    The present invention relates to the field of compressive orthoses more commonly known as compression stockings.
    The present invention relates to a compression stocking with distinct circumferential compression zones.
    The term "down" any compression article used for the lower limbs such as socks, tights, tapes.
    It is known that a compression stocking is a stocking having sufficient elasticity to compress the lower limbs of a user and replacing the deficiency of the venous walls. Venous compression increases the speed of venous flow by an increase in venous pressure, when in some postures of the user it is low or almost nonexistent.
    Currently there are compression stockings for medical use, especially in the treatment against venous insufficiency and compression stockings for non-medical use including to improve blood circulation during and after a sporting effort.
    The pressure exerted by the lower limbs must be adapted to the use. Indeed, compression stockings for medical use often exert a high compression and high degression, that is to say a different pressure at both ends and with a very large pressure difference, to boost the circulation of blood that is defective. The term degressivity means any pressure decrease from a distal point, here the ankle or malleolus to a proximal point, here the popliteal fossa.
    Such compression on the lower limbs is not recommended for users without venous problems, including some athletes, who use compression stockings during the effort to accelerate the oxygenation of the blood and thus improve their performance sports, but also after the effort, during the recovery time, to evacuate accumulated toxins and prevent muscle cramps.
    [0008] If the pressure is too great or if there is a strong degressivity of compression on the lower limbs of a user who does not have a venous problem, this can cause discomfort or a feeling of ping in the foot and in the most extreme cases, venous reflux is impossible, leading to tissue hypoxia.
    [0009] On the other hand, if the compression is too weak or non-existent, the "muscular pump" effect of the lower limbs may be insufficient or non-existent, thus causing venous stasis.
    In order to avoid too much compression degression at the lower limbs, there are compression stockings with different compression zones.
    However, in trying to remedy the high degression, the decrease in the pressure difference at the ends is not sufficient, which often causes a feeling of discomfort in the toes and in the regions of the ankle, the compression has become too weak to exert sufficient pressure then causing venous stasis.
    The present invention aims to overcome these disadvantages by providing a compression stocking with circumferential compression zones for recovery after the effective effort and providing a variation of pressure throughout the lower limbs by a gradual degression n ' causing neither discomfort nor discomfort and allowing a better circulation of the blood to avoid venous stasis.
    For this purpose, the subject of the present invention is a compression stocking comprising, in a normal condition of use, that is to say when it is normally worn by the user, a closed lower end corresponding to the housing. toes of the user and an upper end emerging at the popliteal fossa, below the knee, characterized in that it has at least three distinct circumferential compression zones, at least two of which are zones of different compression, the first compression zone corresponding to the area surrounding the ankle, at the level of the malleolus, the second and third compression zone extending on either side of said first compression zone and respectively the upper end of said first compression zone to said upper end emerging from said compression stocking, and said lower end of the adite first compression zone to the closed lower end of said compression stocking.
    The invention will be better understood, thanks to the following description, which refers to preferred embodiments, given by way of non-limiting example, and explained with reference to the accompanying diagrammatic drawings, in which:<tb> Fig. 1 <SEP> represents a side view of the compression stocking according to the present invention,<tb> fig. 2 <SEP> represents a side view of the compression stocking according to a variant of the present invention, and<tb> fig. 3 <SEP> represents a side view of the restraining elements of the variant shown in FIG. 2.
    As shown in particular in FIG. 1, the present invention consists of a compression stocking 1 which may comprise, in normal use condition that is to say when it is normally worn by the user, a closed lower end 2 corresponding to the housing of the toes of the user and an upper end emerging 3 at the popliteal fossa, below the knee. The compression stocking 1 according to the present invention may have at least three distinct circumferential compression zones 4, 5 and 6, at least two of which are different zones of compression, the first compression zone 4 corresponding to the zone surrounding the ankle. at the level of the malleolus, the second and third compression zone 5 and 6 extending on either side of said first compression zone 4 and respectively the upper end 4 of said first compression zone 4 until at said upper outlet end 3 of said compression stock 1, and said lower end 4 of said first compression zone 4 to the closed lower end 2 of said compression stocking 1.
    From this advantageous distribution into three distinct compression zones 4, 5 and 6 shown in particular in FIG. 1, the lower limbs of the user are effectively maintained and the pressure exerted in each of the zones 4, 5 and 6 is adapted to the physiognomy of the user, the compression variations along the lower limbs favoring the dynamisation of the circulation some blood.
