Description

La présente invention concerne un dispositif de détection d'un mouvementThe present invention relates to a device for detecting a movement

corporel en prévention lombaire. Les dispositifs médicaux actuels destinés à prévenir le mal de dos sont nombreux mais leur mode d'action est statique et de l'ordre de la contention. C'est le cas des ceintures lombaires, lombostats et autres corsets utilisés efficacement en cas de fractures, d'inflammation et de pathologie mécanique de la colonne. Mais si leur efficacité est grande en cas d'hyperpression articulaire postérieure avec arthrose, lyse isthmique ou spondylolysthésis, ils ont, sauf le corset lombaire qui solidarise la colonne lombaire avec une cuisse, peu d'efficacité en cas de problème discal car ils ne limitent que très peu les risques d'hyperpression antérieure provoqués lors d'un mouvement de flexion, c'est-à-dire en se penchant en avant. Par ailleurs si en pédagogie thérapeutique, en consultation médicale ou dans les écoles du dos, il est demandé aux patients de privilégier la flexion dans les hanches, dos droit, la réalisation pratique de cette manoeuvre n'est pas d'accès facile pour beaucoup. Il manque donc un dispositif simple destiné à avertir l'utilisateur d'un mouvement de flexion au niveau de sa colonne lombo sacrée, c'est-à-dire le bas du dos, dans le cadre de la prévention des hernies discales ou de leurs récidives Le dispositif, selon l'invention, permet de remédier à ce manque. Il est constitué en effet, selon une première caractéristique, d'une pochette plate et souple collée à la peau de l'utilisateur en haut de la colonne lombaire qui permet de contenir un petit dispositif sonore plat à pile, dont la languette interrupteur est reliée par une ficelle et un élastique à une pastille également collée à la peau, juste en dessous de la colonne lombaire, le fil élastique déjà sous légère tension de telle sorte dès que l'éloignement des 2 éléments collés, provoqué par la flexion lombaire aura dépassé lune certaine limité, la languette de l'interrupteur sera tirée et déclenchera le son d'avertissement. Selon des modes particuliers de réalisation - la modification de longueur de la ficelle, par un simple noeud ou un passage dans une boucle à fente permet le règlage du déclenchement de l'alarme. - un test préalable permet de diminuer par exemple la longueur de la ficelle si l'alarme se déclenche trop vite, et inversement. -2- - l'union par une ficelle et un élastique de la languette de l'interrupteur d'un détecteur sonore adhérent à la peau à une pastille située à distance permet le déclenchement du dispositif sonore quand les deux éléments s'éloignent, ce qui est la cas au niveau de la colonne lombaire en passant du dos droit au dos rond - le dispositif d'alarme peut déclencher un simple bruit d'alarme ou même un message sonore, voire un message sonore qui préviendra de plusieurs degrés de tension, faible, moyen fort qui correspond à l'augmentation de la flexion de la colonne lombo sacrée. - les deux éléments plats, à savoir la pochette contenant le dispositif d'alarme et la pastille peuvent être réalisés en tissus, en matière plastique ou en toute autre matière souple agréable et non nocive pour la peau et peuvent adhérer à la peau grâce à un film adhésif, un spray de colle spéciale ou tout autre moyen non blessant. - l'utilisation de ce dispositif à d'autres endroits du corps permet d'autres exercices de préventions - des adaptations telles que : pour le contrôle de la flexion cervicale au niveau du cou, une casquette ou un bandeau qui permet d'éviter les cheveux, ou encore, pour le contrôle de la région abdominale, une ceinture circulaire au niveau du sternum et un sanglage de type string inextensible pour une fixation en regard du pubis, permet de contourner les problèmes de collage dans cette région. - la fixation du dispositif sonore sur un support autre que la pochette le contenant peut faciliter le changement de pile. - l'élastique peut être relié à 2 morceaux de ficelle dont un a une longueur fixe et l'autre une longueur réglable. Les dessins annexés illustrent l'invention : La figure 1 représente le dispositif de l'invention, de face. La figure 2 représente le dispositif de l'invention, de profil, dans une de ses utilisations pratiques, ici pour le contrôle de la flexion lombaire. La figure 3 représente le dispositif de l'invention, de profil, dans une de ses utilisations pratiques, ici pour le contrôle de la flexion cervicale. La figure 4 représente le dispositif de l'invention, de profil, dans une de ses utilisations pratiques, ici pour le contrôle de la contraction abdominale. En référence à ces dessins, le dispositif est constitué d'un petit dispositif sonore plat (1) à pile plate (2) contenu dans une pochette plate (3) de quelques centimètres de dimension dont l'interrupteur (4) est relié par une ficelle (5) qui inclut un élément élastique (6) à l'anneau auto bloquant (7) d'une pastille (8) de quelques centimètres. Lorsque les deux élément plats sont collés au niveau de la zone à contrôler, c'est à dire l'un en haut en regard de la jonction dorsolombaire de la colonne (8), l'autre en bas en regard du sacrum (9), et une fois le réglage de la tension effectué, par adaptation de la longueur de la ficelle ou écartement adéquat des deux pièces, l'alarme sonore se déclenchera dès que l'éloignement des 2 éléments collés, provoqué par la flexion lombosacrée (10) aura dépassé la limite fixée par le thérapeute ou l'accompagnateur. L'effet global du dispositif consiste à déclencher un signal sonore d'alarme lorsque les 2 pièces collées à la peau sont écartées d'une distance qui correspond à la limite du mouvement à ne pas dépasser. L'invention concerne donc un dispositif permettant de faciliter et de garantir l'apprentissage des bons gestes de prévention lombaire et donne à l'examinateur un moyen diagnostic et de contrôle. Le dispositif selon l'invention est particulièrement destiné aux salles de remise en forme et aux cabinets de kinésithérapie, aux Etablissements de réadaptation et aux cabinets de Médecine Physique et Réadaptation, mais aussi au grand public dans le cadre d'exercices à domicile ou de pratiques sportives en association. 