Abstract

787,963. Hypodermic syringes. FARBWERKE HOECHST AKT. - GES. VORM. MEISTER, LUCIUS & BRUNING. Sept. 1, 1955 [Sept. 1, 1954], No. 25192/55. Class 81 (2). In an ampoule syringe the plunger rod 2, having curved claws 4, is surrounded by a non- rotatable sleeve 5 carrying a spiked member 6 so that, by pressure on the stopper 8, the spikes hold the stopper against rotation while the claws are engaged with it by rotation of the rod 2. After the stopper has been so gripped the syringe may be used for aspiration.
