Abstract

1,262,780. Hypodermic needles. INJEKTA KLINGENTHAL VEB. 29 Oct., 1969, No. 53002/69. Heading A5R. In attaching a plastics hub 4 to a hypodermic needle 1 softening chemicals are applied to a knurled portion 2 of the needle, remote from the point, from a proportioning device, before the needle is totally inserted into the bore 3 of the hub. The needle is then pushed through the hub so that the knurled portion engages in the bore. The chemicals soften the plastics hub deforming it, so that after evaporation of the chemicals the needle and hub are non-displaceably engaged.
