<p>The present invention provides a pump by vessel revolution comprising a vessel (1) having an inlet (2) for liquid and an outlet opening (3) in a specific tangential direction of an outer peripheral portion thereof, wherein the vessel (1) is revolved in a specific direction thereby outflowing the liquid through the outlet opening (3). Accordingly, the interior of the vessel (1) conducts a simple centrifugal motion and therefore when the pump is used particularly for the blood circulation device such as artificial heart or assisted circulation, and the blood is completely shut off from outside to free from entry of various germs, air, foreign matter, etc. The pump is simple in construction and excellent in reliability and durability.</p> |
