Description

BRIEF DESCRIPTION OF THE FIGURES

[0023] Further features and advantages of the invention will become clear from reading the following detailed description and from studying the attached drawing in which:

[0024] FIG. 1 shows a schematic side view of an orthosis according to the invention;

[0025] FIG. 2 shows a plan view of the orthosis from FIG. 1.

[0026] The figures depict the median transverse plane P.sub.M passing along the main direction X of the orthosis and separating the space, and in particular the ribbed top, into a front part P.sub.AV and a rear part P.sub.AR. A transverse plane is a plane parallel to the general plane of the patient's body in the service position.

[0027] The figures also depict the median longitudinal plane P.sub.L passing along the main direction X of the orthosis and separating the space, and in particular the ribbed top, into a right part P.sub.DR and a left part P.sub.GA. A longitudinal plane is a plane that contains the main direction X and that is perpendicular to the general plane of the patient's body in the service position.

[0028] In the figures, the same references are used to designate identical or functionally equivalent elements.

DEFINITIONS

[0029] The service position of an orthosis corresponds to a position of use, that is to say a position in which it is fitted on a lower limb of a patient who is standing up. [0030] The at rest or flat position of an orthosis is a position in which the orthosis is not being worn, for example before the first use, and extends, seen from the side, in the same way as in the service position, as in FIG. 1. [0031] The pressure exerted at a point by an orthosis is, according to Laplace's law, a pressure referred to as a textile pressure within the meaning of French standard NF G30-102b, inversely proportional to the radius of curvature at this point. [0032] The altitude corresponds to a level in the vertical direction V (shown in FIG. 1) in the service position. A height is a difference in altitude. [0033] A stitch is a way of interlacing the knit and weft threads.

[0034] Unless indicated to the contrary, the dimensions, such as the height, and the positions, such as front, rear, upper or lower, are given with reference to the at rest position.

[0035] Unless indicated to the contrary, having, comprising, including, or variations thereof, correspond to non-exclusive inclusion.

DETAILED DESCRIPTION

[0036] Reference sign 10 designates in a general manner an orthosis according to the invention, extending along the main direction X.

[0037] The orthosis 10, of overall anatomical shape, comprises [0038] a foot part 12 which envelops the foot, extending from the toes as far as the malleoli, covering the instep, [0039] a leg part 14 which is extensible in a longitudinal direction (that is to say in the main direction X) and in the circumferential direction (radial extensibility), extending from the malleolar region, enveloping the ankle and the calf, up to a level situated below the knee; and [0040] a ribbed top 16 extensible mainly in the circumferential direction, typically a knitted part.

[0041] An orthosis according to the invention, as shown in FIG. 1, takes the form of a knee-high sock, referred to as knee-length or half-stocking in the AD format, meaning that the ribbed top reaches to just below the knee when the orthosis is in the service position. Outwardly, it therefore has the same appearance as traditional fashion socks, but differs from these in terms of the choice of thread and a knit that allows effective therapeutic compression to be obtained, preferably compression of class II.

[0042] The orthosis 10 can be without a foot part 12 (stocking or hose of the open foot type).

[0043] The orthosis 10 is conventionally made from a knitted stitch and, in the leg part, incorporates an elastic weft thread, generally made of a covered elastane.

[0044] The nature of the threads and the stitches used are adapted depending on the action and the appearance that are desired for the different parts of the orthosis. This adaptation does not pose any particular difficulty to a person skilled in the art.

[0045] The ribbed top 16 continues the leg part 14 and, in the service position, forms a substantially cylindrical belt, preferably of constant height H.

[0046] The opening 38 of the orthosis is delimited by a rim 35, which is defined by the ribbed top and the tab and which extends in the continuation of the ribbed top.

[0047] The height H of the ribbed top 16 is preferably more than 2.0 cm, preferably more than 3.0 cm, preferably more than 4.0 cm, and/or preferably less than 8 cm, preferably less than 6 cm, preferably less than 5 cm.

[0048] The outer face of the ribbed top 16 preferably has ribs 40.

[0049] Preferably, the ribbed top 16 is knitted in continuity with the leg part 14. In one embodiment, the only difference between the leg part and the ribbed top of the ribbed top lies in the stitch.

[0050] The tab 34 protrudes upward from the upper edge 36 of the ribbed top 16.

[0051] The maximum height h of the tab 34, measured from the upper edge 36, is preferably more than 0.5 cm, preferably more than 0.8 cm, preferably more than 1 cm, and/or preferably less than 3 cm, preferably less than 2 cm.

[0052] The height h is preferably substantially constant along the entire length of the tab 34.

