  • Design ideas and techniques applied in aeronautical turbomachinery were used to develop the impeller blood pump LAP-Ⅰ,which was designed for clinical use for Asian patients.By combining aeronautical turbomachinery technique with medical need,an integrated rotor and a cantilever stator were applied in the structure design,a further improvement was made in the tandem cascades stator and the impeller blood pump LAP-Ⅱ was obtained.The simulation results of computational fluid dynamics show that,the pressure rise characteristic of blood pump LAP-Ⅱ meets the medical requirement,and the flow status in the pump is fluent.The maximal comparative shear stress (S) value is reduced evidently;and the streamlines show that the longest time required for blood to travel through the pump is decreased,thus the property of anti-hemolytic application is improved.
