Abstract：To design the blade of axial flow blood pump,and model in three-dimensional drawing software preparing for computa-tional fluid dynamics(CFD)and processing blood pump entity.By application of stream-line method which mainly includes linear a-mendment of circulation distribution and the regular of thicken airfoil,choosing import and export attacking angle reasonably,affording the flow and head of blood pump,we obtained the data for drawing the airfoil cascade,established the model by graphic software UG NX.After processing the data of points about face and back of airfoil cascade,we finished the modeling in UG NX.Compared with the lifting method,with the blade of blood pump by stream-line method,the amending errors by experience and the twist of the blade are reduced.
