Abstract

The top zone (C) encloses the patient's thigh, the middle portion (B) engages the calf of the leg and the lowermost portion (A) encloses the foot. The stocking is made of textile threads knitted into an elastic weave which can apply pressure to the leg and the foot. There are different types of knitted pattern in the three zones, applying different amounts of pressure.

Description

cordon de tirage et de sécurité (10).pull and safety cord (10).

La compression par support élastique a prouvé son efficacité.  Compression by elastic support has proven its effectiveness.

Hyperpression veineuse et stase capillaroveinulaire sont des constantes de l'insuffisance veineuse chronique et de ses manifestations cliniques, quelle qu'en soit l'étiologie. Toute insuffisance prolongée de la pompe valvulomusculaire du mollet, fonctionnelle ou organique (dysfonctionnement valvulaire, obstruction des troncs collecteurs, ankylose de l'articulation tibiotarsienne...) entrâîne une augmentation de la pression veineuse à la cheville (normale 35 mmHg), augmentation corrélée avec  Venous hyperpressure and capillaroveinular stasis are constants of chronic venous insufficiency and its clinical manifestations, whatever the etiology. Any prolonged insufficiency of the valvulomuscular pump of the calf, functional or organic (valve dysfunction, obstruction of the trunks, ankylosis of the tibiotarsal joint ...) leads to an increase in venous pressure at the ankle (normal 35 mmHg), correlated increase with

l'importance des signes cliniques.the importance of clinical signs.

Cette hyperpression entrâîne une stase capillaroveinulaire et se traduit par des anomalies microvasculotissulaires. Cette hyperpression associce à l'hyperperméabilité microvasculaire entraine une inondation interstitielle et surcharge les canalicules lymphatiques créant l'_dème. Le gradient de pression transmural (pression résiduelle intravasculaire, pression osmotique tissulaire, pression hydrostatique / pression atmosphérique, pression osmatique plasmatique, pression tissulaire périvasculaire)  This hyperpressure leads to a capillaroveinular stasis and results in microvasculotissular anomalies. This hyperpressure associated with microvascular hyperpermeability leads to interstitial flooding and overloads the lymphatic canaliculi creating edema. The transmural pressure gradient (residual intravascular pressure, osmotic tissue pressure, hydrostatic pressure / atmospheric pressure, osmatic plasma pressure, perivascular tissue pressure)

s'exerce de la lumière microvasculaire vers le milieu interstitiel.  is exerted from the microvascular light towards the interstitial medium.

La pression externe exercée par le bas sur la surface cutanée et transmise aux tissus, s' oppose aux pressions intravasculaires, venant s ' aj outer à la pression tissulaire et à la pression atmosphérique à côté des forces de résorption. Outre cet effet direct microvrasculotissulaire, la compression a d'autres effets hémodynamiques démontrés. E!le diminue les calibres veineux superficiels et / ou profonds selon la pression appliquée,  The external pressure exerted from below on the cutaneous surface and transmitted to the tissues, opposes intravascular pressures, coming to add to tissue pressure and atmospheric pressure alongside the resorption forces. In addition to this direct microvrasculotissular effect, compression has other demonstrated hemodynamic effects. E! The decreases the superficial and / or deep venous gauges according to the pressure applied,

favori sant la coalescence valvulaire, et el le accroit la vitesse circulato ire de retour.  favorite for valvular coalescence, and it increases the return circulatory speed.

Pour la dynamique veineuse, la pompe musculaire n'agit que dans la mobilisation, elle est inopérante lorsque les muscles sont en complet relâchement. C'est la succession des contractions-relaxations des muscles squelettiques, imprimant d'importantes variations de volume et de pression aux veines qui les traversent, qui rend efficace la chasse veineuse; le jeu valvulaire assurant la direction centripète du flux. Dans chaque segment de membre, la disposition des veines valvulées par rapport aux muscles et aux aponévroses déterminera le rendement hémodynamique: les plus efEcaces sont les segments veineux intramusculaires, écrasés par tout le tissu environnant (veines jumelles, soléaires, tibiales ou péronières). Les moins efficaces sont les segments veineux entourés de tissus lâches ou non contraints par la contraction musculaire (veines superficielles sus-aponévrotiques,  For venous dynamics, the muscular pump acts only in mobilization, it is inoperative when the muscles are fully relaxed. It is the succession of contractions-relaxations of the skeletal muscles, imparting large variations in volume and pressure to the veins passing through them, which makes venous hunting effective; the valve clearance ensuring the centripetal direction of the flow. In each limb segment, the arrangement of the valvulated veins in relation to the muscles and aponeuroses will determine the hemodynamic efficiency: the most effective are the intramuscular venous segments, crushed by all the surrounding tissue (twin, soleus, tibia or peroneus veins). The least effective are the venous segments surrounded by loose tissue or not constrained by muscle contraction (super-aponeurotic superficial veins,

veine poplitée...).popliteal vein ...).

