    TECHNICAL AREA
    The present invention relates to the field of medical splints. It relates to a wrist-rail according to the preamble of claim 1.
    STATE OF THE ART
    An example of a wrist splint is the carpal tunnel orthosis described in document EP 0 916 325 A1. In the case of the so-called carpal tunnel syndrome (CTS), there is tingling sensation, sensory disturbances and pain of the thumb, the index finger and the middle finger of the affected hand due to nerve entrapment in the carpal region. A possible therapy is the immobilization of the wrist with a wrist splint, a so-called carpal tunnel orthesis, as described in EP 0 916 325 A1. Such orthoses are fixed by means of flexible straps on the forearm and on the hand. In this case, either rigid pre-bent or bendable straps and / or holding devices with plastic and / or metal inserts or straps made of textile materials are used, which can usually be combined with Velcro fasteners. EP 0 916 325 A1 uses a single rail element running on the upper side of the hand and forearm.
    The document DE 4 326 751 A1 discloses a hand and wrist orthosis of a bandage-like support body which is fixable by means of fastener tapes on the hand and on the wrist and in which a single volar rail is incorporated, in particular for the treatment of tendovaginitis. The orthosis consists of a form-sewn wrist and hand envelope-like enclosing supporting body, which ends with a hand side cross-section in the region of the proximal phalanx, and from a volarseitig arranged on the inner wall surface of the support body spoon-shaped, the palm-supporting and the pointed handle enabling rigid rail in the Has area of the phalanges and metacarpals three mutually bent rail sections with very specific angular positions to each other.
    The document EP 1 452 154 A2 describes an orthosis with at least one tether which is intended for application to the body of a patient, in particular to the arms or legs of a patient. The tether has a prestressed, profiled metal rail which is designed so that the tether can change following the bias of the metal rail from a first extended position to a second position adjacent the patient's body. The prestressed profiled metal rail is preferably made of spring steel, hard-rolled aluminum or beryllium bronze. In particular, the carpal tunnel orthosis has two part-circular holding straps with preloaded profiled metal rails for flexible molding on a forearm of a patient, which are arranged on a rigid rail, which is intended to rest on the inside of the arm. The rigid rail has at one end region a first transverse to the rail tether and approximately in the middle a second transverse to the rail tether, wherein in the second end region a fastening possibility for a running around the palm of the flexible retaining band is provided.
    The document EP 1 894 546 A1 discloses a wrist orthosis with a rail having at least one arm region and a hand region, wherein the arm region of the rail rests against the side of the forearm at least at the area of the forearm which is remote from the trunk, which in the anatomical normal position of the Armes of the fuselage center plane faces, and the hand region of the rail at least partially against the palm, wherein the side of the rail, which is located with respect to the forearm on the side of the ulna, and on the side of the rail, with respect to the forearm on the side the spoke is arranged, at least three wing-like sections are arranged, of which at least two are arranged on the arm so as to encompass the forearm that the forearm is at least partially encompassed both ellenseitig and spoke side of the wing-like sections, wherein at least one wing-like section on the hand area the Hand ellenseiti g at least partially encompasses.
    The document US 5 409 451 shows a deformable one-piece wrist splint which extends between the forearm and the hand for fixation of the wrist. The splint consists of a flexible, cut plate having a central volar longitudinal portion terminating in a palmar support, a pair of transversely extending forearm gripping arms extending from the forearm end of the splint, a pair of transversely extending wrist gripping arms extending from the central portion of the rail, a pair of transversely extending palm gripping arms; which extend to opposite sides of the palm just above the palmar support, and an integral outer layer on one side of the plate and a liner applied on the opposite side of the plate.
    The document US 6 106 492 discloses a carpal tunnel rail, which can be adapted to the supporting hand and wrist of each patient. The splint comprises an elongated, narrow and pliable inner cushioning layer conforming to the shape of the hand and wrist, an initially flexible intermediate layer over the inner cushioning layer, and an intermediate layer comprising a moisture-soaked resin soaked fabric, which conforms to the Curing maintains its shape, in which it has been brought during curing, so that the flexible inner padding layer is held in this form against the hand and wrist.
    All known wrist-rails are either very complicated, lead due to a much simplified structure only to a limited fixation, or are inconvenient to wear due to lack of adaptability.

    BRIEF EXPLANATION OF THE FIGURES
    The invention will be explained in more detail with reference to embodiments in conjunction with the drawings. Show it:<Tb> FIG. 1 <SEP> in the plan view from the outside (a) and in cross-section (b) an embodiment of a wrist splint according to the invention;<Tb> FIG. 2 <SEP> in plan view from above a wrist splint according to FIG. 1 in the application on a wrist; and<Tb> FIG. 3 <SEP> the applied wrist-rail of Fig. 2 in plan view from below.
    WAYS FOR CARRYING OUT THE INVENTION
    Fig. 1 shows in plan view from the outside (Fig. 1a) and in cross-section (Fig. 1b) an embodiment of a wrist splint or carpal tunnel syndrome (CTS) -thesis according to the invention. The wrist rail 10 of Fig. 1 has a rail body 11 in its non-applied and fitted initial shape, which has the shape of an approximately rectangular, thin, flat plate.
