PCT No. PCT/SE93/00015 Sec. 371 Date Aug. 30, 1993 Sec. 102(e) Date Aug. 30, 1993 PCT Filed Jan. 14, 1993 PCT Pub. No. WO93/14799 PCT Pub. Date Aug. 5, 1993.A medicine dispensing device including a slotted housing, a front end, a rear end, at least one threaded portion in the vicinity of the rear end, a dosage ampoule fitting in the vicinity of the front end and a discharge conduit for connection with a discharge ampoule. A hollow screw-threaded device receives the ampoule therein. The screw-threaded device is received by the rear end of the housing. The screw-threaded device includes an exterior surface provided with a threaded surface engaging the at least one threaded portion for securing the ampoule within the housing. A medicine discharge and metering device for metering and discharging the contents of the ampoule is received within the screw-threaded device and is movable in a direction of a longitudinal axis thereof. Subsequent to administering a dosage from the ampoule, the medicine discharge and metering device enables the ampoule to move rearwardly in a direction of a longitudinal axis of the housing to an extent sufficient to release the ampoule from engagement with the ampoule fitting. The ampoule, the screw-threaded device, and the discharge and metering device are thereby permitted to swing outwardly through the slotted housing, whereby the screw-threaded device is disengaged from the at least one threaded portion, thereby enabling the screw-threaded device and the discharging and metering device to move rearwardly and to return to a starting position within the housing where the screw-threaded device can receive a new ampoule through the housing. |
