Adaptor for hypodermic syringe

Claim 1

In combination, a hypodermic syringe means having an axially extending body with an integral centrally located hub at one end providing a discharge fitting with an axially extending discharge duct extending through the fitting, said syringe being capable of hypodermic injection when a straight axially extending hypodermic needle is mounted on said discharge fitting, a hypodermic needle of substantially uniform cross section and bent to provide an inlet section at one end coaxial with said discharge fitting, an outlet section at the other end laterally offset from and generally parallel to the inlet section and terminating in an insertion point for insertion into a vein substantially parallel to the vein to avoid penetration of the side walls of the vein, an intermediate section transverse to the inlet and outlet sections, a bend connecting the inlet section to the intermediate section, and another bend connecting the intermediate section to the outlet section, and structure for increasing the rigidity of said needle when mounted on said discharge fitting, said structure comprising an injection molded thermoplastic body molded about and embedding the inlet, intermediate and outlet sections and the bends of said needle with the insertion point exposed at one end of the body, said body having a fitting complementary to said discharge fitting integral with the other end of the body and surrounding the inlet end of the needle rigidly mounting the needle on said discharge fitting and connecting said discharge duct to the inlet end of the needle, said body anchoring and imparting rigidity to the needle and eliminating deflection which could interfere with the accuracy of insertion of the needle.
