Abstract

708,707. Hypodermic syringes. STERLING DRUG Inc. Oct. 27, 1952 [Nov. 1, 1951], No. 26904/52. Class 81(2) A disposable hypodermic syringe comprises a synthetic resin one-piece ampoule 10 having an open end 12 in which a plunger 20 is located, a closed end in the form of a diaphragm 18 and an open-ended tube 16 extending beyond the' diaphragm. A doubleended needle 24 is firmly mounted in a slidable needle guide 22 and placed with its inner end 26 adjacent to the diaphragm 18, the needle then being enclosed by a tubular cover 30 which is a sliding fit within the tube 16. When the syringe is required for use, the cover 30 is first pressed inwards so as to move the guide 22 and needle 24 downwards, thus causing the needle to pierce the diaphragm, the cover is then withdrawn and its end 34, which is threaded, is screwed into a recess 38 in a plunger 20 to expel the contents.
