Abstract

571,758. Hypodermic syringes. SWIFT, J. E., and WARD, BLENKINSOP, & CO., Ltd. Oct. 28, 1943, No. 17806. [Class 81 (ii)] The body 1 of a hypodermic syringe is provided at one end with a cylinder or socket 12, pivoted to the body at 13 and adapted to receive one end of an ampoule 2 by a longitudinal sliding movement. In the cylinder 12 may be provided a resilient buffer or spring 14 against which the ampoule is pressed so that it may be swung into or out of alignment with the syringe body through longitudinal slots therein, when it is desired to insert or remove the ampoule. The other end of the ampoule is supported for example by a recess in a plug or boss 4, through a hole in which the needle 6 may be passed to puncture the bung 8. The needle is held by a nozzle 5 screwed on to the plug 4 and gripping a protuberance 7 on the needle. In a modification, designed to permit insertion or removal of the ampoule with the needle in position, the recesses in the plug 4 and the cylinder 12 are made deeper, so that the ampoule swings into the syringe body clear of the inner end of the needle.
