Definitions

• the present invention relates to a knee orthosis preventing hyper extension of the knee of a patient. It is well known to immobilize all or part of the leg of a patient suffering from a sprained knee or having undergone an operation of the knee ligaments which requires postoperative immobilization. The immobilization of the knee can not be obtained by the placement of a plaster given its irremovable nature and the inaccessibility of the part of the body located under the plaster during the entire period of immobilization of the latter, it It is well known to use removable orthoses to immobilize the knee and thus avoid its hyper extension.
• removable orthoses can consist, for example, of an immobilizing splint consisting of a rigid shell; this is the case, for example, of French patent FR 2,605,515 describing an immobilizing splint.
• the splint is made of a plastic shell, ABS style or other material, self-hanging, which maintains the rigidity of the apparatus and which is placed around the member thanks to lights which guide self-hanging straps.
• the splint also includes, on its inner wall, a plate made of closed cell polyethylene foam comprising on the face in contact with the inner shell of scraped jersey pressure welded on the foam and on the other face in contact with the patient's skin cotton welded by pressure on said foam.
• This type of orthosis consisting of a rigid shell has the drawback of requiring a large number of different sizes in order to adapt to the different morphologies of the patients. Indeed, these orthoses are difficult to fix on the leg of a patient taking into account the differences in morphology of the patients, and do not hold, the splint tending to slide down, along the leg when the patient is walking In order to remedy this drawback, flexible splints have already been devised, able to be positioned around the knee of a patient; this is the case, for example, of the German patent DE 4,229,044 which describes a kneepad obtained in a flexible material.
• the kneepad is obtained in a room of a flexible material and provided with fastening means such as bands and loops respectively secured to one of the sides of the part so that the kneepad can be fixed around the leg of a patient.
• the central part of the splint includes an elongated hole to allow the passage of the kneecap.
• the kneepad further comprises, on each of the lateral sides of the latter after it is positioned around the knee of a patient, rigid ribs to allow the immobilization of the knee, the loops and the bands of the fixing means being integral with the sleeves in which the whales are positioned.
• this type of orthosis covers, in addition to the knee with the exception of the kneecap, the lower thigh and the upper calf of the patient, preventing the skin of these parts of the body from breathing which, when summer temperatures, increases perspiration and delays good healing of a possible wound.
• this type of orthosis is used for post-operative immobilizations such as immobilization after an operation of the knee ligaments for example, bandages and bandages are daily applied to the knee substantially increasing the transverse dimension of the limb so that the shell of the orthosis can no longer go around, which has the effect of shifting the relative position of the stiffening whales relative to their normal area of application against the leg, thereby reducing the effectiveness of these orthotics.
• the envelope is composed of at least two padded elements constituting waders, leggings or ankles, capable of encircling a part of the member on either side of the zone to be immobilized and comprising, each, an external face with loops and, at one of their transverse ends, at least one transverse and internal strip of velvet with hooks or pins capable of cooperating with the aforementioned loops to immobilize the envelope element on the member.
• the stiffening ribs are distributed, on the one hand, in two lateral and removable ribs, each composed of at least one rib arranged in a closed sheath, the internal face of which faces the elements of the envelope is provided , over all or part of its length, of hooked or studded velvet capable of cooperating with the loops of the envelope elements, and, on the other hand, in a removable rear rib, composed of at least one angled rib, the branches, arranged on either side of this elbow, are engaged, at least partially and with the possibility of longitudinal sliding, in the sleeves of two cushions, respectively, upper and lower.
• Each of these cushions comprises, on its internal face, a pile of hook or velvet pile capable of cooperating with the loops of the elements of the envelope, and, fixed on its external face, at least one transverse strap capable of encircling the member and of which, at least one of the ends, is provided with attachment means.
• This type of orthosis although making it possible to solve the problem of the correct positioning of the stiffening whales on a knee provided with a bandage or the like, has the disadvantage of wrapping the lower thigh and the upper calf of the patient thus preventing the skin of these parts of the body from breathing which, during summer temperatures, increases perspiration and delays the good healing of a possible wound.
• a knee orthosis preventing a hyper extension of the knee of a patient comprising at least one rigid preformed splint slightly curved able to be positioned in the hollow of the knee popliteal and compression means for holding said splint in the hollow of the knee popliteal remarkable in that it consists of a central vertical frame comprising at least one sheath capable of accommodating the rigid splint, so-called positioning strips extending transversely on either side of the vertical frame comprising at their free ends fixing means capable of cooperating with complementary fixing means integral with the external face of the strips, said strips having a sufficient length to wrap the patient's leg, at least one secondary splint capable of being fixed on the positioning bands so that it extends generally vertically on the lateral side of the knee, and flexible bands called compression bands extending on either side of the vertical reinforcement by covering the positioning strips, the free ends of the connection strips tention comprising closing means and respectively complementary closing means.
• the orthosis according to the invention only partially covers the knee region thus allowing the patient's skin to breathe and facilitating the positioning of the orthosis on a patient's knee despite the presence of voluminous bandages and bandages around the knee.

• the central vertical reinforcement 1 is obtained in flexible fabric and preferably has an internal face la, that is to say the central vertical reinforcement face 1 coming into contact with the patient's skin, in anallergic padded fabric and a external face 1b comprising loops capable of cooperating with the hooks of attachment means of the loop hook type, that is to say of the Velcro type (registered trademark).
