Abstract[English]
A hemodialysis system is provided including a dialyzer, a closed loop blood flow path, a dialysate flow path, and blood and dialysate pumps. A processor controls the flow of blood through the blood flow path, and the processor controls the flow of dialysate through the dialysate flow path. The hemodialysis system includes various sensors which are connected to the processor for providing data concerning various treatment parameters. The processor monitors the various parameters of the hemodialysis machine and applies one or more prestored algorithms, algorithms created by artificial intelligence (Al) or other forms of machine learning performed by the machine or calculated remotely, to more accurately predict and control the dialysate flow rate and/or blood flow rate. Preferred parameters being monitored by the processor to improve flow rate determination and control include pump head speed, inlet and outlet pressure, tubing age (measured by pump rotations), and fluid temperature.[French]
L'invention propose un système d'hémodialyse comprenant un dialyseur, un trajet de flux sanguin en boucle fermée, un trajet d'écoulement de dialysat et des pompes de sang et de dialysat. Un processeur règle la circulation de sang dans le trajet de flux sanguin et le processeur règle la circulation de dialysat dans le trajet d'écoulement de dialysat. Le système d'hémodialyse comprend divers capteurs qui sont connectés au processeur pour fournir des données concernant divers paramètres de traitement. Le processeur surveille les divers paramètres de la machine d'hémodialyse et applique un ou plusieurs algorithmes préstockés, algorithmes créés par intelligence artificielle (Al) ou d'autres formes d'apprentissage automatique effectuées par la machine ou calculées à distance, pour prédire et réguler plus précisément le débit de dialysat et/ou le flux sanguin. Des paramètres préférés qui sont surveillés par le processeur pour améliorer la détermination et la commande du débit comprennent la vitesse de la tête de pompe, la pression d'entrée et de sortie, l'âge du tube (mesuré par les rotations de la pompe) et la température du fluide.
