Abstract:
The invention relates to a device for assistance in the selection of a compression orthesis and in adapting same to the morphology of a limb. The inventive device consists of: means (26) for establishing a first file containing data representative of the morphological characteristics of the limb (30), comprising the three-dimensional co-ordinates of a mesh of points (68) with different heights; means (10) for establishing a second file containing data representative of the dimensional and rheological characteristics of the orthesis, which are defined with different heights; compression simulation means (48) which, using the data from the first and second files, can determine the compression pressure values that are likely to be exerted by the orthesis on the limb at a plurality of points of said mesh; and means (50) for displaying the pressure values thus determined in a graphical manner, for example, by overlaying a 3D graphical representation of the limb, or a section of same, with the false color- or grey level-coded calculated pressure.
Abstract:
The device comprises means for taking a height measurement (H) and a plurality of circumference measurements (b, c, g) on the limb of the patient at different predetermined z-positions (zb, zc, zg). A first data file includes the coordinates (X0, Y0, Z0) of a first mesh of points (24) representative of the morphological characteristics of a reference limb, these points being distributed over the surface of the reference limb along a succession of outlines (26) defined at different successive Z-positions. Morphology generator means recalculate the coordinates of the first mesh of points as a function of the height measurement (H) and of the circumference measurements (b, c, g) in such a manner as to produce a second data file comprising the coordinates (x, y, z) of a second mesh of points (52) representative of morphological characteristics of the patient's limb.
Abstract:
A method for determining a size grid, the method comprising following steps: a) determination of N morphological parameters, N being ≥2; b) acquisition of a set of values of the parameters for a sample of a targeted population of individuals, each individual being associated with an individual point supplying, for each parameter, a value of the parameter; c) independently of steps a) and b), determination of rate of coverage of sample to be covered by the grid; d) determination of a set of coverage zones, each coverage zone being a set of individual points relating to a set of individuals for which a same orthesis according to the model is adapted and thus corresponding to a size adapted to set of individuals; the number of coverage zones being determined such that percentage of individual points included in at least one coverage zone is ≥ the desired coverage rate.

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:
A tubular sleeve (40) comprises an anterior portion (16) of inextensible material that comes to bear against the tibial ridge, and a posterior portion (18) of extensible material covering the region to be compressed. These two portions are connected together along two connection generator lines (20). Inflatable balloons (22) are disposed on the inside face of the anterior portion, being interposed between the inextensible material and the tibial crest. Means (24, 26, 28) are provided for inflating each of the balloons differently to a respective given pressure so as to apply deformation to the anterior portion of the sleeve that is suitable for inducing a traction force that is exerted on the extensible posterior portion; this force is distributed regularly along the generator lines and acts perpendicularly thereto, and consequently leads to compression action on the compressible region of the limb.
