Abstract
An adapter of the present invention useful for attaching a fluid handling device to a catheter includes a body having a proximal end, a distal end and an open passageway therethrough. The passageway includes a seat to receive the catheter and a cavity distal to the catheter seat. There is a gasket disposed in the cavity to form a substantially fluid tight seal about the catheter when the catheter is positioned on the catheter seat. The adapter further includes a retainer, disposed on the distal end of the body over the gasket with an opening therethrough that is substantially aligned with the passageway. The opening is sufficient to allow the catheter to pass through into the passageway to engage the gasket and the catheter seat. The retainer has a plurality of flexible projections into the opening that are sized and shaped to engage the catheter and be proximally deflected by the placement of the catheter on the catheter seat. There is a rotatable collar disposed over the retainer on the proximal end of the body, with an open port therethrough that is substantially aligned with the passageway to allow placement of the catheter into the passageway. The collar has a plurality of pro…
