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.

[ What is claimed is:] [1.] A valved adapter for connecting a fluid handling device to a medical device comprising:a body with a longitudinal axis having a proximal end, a distal end and a chamber extending therebetween;a valve contained within said chamber in a normally closed position but being operative to an open position, said valve comprising a hollow tube having a bore therethrough with a closed proximal end, said tube being mounted coaxially within said chamber extending from adjacent said proximal end of said body to adjacent said distal end, said tube having at least one side port opening into said bore located a distance distally from said closed end, said valve further including a resilient member located coaxially about said tube and biased to occlude said side port in said normally closed position wherein said resilient member has a proximal end defining an opening therein with a diameter sufficient to allow said tube to pass therethrough, said valve being operative to be opened by a distal movement of said resilient member to overcome said bias and to uncover said side port thereby allowing a fluid flow through said valve;wherein said chamber includes an inwardly projecting distal shoulder, said resilient member being compressible between a mounted fluid handling device and said distal shoulder thereby providing a bias for said valve to said normally closed position and wherein said bias is provided by a coil spring located distally to said resilient member coaxially about said tube and compressible between said resilient member and said shoulder.
