Abstract
1430829 Making needle assemblies BAXTER LABORATORIES Inc 9 Aug 1973 [17 Aug 1972] 37723/73 Heading B3A [Also in Division A5] A method of forming a cutting tip on a needle assembly having an elongate cannula 14 and a needle 18 extending through the cannula comprises introducing and moving the needle within the cannula to an operative position, reducing the diameter of the cannula along a part of its length into contact with the needle to grip the latter, and simultaneously forming bevels on the tips of the cannula and needle, so that both tips lie within a common plane. The cannula diameter may be reduced either by drawing or by a swaging operation wherein dies are rotated about the cannula and strike it at intervals as the assembly is slowly advanced into the swaging apparatus. The needle is held frictionally in the cannula towards the tip of the assembly, but after the bevels have been formed either by shearing or grinding it is free to slide within the cannula. A further bevel having a length H may also be provided to form a point (22), Fig. 5 (not shown). The needle assembly is inserted in metal or plastics support body (12), Fig. 1a (not shown), and secured by stacking or an adhesive. Owing to the close fit of the needle within the cannula the problem of skin or tissue coring is largely overcome.
