Abstract

Cette invention se rapporte au domaine de la fabrication d'instruments médicaux et peut être utilisée afin d'effectuer des diagnostics rapides de l'état fonctionnel de l'organisme d'une personne. Ce dispositif comprend un convertisseur qui va transformer la conductivité mesurée et la conductivité d'étalonnage en une suite d'impulsions dont la durée relative est proportionnelle à la conductivité mesurée. Le circuit comprend un système de protection contre les impulsions de tension dans les électrodes de mesure. Ce dispositif comprend également une unité optoélectronique, ainsi qu'une source d'alimentation se présentant sous forme d'un inverseur de la tension du port série d'un ordinateur. Des enroulements primaires et secondaires sont disposés sur des conducteurs magnétiques distincts qui sont connectés l'un à l'autre par une spire en court-circuit. Cet appareil répond aux exigences en matière de sécurité électrique, et permet d'abaisser le niveau des interférences réciproques entre le dispositif et l'ordinateur.
