Abstract
Description
L'insuffisance veineuse des membres inférieurs est due à une anomalie du retour veineux. Dans la partie inférieur du corps situé sous le coeur, la pression orthostatique (pression exercée par une colonne d'eau et dépendant de la hauteur de cette colonne d'eau), gène le retour veineux vers le corps. De façon physiologique, pour permettre le_ retour veineux du bas vers le haut et le coeur, il existe deux mécanismes prépondérants au niveau des membres inférieur : Un mécanisme actif lié à la contraction musculaire au niveau du mollet : c'est la pompe du mollet. En se contractant les muscles écrasent le réseau veineux et chasse le sang. The venous insufficiency of the lower limbs is due to an abnormality of the venous return. In the lower part of the body below the heart, the orthostatic pressure (pressure exerted by a column of water and depending on the height of this water column), gene venous return to the body. Physiologically, to allow venous return from the bottom to the top and the heart, there are two dominant mechanisms in the lower limbs: An active mechanism linked to muscular contraction at the level of the calf: it is the calf pump. In contracting the muscles crush the venous network and flush the blood.
Un mécanisme passif : le réseau valvulaire qui a pour but d'orienter le flux sanguin généré par la pompe musculaire du mollet, du réseau veineux superficiel vers le réseau veineux profond (valvules ostiales), puis d'orienter le flux sanguin du bas vers le haut. A passive mechanism: the valve network which aims to direct the blood flow generated by the muscular pump of the calf, the superficial venous network towards the deep venous network (ostial valves), then to direct the blood flow from the bottom to the high.
La maladie variqueuse des membres inférieurs est la conséquence d'un dysfonctionnent de 15 ces systèmes. La compression des membres inférieurs par des tissus médicaux élastiques a montré depuis longtemps son efficacité sur l'insuffisance veineuse des membres inférieurs. The varicose disease of the lower limbs is the consequence of a dysfunction of these systems. The compression of the lower limbs by elastic medical tissues has long shown its effectiveness on venous insufficiency of the lower limbs.
Sous forme de chaussettes, bas cuisses ou collants, ces tissus médicaux exercent une pression 20 sur le membre inférieur. La pression n'est pas uniforme. Il existe un gradient de pression du bas vers le haut, les plus hautes pressions étant au niveau de la cheville puis les pressions décroissent en montant vers la racine du membre inférieur. Ce gradient de pression améliore le retour veineux de plusieurs façons : - compression du réseau veineux superficiel dilaté, 25 diminution de l'oedème interstitiel, réorientation du flux veineux, du réseau veineux superficiel vers le réseau veineux profond, - réorientation du flux veineux du haut vers le bas. In the form of socks, thighs or pantyhose, these medical tissues exert pressure on the lower limb. The pressure is not uniform. There is a pressure gradient from the bottom to the top, the highest pressures being at the level of the ankle and the pressure decreases going up to the root of the lower limb. This pressure gradient improves the venous return in several ways: compression of the dilated superficial venous network, reduction of interstitial edema, reorientation of the venous flow, of the superficial venous network towards the deep venous network, reorientation of the venous flow from the top down.
30 Ce gradient de pression améliore ainsi l'effet physiologique de pompe musculaire du mollet et du réseau de valvule présent au niveau de la paroi des veines. -2- Le cahier des charges pour la fabrication de tels produits est. parfaitement codifié. Pour être remboursé par la Sécurité Sociale, le cahier des charges est particulièrement strict. This pressure gradient thus improves the physiological effect of muscular pumping of the calf and the valve network present at the level of the wall of the veins. -2- The specifications for the manufacture of such products is. perfectly codified. To be reimbursed by Social Security, the specifications are particularly strict.
Toutefois, deux types de fils peuvent être utilisés à condition de respecter le cahier des 5 charges sur le gradient de pression exercé au niveau du membre inférieur : des fibres très élastiques à effet compressif, des fils beaucoup moins élastiques à effet contentif. However, two types of son can be used, provided that the specifications for the pressure gradient exerted on the lower limb are complied with: very elastic fibers with a compressive effect, and much less elastic threads with a protective effect.
Les fils élastiques exercent un effet compressif dynamique ou actif. Lors de la contraction 10 musculaire, les fibres du tissu étiré vont exercer une pression d'autant 'plus importante sur le tissu musculaire que ces fibres sont étirées. Les produits ainsi obtenus sont très étirables, faciles à enfiler. Mais au repos, les pressions exercées sont moindres. Elastic threads exert a dynamic or active compressive effect. During muscle contraction, the fibers of the stretched tissue will exert a greater amount of pressure on the muscle tissue as these fibers are stretched. The products thus obtained are very stretchable, easy to put on. But at rest, the pressures exerted are less.
15 Les fibres à effet contentif ont une action plutôt passive. Elles sont peu extensibles et font l'effet d'une boîte inextensible lors de l'effort. Le muscle qui se contracte ne peut se dilaté en largeur puisqu'il est entouré d'une enveloppe peu étirable, ce qui oriente le flux vasculaire vers le haut. Les produits obtenus avec ces fils sont peu étirables et exercent une pression importante 20 même au repos. Containing fibers have a rather passive action. They are not very extensible and have the effect of an inextensible box during the effort. The contracting muscle can not expand in width as it is surrounded by a loose envelope, which directs the vascular flow upwards. The products obtained with these yarns are not stretchable and exert a significant pressure even at rest.
