Abstract

836,279. Hypodermic syringes. AMERICAN HOME PRODUCTS CORPORATION. Jan. 20, 1958 [March 26, 1957], No. 1818/58. Class 81 (2). A push-rod for a disposable syringe has the attachment means for connecting it to the piston stopper, flexibly mounted on it so as to permit slight lateral movement of the push-rod without displacing the stopper. Thus, in the form shown the push-rod 22 is made tubular and the screwed portion 23, for insertion into the threaded hole 24 of the stopper 25, is carried on a thin diaphragm 26, which may be divided to form a number of spokes. The diaphragm may be formed in one piece with the push-rod, if this is made of suitable synthetic resin, or it may be of metal moulded into the material of the rod. The connection between the push-rod and the stopper may be with threaded parts or a selftapping screw may be used in one part. The push-rod, if hollow, may serve as a cover for the needle prior to use, being retained in that position by a screwed or push-on connection. Specification 754,835 is referred to.
