HELICAL FLOW PUMP FOR BLOOD

摘要

[PROBLEMS] To realize a rotary pump capable of opening an inflow port in the peripheral surface side and preventing eccentric torque from acting on its rotating shaft. [MEANS FOR SOLVING THE PROBLEMS] This helical flow pump comprises a disk-like rotary body (3) having liquid-passing holes around its outer peripheral portion and a helical inflow passage (2) opened in one side surface of the rotating body (3) toward the outer peripheral portion and reduced in its cross section in the rotating direction of the rotary body.
