Abstract

712,859. Hypodermic needles. OGLE, R. W. Feb. 14, 1952 [July 9, 1951], No. 3977/52. Class 81(2) A method of imbedding a hollow needle 14 in synthetic resin comprises mounting the needle 14 on a mandrel 15 a portion of which extends from within the needle 14, driving the mandrel 15 in the synthetic resin, driving the needle 14 with the mandrel 15 within the opening formed and removing the mandrel 15 from the needle 14. The extending portion of the mandrel 15 has a sharpened end 16 which is driven into a post 13 of a syringe 10 made of polyethylene. The needle 14 may be driven right through the post 13 or part-way through the post 13 connection between the interior of the syringe 10 and the hollow needle 14 being made by a passage formed by the mandrel 15. The needle openirig. is formed by the separation of the synthetic resin so that the needle is held in its final position by elastic tension of the synthetic resin. Specification 712,860 is referred to.
