Abstract
La présente invention concerne un pléthysmographe à jauge de mercure pour l'étude de la variation de volume des vaisseaux sanguins. Le pléthysmographe selon l'invention comporte deux générateurs de courant debitant respectivement dans la jauge et une résistance variable de valeur connue des courants constants d'intensités connues et des moyens de comparaison des tensions aux bornes de la jauge et de la résistance variable. Cet appareil évite l'utilisation d'enregistreur de type particulier et permet de ne procéder qu'à un seul et unique étalonnage.
