According to the impeller suitable for right ventricle auxiliary blood pumping and good in water conservancy performance and hemolytic performance and the right ventricle auxiliary device thereof, blood is pumped from the inferior vena cava, bypasses the right atrium and the right ventricle and is pumped into the pulmonary artery, and therefore the impeller pumps blood from the near end of the impeller to the far end of the impeller; in the process that blood is conveyed to the far end from the near end of the impeller, due to the fact that the diameter of the hub is gradually increased, the flowing speed of the blood can be increased, but based on the fact that the far end of the hub is of the spherical dome structure, the flowing loss of the blood can be reduced, blood damage is reduced, flowing dead zones are avoided, and the flowing-out direction of the blood can be effectively adjusted. Blood flows out in the axial direction, the flowing mixing loss is reduced, the blood pumping efficiency is further imp