Habituellement, les deux types de fils ne sont pas utilisés dans un même produit. Usually, both types of wires are not used in the same product.
Si l'amélioration du retour veineux a un effet bénéfique en pathologie, elle peut aussi être 25 intéressante chez le sportif. While improving venous return has a beneficial effect in pathology, it may also be of interest to the athlete.
Même si la littérature scientifique est encore peu fournie, plusieurs études confirment un effet bénéfique de la compression veineuse chez le sportif. Deux champs d'utilisation sont possibles : 30 - amélioration de la performance durant l'effort. L'amélioration du retour veineux permet une amélioration de l'oxygénation des tissus, une diminution du stockage de produit de dégradation nocif à l'intérieur du muscle (acide lactique) et une diminution de l'oedème interstitiel. De façon théorique, l'amélioration du retour veineux pourrait -3- augmenter le débit cardiaque et ainsi la V02 max. Pour une contention standard, les preuves scientifiques de l'amélioration des performances chez le sportif manquent toutefois. favorisation de la récupération entre deux périodes d'effort. L'amélioration du retour veineux éviterait la stagnation de produits de dégradation générés par l'effort au sein du muscle comme l'acide lactique et des agents oxydants qui entraîneraient crampes, sensation de lourdeur ou courbatures. Cet effet de purge évite aussi un effet hyperosmolaire des produits de dégradation, cause d'oedème. Cet aspect récupération est de plus en plus pris en compte chez les sportifs qui 10 multiplient massages drainant après effort, bains glacés au niveau des membres inférieurs. Il existe déjà des produits compressifs des membres inférieurs utilisés par les sportifs, soit pour améliorer les performances, soit pour favoriser la récupération. Although the scientific literature is still scarce, several studies confirm a beneficial effect of venous compression in athletes. Two fields of use are possible: 30 - improvement of the performance during the effort. The improvement of venous return allows an improvement of the tissue oxygenation, a decrease of the storage of harmful degradation product inside the muscle (lactic acid) and a decrease of the interstitial edema. In theory, improved venous return could increase cardiac output and thus max V02. For a standard contention, however, the scientific evidence of improved athletic performance is lacking. favoring recovery between two periods of effort. The improvement of venous return would avoid the stagnation of degradation products generated by the effort in the muscle such as lactic acid and oxidizing agents that would cause cramps, feeling of heaviness or stiffness. This purging effect also avoids a hyperosmolar effect of the degradation products, causing edema. This aspect of recovery is increasingly taken into account among athletes who multiply draining massage after effort, cold baths in the lower limbs. There are already lower extremity compressive products used by athletes, either to improve performance or to promote recovery.
15 Le premier but de notre brevet est d'améliorer les performances du drainage veineux en associant dans le tissage de chaussettes, bas, mi-bas ou bas, des fibres à effet compressif et des fibres à effet contentif. Par l'association des deux types de fibres tissées selon un cahier des charges bien défini, nous augmentons fortement l'efficacité du système contentif sur le retour veineux. 20 Selon l'invention, ce bas comprend trois zones bien définies : une première zone rigide (N°1) qui s'appuie sur l'arête tibiale, s'étendant de la pointe de la rotule jusqu'à la base du tibia et se prolongeant de chaque côté de la cheville pour assurer un rappel proprioceptif et une stabilité de la cheville. Une seconde zone aussi très rigide (N°3) encadrant de haut en bas totalement la 25 pompe du mollet afin de la contraindre au moment de l'effort et de son développement. Cette zone encadrera également le tendon d'Achille afin de le protéger et de l'empêcher de vibrer. - Entre ces deux zones (N°1 et 3), une troisième zone très élastique (N°2) avec un fort pouvoir de rappel afin de créer un « effet soufflet » qui décuple la puissance de la 30 pompe musculaire du mollet. The first object of our patent is to improve the performance of venous drainage by combining in the weaving of socks, low, mid-low or low, compressive and compressive effect fibers. By combining the two types of woven fibers according to well-defined specifications, we greatly increase the efficiency of the venous return system. According to the invention, this bottom comprises three well-defined zones: a first rigid zone (No. 1) which rests on the tibial edge, extending from the tip of the patella to the base of the tibia and extending on each side of the ankle to provide proprioceptive recall and stability of the ankle. A second very rigid zone (No. 3) flanking the calf pump from top to bottom in order to constrain it at the time of the effort and its development. This area will also frame the Achilles tendon to protect it and prevent it from vibrating. - Between these two areas (No. 1 and 3), a third highly elastic zone (No. 2) with a high power of return to create a "bellows effect" which increases the power of the muscular pump 30 calf.
Le deuxième but de notre brevet est d'offrir au niveau de la cheville, un renfort des structures ligamentaires de la cheville et une stabilisation du tendon d'Achille. Ce sont les fibres peu 2958535 -4- élastiques latérales situées au niveau du mollet qui viennent stabiliser latéralement la cheville et le tendon d'Achille. L'effet attendu est une diminution des entorses et des micro-traumatismes des ligaments de la cheville et du tendon d'Achille. The second aim of our patent is to offer ankle reinforcement of the ligamentous structures of the ankle and stabilization of the Achilles tendon. It is the little lateral elastic fibers located at the level of the calf which laterally stabilize the ankle and the Achilles tendon. The expected effect is a decrease in sprains and micro-traumatisms of the ligaments of the ankle and Achilles tendon.