- 2 Tous les produits traitants qui existent sur le marché sont conçus pour délivrer à partir d'un tricot identique sur toute la jambe, de fils de grosseurs identiques, d'élasticités  - 2 All the treatment products that exist on the market are designed to deliver from an identical knit all over the leg, of yarns of identical size, elasticity

identiques pour tout le produit une pression différente suivant la zone à comprimer.  identical for the whole product, a different pressure depending on the area to be compressed.

Généralement, ces pressions sont progressives sur le pied, maximal sur le tiers inférieur de  Generally, these pressures are progressive on the foot, maximum on the lower third of

la jambe puis décroissante jusqu'en haut de la cuisse.  the leg then decreasing to the top of the thigh.

Ainsi, tous les produits du marché selon que l'on utilise des fils à allongement long ou court privilégient soit l'effet compressif, soit l'effet contentif. Dans le premier cas, ce type de bas est facile d'utilisation mais beaucoup moins efficace que le produit contentif  Thus, all the products on the market, depending on whether long or short elongation yarns are used, favor either the compressive effect or the contentive effect. In the first case, this type of stocking is easy to use but much less effective than the content product

beaucoup plus difficile d'utilisation.  much more difficult to use.

Pour une même pression, une même classe de contention un bas plutôt compressif  For the same pressure, the same compression class a rather compressive bottom

n'aura pas le même comportement qu'un bas contentif.  will not have the same behavior as a low content.

De plus, cette notion de pression dégressive si elle est nocessaire du fait de l'utilisation de fils identiques sur toute la construction du bas, n'est certainement pas suffisante pour atteindre la pleine potentialité du bandage élastique car elle ne tient pas compte du rôle capital de la pompe du mollet sur le retour veineux et du rôle prépondérant que la contention peut jouer sur cette partie anatomique. Il faut savoir que la compression élastique réalisée à partir du tricot utilisant des fils à allongement long exerce une pression active, permanente, sur la peau comprimée et les tissus sousjacents, que les muscles du mollet soient ou non en activité. La pression exercée n'est pas ou peu modifiée par la contraction surale. La compression élastique s'exerce la nuit comme le jour, au repos  In addition, this notion of degressive pressure if it is necessary due to the use of identical threads on the entire construction of the bottom, is certainly not sufficient to reach the full potential of the elastic bandage because it does not take into account the role capital of the calf pump on the venous return and of the preponderant role that compression can play on this anatomical part. It should be known that the elastic compression produced from knitting using long elongation yarns exerts an active, permanent pressure on the compressed skin and the underlying tissues, whether or not the calf muscles are active. The pressure exerted is not or only slightly modified by the surale contraction. Elastic compression takes place at night and during the day, at rest

comme à la marche.like walking.

La contention délivrce par un tricot peu élastique s'oppose passivement et efficacement au gonflement du segment de membre contenu: il oppose une résistance passive très importante à l'augmentation de volume. Il agit comme un mur, une deuxième aponévrose et s'oppose au développement d'un _dème, au gonflement du muscle lors de sa contraction. Ainsi, un tricot peu élastique n'exerce que très peu de pression sur la peau et les tissus sousjacents lorsqu'il est placé sur une jambe au repos. En revanche, lors des 6 0 contractions de s muscles du mol let, elle exerce une forte pres sion (dite de travai l) qui va considérablement augmenter la puissance de la pompe musculaire du mollet et chasser le sang veineux vers l'oreillette droite. Cette contention sera inopérante la nuit ou au repos, mais très efficace à la marche ou elle augmente l'effet vidange de la pompe musculaire apronévrotique. Mode d' action de la compression pression constante effet tissulaire  The compression delivered by an inelastic knit is passively and effectively opposed to the swelling of the contained limb segment: it opposes a very significant passive resistance to the increase in volume. It acts like a wall, a second fascia and opposes the development of edema, the swelling of the muscle during its contraction. Thus, an inelastic knit exerts very little pressure on the skin and the underlying tissues when it is placed on a leg at rest. On the other hand, during the 60 contractions of the knuckle muscles, it exerts a strong pressure (called work pressure) which will considerably increase the power of the calf muscle pump and drive the venous blood towards the right atrium. This compression will not work at night or at rest, but very effective when walking or it increases the emptying effect of the aproneurotic muscle pump. Mode of action of compression constant pressure tissue effect

décongestionnement en contre-balançant l'hyperpression capillaroveinulaire.  decongestion by counterbalancing the capillaroveinular hyperpressure.

