MEDICAL CONNECTOR (VERSIONS) AND METHOD OF EXPLOITATION THEREOF Russian patent published in 2014 - IPC A61M25/18 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, includes a medical connector (versions) and a method of the connector exploitation, and is intended for supply of a liquid by means of the medical connector, which has a low volume of filling and a low direct displacement when disconnected. The connector contains a valve case, a valve plug, a membrane and a valve insert. The valve case is provided with an input branch piece, an output branch piece, an internal wall and one or several channels in the internal wall, which form a current line from the input branch piece to the output branch piece. The valve plug is intended for sealing the input branch piece when the connector is in an inactive state and closes the line of current through the connector. The membrane is placed in the valve case. The valve insert is located in the valve case and contains a cup, sealed with the membrane with formation of an internal volume. The valve insert contains a rod, extending into the output branch piece and configured in such a way that a transverse section of the output branch piece flow is equivalent to the transverse section of the current line flow, formed by one or several channels in the internal wall of the valve case. When the connector is put in action, the valve plug deforms the membrane into the internal volume, and unseals the input branch piece and opens the line of current through the connector.

EFFECT: inventions make it possible to provide characteristics of a direct liquid displacement after putting in action the connector, which has the low volume of filling due to construction of the valve plug, the valve insert and the membrane.
