ABSTRACT:
A valved adapter for connecting a fluid handling device to a medical device includes a body with a longitudinal axis having a proximal end, a distal end and a chamber therewithin. The body includes a passageway from the proximal end to the distal end and has a valve contained within the chamber in a normally closed position that is operative to an open position. The valve also includes a hollow tube having a bore therethrough with a closed proximal end mounted coaxially within the passageway and extending from the proximal end to the distal end of the body. The tube has at least one side port opening into its bore that is located a distance distally from the closed end. The valve also includes a resilient member located coaxially about the tube that is biased to occlude the side port in the valve's normally closed position. The valve is opened by a distal movement of the resilient member to overcome the bias and to uncover the side port thereby allowing a fluid flow into the tube and through the valve.
