Problems solved by technology

On the other hand, like the other orthoses mentioned above, it cannot be worn all day, especially during sedentary periods, i.e. when the knee joint is kept bent beyond 80°
In fact, in this position, the force exerted by the orthosis on the kneecap can end up causing excruciating pain
In addition, the viscosity of the polymer gel beneath the sleeve exerts shear forces on the skin, which can eventually cause chafing

Embodiment Construction

[0029]Figure 1 to 4 ,Figure 5A with5BA knee orthosis 10 according to one embodiment,image 3 with4The orthosis 10 placed on the lower right limb is shown.figure 1 The orthosis of the flipped configuration is displayed, and the visible surface is intended to contact the skin. The orthosis 10 includes an elastic sleeve 14 and a pad 11 comprising a viscoelastic polymer gel layer, and is attached to the surface of the sleeve 14 to contact the skin. The sleeve 14 is shaped to apply a compressive force on the thigh, knee and legs. To this end, the sleeve 14 has a tubular shape having a variable diameter along the longitudinal direction of the sleeve, which is adapted to the diameter of the lower portion of the thigh, the upper portion of the knee and the upper portion, to obtain the desired compression in these different parts of the lower limb. force. The sleeve 14 is shaped to apply a pressure based on the current standard.

Abstract

The present invention relates to a knee orthosis comprising: a sleeve (14) made of elastic fabric and configured to exert a compressive force on either side of the knee and on the knee; proximal and distal ends Anchors (19a, 19b) for holding the proximal and distal portions of the sleeve in a fixed position on the lower extremity; panels (11, 11') comprising a polymeric material fixed to the inner surface of the sleeve A viscoelastic layer of gel, an annular portion (11a) configured to surround the patella and a distal tongue (11b), the viscoelastic layer having an adhesive property to the skin such that the panel applies to the skin when the leg is extended longitudinally force, to support the kneecap, the sleeve is made of the following fabric pieces: a front piece (17), a back piece (16) and two side pieces (18a, 18b) of the support panel, the back piece and the side piece along the axis have elastic modulus smaller and larger than that of the front panel, respectively.

Description

Technical field[0001]The present invention relates to an orthosis for maintaining a knee. The present invention is particularly limited, but it is suitable for supporting the knee without having to fix the joint. This orthosis can be used to prevent chronic pain, or alleviate mild sprains, or use during trauma recovery.Background technique[0002]There is a knee support or an orthosis that includes "knee pelvis" to ensure support for knee bones, or include a massage pelvis to massage certain muscles. Such an ortholase is described, for example, in U.S. Patent Application Serial 2006 / 0041214, 2010 / 0036303 and 2011 / 0160631. The orthosis described in these documents includes a ring element of a foam or silicone, which is designed to support it around the knee bone.[0003]These orthosis has multiple disadvantages. They are relatively thick and heavier, especially because they are made of knitting machines produced by using only a knitted fabric that cannot be laminated like a woven fabric ...
