Abstract
A positive pressure one way medical valve contains an inlet (), outlet (), an internal flow path between the inlet and the outlet and a plunger () movable between a retraced sealing position, where backflow is reduced or prevented and an extended open position, where fluid can flow from the inlet to the outlet. The plunger is moved from the retraced to the extended position by insertion of a tip onto the inlet (). A variable volume chamber () is defined partially by an elastomeric member () that is stretched, when plunger is in the extended position and reduced, when the plunger is in the retraced position so to increase or decrease the volume of the chamber respectively. A valve (), which is movable between open and closed positions by the presence or absence of fluid passing through the inlet, immediately seals the flow pathway before the plunger is retraced.