30  body in lumbar prevention. Current medical devices intended to prevent back pain are numerous but their mode of action is static and of the order of contention. This is the case of lumbar belts, lombostats and other corsets used effectively in case of fractures, inflammation and mechanical pathology of the column. But if their effectiveness is high in cases of posterior articular hyperpressure with osteoarthritis, isthmic lysis or spondylolysthesis, they have, except the lumbar corset which solidarises the lumbar spine with a thigh, little effectiveness in case of disc problem because they do not limit that very little the risks of anterior hyperpressure caused during a bending movement, that is to say by leaning forward. Moreover, if in therapeutic pedagogy, in medical consultation or in the schools of the back, it is asked the patients to privilege the bending in the hips, back right, the practical realization of this maneuver is not of easy access for many. Therefore, a simple device is needed to warn the user of a flexion movement at the level of his lumbar sacral column, ie the lower back, as part of the prevention of herniated discs or their recurrences The device according to the invention makes it possible to remedy this deficiency. It is constituted in fact, according to a first feature, a flat and flexible pouch glued to the skin of the user at the top of the lumbar spine that can contain a small flat sound device battery, whose switch tab is connected by a string and an elastic to a pellet also stuck to the skin, just below the lumbar spine, the elastic thread already under slight tension so that as soon as the distance of the 2 glued elements, caused by the lumbar flexion has exceeded some limited moonlight, the switch tab will be pulled and will sound the warning sound. According to particular embodiments - the modification of length of the string, by a simple node or a passage in a slit loop allows trimming of the triggering of the alarm. - A preliminary test can reduce for example the length of the string if the alarm is triggered too quickly, and vice versa. -2- - the union by a string and an elastic of the tongue of the switch of a sound detector adhering to the skin at a remotely located pellet allows the triggering of the sound device when the two elements move away, this which is the case in the lumbar spine passing from the right back to the round back - the alarm device can trigger a simple alarm sound or even a sound message, or even a sound message that will prevent several degrees of tension, weak, medium strong which corresponds to the increase of the flexion of the lumbar sacral column. the two flat elements, namely the pouch containing the alarm device and the tablet may be made of fabric, plastic or any other soft material that is pleasant and non-harmful to the skin and may adhere to the skin thanks to a adhesive film, a special glue spray or any other non-injurious means. - The use of this device in other parts of the body allows other prevention exercises - adaptations such as: for the control of cervical flexion in the neck, a cap or a headband that avoids hair, or, for the control of the abdominal region, a circular belt at the sternum and an inextensible string-like strapping for fixation opposite the pubis, allows to circumvent the gluing problems in this region. - Fixing the sound device on a support other than the pouch containing it can facilitate the change of battery. - The elastic can be connected to 2 pieces of string, one of which has a fixed length and the other an adjustable length. The accompanying drawings illustrate the invention: FIG. 1 represents the device of the invention, from the front. Figure 2 shows the device of the invention, in profile, in one of its practical uses, here for the control of lumbar flexion. Figure 3 shows the device of the invention, in profile, in one of its practical uses, here for the control of cervical flexion. Figure 4 shows the device of the invention, in profile, in one of its practical uses, here for the control of abdominal contraction. With reference to these drawings, the device consists of a small flat sound device (1) with flat battery (2) contained in a flat pocket (3) of a few centimeters in size, the switch (4) is connected by a twine (5) which includes an elastic element (6) to the self-locking ring (7) of a pellet (8) of a few centimeters. When the two flat elements are glued at the area to be controlled, that is to say one at the top opposite the dorsolumbar junction of the column (8), the other at the bottom facing the sacrum (9) , and once the adjustment of the tension carried out, by adaptation of the length of the string or adequate spacing of the two parts, the audible alarm will be triggered as soon as the removal of the 2 glued elements, caused by the lumbosacral flexion (10) will have exceeded the limit set by the therapist or accompanist. The overall effect of the device is to trigger an alarm sound signal when the two pieces stuck to the skin are spaced a distance that corresponds to the limit of movement not to exceed. The invention therefore relates to a device for facilitating and guaranteeing the learning of good lumbar prevention and gives the examiner a means of diagnosis and control. The device according to the invention is particularly intended for fitness rooms and physiotherapy cabinets, rehabilitation establishments and practices of Physical Medicine and Rehabilitation, but also for the general public in the context of home exercises or practices sports association. 30
