Title
(EN) BLOOD PUMP WITH PROFILED OUTFLOW REGION
(FR) POMPE A SANG COMPORTANT UNE ZONE D'ECOULEMENT PROFILEE
Abstract
(EN)
The invention provides an axial flow blood pump (10) with slanting outflow components. Specifically, the invention provides a blood pump (10) having an angling outer stator blade edge structure (76, 78, 82, 92) in combination with a blood flow conduit (21, 22) having a constricting inner diameter. After constricting, the blood flow conduit (21, 22) can expand such that the inner diameter of the conduit increases. In addition, the blood pump (10) can have an angling inner stator blade edge structure and a tapering stator blade hub or tapering rotor element (30).
(FR)
L'invention concerne une pompe à sang d'écoulement axial comportant des éléments d'écoulement obliques. Spécifiquement, l'invention concerne une pompe à sang comportant une structure de bord de pale de stator en biais, combinée à un conduit d'écoulement de sang à diamètre interne resserré. Après resserrement, le conduit d'écoulement de sang peut s'élargir de façon à accroître le diamètre interne du conduit. De plus, la pompe à sang peut comporter une structure de bord de pale de stator en biais et un axe de pale de stator conique ou un élément de rotor conique.
