Title (EN) BLOOD PROCESSING APPARATUS WITH AIR BUBBLE DETECTOR
(FR) APPAREIL DE TRAITEMENT DU SANG AVEC DÉTECTEUR DE BULLES D'AIR
Abstract:
(EN) A centrifuge (16) for separating blood and blood components having a blood processing vessel (12) mounted on a rotor of a centrifuge. A sensor (172) in the outflow race (170) of a return peristaltic pump (142) detects air bubbles in the fluid within a return loop. The sensor may be a sonic sensor, a sonic pulse echo sensor, or capacitive plates. A pre-determined minimum bubble size or sizes or a cumulative volume may be selected, and the device operator may be warned only of the existence of bubbles that exceed a certain size or of a cumulative volume of bubbles, or the blood donation procedure may be stopped if a bubble exceeds a certain critical size or if a pre-determined volume of bubbles over a certain period or volume of fluid is exceeded.
(FR) L'invention concerne une centrifugeuse (16) pour séparer le sang et les composants du sang, qui comprend un récipient de traitement du sang (12) monté sur un rotor d'une centrifugeuse. Un capteur (172) dans le trajet d'écoulement (170) d'une pompe péristaltique de retour (142) détecte les bulles d'air dans le fluide à l'intérieur d'une boucle de retour. Le capteur peut être constitué d'un capteur sonique, d'un capteur d'impulsions-échos soniques ou de plaques capacitives. Une ou plusieurs tailles minimales de bulle ou un volume cumulé prédéterminés peuvent être sélectionnés, et l'opérateur du dispositif peut n'être alerté que de la présence de bulles qui dépassent une certaine taille ou d'un volume cumulé de bulles, ou le processus de don du sang peut être arrêté si une bulle dépasse une certaine taille critique ou si un volume prédéterminé de bulles est dépassé pendant une certaine période ou pour un certain volume de fluide.
