Abstract

The syringe, with automatic and secure retraction of the needle after the injection, with absolutely no possibility of extending the needle either forwards or backwards, consists, in one version, of a hollow plunger enclosure 2 having at the forward end a closing member 5, 6 which is retracted at the end of the injection stroke by the force of the tang 16 of the needle 12 produced by the action of the cylindrical helical spring 26 which is precompressed inside the chamber 27 of a smaller-diameter forward and backward continuation 20 of the skirt 1 fixed at the forward and backward ends between the closed end 28 of this continuation and the tang of the needle: an elastic diaphragm 14 that forms part of a seal with two arms 14'-17, 15 acts as a limit to the retraction of the tang and of the needle until the end of the injection operation, when it is cut by the fixed punch 25' by the action of the forward end of the plunger enclosure 2; the syringe is used principally for medical and veterinary purposes.
