Abstract
A hypodermic syringe of the automatic, or self-aspirating, type for use in combination with cartridge ampoules closed at the lower end by a rubber diaphragm pierceable by a double-ended hypodermic needle and closed at the upper end by a slidable rubber piston comprises a combination of a syringe holder unit and a self-aspirating assembly so-adapted to generate aspirating conditions in the ampoule by the slight backward displacement of the rubber piston.
