Abstract
A connector for medical tubing comprises two interengaging parts (1, 12). As one part is rotated relative to the other, screw-threads cause a tapered projection (13) to mate with a flared bore (6) to provide a fluid-tight seal. Further relative rotation causes the outer bevelled edge of the outer wall (16) of one of the parts to move further forward to sealingly engage the sloping wall (10) of the other part. The projection (13) and outer wall (16) are connected by a flexible membrane 19 to permit this further forward movement. The connector is particularly suited for use in continuous ambulatory peritoneal dialysis.
