Definitions

  • the present invention relates to the field of devices for stimulating the plantar venous pump, intended to be used by people whose activity, in certain situations, forces them to remain standing.
  • Stimulation devices including an electrically powered mechanism are already known. These devices are often expensive and unsightly, of a complex and very cumbersome design, and especially operating by means of battery, so as to be of reduced autonomy requiring frequent reloading operations.
  • US 2006/000119 A1 describes a device where the pressure applied against the plantar venous pump is the direct result of the support of the foot on the ground. There is no means of disengaging the movement as long as the heel remains on the ground. For example, when the user is standing (but he is not moving) cushion 2a will always apply constant pressure to the plantar region.
  • the object of the present invention is to remedy the various aforementioned drawbacks, by proposing a device for stimulating the plantar venous pump, the operation of which does not require motorization, and therefore no battery, and which is of a low manufacturing cost. thus making it accessible to many people with blood circulation problems in the lower limbs.
  • the device for stimulating the plantar venous pump according to the invention is characterized in that it is designed able to take place in a shoe, and to remain hidden there, and in that it comprises on the one hand, disposed in the boot in the right place intended to be occupied by the plantar arch, a movable mounted cushion, connected to a motion transmission means, itself linked to an actuator disposed in the heel said shoe, said actuator and said transmission means being adapted to transform the support resulting from the installation of said heel to the ground, into a movement of said cushion to apply a short pressure against the plantar venous pump.
  • the assembly comprising the actuator and the transmission means is designed capable of mobilizing the cushion for a very short time so that said cushion applies a short pressure against the plantar venous pump, and for this purpose it comprises means for disengaging the movement, active beyond a predefined displacement value of the displacement.

  • the actuator comprises a vertically movable element in the heel of the shoe, one end protrudes, directly or indirectly, inside said shoe, while the other end cooperates, through means of return, with the transmission means which consists of a lever.
  • the actuator comprises a movable element vertically in the heel, while the transmission means is movable perpendicularly or substantially perpendicularly to the axis of movement of said actuator.
  • the cushion is moved hydraulically or pneumatically.
  • the transmission means comprises a pump which feeds a jack which mobilizes the cushion, and which is actuated through a mechanism delivering a pulse during the installation of the heel on the ground.
  • This device is, in part, to substitute for walking on the circulatory plan by operating the plantar venous pump by simply pressing the foot on the ground, thus promoting the return of blood to the heart.
  • This device incorporated in the shoe is simple, autonomous, requires no maintenance. It has the advantage of being able to equip almost all models of shoes, classic or modern.
  • This mechanical device applies pressure on the arch at the location of the venous pump. This pressure is simply caused by the support of the heel of the shoe on the ground. The plantar venous pump is thus stimulated, the rise of the blood towards the heart takes place, and activates the blood circulation and thus limits the appearance of various venous problems.
  • This device is particularly intended for all persons standing, walking or stomping, such as traders (hairdressers, vendors behind their counter), staff in the factories in front of the machines. Staff in catering etc.

Description

  • La présente invention concerne le domaine des dispositifs de stimulation de la pompe veineuse plantaire, destinés à être utilisés par les personnes dont l'activité, dans certaines situations, les oblige à rester debout.
  • On sait qu'il existe sous la voûte plantaire un réseau veineux qui, lorsqu'il est comprimé par la marche à pied contribue à renvoyer le sang vers le coeur.
  • On sait également que le manque de remontée de sang dans les veines occasionne une circulation insuffisante dans les jambes et provoque des problèmes veineux, varices, gonflement des chevilles et fatigue dans les jambes.
  • On connaît déjà des dispositifs de stimulation comprenant un mécanisme mû électriquement. Ces dispositifs sont souvent coûteux et peu esthétiques, d'une conception complexe et très encombrante, et surtout fonctionnant au moyen de batterie, en sorte d'être d'une autonomie réduite nécessitant de fréquents opérations de rechargement. US 2006/000119 A1 décrit un dispositif ou la pression appliquée contre la pompe veineuse plantaire est le résultat direct de l'appui du pied au sol. Il n'y a pas de moyens de débrayage du mouvement tant que le talon reste au sol. Par exemple, quand l'utilisateur est debout (mais il ne se déplace pas) le coussin 2a appliquera toujours une pression constante à la région plantaire.
  • Du fait des inconvénients précités, ces dispositifs rencontrent un faible engouement.
  • La présente invention a pour but de remédier aux divers inconvénients précités, en proposant un dispositif de stimulation de la pompe veineuse plantaire, dont le fonctionnement ne nécessite pas de motorisation, et donc pas de batterie, et qui est d'un faible coût de fabrication, le rendant ainsi accessible à de très nombreuses personnes présentant des problèmes de circulation sanguine au niveau des membres inférieurs.
