Title (EN) METHODS AND SYSTEMS FOR DETECTING AN OCCLUSION IN A BLOOD CIRCUIT OF A DIALYSIS SYSTEM
(FR) PROCÉDÉS ET SYSTÈMES POUR DÉTECTER UNE OCCLUSION DANS UN CIRCUIT SANGUIN D'UN SYSTÈME DE DIALYSE
Abstract:
(EN) The present specification describes systems and methods for detecting an occlusion in a tubing carrying a patient's blood through a manifold and into a dialyzer in a dialysis system. A controller measures pressures value of the blood at a predetermined point after exiting the manifold and before entering the dialyzer, calculates a historical running average, calculates a weighted sum of the most recent pressure values, and determines whether to trigger an occlusion alarm based on a function of the historical running average and the weighted sum of the most recent pressure values.
(FR) La présente invention concerne des systèmes et des procédés destinés à détecter une occlusion dans une tubulure transportant le sang d'un patient à travers un collecteur et dans un dialyseur dans un système de dialyse. Un dispositif de commande mesure la valeur de pression du sang à un emplacement prédéterminé après la sortie du collecteur et avant l'entrée dans le dialyseur, calcule une moyenne flottante d'historique; il calcule une somme pondérée des valeurs de pression les plus récentes et détermine s'il faut déclencher une alarme d'occlusion sur la base d'une fonction de la moyenne flottante d'historique et de la somme pondérée des valeurs de pression les plus récentes.
