CENTRIFUGAL PUMP FOR MECHANICAL BLOOD CIRCULATION SUPPORT Russian patent published in 2019 - IPC A61M1/12 

FIELD: medical equipment.

SUBSTANCE: invention refers to medical equipment, namely to implantable devices for mechanical blood circulation support, can be used for treating the patients with terminal stage of cardiac failure. Centrifugal pump rotor pump for blood pumping with outer diameter of 20–70 mm has 2–8 tubular channels of constant cross-section with diameter of 1–6 mm. Channels are swirled on a logarithm curve by 0.4–10 turns so that the output angle of each channel from the rotor, formed by a tangent to the corresponding logarithmic curve and tangent to rotor disc outer circumference in intersection point of said curves is 1–15 degrees.

EFFECT: technical result is reduced hematolysis and thrombosis.
