Medicine dispensing device
First Claim
1. A medicine dispensing device, comprising:
- a housing having a slotted region, a front end including a front end opening, a rear end including a rear end opening, at least a first threaded portion provided on an inside surface of said housing in the vicinity of said rear end opening, a dosage ampoule fitting and a discharge conduit provided in the vicinity of said front end for connection with a dosage ampoule, said housing being adapted to receive said ampoule therein;
a hollow screw-threaded device also for receiving said ampoule therein, said screw-threaded device being received by said rear end opening of said housing, said screw-threaded device including on at least partially threaded outer surface engaging said first threaded, portion in the vicinity of said rear end of said housing for securing said ampoule within said housing; and
a medicine discharge and metering device being received within said hollow screw-threaded device and being movable in a direction of a longitudinal axis thereof, said medicine discharge and metering device metering and discharging contents of said ampoule; and
wherein subsequent to an administration of a desired dosage of the contents of said ampoule, said medicine discharge and metering device enables said ampoule to move in the direction of the longitudinal axis of said housing and rearwardly in said housing to an extent sufficient to release said ampoule from engagement with said ampoule fitting, thereby allowing said ampoule, said screw threaded device, and said discharge and metering device to swing outwardly from said housing through said slotted housing, whereby said screw-threaded device is disengaged from said at least one threaded portion, thereby enabling said screw-threaded device and said discharging and metering device to move rearwardly and to return to a starting position within said housing where said screw-threaded device is able receive a new ampoule through said slotted housing.

Abstract
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.
