Title
(EN) CENTRIFUGAL BLOOD PUMP
(FR) POMPE A SANG CENTRIFUGE
Abstract
(EN)
A centrifugal pump (10) for pumping biological fluids such as blood includes a housing (12) which defines a pumping chamber (36). The pumping chamber (36) encloses an impeller (14) mounted on a spindle (16). The impeller (14) carries coupling mechanisms which couple with an external source of rotation to rotate the impeller (14). The spindle (16) allows the impeller (14) to rotate freely, but both ends of the spindle (16) are constrained in the axial and lateral directions. The housing (12) includes an inlet (24) and an outlet (26).
(FR)
L'invention concerne une pompe centrifuge (10) conçue pour pomper des liquides biologiques tels que du sang, qui se compose d'un boîtier (12) définissant une chambre de pompage (36). Ladite chambre de pompagne (36) renferme un rotor (14) monté sur un axe (16). Ledit retor (14) supporte des mécanismes de couplage qui s'accouplent avec une source de rotation externe afin de faire tourner le rotor (14). L'axe (16) permet au rotor (14) de tourner librement, les deux extrémités dudit axe (16) étant bloquées dans le sens axial et latéral. Le boîtier (12) comprend une admission (24) et une sortie (26).
