Abstract
Abstract A medication dispenser station is provided for controlled access to and dispensing of a plurality of different medications. The dispenser station comprises a lockable cabinet containing multiple medication-containing cassettes associated respectively with the different medications and mounted in a vertical stack, with the cassettes having aligned discharge openings cooperatively defining an open discharge chute. Each cassette includes a tray supporting a respective one of a plurality of rotatable carousels having vertically open compartments preloaded with individual doses of a respective one of the different medications. A control unit for the dispenser station responds to appropriate data input using an externally accessible keypad to rotate a selected carousel within its associated tray to sweep the medication within one of the carousel compartments into the discharge chute. The thus-selected medication falls through the chute into an externally accessible receiver to permit removal from the dispenser station for administration to a patient.
