Title
(EN) MULTIPLE ROTOR, WIDE BLADE, AXIAL FLOW PUMP
(FR) POMPE A FLUX AXIAL, A LARGES AILETTES ET A ROTORS MULTIPLES
Abstract
(EN) A blood pump comprises a pump housing; a plurality of rotors positioned in said housing, each rotor comprising an impeller having a hydrodynamic surface for pumping blood; and a motor including a plurality of magnetic poles carried by each impeller, having motor stators, each including electrically conductive coils located adjacent to or within the housing. At least one of the rotors is adopted to rotate clockwise, and at least one of rotors is adopted to rotate counterclockwise. By this means, stator or stationary blades between the rotors may not be needed.
(FR) Cette invention concerne une pompe à sang, qui comprend un logement de pompe; plusieurs rotors placés dans ce logement et comprenant chacun une roue avec une surface hydrodynamique pour le pompage du sang; et un moteur contenant plusieurs pôles magnétiques placés sur chaque roue, avec des stators de moteur, contenant chacun des bobines électroconductrices placées à proximité adjacente ou à l'intérieur du logement. Au moins l'un des rotors est conçu pour tourner dans le sens des aiguilles d'une montre et au moins l'un des rotors est conçu pour tourner dans le sens contraire des aiguilles d'une montre. Grâce à cet agencement, des ailettes fixes ou de stator entre les rotors peuvent ne pas être nécessaires.
