<p>Medical intravenous administration connectors include a first coupling member (12) having a female luer (22), a valve member having a substantially rigid stem (14) and a substantially resilient body (16) with a sealing surface, and a second coupling member (18) having a fluid coupling extending from one end and an internal valve member support. The valve stem (14) extends into the female luer, and the valve body (16) biases the sealing surface against an annular ring (27) in the first coupling member thereby blocking fluid communication. Vanes are provided in the second coupling member on which the resilient body of the valve sits to center the valve member. The valve may be opened for fluid flow through the assembly by coupling a male luer to the female luer, or by pressure actuation.</p> |
