Luer hub connector

A luer hub connector for use with an injection-device, the luer hub connector configured to automatically close when the injection device is decoupled from the luer hub connector to control the backward flow of blood and body fluids through the connector, the luer hub connector comprising;

• a body member having a proximal end and distal end;
• a cylindrical bore extending along the length of the body member from a proximal end to a distal end thereof;
• a one-way septum valve positioned within the cylindrical bore so as to selectively control the flow of fluids through the cylindrical bore, the one-way septum valve comprising a longitudinal cylinder and having a proximal end, a distal end, an outside diameter, an inside diameter, and a plurality of annuluses integrally formed with the longitudinal cylinder, the plurality of annuluses arranged in a repeating, wave-like pattern where each annulus of the plurality of annuluses extends outwardly from the outside diameter of the longitudinal cylinder and the inside diameter of the longitudinal cylinder is substantially constant along a longitudinal length of the cylinder which spans between at least two annuluses, and wherein the annuluses are configured to compress against each other when a compressive force is applied to the septum valve, the compression of the annuluses thereby providing a resilient biasing force in the opposite direction of the compressive force, and wherein one or more annuluses are positioned in the proximal end of the one-way septum valve, wherein a first annulus is positioned at the distal end of the one-way septum valve, the first annulus configured to contact a surface at the distal end of the cylindrical bore, thereby biasing the septum valve in the closed position, and wherein a septum is positioned between the proximal end and the distal end such that the septum can be opened by interaction with a secondary member which exerts a compressive or dialatory force on the one-way septum valve and the septum will close in response to removal of the compressive or dialatory force on the one-way septum valve;
• and
• a cylindrical sliding sleeve member slidably positioned within the cylindrical bore adjacent a luer coupling on the proximal end of the body member.
