Abstract
The device for studying vascular behavior particularly in a lower limb of a patient comprises pressure applying means for causing occlusion of the limb under study, means for controlling the characteristics of progressive variation in the pressure applied by the pressure-applying means as a function of time during occlusion of the limb under study, a plethysmograph for delivering signals which are representative of an electrical impedance related to the limb under study and of variations in such electrical impedance, and means for determining, from coefficients of standardization which are characteristic of the healthy vascular operation of a normal limb of the same type as the limb under study and from the signals, indices which are representative of the vascular behavior of the limb under study.
