Title (EN) BLOOD LEAK MONITORING METHOD AND APPARATUS
(FR) PROCEDE ET APPAREIL DE MONITORAGE DE PERTES SANGUINES
Abstract:
(EN) A method for monitoring for leaks or disconnections in an extracorporeal blood circuit, comprising the steps of operating a blood pump to circulate blood through an extracorporeal blood circuit; opening a shunt connection between the arterial and venous blood flow portions; sensing the presence of air from any leaks or disconnections within the venous blood flow portion, and taking corrective action if the presence of air is noted. The shunt connection is typically periodically but only briefly opened, to check for leaks in the typically positive pressure portion of the venous set.
(FR) Ce procédé de monitorage de pertes ou déconnexions dans un circuit sanguin extracorporel consiste à utiliser une pompe sanguine pour faire circuler le sang à travers un circuit extracorporel; ouvrir une connexion en parallèle entre les parties d'écoulement sanguin artérielle et veineuse; détecter la présence d'air dans les fuites ou déconnexions au sein de la partie d'écoulement sanguin veineuse et prendre les mesures adéquates en cas de présence d'air. la connexion en parallèle est normalement périodique, mais ne s'ouvre que brièvement afin de vérifier les fuites dans la partie de pression normalement positif des veines.
