Interface pressure measurement system
First Claim
1. A system for measuring an interface pressure exerted on skin, comprising:
- a supporting member;
at least two pressure sensors placed apart on the supporting member, the at least two pressure sensors configured to measure a pressure being exerted at two locations in a use position, wherein at least one of the two locations is predetermined; and
an electronic system connected to the at least two pressure sensors and configured to acquire values simultaneously measured by the at least two pressure sensors,wherein each of the at least two pressure sensors includes;
a transducer element, said transducer element having a surface configured to contact with the skin in the use position, either directly or via an intermediate layer of a material covering said surface of the transducer element, anda compressive elastic modulus of the surface of said transducer element is between 30 and 500 kPa when the surface of the transducer element is configured to contact with the skin directly.

Abstract
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 member bearing sensors, including at least two pressure sensors spaced out on the supporting member 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.
