Abstract

A disposable, single use syringe comprises a hollow body (42), a retractable needle assembly (70) positioned in the hollow body, and a plunger assembly (100) including at least one guide track (128) between its ends. A retraction member (160) is releasably secured to one end of the frame and a catch member(105, 190), including a catch element (124), is positioned with a guide configured to travel in the plunger frame guide track. An elastic member (164) extends between the retraction member and the catch member. A retention assembly (120) depends from the opposite end of the plunger frame and is configured to receive and secure the catch element (124) and thereby tension the elastic member. The needle assembly and the retraction member have complimentary mating members (51), whereby the tension on the elastic member is released and the injection means is drawn into the hollow body after the needle assembly and the retraction member mate._ipc
