一种用于血泵的泵转子及辅助血液循环装置
By setting swept-back and backward-curved structures at the leading and trailing edges of the blood pump rotor blades, the load distribution of the blades and the direction of blood flow are adjusted, solving the problem of difficulty in increasing the flow rate and head of existing blood pumps, and achieving a significant improvement in blood pump efficiency and flow rate.

AI Technical Summary
Existing impeller designs are limited by factors such as blood vessel size, intervention methods, and hemolysis, making it difficult to increase blood pump flow and head. Furthermore, the existing axial flow pump blade configuration design is simple and has failed to significantly improve pumping efficiency.
A swept-back structure is set on the leading and trailing edges of the blades of the blood pump rotor, combined with a backward-curving structure, to adjust the load distribution of the blades and the direction of blood flow, so as to improve the working capacity of the blades and reduce flow loss.
While maintaining the same shape and speed of the blood pump, the pump's pressurization capacity and pumping volume were improved, end-wall loss was reduced, and the clinical hemolysis performance requirements were met.
