Abstract

The invention relates to an anti-contagion syringe device which allows the venting of air and retraction of the needle. Said device consists of a body (1) with a head (2) containing teeth (19), and a piston (10) with a base (22) which has a ring (16) and a heel (18). The piston (10) acts on the lugs (20) which free the part (5), which in turn makes the tip (7) retract by means of a spring (8). At the same time, the heel (18) locks the piston (10) in the rabbet (21). The device of the invention is designed for the medical profession and for all those using syringes, with a view to avoiding cases of contagion.
