Abstract: An elastic venous compression orthosis indicated in cases of vein disorders of a lower limb of a patient, the lower limb having an ankle, a calf and a thigh, the orthosis having an ankle part for enclosing the ankle and a calf part for enclosing the calf, the orthosis having a textile pressure profile such that the textile pressure measured at the ankle is less than 10 mmHg, and the textile pressure measured at the calf is less than 35 mmHg and greater than 25 mmHg.

Abstract: A rotor disc includes a rim and a balancing device, which includes housings formed in the rim, and balancing masses housed in at least some of the housings.

Abstract: The surgical stocking made by knitting a knitting yarn together with an extensible weft yarn is a placebo type stocking suitable for exerting compressive pressure at the ankle of less than 8 mmHg, and preferably less than 5 mmHg. It is intended for double blind tests versus placebo using a product having the same structure, the same visual appearance, and the same feel as an active stocking but compression that is negligible and thigh/ankle degressivity that is close to unity. The weft yarn presents mass per unit length lying in the range 250 dtex to 600 dtex, preferably in the range 350 dtex to 500 dtex, with the proportion of elastic material being less than 25% and preferably less than 20% of the total weight of the thread. Its elongation capacity lies in the range 200% to 350%, preferably in the range 200% to 300%, but its springiness (II) is very different from that of an elastic stocking (I).

Abstract: The balancing device is applicable to a rotor (10) disk (14) provided with a rim (18). It comprises housings (36, 38) formed in the rim (18), balancing masses (40, 30) housed in the housings (36, 38), the housings (36, 38) being closed off by a spring retaining ring (44, 442, 444). Application to a rotor (10) with integrally bladed disks (14).
