摘要：
The invention relates to a device for pumping blood and can be used as an intra auxiliary device when there is insufficient functioning of the heart, as well as the main pump for auxiliary intracorporeal circulation. The object of the utility model is to increase the efficiency of the device for pumping blood by changing the shape of the flow straightener vane pump apparatus. Under efficiency device for pumping blood understood minimizing hemolysis and thrombosis of blood at given parameters of performance. To solve this problem in a device for blood pumping, comprises placing inside the stator drive the rotor with an axial impeller equipped with permanent magnets, and the straightener, the blades of which have a root and a free peripheral portion, according to the utility model scan root and free peripheral parts of the vanes of the flow straightener machine made in the form of conjugated segments of logarithmic spirals. The technical result of the claimed utility model is to minimize hemolysis and blood thrombosis with given parameters consumption performance and pressure drop with minimal energy consumption in medical devices, pumping blood, by providing a minimum perturbation in the boundary layers blades spremlyayuschego apparatus as well as minimal vortex formation flow and shear stresses . The most effective use of this utility model in medical devices pumping blood, as well as in the pumps, which require minimal degradation of the pumped product.Полезная модель относится к устройствам для перекачивания крови и может быть использовано в качестве внутрикорпоративного вспомогательного устройства при недостаточной работе сердца, а также в качестве основного насоса в системах вспомогательного интракорпорального кровообращения. Задачей полезной модели является повышение эффективности устройства для перекачивания крови путем изменения формы лопаток спрямляющего аппарата насоса. Под эффективностью устройства для перекачивания крови понимается минимизация гемолиза и
