Abstract

L'invention concerne un appareil de diagnostic destiné à recueillir des informations sur un être vivant. Des ondes cérébrales sont détectées sous forme de signaux électriques qui sont traités pour en tirer des paramètres. Les variations de ces paramètres en fonction du temps sont visualisées ou enregistrées en vue du diagnostic. L'invention s'applique notamment au contrôle de la dialyse par un rein artificiel.