  • Le dispositif de stimulation de la pompe veineuse plantaire selon l'invention se caractérise en ce qu'il est conçu apte à prendre place dans une chaussure, et à y demeurer caché, et en ce qu'il comporte d'une part, disposé dans la chaussure au droit l'emplacement destiné à être occupé par la voute plantaire, un coussin monté mobile, relié à un moyen de transmission de mouvement, lui-même lié à un actionneur disposé dans le talon ladite chaussure, ledit actionneur et ledit moyen de transmission étant conçus aptes à transformer l'appui résultant de la pose dudit talon au sol, en un déplacement dudit coussin pour appliquer une pression brève contre la pompe veineuse plantaire.
  • Selon l'invention, l'ensemble comprenant l'actionneur et le moyen de transmission est conçu apte à mobiliser le coussin pendant une instant très bref afin que ledit coussin applique une pression brève contre la pompe veineuse plantaire, et à cet effet il comporte des moyens de débrayage du mouvement, actifs au-delà d'une valeur prédéfinie de course du déplacement.
  • Tous les dispositifs de stimulation de la pompe veineuse qui existent à ce jour présentent l'inconvénient d'un maintien de la pression, alors qu'il est nécessaire pour être efficace que la pression soit brève, ce que permet le dispositif selon l'invention.
  • Selon une caractéristique additionnelle du dispositif selon l'invention, l'actionneur comporte un élément mobile verticalement dans le talon, dont une extrémité déborde, directement ou indirectement, de la face d'appui dudit talon, tandis que l'autre extrémité coopère avec le moyen de transmission qui consiste en un levier présentant des qualités de ressort.
  • Selon un autre mode de réalisation du dispositif selon l'invention, l'actionneur comporte un élément mobile verticalement dans le talon de la chaussure, dont une extrémité déborde, directement ou indirectement, à l'intérieur de ladite chaussure, tandis que l'autre extrémité coopère, au travers de moyens de renvoi, avec le moyen de transmission qui consiste en un levier.
  • Selon un autre mode de réalisation du dispositif selon l'invention, l'actionneur comporte un élément mobile verticalement dans le talon, tandis que le moyen de transmission est mobile perpendiculairement ou sensiblement perpendiculairement à l'axe de déplacement dudit actionneur.
  • Selon une caractéristique additionnelle du dispositif selon l'invention, le coussin est mû de manière hydraulique ou pneumatique.
  • Selon une autre caractéristique additionnelle du dispositif selon l'invention, le moyen de transmission comprend une pompe qui alimente un vérin qui mobilise le coussin, et qui est actionnée au travers d'un mécanisme délivrant une impulsion lors de la pose au sol du talon.
  • Ce dispositif selon l'invention vient, en partie, se substituer à la marche sur le plan circulatoire en faisant fonctionner la pompe veineuse plantaire par un simple appui du pied sur le sol, favorisant ainsi la remontée du sang vers le coeur.
  • Ce dispositif incorporé dans la chaussure est simple, autonome, ne nécessite aucun entretien. Il a l'avantage de pouvoir équiper presque tous les modèles de chaussures, classiques ou modernes.
  • Ce dispositif mécanique applique une pression sur la voûte plantaire à l'endroit où se trouve la pompe veineuse. Cette pression est simplement provoquée par l'appui du talon de la chaussure sur le sol. La pompe veineuse plantaire étant ainsi stimulée, la remontée du sang vers le coeur s'effectue, et active la circulation sanguine et de ce fait limite l'apparition de différents problèmes veineux.
  • Ce dispositif est particulièrement destiné à toutes personnes en station debout, marchant ou piétinant, tels les commerçants (coiffeurs, vendeuses derrière leur comptoir), personnel dans les usines devant les machines. Personnel dans la restauration etc.
  • Ce dispositif est également approprié aux personnes sédentaires dans leurs appartements qui ne sortent pas beaucoup, les personnes âgées par exemple.
  • Le faible coût des chaussures équipées du dispositif selon l'invention permettra à un très grand nombre de personnes de pouvoir les acquérir pour leur santé et leur bien-être.
  • Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente plusieurs modes de réalisation non limitatifs.
  • Dans le dessin annexé :
    • la figure 1 représente une vue schématique en élévation de profil d'une chaussure équipée du dispositif selon l'invention.
    • la figure 2 représente une vue schématique en plan du même dispositif selon un autre mode de réalisation.
  • En référence à la figure 1, on peut voir une chaussure 1 équipée d'un dispositif 2 de stimulation de la pompe veineuse plantaire selon l'invention.
