FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, in particular to a centrifugal pump of extracorporeal membrane oxygenation (ECMO) systems. Pump includes a seal in the side cavity between the pump housing and the closed impeller, wherein said seal is composed of radial or shaped impeller vanes arranged on impeller cover plate outer wall.
EFFECT: use of blades in the gap between the outer wall of the impeller cover plate and the pump housing will make it possible to reduce blood trauma during its pumping through the pump and to ensure high energy efficiency of the pump.
