摘要：
This centrifugal blood pump apparatus includes an impeller provided in a blood chamber, a permanent magnet provided in one surface of the impeller, and a permanent magnet provided in an inner wall of the blood chamber, for attracting the permanent magnet. A centerline of the permanent magnet is arranged at a position different from that of a centerline of a sidewall of the blood chamber such that a rotation centerline of the impeller matches the centerline of the sidewall of the blood chamber during pump operation. Therefore, high torque transmission efficiency is obtained.