[0053] The maximum length/of the tab 34 is preferably more than 1 cm, preferably more than 2 cm, preferably more than 3 cm, and/or preferably less than 8 cm, preferably less than 5 cm, preferably less than 4 cm.

[0054] The maximum thickness of the tab 34 is preferably more than 0.5 mm and/or preferably less than 5 mm, preferably less than 3 mm, preferably less than 2 mm.

[0055] Preferably, the thickness of the tab 34 is substantially constant. Preferably, the thickness of the tab 34 is substantially equal to the thickness of the ribbed top. Preferably, the border between the tab 34 and the ribbed top 16 has no discontinuity, such that this border is smooth to the touch.

[0056] The structure, in particular the stitch, of the tab 34 can be identical to or different than that of the ribbed top 16.

[0057] The tab 34 can be knitted and have a network of stitches that are produced by means of a stitch thread and a weft thread interlaced between said stitches.

[0058] The stitch thread of the tab can be identical to or different than the stitch thread of the ribbed top 16.

[0059] The weft thread of the tab can be identical to or different than the weft thread of the ribbed top 16.

[0060] Preferably, the weft thread of the tab 34 is a covered thread, preferably a double-covered thread.

[0061] Preferably, the linear density of the core of the weft thread of the tab 34 is below 150 dTex, preferably below 140 dTex, preferably below 135 dTex, and/or above 100 dTex, preferably above 110 dTex, preferably above 120 dTex, preferably above 125 dTex.

[0062] Preferably, the linear density of the covering thread of the weft thread of the tab 34 is below 40 dTex, preferably below 30 dTex, preferably below 25 dTex, and/or above 10 dTex, preferably above 15 dTex, preferably above 20 dTex.

[0063] Preferably, the tab 34 is knitted in continuity with the ribbed top 16, preferably by augmentation or diminution.

[0064] Preferably, the tab 34 is preferably configured in such a way as to bear elastically on the lower limb of the patient in the service position.

[0065] The tab 34 can also be added on, preferably sewn onto the ribbed top 16. However, the tab 34 is preferably fixed such that it protrudes from the upper edge 36 of the ribbed top 16 at rest and in the service position, unlike a label in particular.

[0066] The tab is preferably knitted, but it can also be of any other material compatible with contact with the skin, for example a biocompatible polymer material.

[0067] In one embodiment, the tab 34 has the same color, preferably the same appearance, as the ribbed top 16. The border between the ribbed top 16 and the tab 34 can be invisible. This makes the tab more discreet.

[0068] In one embodiment, the tab 34 has an appearance differing from the ribbed top 16 and making it more visible. This can improve the originality of the orthosis.

[0069] In one embodiment, the tab 34 carries information, for example concerning the brand and/or the size and/or the date of production of the orthosis, and/or concerning the manufacturer and/or distributor of the orthosis.

[0070] The particular appearance of the tab 34 can thus serve as a unique identifier for all the orthoses of a range of orthoses, or for a specific size, irrespective of the particular orthosis range of a manufacturer, or for all the orthoses of a manufacturer.

[0071] In one embodiment, the tab 34 carries a microchip.

[0072] The information and/or the microchip are/is preferably carried on the inner face of the tab 34, that is to say on that part of the tab which, in the service position, is oriented toward the patient's skin or is even in contact with the patient's skin. Preferably, the information and/or the microchip are/is carried exclusively on the inner face of the tab 34.

[0073] Preferably, the orthosis has fewer than four, preferably fewer than three, tabs 34, preferably a single tab 34.

[0074] Preferably, a tab 34 is arranged at least partially, preferably completely, on the rear part P.sub.AR of the ribbed top.

[0075] Preferably, a tab 34 is arranged in such a way as to bear, in the service position, on the patient's calf, preferably on the rear part of the patient's calf, preferably elastically.

[0076] Discreetness and comfort are improved in this way.

[0077] Preferably, a tab 34 is arranged in such a way as to be centered on the median longitudinal plane P.sub.L.

[0078] Preferably, a tab 34 is arranged in the rear part of the orthosis, remote from the foot part 12.

[0079] The position, structure and size of the tab 34 make it easy for the patient to grip. The patient can thus easily widen the opening of the orthosis when putting the latter on. He can also more easily grasp the upper part of the orthosis in order to take the latter off.

[0080] Of course, the invention is not limited to the embodiments described and shown, which have been provided only for illustrative purposes.

[0081] In particular, the tab can have shapes other than the tongue shape shown, although the latter constitutes a preferred embodiment.

[0082] The tab can also be fixed on the outer face of the ribbed top, that is to say on the face opposite the face in contact with the patent's skin in the service position.
