ABSTRACT:
The present invention provides a medical coupling site which is adapted to be attached directly to a standard male luer lock fitting. The coupling site includes a valve element contained within a tubular retainer. The valve element is formed of a resilient material having greater than that of the retainer, and has a diaphragm including a concave surface with a slit extending diametrically across the surface. The valve element is provided also with biasing means extending inwardly from an inner wall of the valve element into a passage in the valve element such that the biasing means act to bias the slit to a closed position. In a preferred form, the retainer has an outer wall with a maximum outer diameter of approximately 7 mm and an inner wall of the valve element has a minimum inner diameter of approximately 4 mm.
