[0043] The technical scheme of the present invention will be further described below in conjunction with the drawings and embodiments.
[0044] A tandem cascade stator structure of an artificial heart blood pump is characterized in that: the tandem cascade stator structure includes a stator hub channel and its stator blades
[0045] 1. The stator hub runner adopts a streamlined cubic spline curve runner, such as Figure 4a The reference number 8 shows. This streamlined flow channel prevents the sudden expansion of pressure and is beneficial to inhibit the separation of flow in the stator blade area. The axial range of the cubic spline streamlined stator hub is as follows Figure 4a As indicated by number 13, the meridian coordinates of the interpolation point of the cubic spline curve are as follows, the abscissa is the axial coordinate of the interpolation node, and the ordinate is the span direction coordinate of the interpolation node on the vertical axis, and the unit is m:
