Patent ID: 8221338

Claim:
A therapeutic treatment appliance for treating living tissue (T), the appliance comprising a casing ( 1 ), an ultrasound therapeutic transducer ( 2 ) mounted in the casing, and a diaphragm ( 3 ) mounted on the casing ( 1 ), the diaphragm ( 3 ) being designed to come into contact with an application surface (S) of the tissue (T); the diaphragm ( 3 ), the transducer ( 2 ), and the casing ( 1 ) together defining a chamber ( 4 ) that is filled with an acoustic coupling liquid (L) that flows through the chamber between an inlet ( 41 ) and an outlet ( 42 ); the transducer ( 2 ) being placed in such a manner as to emit ultrasound through a propagation zone (Z) of the chamber towards the diaphragm ( 3 ); a first temperature sensor ( 51 ) placed close to the inlet ( 41 ) and a second temperature sensor ( 52 ) placed close to the outlet ( 42 ), the sensors ( 51 , 52 ) delivering signals that are representative of temperatures, wherein the temperature sensors are situated outside the propagation zone; and electronics (E) receiving the temperature signals delivered by the temperature sensors ( 51 , 52 ) to establish a temperature difference (ΔT).
