<p>An automatic fluid control having a first (14) and second (18) tube member and a slidable valve element (20) capable of moving from a sealed closed position to an open position permitting fluid passage therethrough. In a preferred first embodiment, the elastomeric valve element is slidingly received with a passageway (28) in the first tube. The valve element has a flange portion containing a plurality of slits (82) in the first tube. The valve element has a flange portion containing a plurality of slits (82) that, when inverted and stretched, permit fluid to pass therethrough, but when closed, are in contact with the inner wall of the first tube and prevents fluid from passing therethrough. The valve element also can have a rigid plug (90) attached within an opening in the top surface to present a preferably non-deformable contact point for a male luer tip (112) which, when pressed downward on the valve element, breaks a seal between the valve element and the first tube inner wall.</p> |
