ABSTRACT:
Either a pyrotechnic-powered needleless injector or (with spacer adapters) a conventional syringe is held in firmly abutting alignment with a dispensing orifice of a special storage vial. A flexible perforated seal forms a plug in the dispensing orifice, opens under liquid pressure to dispense medicament from vial to injector, and seals around the dispensing path between vial and injector against loss of the medicament. The liquid medicament is forced through the orifice under the action of a plunger forming one wall of the vial. The plunger in turn is driven by a micrometer-type screw whcih is calibrated in terms of dispensed volume.
