<p>A pump for moving a fluid, as blood, having a body and end members forming a cylindrical chamber. A free floating piston located in the chamber is moved along the length of the chamber with a solenoid to pump blood into and out of opposite ends of the chamber. The end members containing inlet and outlet valves and sleeves are adapted to attach to veins or tubes to carry the blood to and from the pump. When electrical power is applied to the solenoid, a magnetic force operates o move the piston in the chamber, thereby pumping blood into and out of the chamber through the valves in the opposite end members.</p> |
