Аннотация
In this work, the effect of rotor geometry on the H−Q curves of the Sputnik implantable pediatric rotary blood pump was studied. Load sensitivity was calculated for different input angles of the pump impeller and diffuser blades. Hydraulic efficiency and shear stress were determined for each modification of the pump design. The study showed that variation of the input angles of the impeller and diffuser blades had a significant effect on the load sensitivity of the pump. An almost twofold increase in the load sensitivity was achieved (from 0.03420 to 0.05957 L·min−1·mm Hg−1).
