Filed: 2004-05-05
Abstract: A self-sealing male connector (60) having a body (62), a resilient boot (64) mounted over the body, and a male thread hub. The body is formed with an elongate post (78) that extends to the distal end. The body includes a fluid flow lumen (116) extending from its proximal end (70) to its distal end (114) At its proximal end, the body may be formed as a female Luer connector, or may be directly connected to tubing, or other arrangements. The internal fluid flow lumen extends through the post to its distal end. The body includes a first groove in which is mounted the boot. In a second groove is mounted the thread cuff. The thread cuff is used to a female connector and through thread action, draw in into engagement with the post. As the female connector (194) is further engaged with the sealed male connector, the post protrudes through the boot and into fluid communication with the female fluid flow passage thus establishing a flow path through both connectors. The boot forms a seal with the female connector when engaged and returns to seal the male connector post and fluid flow passage within disconnected from the female connector.
