PRE-FILLED SYRINGE STEAM-STERILISED IN AUTOCLAVE Russian patent published in 2009 - IPC A61M5/178 A61M5/28 A61L2/07 A61L2/20 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to a syringe, particularly to a syringe designed as pre-filled and thereafter steam-sterilised in an autoclave, and also to a kit containing a package and said syringe in presented package. The syringe comprises a body, a rod, an internal chamber and carrier. The body has a cylindrical lateral wall and an open upper downstream end with an internal ring collar nearby, and lower downstream end closed with a transverse apertured wall. The rod forms a plunger arranged on the same end with a piston that forms a seal and has at least two sealing rings that fix the borders of at least one annular chamber. The rod is introduced inside of the body while travelling there along. The internal chamber is designed to be filled at least partially. The borders of the chamber borders are limited by the piston and a crosswall of the body. Carrier is formed in the body of the syringe and ensures communication of the annular chamber, or the piston chambers with area outside of the body, or with the internal chamber of the body as the piston is inside of the body and adjoins the ring collar. The kit comprises actually microorganism-impermeable at least partially steam permeable package and said syringe. And said syringe is enclosed in said package, and its internal chamber is filled with contents at least partially.

EFFECT: invention allows for damp heat sterilisation of areas between rings of the syringe piston and as a result considerably reduces amount of heat required for sterilisation.
