ABSTRACT:
An external slot valve for controlling blood flow through the outlet of a shunt of a cardiopulmonary bypass pump wherein a valve seat having a knife edge is fixedly connected to the fixed plate of the bypass pump, and a valve head having a knife edge is pivotally connected to the fixed plate. The valve head is spring biased to the closed position against the valve seat to pinch the shunt extending therethrough. When in the open position, the knife edges provide a slot forming a large orifice for the blood to flow through the outlet of the shunt to diminish the work of the pump and reduce trauma to the blood.
