Abstract

Une pompe centrifuge à sang se caractérise par un ensemble pompe (14) comportant un corps cylindrique pouvant s'insérer dans un stator (12) de moteur. Le corps cylindrique renferme un rotor (58) de moteur qui est couplé directement à la roue hélice (40) de la pompe. Le corps cylindrique peut être orienté et bloqué dans le stator du moteur selon différentes orientations angulaires. On prévient l'hémolyse en dépit d'un fonctionnement à grande vitesse, en réduisant le jeu entre la roue hélice (40) et la chambre de cette dernière, et en arrondissant les arêtes des pales de la roue hélice, et en plaçant un détecteur pour empêcher le sang d'être propulsé plus d'une fois autour de la chambre de ladite roue hélice. Un mécanisme de verrouillage libérable efficace est également décrit, ainsi qu'un procédé préféré d'assemblage de l'ensemble pompe avec des tolérances étroites.
