Title
(EN) SYSTEM FOR CARDIAC ASSISTANCE, METHOD FOR OPERATING THE SYSTEM AND CARDIAC SUPPORT METHOD
(FR) SYSTÈME D'ASSISTANCE CARDIAQUE, PROCÉDÉ DE FONCTIONNEMENT DU SYSTÈME ET PROCÉDÉ DE SUPPORT CARDIAQUE
Abstract
(EN)
The present invention relates to an extracorporeal cardiac assistance system (10), comprising a pump (18) being configured to create a fluid flow from a suction line (12) to a pressure line (14) of the system; further comprising a control device (22) configured to control the pump (18) and/or an adjustable flow limiter (20) to provide an adjustable flow rate and/or a pressure, wherein the control device (22) is configured to execute a support mode with a plurality of consecutive support flow rate pulses and/or support pressure pulses interposed on the fluid flow and to execute a weaning mode with a plurality of such pulses, wherein an amount of energy provided to the fluid flow with each pulse is lower in the weaning mode than in the support mode. The invention further relates to a method for operating the system (10) and to a treatment method.
(FR)
La présente invention concerne un système d'assistance cardiaque extracorporel (10), comprenant une pompe (18) configurée pour créer un écoulement de fluide à partir d'une ligne d'aspiration (12) jusqu'à une ligne de pression (14) du système ; comprenant en outre un dispositif de commande (22) configuré pour commander la pompe (18) et/ou un limiteur de débit réglable (20) servant à fournir un débit réglable et/ou une pression, le dispositif de commande (22) étant configuré pour exécuter un mode de support avec une pluralité d'impulsions de débit de support consécutives et/ou d'impulsions de pression de support interposées sur l'écoulement de fluide et pour exécuter un mode de sevrage avec une pluralité de ces impulsions, la quantité d'énergie fournie à l'écoulement de fluide avec chaque impulsion étant inférieure dans le mode de sevrage que dans le mode de support. La présente invention concerne en outre un procédé de fonctionnement du système (10) et une méthode de traitement.
