ABSTRACT:
A pump for moving fluid, as blood, having a cylindrical body defining a chamber. A piston movably located in the chamber carries a one-way valve movable to an open position to allow fluid to flow into the chamber and movable to a closed position to pump fluid from the chamber. One or more solenoids operate to reciprocate the piston in the chamber to pump fluid from the chamber. A one-way valve in an inlet passage to the chamber functions to allow the flow of fluid into the chamber and restrict reverse flow of the fluid out of the chamber through the inlet passage.
