CA 2489521

The invention concerns a device wherein a tubular sleeve (14) comprises a front part (16) made of inextensible material urged to be pressed against the tibial ridge, and a rear part (18) made of extensible material enclosing the region to be compressed. Said two parts are linked along two linking generators (20). Inflatable balloons (22) are arranged on the inner surface of the front part, interposed between the inextensible material and the tibial ridge. Means (24, 26, 28) are provided for differential inflating of each of the balloons to a given pressure, so as to apply to the sleeve front part a deformation designed to induce a tensile force exerted on the extensible rear part; said force is uniformly distributed along the generators perpendicularly thereto and hence brings about a compressive action on the compressible region of the limb.

Un manchon tubulaire (14) comporte une partie antérieure (16) en materiau inextensible venant en appui contre la crête tibiale, et une partie postérieure (18) en matériau extensible enveloppant la région a comprimer. Ces deux parties sont reliées le long de deux génératrices de liaison (20). Des ballonnets gonflables (22) sont disposés sur la face intérieure de la partie antérieure, en interposition entre le matériau inextensible et la crête tibiale. II est prévu des moyens (24, 26, 28) pour gonfler de manière différenciée chacun des ballonnets à une pression donnée, de manière à appliquer à la partie antérieure du manchon une déformation propre à induire un effort de traction exercé sur la partie postérieure extensible; cet effort est reparti régulièrement le long des génératrices perpendiculairement à ces dernières et entraîne lui-meme, par voie de consequence, une action de compression sur la region compressible du membre.
