The invention relates to a centrifugal separator for a physiological fluid, particularly blood. The inventive separator comprises: a fixed conduit (3) which continuously supplies a rigid disposable centrifugation chamber (1) with the liquid to be separated; a fixed outlet conduit (9) having an inlet port which is located in a concentrated area of at least one of the separated constituents having the lowest mass density in order for same to be removed continuously, said conduits (3, 9) being solidly connected to a fixed part (4) of the chamber (1); means (21) for guiding the chamber (1) in rotation and means (20) for driving the chamber around the axis of rotation defined by said guide means (21). The invention also comprises a second fixed outlet conduit (8) having an inlet port which is located in a concentrated area of at least one of the separated constituents having the highest mass density in order for same to be removed continuously.
Ce séparateur centrifuge pour un fluide physiologique, en particulier pour le sang, comprend un conduit fixe (3) pour alimenter en continu une enceinte jetable (1) rigide de centrifugation en liquide à séparer, un conduit fixe (9) de sortie dont l'ouverture d'admission se situe dans une zone de concentration d'au moins un des constituants séparés présentant la masse spécifique la plus faible pour le retirer en continu, ces conduits (3, 9) étant solidaires d'une partie fixe (4) de ladite enceinte (1), des moyens de guidage en rotation (21) de cette enceinte (1) et des moyens d'entraînement (20) de ladite enceinte autour de l'axe de rotation défini par ces moyens de guidage (21). Il comporte un second conduit fixe (8) de sortie dont l'ouverture d'admission se situe dans une zone de concentration d'au moins un des constituants séparés présentant la masse spécifique la plus élevée pour le retirer en continu.
