) identify, to the selection device, the storage location containing the selected one of the plurality of medication containers.

3. The system of claim 2, wherein the selected one of the plurality of medication containers is selected by the processor because the selected one of the plurality of medication containers has the earliest expiration date of each of the plurality medication containers that corresponds to the identified drug and the dose of the drug.

4. The system of claim 2, wherein the processor is further configured to identify, to the selection device, at least one of the plurality of medication containers that contains expired medications.

5. The system of claim 2, further comprising a transport robot that is configured to convey the plurality of medication containers between the dispenser and a storage unit comprising another plurality of storage locations, each of the another plurality of storage locations configured to store one of the plurality of medication containers.

6. The system of claim 5, wherein the processor determines which of the plurality of medication containers is to be conveyed by the transport robot based on information obtained from the detector.

7. The system of claim 1, wherein the at least one machine-readable identifier comprises at least one of a barcode, a radio-frequency identification tag, and a two-dimensional matrix.

8. The system of claim 1, further comprising a medication picker system that locates a desired one of the plurality of medication containers at a first location and secures the desired one container for transportation to a second location.

9. The system of claim 1, further comprising a tray that retains a subset of the plurality of medication containers, the tray being conveyed between a storage unit and a dispensing unit by a transport robot.

10. The system of claim 1, wherein the detector comprises a camera that obtains an image of the machine-readable identifier.

11. The system of claim 1, wherein the detector is further configured to conduct an inventory of the plurality of medication containers stored in the dispenser.

12. The system of claim 1, wherein the dispenser is further configured to receive additional medication containers, identify the additional medication containers, and store the additional medication containers without input of additional information or action by an operator.

13. The system of claim 12, wherein the dispenser positions each of the additional medication containers within the dispenser based upon information from the corresponding machine-readable identifier of the additional medication containers read by the detector.

14. A method for managing medications in a care facility, comprising:

providing a plurality of medication containers, each of the plurality of medication containers including at least one machine-readable identifier, and configured to contain a dose of a medication, and configured to allow replacement of the dose of the medication with a dose of another medication;

storing, in one of a plurality of storage locations within a dispenser, one of the plurality of medication containers;

reading the at least one machine-readable identifier of one of the plurality of medication containers while the one of the plurality of medication containers is located in its corresponding storage location; and

retrieving one of the plurality of medication containers when the corresponding medication container falls from its corresponding storage location without having to remove any of the remaining plurality of medication containers from their corresponding storage locations.

15. The method of claim 14, wherein retrieving the one of the plurality of medication containers is in response to a recall of the medication contained in the one of the plurality of medication containers.

16. The method of claim 14, further comprising relocating the retrieved one of the plurality of medication containers because the medication included in the one of the plurality of medication containers was not administered to a patient by a caregiver.

17. The method of claim 14, further comprising

storing information associated with the at least one machine-readable identifier for each of the plurality of medication containers, wherein the information includes at least one of a medication name, a dosage, a manufacturer, a lot date number, and an expiration date,

receiving an input comprising an identification of a drug and a dose of the drug to be dispensed;

and

selecting one of the plurality of medication containers to be retrieved, wherein the selected one of the plurality of medication containers corresponds to the identified drug and the dose of the drug,

wherein the retrieving the selected one of the plurality of medication containers comprises identifying the storage location containing the selected one of the plurality of medication containers.

18. The method of claim 17, wherein the selected one of the plurality of medication containers is selected because the selected one of the plurality of medication containers has the earliest expiration date of each of the plurality medication containers that corresponds to the identified drug and the dose of the drug.

19. The method of claim 17, further comprising returning unused medications to the storage facility based on the expiration date associated with the medications.

20. The method of claim 14, further comprising conducting an inventory of the plurality of medication containers.

21. The method of claim 14, further comprising:

receiving additional medication containers;

identifying the additional medication containers; and

storing the additional medication containers without input of additional information or action by an operator.

22. The method of claim 14, further comprising relocating the retrieved one of the plurality of medication containers to a tray within a storage facility.

23. The method of claim 22, further comprising transporting the tray based on information from the machine-readable identifier included with the one of the plurality of medication containers.

24. The method of claim 23, wherein transporting the tray comprises transporting the tray with a transport robot.
