Abstract: Method for selecting an elastic venous restraint orthosis intended to be slipped onto a lower limb of a patient. Acquisition of a photograph representing the skin of the limb and a calibration map including one or more calibration zones. The calibration map is placed on the limb in a position termed the “acquisition position.” Calibration of the photograph by the calibration zone or zones, in such a way that the representation of the skin on the photograph exhibits a calibrated colour. Selection, as a function of the calibrated colour, by computer and from a set of colours of a tone chart, of a tone chart colour, preferably of the tone chart colour closest to the calibrated colour, termed the “optimal colour,” and then determination, by computer, of an orthosis colour as a function of the tone chart colour selected. Selection of an orthosis exhibiting the orthosis colour.

Abstract: A device determines and displays compression values to be exerted by an orthosis upon the surface of a member and produces digital simulation (10) for simulating the action of the compression on the hemodynamics of venous return furnishing values of blood flow and/or of intravenous pressure at a number of points of a digital model representing the venous network of the leg of the member, which display is a value oriented graph containing a number of interconnected arcs, with each arc assigned a corresponding value of blood flow and/or intravenous pressure, and which compression values are furnished by simulation software based on morphological characteristics of the member and on dimensional and rheological characteristics of the orthosis.

Abstract: The inventive device comprises: means for producing compression values (14; 16) for being exerted by the orthosis upon the surface of the member; digital simulation means (10) for simulating the action of the compression on the hemodynamics of the venous return furnishing values of blood flow and/or of intravenous pressure at a number of points of a digital model representing the venous network of the leg of the member, and: means (26) for presenting these values. These are displayed in the form of a valued oriented graph containing a number of interconnected arcs with, assigned to each arc, a corresponding value of blood flow and/or of intravenous pressure. The compression values can be furnished by a simulation software based on morphological characteristics of the member (20) and on dimensional and theological characteristics of the orthosis (22).

Abstract: The orthosis comprises a leg portion and a foot portion. The leg portion which extends upwards from the ankle serves to apply therapeutic compression to the leg once the orthosis has been put on. The foot portion which extends from the malleolar region to the toes and covers the instep is a shaped portion that envelops the foot elastically. The dimensioning and the mesh structure of the foot portion are such that 0<Px<Pm<Pb once the orthosis has been put on, Px being the pressure applied to the instep region, Pm being the pressure applied to the malleolar region, and Pb being the therapeutic compression applied to the ankle region. Preferably, Px=5 mmHg±25% and Pm=0.5(Pb+Px)±25%.
