Abstract: A hydraulic optimal designing method of a centrifugal blood pump is provided to be suitable for the blood pump used for both the exterior and interior of the body by reducing the volume by using only one moving part that is an impeller. The method for optimally designing a centrifugal blood pump impeller and a volute casing satisfies the following four conditions. In the distribution of streamwise static pressure, the streamwise static pressure is gradually increased without a sudden change. In the characteristic of load of an impeller vane, blood pressure applied on a pressure surface and a suction surface of the pump impeller is properly distributed to prevent blood clots in the blood pump. In the distribution of velocity vector in leading and trailing edges of the impeller, the direction of a flow entering the leading edge of the impeller is kept at the proper angle for the angle of an inlet vane and the recirculation of the flow is minimized at the trailing edge. In the distribution of velocity vector at a volute casing inlet and a passage, a flow field of the volute casing inlet corresponds to the flow condition of the impeller outlet so that the flow angle of an impeller outlet matches with a tangent line of a volute tongue.
