Abstract

1,193,179. Surgical syringes. CARDINAL INSTRUMENT CORP. 19 Dec., 1967, No. 57715/67. Heading A5R. A surgical syringe comprises a cylinder 12 having a discharge orifice 22 at one end, a piston 24 reciprocable in the cylinder, a plunger 26 connected to the piston and extending through the end of the cylinder remote from the orifice, a spring 30 urging the piston towards the orifice and a normally releasable locking means 42 for engaging a recess 34 on the plunger and thus restraining the piston in retracted position against the spring. The locking means comprises a latch 50 which is slidable in a recess 44 which is located in the rear of the cylinder transverse to the plunger axis. The latch has an aperture (52, Fig. 4) through which the plunger passes and is urged outwardly of the recess by springs (60) so that a portion (56) on one side of the latch engages the plunger. Liquid may be drawn into the cylinder through the orifice 22 as the plunger is retracted and discharged when the piston and plunger are released by pressing the latch inwardly of the cylinder. The piston comprises a metal washer 62 and a low friction plastics head 64 secured on the plunger by a nut 66. The periphery of the head is urged outwardly against the cylinder by a resilient ring 70 of wedge-shaped cross-section which is disposed in an annular recess 68 on the forward face of the piston
