VALVED MALE LUER CONNECTOR HAVING SEQUENTIAL VALVE TIMING

摘要

A male Luer connector (200) that attaches to a female Luer connector to open a
medical fluid flow channel between said connectors. The male connector has two
internal valves (206, 208) and a vacuum-generating structure (212, 210). The
two valves and the vacuum-~ generating structure are configured to draw back
into the male connector any fluid residing on the interface between the
connectors during their disengagement and to then seal the distal tip of the
male connector. Both valves are opened/closed by a movable actuator plug (224)
by contact with the front surface of the female connector. A resilient member
(210) biases the male valves to the closed position and includes a variable
internal volume (212) that creates the vacuum upon disengagement of the
connectors. The male valves are timed to a particular sequence with the
closing of an internal female connector valve so that the vacuum generated by
the male connector will have the most fluid drawback effect.
