ABSTRACT:
A luer hub connector comprises a hub having a cylindrical bore extending there through. The hub is adapted to have a luer device connected at one end. A cap having a hollow nozzle extending therefrom is formed at the other end of the hub. A cylindrical spring-like member is positioned within the bore in the hub, and a septum membrane closes the end of the spring-like member. A sliding, hollow sleeve member is received in the bore of the hub member, with a hollow nozzle extending from the sleeve member into the bore of the spring-like member. When a luer device is threaded onto the end of the hub, it contacts and drives the sleeve member towards the septum. The end of the hollow nozzle is pushed through the septum, and the spring-like member is also compressed. When the luer device is removed, the spring-like member pushes the sleeve member back, and the hollow nozzle withdraws out of contact with the septum. The septum then closes and seals.
