Abstract

A medication dispenser for use in a hospital or other medical setting comprises a plurality of containers for holding medication units, packaging apparatus for containing one or more medication units in a package and robotics for manipulating a selected container to transfer one or more medication units from the container directly to said package. Since medication is directly transferred from the container to the package, no cross-contamination occurs.

Claims

1. Apparatus for dispensing medication in a hospital comprising:

a plurality of containers for holding medication units;

a plurality of holders for holding one or more medication units from associated containers;

an imaging system for generating an image of the medication units in a selected holder to determine whether a desired number of medication units are present;

packaging apparatus for containing one or more medication units in a package; and

robotics for manipulating a holder to transfer one or more medication units from the container directly to said package.

2. The apparatus of claim 1 and further comprising a storage module for holding a plurality of said containers.

3. The apparatus of claim 2 wherein said storage module comprising a rotating carousel having a plurality of receptacles disposed thereon for receiving respective containers.

4. The apparatus of claim 1 wherein each holder is coupled to an associated container.

5. The apparatus of claim 4 and further comprising control circuitry for controlling said robotics to manipulate said containers to place said desired number of medication units in the associated holder.

6. The apparatus of claim 1 wherein said packaging apparatus comprises:

holding means for holding packaging material; and

apparatus for opening a pocket in said packaging material into which said one or more medication units are transferred.

7. The apparatus of claim 1 and further comprising an interface to a hospital pharmacy system for retrieving data therefrom.

8. The apparatus of claim 1 and further comprising a user interface for receiving instructions from a user and issuing instructions to cause transfer of said medication units from said containers to said packaging apparatus.

9. The apparatus of claim 8 and further comprising control circuitry coupled to said user interface, said packaging apparatus and said robotics.

10. The apparatus of claim 9 and further comprising a printer coupled to said user interface for printing reports.

11. A system of dispensing medications throughout a hospital comprising:

circuitry for maintaining a database of information associated with patient medication orders; and

a plurality of medication dispensers for dispensing medication responsive to said database of information, each dispenser comprising;

a plurality of containers for holding medication units;

a plurality of holders for holding one or more medication units from associated containers;

an imaging system for generating an image of the medication units in a selected holder to determine whether a desired number of medication units are present;

packaging apparatus for containing one or more medication units in a package; and

robotics for manipulating a holder to transfer one or more medication units from the container directly to said package.

12. The system of claim 11 wherein each dispenser further comprises a rotating carousel having a plurality of receptacles disposed thereon for receiving respective containers.

13. The system of claim 11 wherein each holder is coupled to an associated container.

14. The apparatus of claim 13 and further comprising control circuitry for controlling said robotics to manipulate said containers to place said desired number of medication units in the associated holder.

15. The apparatus of claim 11 wherein said packaging apparatus comprises:

holding means for holding packaging material; and

apparatus for opening a pocket in said packaging material into which said one or more medication units are transferred.

16. The apparatus of claim 15 wherein said apparatus for forming a pocket comprises first and second arms for applying a vacuum to respective first and second sides of the packaging material, at least one of said first and second arms being movable to displace a portion of said first side from a portion of said second side to form an opening to the pocket.

17. The apparatus of claim 11 wherein said packaging apparatus further comprises a printer for printing patient and medication administration information on said packaging material.

18. Apparatus for dispensing medication in a hospital comprising:

a plurality of containers for holding medication units, said containers having a holding area for temporarily holding one or more medication units;

packaging apparatus for containing one or more medication units in a package; and

an imaging subsystem for detecting the presence of a single medication unit in said holding area;

robotics for manipulating a selected container to transfer medication unit from the container directly to said package.

19. The apparatus of claim 18 wherein said subsystem detects the absense of any medication units in said holding area.

20. The apparatus of claim 19 wherein said subsystem detects the presence of more than a single medication unit in said holding area.

21. The apparatus of claim 19 wherein said subsystem comprises imaging circuitry for generating an image of the contents of said holding area.

22. The apparatus of claim 21 wherein said subsystem further comprises processing circuitry for identifying a cusp in said image and generating a control signal in response thereto.

23. The apparatus of claim 21 wherein said subsystem further comprises processing circuitry for comparing said image with pill-specific information to determine whether a single pill is present in said holding area.

24. The apparatus of claim 23 and further comprising a database coupled to said processing circuitry for storing said pill-specific information.

25. The apparatus of claim 23 wherein said pill-specific information includes pill dimension and shape information.

26. The apparatus of claim 18 wherein said subsystem includes a plurality of imaging circuits to provide images of the holding area from different angles.
