摘要

Auxiliary device for the selection of a retention orthosis by simulating the effects on venous return hemodynamics. This device comprises means for producing containment pressure values (14; 16) capable of being exerted by the orthosis on the surface of the limb, means (10) for numerically simulating the containment action on venous return hemodynamics that release blood flow values. and / or intravenous pressure at a plurality of points of a numerical model representative of the venous network of the limb leg, and means (26) for presenting these values. These are displayed in the form of an appraised oriented graph, comprising a plurality of interconnected arcs, with, associated with each arc, a corresponding blood flow and / or intravenous pressure value. The retention pressure values can be released by a simulation soft from the morphological characteristics of the limb (20) and the dimensional and rheological characteristics of the orthosis (22).
