Abstract

1441387 Hypodermic syringes P I PARKINSON 4 Sept 1973 [11 Sept 1972] 42154/72 Heading A5R A hypodermic syringe is provided with a resilient latch 23 operative between the plunger 11 and barrel 10 penmitting the. operator to draw back the plunger to a predetermined extent, the latch being formed by an arm of resilient plastics material bonded at one end to a rib 18 of the plunger and cranked outwardly at its forward end 22. The forwardly directed surface of end 22 abuts the rear end of the barrel when the plunger is withdrawn therefrom. The plunger stem 16 is of cruciform longitudinal cross-section with intermediate ribs 18, one or more of which may carry a latch member 23.
