Abstract:
1. A fluid valve comprising: a first input port; one or more additional input ports; an output port substantially axially aligned with the first input port; a valve body, the valve body defining a solely unidirectional flow path from the first input port to the output port, and defining one or more flow paths from the one or more additional input ports to the output port; and an elastomeric portion adapted to allow the one or more flow paths from the one or more additional input ports to the output port to be open when there is no fluid flow through the valve body, wherein, when a liquid applies a pressure to the first input port that equals or is greater than a defined pressure, the liquid flows in the solely unidirectional flow path from the first input port to the output port, and any flow path from the one or more additional input ports to the output port is blocked by the elastomeric portion of the valve, wherein the defined pressure is a function of at least one physical property of at least one valve component, and wherein the liquid is a contrast medium.
