摘要： A centrifugal impeller for a blood pump, and a blood pump are provided. The centrifugal impeller comprises a circular base plate, centrifugal blades, and a supporting structure. A through hole is formed in the middle of the base plate to form a secondary flow path. The centrifugal blades are arranged on the upper surface of the base plate, each centrifugal blade is a banana-shaped blade which is thick in middle and thin at both ends, and a wrap angle of each centrifugal blade is greater than or equal to 90°, and the centrifugal blades extend radially from the outer edge of the through hole to the periphery of the base plate. The supporting structure comprises a supporting shaft arranged at the center of the through hole and supporting blades, one end of each supporting blade is connected to the supporting shaft, and another end is connected to the base plate.
