Abstract:
A medicament-dispensing system includes a cartridge for housing and actuating an accordion-like vial-dispenser for dispensing a calibrated amount of medicament by means of a single actuation motion which sequentially loads the vial-dispenser and dispenses the loaded medicament. The vial-dispenser has a front bellows portion, a rear bellows portion, an internal piston mechanism, a medicament storage chamber and a dosage cavity. The cartridge has a trigger mechanism which acts in concert with a notched lever and a wedge-shaped arm internally located in the cartridge to sequentially load the dosage cavity with medicament and discharge it. Depression of the trigger mechanism simultaneously extends, by means of the notched lever, the front bellows portion and compresses the rear bellows portion to load the dosage cavity with medicament. Once the notched lever has extended the front bellows portion a predetermined distance, the notched lever is disengaged from the front bellows portion by the wedge-shaped arm extending from the rear wall of the housing, thereby releasing the front and rear bellows portions, along with the internal piston mechanism, to return to original position and force the medicament from the dosage cavity via a nozzle of the vial-dispenser.

A pump for delivering a fluid contained in an elastic phial includes a pump body and a movable piston fitted inside the pump body. The front end of the pump body is located on a fluid-outlet side, and the front end includes an outlet orifice (11) sealed off by an elastic membrane (24). The outlet orifice is connected to a pump duct (18) inside the pump body, and the pump duct 18 is in turn connected to a fluid-inlet orifice (15). An end (2) of the movable piston is hermetically fitted within the pump duct (18) with slight friction, and the displacement of the end (2) of the piston relative to the portion of the pump body between the inlet orifice (15) and the a stop position (16) near the outlet orifice (11) determines the quantity of fluid expelled from the pump body. The inlet orifice allows a predetermined quantity of fluid to be trapped at the end of the pump duct (18) before being expelled through the outlet orifice (11). With the exception of the front end of the pump body, the pump body and the movable piston are totally enveloped by the elastic phial.
