Title (EN) BIOMEDICAL APPARATUS WITH A PRESSURE-REGULATED BLOOD PUMP
(FR) APPAREIL BIOMÉDICAL ÉQUIPÉ D'UNE POMPE SANGUINE RÉGULÉE PAR LA PRESSION
Abstract:
(EN) A biomedical apparatus for pumping blood of a human or an animal patient through a secondary blood circuit (10, 11, 12) is provided, comprising a blood pump (10), an inlet duct (11) and an outlet duct (12) for guiding blood of the patient to the blood pump (10) and back to the patient. The apparatus further comprises a measuring device (14) with at least one pressure sensor (40-46) for measuring pressure values in the patient's circulatory system. A controller (13) is provided that comprises at least two different preset control algorithms for regulating the operating point of the blood pump (10) based on the measured pressure values. The controller (13) is configured to select one of these preset control algorithms for being applied in dependence on the position of the at least one pressure sensor (40-46) in the patient's circulatory system.
(FR) L'invention concerne un appareil biomédical destiné à pomper le sang d'un patient humain ou animal à travers un circuit sanguin secondaire (10, 11, 12), et comprenant une pompe sanguine (10), un conduit d'entrée (11) et un conduit de sortie (12) pour guider le sang du patient vers la pompe sanguine (10), puis le renvoyer au patient. L'appareil comprend en outre un dispositif de mesure (14) comportant au moins un capteur de pression (40-46) pour mesurer des valeurs de pression dans le système circulatoire du patient. Un dispositif de commande (13) comprend au moins deux algorithmes différents de commande prédéfinis pour réguler le moment de fonctionnement de la pompe sanguine (10) sur la base des valeurs de pression mesurées. Le dispositif de commande (13) est conçu pour sélectionner l'un de ces algorithmes de commande prédéfinis afin qu'il soit appliqué en fonction de la position du ou des capteurs de pression (40-46) dans le système circulatoire du patient.
