Adapter for mounting a fluid handling device on a catheter tubing

An adapter for attaching a fluid handling device to a catheter tubing includes a body with a proximal end, a distal end and a passageway therethrough. The body has a proximal end that has a fitting for attaching a fluid handling device. The distal end of the body includes an elongate receptacle with an inside surface that has least one engagement lug. There is an elongate resilient member disposed within the receptacle with a first end and a second end and a coaxial passage therethrough. The passage has an inside diameter to accept and form a releasable substantially fluid tight connection to a preselected catheter tube. The resilient member has a first conjugate engagement to the receptacle engagement lug at the first end and a second engagement at the second end. The adapter also has a latch member disposed over the receptacle to contain the resilient member that has a distal axial access port therein to receive the catheter tube into the resilient member passage. The latch member has an inside surface with at least one second engagement lug for engaging the second end engagement of the resilient member. The latch member is disposed for rotatable movement with respect to the body between an insertion position and a latched position. The rotation of the latch member with respect to the body rotationally displaces the first end of the resilient member with respect to the second end of the resilient member, thereby decreasing the inside diameter of the resilient member passage.