Mode d'action de la contention pression lors de la contraction musculaire effet hémodynamique diminution de la stase par augmentation de la vitesse circulatoire  Mode of action of pressure compression during muscle contraction hemodynamic effect decrease in stasis by increase in circulatory speed

Notre invention propose en plus des effets directs d'une pression dégressive ou non, transmise (habituellement par un tricot identique sur toute la longueur de la jambe): de potentialiser au maximum les effets de ces pressions par le jeux de tricots d'élasticités différentes, tour à tour très élastique peu élastique, élastique afin d'associer positivement les effets compressifs performants aux repos et les effets contentifs plutôt efficaces pendant la marche (pression de travail). De plus cette première partie très élastique va faciliter  Our invention proposes, in addition to the direct effects of a decreasing or non-decreasing pressure, transmitted (usually by an identical knit over the entire length of the leg): to maximize the effects of these pressures by the play of knitted fabrics of different elasticities , in turn very elastic, not very elastic, elastic in order to positively associate the effective compressive effects at rest and the rather effective contentive effects during walking (working pressure). In addition, this very elastic first part will facilitate

l'enfilage du produit.threading the product.

Cette invention tient compte de: - la physiologie du retour veineux, - du comportement physique sur le membre des tricotages suivant qu'ils sont élastiques ou moins élastiques. En effet, un tricot très élastique dit compressif va délivrer en permanence une pression donnée sur le membre par contre cette pression varie peu pendant la marche étant donnée la déformabilité due à l'élasticité. A contrario, un tricot peu élastique dit contentif délivre une pression initiale peu importante par contre, lors de toute augmentation de volume du membre par le simple fait de son inélasticité, de sa non déformabilité, la contention exerce une contrepression équivalente à celle exercée par le membre lui-même. Elles s'exercent lors de la marché et potentialisent l'effet de  This invention takes into account: - the physiology of the venous return, - the physical behavior on the member of the knits according to whether they are elastic or less elastic. Indeed, a very elastic knit called compressive will permanently deliver a given pressure on the member against this pressure varies little during walking given the deformability due to elasticity. Conversely, a knitted fabric that is not very elastic and is said to be contentive delivers an initial pressure that is not very significant, however, during any increase in volume of the member by the simple fact of its inelasticity, of its non-deformability, the compression exerts a counterpressure equivalent to that exerted by the member himself. They are exercised during the market and potentiate the effect of

vidange de la pompe musculaire aponévrotique.  emptying of the fascial muscle pump.

Notre invention consiste en tenant de la physiologie du retour veineux de tricoter nos bas en plusieurs parties totalement différentes suivant qu' il est nécessaire d' avoir des pressions plutôt obtenu à partir de tricot élastique compressif pour être efficace au repos, soit des pressions obtenues avec des tricots peu élastique contentif pour être efficace pendant la marche. Ainsi, notre tricotage sera élastique sur le pied et le tiers inférieur de la jambe siège des oedèmes cette pression constante en toute situation y compris au repos  Our invention consists in taking from the physiology of the venous return to knit our stockings in several totally different parts depending on whether it is necessary to have pressures rather obtained from elastic compression knitting to be effective at rest, ie pressures obtained with low elastic knitwear to be effective while walking. Thus, our knitting will be elastic on the foot and the lower third of the leg seat edema this constant pressure in any situation including at rest

aura pour but de lutter efficacement contre l'_dème.  will aim to fight effectively against the edema.

Dès la base du mollet ce tricot change pour devenir contentif jusqu'en haut du mollet. Ce tricot peu déformable va offrir une résistance passive très importante à - 4 l'augmentation du vo lume du mol let pendant la marché ce qui va cons idérab lement augmenter la puissance de la pompe musculaire du mollet et chasser le sang vers  From the base of the calf, this knit changes to become contentive up to the top of the calf. This slightly deformable knit will offer a very important passive resistance to - 4 the increase in the volume of the calf during the market, which will in turn increase the power of the muscular pump of the calf and drive the blood towards

l'oreillette droit.the right atrium.

A partir du creux poplité le tricot changera à nouveau pour redevenir compressif jusqu'en haut de la cuisse pour lutter contre la cellutite. Ainsi cette alternance de tricot très élastique, peu élastique et enfin élastique sur des zones clefs optimisent dans toutes les  From the popliteal hollow the knit will change again to become compressive to the top of the thigh to fight against cellutitis. Thus this alternation of very elastic knitting, not very elastic and finally elastic on key areas optimize in all

situations de port de l'invention par le malade l'effet de la compression et de la contention.  situations of port of the invention by the patient the effect of compression and compression.

Ainsi notre invention est efficace jambe au repos ou en activité.  Thus our invention is effective leg at rest or in activity.

Ce système de tricotage alternatif pourra être fabriqué selon les critères de pression dogressifs actuels, ou ne pas l'être car son efficacité est prioritairement définie par la justesse physiologique du système de tricotage à l'élasticité adaptée suivant la zone à comprlmer. Le bas de compression - contention élective caractérisé en ce que les fils utilisés dans les parties a, b, c, sont d'élongation, force de rappel différente et ce, quelque soit la force de ces pressions à partir de 10 mmHg minimum; que ces pressions soient dégressives, ou  This alternative knitting system may or may not be manufactured according to the current pressure criteria, since its effectiveness is primarily defined by the physiological correctness of the knitting system with the elasticity adapted according to the area to be compressed.