  • Ce dispositif 2 comprend un actionneur 3 comprenant un coulisseau 30 apte à coulisser verticalement dans le talon 10 de la chaussure 1, dont une extrémité 31, celle du côté de la face d'appui 11 du talon 10, déborde le plan de cette face d'appui 11, tandis que son autre extrémité 32 vient au contact d'un levier 4 solidarisé, au travers d'un moyen de fixation 40, à l'arrière du talon, tandis que l'extrémité opposée comporte un coussin 41 disposé dans la chaussure 1 au droit de l'emplacement destiné à être occupé par la pompe veineuse plantaire.
  • On comprendra que lors de la pose du talon 10 au sol, l'extrémité 31 du coulisseau 30, qui est recouverte d'une paroi souple de protection 33, est repoussée, que le coulisseau 30 se déplace et que son extrémité 32 vient mobiliser le levier 4 en sorte de transmettre ce déplacement au coussin 41 qui vient en pression contre la pompe veineuse plantaire.
  • Il est toutefois nécessaire que la pression ne soit pas prolongée, aussi l'actionneur 3 est associé à un moyen de débrayage.
  • Ainsi le coulisseau 3 consiste en piston comprenant un corps 34 dans lequel peut coulisser une tige 35, dont la tête consiste en l'extrémité 31.
  • Entre la tête 31 et le corps 34 est intercalée une cale 36 permettant de limiter le coulissement de la tige 35 dans le corps 34, en sorte de permettre la transmission du mouvement au levier 4. Toutefois, la cale 36 est constituée d'au moins deux parties, mobiles en écartement comprenant chacune un doigt conique 37 apte à venir, lors du déplacement du coulisseau 3 au contact d'une paroi déflectrice 38, en sorte de provoquer l'écartement des parties formant la cale 36, et rendre cette dernière inactive. La cale étant retirée, la tige 35 peut pénétrer dans le corps 34, ce qui annule la poussée contre le levier 4. La tige peut ensuite ressortir du corps, repoussée par un ressort ou un fluide comprimé, tandis que la cale 36 se reforme sous l'action d'un élément ressort 39, de type anneau élastique, qui l'entoure.
  • Le dispositif selon l'invention est alors prêt à une autre utilisation.
  • Selon un autre mode de réalisation non représenté, l'actionneur 3 agit sur le coussin 41 au travers de moyens d'articulation formant renvoi d'angle, et qui peuvent transmettre le mouvement.
  • En référence maintenant à la figure 2, on peut voir un dispositif de stimulation de la pompe veineuse plantaire conforme à l'invention, réalisé selon un second mode de réalisation.
  • On notera que ce second mode de réalisation est plus compact que le premier, et surtout moins encombrant dans le sens de la hauteur.
  • Ce dispositif comporte également un coussin 41, disposé dans la chaussure 1 au droit de la pompe veineuse du pied, et mobile en déplacement sous l'action d'un vérin hydraulique 5 lui-même alimenté par une pompe 50 au travers d'une canalisation 51.
  • La pompe 50 est susceptible d'être mise en fonctionnement au travers d'un moyen d'actionnement 6, lequel comporte un premier levier 60 monté pivotant dans un plan parallèle ou sensiblement parallèle à la face d'appui 11 du talon 10, non visible sur cette figure, apte à venir au contact d'un bouton 52 d'actionnement de la pompe 50, un second levier 61 également mobile dans un plan parallèle ou sensiblement parallèle à la face d'appui 11 du talon 10, muni d'une encoche 62 en forme d'arc de cercle, contre le bord 63 de laquelle peut se déplacer, selon une direction perpendiculaire, la partie conique 64 d'un doigt 65 dont une extrémité, disposée du côté de la face d'appui 11 du talon 10, déborde de celle-ci. La partie la plus large de la partie conique 64 est située du côté de son extrémité qui déborde la face d'appui 11, en sorte que lors de la pose du talon 10 au sol, le doigt 65 pénètre dans le talon 10, et sa partie conique repousse le second levier 61 qui pivote.
  • Le second levier 61 est lié au premier 60 par l'intermédiaire d'un bras 66, monté pivotant par une extrémité sur le second levier 61 et rappelé par un ressort 67, tandis que son autre extrémité comporte une encoche 68 qui coopère avec un plot 69 du premier levier 60.
  • En fonctionnement, le second levier 61, déplacé par la partie conique 64 d'un doigt 65, déplace le premier levier 60 contre le bouton 52 d'actionnement de la pompe 50, en étant repoussé par le bras 66. Lorsque le déplacement du second levier 61 atteint un certain angle, le plot 69 échappe de l'encoche 68, et la poussée est stoppée, même si le doigt 65 reste en pression.