    The wrist rail 10 has a rail longitudinal direction 34 (Fig. 1a), which is oriented with applied rail approximately parallel to the longitudinal direction of the lower arm (22 in Fig. 2). By an eccentrically arranged, extending in the rail longitudinal direction 34 recess 13 two strip-shaped rail sections 14 and 15 are defined in the rail body 11, which also extend in the rail longitudinal direction 34 and are indicated in Fig. 1a by dashed edge lines. By the recess 13 are also defined a front connecting web 16 and a rear connecting web 17, through which the rail sections 14, 15 are each firmly connected at their end. The front connecting web 16 extends transversely over the back of the hand with the rail (FIG. 2) applied, while the rear connecting web 17 is located in the region of the lower arm 22 (FIG. 2).
    The dimensions of the rail body 11 and the wrist rail 10 are chosen so that when creating the rail to a wrist to the end line of the middle hand, the configuration illustrated in Figs. 2 and 3 forms. In this configuration, the first rail portion 14 extends longitudinally of the forearm 22 from the forearm 22 over the wrist along the edge of the hand to the end line of the middle hand, being molded to the hand edge so as to engage the hand edge. The second rail section 15 extends in the longitudinal direction of the lower arm 22 in extension of the spoke (radius) 33 of the forearm 22 from the forearm 22 via the wrist and the back of the hand to the end line of the middle hand. The orientation of the second rail section 15 is ideally such that, according to the dot-dash line drawn in FIG. 2, it "lengthens" the spoke 33 and "connects" it approximately with the metacarpal bones of the middle finger 27.
    In the front region of the rail body 11 at the front end of the first rail portion 14, a laterally outwardly projecting tab 12 formed with an arcuate outer edge, which supported by the rail (Fig. 3) on the palm 24 in the area of the small finger barb (Hypothenar) is applied.
    Due to the double-connected rail sections 14 and 15 and the tab 12, the wrist is optimally fixed relative to the forearm 22, without the mobility of the thumb 25 and the individual fingers 26-29 would be limited in any way. The recess 13, which may also be closed with an air-permeable fabric layer or the like., Increases the comfort, because only necessary for im mobilization of the wrist parts of the forearm and the hand are covered by the rail. In addition, the wrist rail 10 is advantageously provided with the rail body 11 distributed over the surface arranged ventilation holes 18, which provide additional air exchange between the skin and the environment.
    The attachment of the wrist-rail 10 on the wrist takes place at three different locations, which are arranged at a distance in the rail longitudinal direction 34 one behind the other, by three fasteners 30, 31 and 32. The rear fastener 30 is attached to the forearm before the wrist and partially covers the rear connecting web 17 of the wrist rail 10 and is also fixed there (FIG. 2). The middle fastening element 31 is mounted in the region of the wrist and, as shown in FIG. 3, is fixed with the ends next to one another on the first rail section 14 (FIG. 3). The front fastening element 32 extends transversely across the palm of the hand 24 and partially the back of the hand and partially covers the front connecting web 16 of the wrist-rail 10 and is also fixed there.
    The fasteners 30, 31 and 32 are formed as elongated strips and consist of a material that is similar to the material of the wrist-rail 10 in itself stiff, but adaptable to the wrist. When the wrist splint 10 is applied and fixed (FIGS. 2 and 3), the fastening elements 30, 31 and 32 around the forearm 22, wrist and hand 23, unlike the conventional straps, form dimensionally stable rings which additionally contribute to the fixation of the wrist , As a material of the fasteners 30, 31, 32 is especially a non-längsdehnbares, wavy in the strip longitudinal direction aluminum sheet in question, as is known from another disclosure of the applicant, WO 2011036054 A1. All there regarding the fixing made material and configuration information as well as attachment options by means of Velcro and the like. Can be used for the fasteners 30, 31 and 32 of the present wrist-rail application. But it can also be used not wavy aluminum sheet. However, it is also conceivable to use other materials, such as e.g. deformable plastics or other metals to produce similar properties.
    As already mentioned, the rail body 11 consists of an adaptable to the arm and hand of the patient rail material. This rail material of the rail body 11 is, as shown in the embodiment of Fig. 1b, advantageously multilayer structure and includes a rail core 20, which consists of an adaptable to the arm and hand of the patient core material. The rail core 20 is provided on the outside and / or inside with a cover layer 19 and 21, respectively. The outer cover layer 19 may consist of a foamed, preferably washable material. The inner cover layer 21 may be formed, for example, as a skin-compatible tissue or the like. Other materials for the cover layers are conceivable without further ado.
    As a material for the rail core is in particular a corrugated parallel to the rail longitudinal direction aluminum sheet with a thickness in the range of about 0.6 mm into consideration. Again, other materials are conceivable, so that, for example, the rail core 20 consists of a thermoplastic material, which is adapted to the wrist in the heated state and ensures a dimensionally stable fixation of the wrist after cooling.
