ABSTRACT:
A valved adapter for connecting a fluid handling device to a medical device includes a body with a longitudinal axis and having a female luer fitting at a proximal end, a distal end and a passageway therethrough. The passageway has a chamber intermediate the proximal end and the distal end containing a valve having a normally closed position but operative to an open position. The valve includes a relatively elongate resilient member with a proximal end and an axis substantially coaxial to the longitudinal axis of the adapter. The valve further includes a pusher disposed at the proximal end of the elongate resilient member. The pusher includes a telescopic portion having an extended position and a collapsed position. The telescopic portion is biased to the extended position.
