The subject matter of the present invention is a system for measuring interface pressure exerted on the skin, that is in particular of use in compression therapy, characterized in that it comprises: - a supporting means bearing sensors, including at least two pressure sensors spaced out on the supporting means in order to make it possible to measure the pressure exerted at two predetermined positions; - an electronic system connected to the sensors and capable of acquiring the values simultaneously measured by these sensors; and in that each pressure sensor comprises a transducer element, which is preferably substantially flat, said transducer element having a surface intended to come into contact with the skin in the operating position, either directly or by means of a layer of a material covering said surface of the transducer, the elastic modulus of compression of said transducer or of said intermediate layer, measured at the surface intended to come into contact with the skin, being between 30 and 500 kPa, preferably between 80 and 400 kPa and more preferably between 200 and 400 kPa. Use: compression therapy.

La présente invention a pour objet un système de mesure de pression d'interface exercée sur la peau, notamment utile en thérapie compressive, caractérisé en ce qu'il comprend : - un support portant des capteurs dont au moins deux capteurs de pression disposés de façon espacée sur le support pour permettre de mesurer la pression s'exerçant en deux emplacements prédéterminés; - un système électronique relié aux capteurs et apte à acquérir les valeurs mesurées simultanément par ces capteurs; et en ce que chaque capteur de pression comprend un élément transducteur, de préférence sensiblement plat, ledit élément transducteur présentant une surface destinée à venir au contact de la peau en position d'utilisation, soit directement soit par l'intermédiaire d'une couche d'un matériau recouvrant ladite surface du transducteur, le module élastique de compression dudit transducteur ou de ladite couche intermédiaire, mesuré au niveau de la surface destinée à venir au contact de la peau étant compris entre 30 et 500 kPa, de préférence entre 80 et 400 kPa et de préférence encore entre 200 et 400 kPa. Application: thérapie compressive.
