SYRINGE Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: injection syringe has body and rod positioned in it. One-shot insert in the form of bellows with injector is arranged between rod and body. Chamber for injection compound is formed by injector displacement relative to bellows. In initial position, connecting member prevents bellows from straightening which indicates that insert was not used earlier. Locking devices in the shape of profiled projections and recesses on rod and injector, as well as on body enable prompt assembly and disassembly of syringe. Body and rod are syringe parts which may be used many times, provided corresponding sterilization is carried out. Insert is one-shot element. EFFECT: more effective construction. 6 dwg
