Abstract
A turbo blood pump having a small size, that is, a small amount of blood to be filled and capable of adjusting and maintaining the slight amount of flow, and a turbo blood pump in which hemolysis is not likely to occur even if it is used at a practically high rotational speed necessary to obtain a predetermined discharging ability. The turbo blood pump to be used includes a housing having an inlet port and an outlet port; and an impeller disposed rotatably in the housing; wherein the impeller includes at least a rotation shaft and an annular connection portion to which the plural vanes are attached. The vane is manufactured so that an inlet side part is in the skew position with respect to an outlet side part.
