ABSTRACT:
A needleless IV quick-connect/disconnect assembly includes a first cylindrical member having a female luer, a resilient valve member having stem, a sealing surface, and a base, and a second cylindrical member having a fluid coupling extending from one end and an internal valve member support. The cylindrical members are sized so that the first cylindrical member fits snugly inside the second cylindrical member. A pair of radial ramped protrusions extend from the outer surface of the first cylindrical member and a pair of radial openings are provided in the second cylindrical member. In assembly, with the valve member stem in the female luer, the first cylindrical member is inserted into the second cylindrical member until the radial ramped protrusions engage the radial openings and the valve member base is engaged by the valve member support. When assembled, the valve stem extends into the female luer from inside the first cylindrical member and the valve member base biases the sealing ring against an annular ring in the first cylindrical member thereby blocking fluid communication. Coupling a male luer to the female luer of the assembly opens the valve for fluid flow through the assembly, while uncoupling the male luer from the female luer closes the valve and prevents fluid flow therethrough.
