Rotatable bubble-free connector

摘要

A connector for connecting two catheters and permitting the catheters to rotate relatively, the connector having a collar, a hub and a rotator, the hub and the rotator having an O-Ring therebetween. The rotator overlays the hub and has an internal surface that has a shape that is contoured to the shape of the O-Ring to make a seal therebetween. The hub has a surface at an end thereof with a projection thereon that biases the O-Ring into a sealing contact with the internal contoured surface of the rotator. The collar prohibits the hub from withdrawing from its overlaid position within the rotator by overhanging a surface extending radially from the hub. The hub receives a catheter, at the end opposite its contact with the O-Ring, the catheter wedging within the hub. The rotator received a catheter by an end having a luer lock with a common longitudinal axis about which they are all preferably symmetrical. Each component, including the O-Ring is preferably concentrically aligned.
