Abstract
1380873 Syringes AMERICAN HOSPITAL SUPPLY CORP 19 March 1973 13126/73 Heading A5R A syringe comprises a tubular barrel 16, a plunger 17 and an elastic member 18 having an anchor portion (33) engaging pointed projections 23 extending rearwardly from the rear end of the barrel to hold the anchor portion against longitudinal movement, and an element 34 engaged by the plunger for longitudinal movement therewith, the member being stretchable towards the front end of the barrel as the plunger is moved into the barrel. The member comprises three bands 35 joined to an annular rear wall 42 from which extends a cylindrical outer wall 43 gripping the outside of the syringe barrel. An annular flange 41 on element 34 engages a groove 31 in plunger 17 and ribs 39, 40 seal against the barrel. The projections 23 are pyramidal teeth which engage the anchor portion (33) at the junction of walls 42, 43. The barrel and plunger may be moulded from plastics material, the plunger 17 comprising discs 27, 28 connected by four intersecting planar ribs 30.