    Preferably, the first compression zone 4 exerts a different compression pressure compared with the other two compression zones 5 and 6, because it is at the level of the ankle and malleolus that the venous stasis may appear, the blood is subject to gravity and does not necessarily go well in this area.
    According to the present invention, the first compression zone 4 can exert a uniform compression pressure on the lower limbs of the user which is larger than the second or third compression zone 5 and 6.
    High compression at the first compression zone 4 and more particularly at the malleolus, facilitates venous return, decreases venous pressure, prevents venous stasis and effectively relieves sore lower limbs.
    Advantageously, the first compression zone 4 can exert a uniform compression pressure on the lower limbs of the user between 10 and 50 mmHg (ie between 1333 Pa and 6666 Pa), preferably between 20 and 41 mmHg (either between 2666 Pa and 5466 Pa).
    In a preferred embodiment of the present invention, the first compression zone 4 can extend in a region of the ankle comprising the malleolus of the user and which can extend in a direction parallel to the longitudinal axis of the leg of said user at a constant vertical height h of between 3 and 8 cm, preferably equal to 5 cm.
    In order to ensure effective compression during the sporting effort, the second compression zone 5 may exert a constant compression pressure along the latter or degressive starting from the end 4 of the first zone of compression. compression 4 up to the upper open end 3 of the compression stocking 1.
    Constant pressure means a uniform pressure and the same value all along the lower limbs.
    It will be understood by degressivity that the second compression zone 5 may exert a stronger compression pressure at said end 4 of said first compression zone 4 than at said upper outlet end 3 of the compression stocking. 1. This degressivity of pressure in the second zone 5 allows a reduction of gentle pressure, without sudden change that could cause local discomfort.
    According to a variant, the second compression zone 5 may also exert a pressure of between 5 and 30 mmHg (ie between 666 Pa and 4000 Pa), preferably between 10 and 26 mmHg (ie between 1333 Pa and 3466 Pa).
    According to a variant of the present invention and as shown in FIGS. 2 and 3, the compression stocking 1 can result from the partially overlapping assembly of two different and independent compression elements 9 and 10, the first compression element 9 being substantially in the form of a sleeve corresponding to the second compression zone 5 and provided at said upper end 4 with a circumferential extension 7 terminating at said lower end 4, the second compression element 10 being substantially in the form of a sock whose lower part corresponds to the third compression zone 6 and provided at said lower end 4 with a circumferential extension 8 terminating at said upper end 4, the two circumferential extensions 7 and 8 forming the first compression zone 4 of said compression stock 1 when they are completely superimposed.
    In a possible embodiment of the first variant of the present invention, said circumferential extensions 7 and 8 may have fastening means (not shown) for detachably securing them.
    These fastening means allow a removable connection of contact and may be in the form of particular self-gripping tape.
    This configuration in two detachable elements advantageously allows athletes, for example, to wear during the effort only the first contention element 9 shown in FIG. 2, and after the effort, to combine the compression forces of the first and second element 9 and 10 of contention for optimal recovery.
    In addition, for sports, including triathlon, which require the feet without socks or the like to save time in the race, it may be advantageous to wear only the first restraining element 9, to the extent that it does not cause any discomfort since it is in the form of a cylindrical sleeve without a foot provided with a circumferential extension 7.
    Advantageously, the circumferential extension 7 of the first compression element 9 exerts a uniform pressure of between 5 and 30 mmHg (ie between 666 Pa and 4000 Pa), preferably between 10 and 26 mmHg (ie between 1333 Pa and 3466 Pa). .
    According to the present invention, the circumferential extension 8 of the second compression element 10 can exert a uniform pressure of between 5 and 20 mmHg (ie between 666 Pa and 2666 Pa), preferably between 10 and 15 mmHg (ie between 1333 Pa). and 2000 Pa).
    The pressure exerted separately by the circumferential extension 7 and the circumferential extension 8 is cumulative when the superposition of the latter is total. In other words, the total pressure is equal to the sum of the added pressures.
    In a possible embodiment of the present invention, the compression stocking 1 can be made from natural or synthetic fibers, such as nylon or polyamide, for example.
    [0035] Preferably, the nylon that can be used for the manufacture of the compression stocking 1 of the present invention, may correspond to the nylon 6.6 type of the Nilit® Aquarius brand. This type of nylon has many advantages: it is hydrophilic and the trilobal cross-section of the filaments makes it possible to regulate the humidity via micro-channels which evacuate it, out of the body.
    Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
