Title (EN) APPARATUS FOR CONTROLLING HEART ASSIST DEVICES
(FR) APPAREIL DE COMMANDE DE DISPOSITIFS D'ASSISTANCE CARDIAQUE
Abstract: front page image
(EN)An apparatus for a heart assist device, comprising a processing unit for computing the blood flow rate from the arterial pressure curve and for predicting at every heartbeat the closing time of the heart valve from the curve of the blood flow rate. The processing unit is adapted to deliver a signal for controlling a heart assist device at a point in time, a period ahead in time of the closing time of the heart valve, wherein the mechanical properties of said heart assist device are taken into account in determining said period. The apparatus adapts itself to changes in a patient's heart frequency and aortic pressure.
(FR)L'invention porte sur un appareil pour dispositif d'assistance cardiaque comprenant une unité de traitement calculant le débit sanguin à partir de la courbe de pression artérielle et prédisant à chaque battement le temps de fermeture de la valvule cardiaque à partir de la courbe de débit sanguin. L'unité de traitement est conçue pour émettre un signal à l'instant précédant la fermeture de la valvule cardiaque, le décalage étant fonction des caractéristiques du dispositif d'assistance. L'appareil s'adapte de lui-même aux variations de la fréquence cardiaque et de la pression aortique du patient
