Abstract

The instrument is comprised of processing means in order to qualify the force exerted on biological surfaces and the collapse caused by said force, said means being characterized in that they are portable and comprise a case with indentation means (1) including a housing for a strip (6) carrying the displacement transducer (12), as well as means for supporting (13, 15 and 34) the indentation means (1), between which is interleaved the force transducer (20) so that when applying a force to the biological surface, after having done the indentation, the strip (6) is displaced and the mechanical preservation condition of said surface is known through the processing means.
