Abstract

Cette invention concerne une turbo-pompe axiale de type sans contact servant à propulser les sang. La pompe à sang est composée d'un corps de pompe (24) qui délimite un axe de la pompe et présente un orifice d'admission et un orifice de sortie à des extrémités axiales opposées du corps de pompe, d'une unité rotor (17) qui délimite un axe rotor et des extrémités axiales opposées du rotor. La pompe suspend magnétiquement le rotor à l'intérieur du corps de pompe, aux extrémités axiales du rotor, de manière à éviter un contact physique dans le corps de pompe et à délimiter des espaces fluidiques entre les extrémités axiales du rotor et les éléments de suspension magnétique (13)(13').
