Abstract

1448108 Syringes MPL Inc 19 Nov 1973 [1 Dec 1972] 53522/73 Heading F1R [Also in Division A5 A rubber hour-glass-shaped plug 25 is removably elastically located in a seat 23b in a piston 23 which slides in a cylindrical tubular glass or plastics barrel 13. The barrel 13 of a syringe 11 has a rubber or plastics portion 17a, into which is threaded a handle 17b, the piston 23, a finger grip 13a and a polypropylene or nylon nose 15 with a flange 15h threaded at 15t for attaching a Luer-hubbed needle after removing cover 41 which may be heat-sealed to the nose at 16. When piston 17a is moved forward a hydraulic ram effect moves piston 23 forward so that plug 25 contacts post 15n, air now being expelled only through slots 15s, instead of axially through the post, to bores 15nb and 15ab. Plug 25 is expelled from seat 23b into chamber 27 which is larger than the plug to allow liquid to pass through the bore vacated by the plug. A rear wall 29 of piston 23 having lips 23i and nodules 23j retains plug 25, the latter may have channels or ribs 25a' to allow fluid to pass it when it is against the forward interior wall of chamber 27 which wall may itself be grooved. The rear face of plug 25 may be channelled and body 23 be channelled at 23w' between lips 23i. When relaxed, plug 25 is of a complementary size to seat 23b, inserting piston 23 into barrel 13 compresses the seat on to the plug. Alternative nose embodiments are a nose integral with the barrel, an unthreaded nose for connecting a Luer hub and an oral-nippled nose.
