Abstract

The system includes a medication-receiving assembly which collects medications automatically dispensed from storage assemblies therefor and a transport assembly for moving the collected medications to a loading assembly, wherein the loading assembly is arranged and positioned so that the medications move by gravity action from an upper end thereof, past a pair of opposing, angled deflectors which are individually controllable and which guide the medications into selected portions of a medication bin in a medication cart, which accommodates medications for a large number of patients, such as all the patients on a hospital ward. Supplemental medications not present in the storage assemblies can be provided with a hand-loaded supplemental doses assembly. The medication cart may then be moved directly to the ward and the bedside of the individual patients in turn.

Claims

1. A system for handling preselected, packaged medications dispensed from a plurality of storage assemblies, comprising:

a medication-receiving assembly for collecting medications which have been dispensed from a storage assembly therefor; and

means for transporting the collected medications to a medication loading assembly, the transporting means including an endless conveyor having a first portion and an upwardly directed second portion, wherein the first portion is arranged such that a plurality of medication-storing assemblies can be brought adjacent the first portion, permitting medications to be dispensed from the medication-storing assemblies directly onto the conveyor, the conveyor including a plurality of elements along the length thereof for spacing dispensed medications and means for moving the conveyor so as to transport medications thereon to the medication loading assembly, wherein the medication loading assembly is positioned relative to the conveyor and is configured so that the packaged medications move by gravity out of a lower end of the loading assembly to a selected medication receptacle in a medication cart having a plurality of medication receptacles, the lower end of the medication loading assembly being configured so as to guide the packaged medications directly into a selected portion of the selected medication receptacle.

2. A system of claim 1, wherein the medication receptacle is a medication bin.

3. A system of claim 2, including a pair of opposing deflectors at the lower end of the loading assembly for guiding the medications into the medication receptacle.

4. A system of claim 3, including means for controlling the position of the deflectors so that more than one portion in a medication bin can be filled with medications without moving the medication cart.

5. A system of claim 4, including flexible, flat portions extending from free ends of the deflectors to ensure that medications fall into the selected portion of the medication bin.

6. A system of claim 3, wherein the deflector means includes a pair of opposed diverter arms which are mounted to move toward and away from each other, increasing/decreasing an exit opening at a lower end of the loading assembly.

7. A system of claim 6, including a removable lid overlying the opposed diverter arms which can be moved so as to permit convenient access to the loading assembly in the diverter arms area.

8. A system of claim 1, wherein said selected portion is associated with a particular patient and said packaged medications have been prescribed for said particular patient.

9. A system of claim 1, wherein said selected portion is medication-specific.

10. A system of claim 9, wherein the incline is within the range of 35°

-55°

.

11. A system of claim 9, wherein the incline is at such an angle that the packaged medications move freely by gravity out of the loading assembly into the medication cart.

12. A system of claim 1, wherein the transporting means is inclined upwardly between the receiving assembly and the loading assembly.

13. A system of claim 1, wherein the receiving assembly includes a funnel arrangement down which the received medications move by gravity onto the transporting means.

14. A system of claim 1, including a supplemental doses assembly positioned adjacent the loading assembly for adding selected medications not available from the storage assemblies.

15. A system of claim 14, wherein the supplemental doses assembly includes a plurality of compartments capable of receiving medications, each compartment having a controllable compartment door, which when activated opens so that any medication therein moves into the loading assembly.

16. A system of claim 15, wherein the compartment doors are controllable such that only those compartment doors which contain supplemental medications for a particular patient are opened in conjunction with medications for said patient being dispensed from the medications vaults, so that the supplemental medications and the dispensed medications are directed together into the medication bin.

17. A system of claim 1, including a supplemental doses assembly located above the first portion of the conveyor.

18. A system for handling preselected, packaged medications dispensed from a plurality of storage assemblies, comprising:

a medication-receiving assembly for collecting medications which have been dispensed from a storage assembly therefor; and

means for transporting the collected medications to a medication-loading assembly, the transporting means being in the form of an upwardly inclined tube, and including a pusher element which has an outline slightly smaller than the tube, the transporting means further including a powered member which moves between opposing ends of the tube for moving medications which have fallen into the tube at lone end thereof to an opposing end of the tube, where they move into the loading assembly, wherein the medication-loading assembly is positioned relative to the conveyor and is configured so that the packaged medications move by gravity out of a lower end of the loading assembly to a selected medication receptacle in a medication cart having a plurality of medication receptacles, the lower end of the medication loading assembly being configured so as to guide the packaged medications directly into a selected portion of the selected medication receptacle.
