CONNECTOR ASSEMBLY FOR STERILE CONNECTION TO CONTAINERS Russian patent published in 2014 - IPC A61M5/162 

FIELD: medicine.

SUBSTANCE: invention refers to medical devices, particularly to devices for drug administration into the body, and is applicable for connecting the device to a solution container by puncturing, e.g. a rubber stopper of a glass container. A connector assembly for the sterile connection to containers comprises a protective detachable cap, an adapter needle and a case inside the protective cap and gapped from its inside and the needle surface, and detachably connected to the needle at its base from the side of the adapter. The assembly is additionally provided with an O-ring at the base of the needle. The case is connected to the needle using the O-ring and made of a rigid polymer film. The film is at least two-layered. A coefficient of sliding friction of the external layer exceeds a coefficient of sliding friction of the internal layer.

EFFECT: invention provides reducing a risk of the microbial contamination of transfused media if connected to various systems or devices by improving the reliability of the needle connection to the transfusion medium or solution container, and providing the higher tightness of the connector assembly.
