CA 2517734

Apparatus (10) for processing blood in an extracorporeal circuit (110) with automatic flow control is provided in which error conditions are sensed and system operation is modulated responsive to the error conditions. The apparatus includes an extracorporeal blood processing system (31), at least one sensor (25-27) to sense the presence of gas or to monitor venous pressure, and a controller (33) operably coupled to the blood processing system to selectively reduce pump speed or reconfigure flow paths the blood processing system responsive to the sensor output.

La présente invention a trait à un appareil pour le traitement du sang dans un circuit extracorporel avec contrôle automatique de débit dans lequel les conditions d'erreur sont détectées et le fonctionnement du système est modulé en réaction aux conditions d'erreur. L'appareil comporte un système de traitement de sang extracorporel, au moins un capteur pour détecter la présence de gaz ou pour surveiller la pression veineuse, et un contrôleur relié en fonctionnement au système de traitement de sang pour la réduction sélective de la vitesse de pompe ou la reconfiguration des chemins d'écoulement du système de traitement de sang.
