Abstract

The invention relates to a micro-vibrator system incorporated into plaster casts in order to prevent the damage caused by a patient, suffering from a broken leg that has been operated on, putting weight on that leg. The patient, through negligence or oversight, puts weight on their injured leg and causes collateral damage, namely causes the internal screwed plate to deform. This invention allows a patient who has been operated on to avoid putting pressure on their operated-on leg, by means of a micro-vibrator alert. The invention relates to a system made up of two parts: • a medical sole made of silicone containing a micro vibrator bonded directly to the (highly sensitive) sole of the foot which will be surrounded with plaster, or attached to the skin of the leg by a hook and loop fastener • a metal soleplate fixed to the outside of the plaster cast and superposed with the internal sole, this soleplate containing two metal push-button switches, one on the front of the foot and one at the rear of the foot. In the event of error, as soon as the front of the foot or the rear of the foot is in contact with the ground, one of the switches activates the micro-vibrator and the patient will then stop putting load through the floor in order to avoid inexorable damage.

Description

Système de micro-vibreur intégré aux plâtres Micro-vibrator system integrated into the casts
Domaine de l’invention Field of invention
La présente invention appartient au domaine des dispositifs médicaux utilisés dans le cas d’une fracture simple ou complexe nécessitant l’usage du plâtre en plus d’éviter toute pression appliquée sur le pied. The present invention belongs to the field of medical devices used in the case of a simple or complex fracture requiring the use of plaster in addition to avoiding any pressure applied to the foot.
Problème technique Technical problem
Les patients subissant une opération nécessitant la pose du plâtre sur l’un des pieds sont généralement sensés rester immobile et éviter de produire la moindre pression sur le pied au risque de subir des conséquences grave sur le pied touché. Patients undergoing an operation requiring the placement of a cast on one of the feet are generally supposed to remain still and avoid producing the slightest pressure on the foot at the risk of suffering serious consequences on the affected foot.
Malgré toutes les précautions, certains patients se trouve par simple oubli en situation grave à cause d’une ré fracturation provoqué par un choque inconscient sur le pied en rétablissement. Ce qui provoque, éventuellement, une autre intervention chirurgicale. Despite all the precautions, some patients simply forget to find themselves in a serious situation because of a fracture caused by an unconscious shock on the recovering foot. Which eventually leads to another surgery.
Abrégé de l’invention Abstract of the invention
Fréquemment, lorsqu’un patient souffre d’une cassure osseuse et traité avec la plaque vissée interne et le plâtre. Le patient, par oubli ou négligence, appuie sur la jambe malade et provoque des dégâts collatéraux à savoir la déformation de la plaque vissée interne. Cette invention permet au patient opéré d’éviter d’appuyer sur sa jambe traitée moyennant une alerte via un micro-vibreur. Frequently, when a patient suffers from a broken bone and treated with the internal screw plate and plaster. The patient, by forgetfulness or negligence, presses on the sick leg and causes collateral damage, namely the deformation of the internal screwed plate. This invention allows the operated patient to avoid pressing on his treated leg by means of an alert via a micro-vibrator.
L’invention concerne un système composé de deux parties : The invention relates to a system composed of two parts:
• Une semelle médicale au silicone contenant un micro-vibreur collée directement sur la plante du pied (partie très sensible) qui sera entourée du plâtre, ou attaché à la jambe par un scratch sur la peau. • A medical silicone insole containing a micro-vibrator glued directly to the sole of the foot (very sensitive part) which will be surrounded by plaster, or attached to the leg by a scratch on the skin.
• Une semelle métallique fixée à l’extérieur du plâtre et superposée à la semelle interne, cette semelle contient deux interrupteurs poussoir métalliques ; un sur l’avant-pied et l’autre sur l’arrière-pied. • A metal sole attached to the outside of the plaster and superimposed on the internal sole, this sole contains two metal push-button switches; one on the forefoot and the other on the rearfoot.
Si par erreur, dès que l’avant-pied ou l’arrière -pied est en contact avec le sol, l’un des interrupteurs active le micro-vibreur et par suite le patient stoppera l’effort sur le sol pour éviter des dommages inexorables. If by mistake, as soon as the forefoot or the hindfoot is in contact with the ground, one of the switches activates the micro-vibrator and consequently the patient will stop the effort on the ground to avoid damage inexorable.
Description technique : Technical description :
9 fois sur 10 le plâtre est employé pour soigner des fractures, il sert à immobiliser le membre pendant que l’os guérit naturellement et spontanément, en effet, l’os est formé d’un tissu qui se répare lentement, grâce au plâtre, les fragments de l’os sont maintenus afin qu’ils se resoudent dans la bonne position. 9 times out of 10 the plaster is used to treat fractures, it is used to immobilize the limb while the bone heals naturally and spontaneously, in fact, the bone is made up of a tissue that is slowly repaired, thanks to the plaster, the fragments of the bone are held so that they rejoin in the correct position.
Pour configurer cette position, on installe des vis provisoires, ensuite, on enfile un jersey, pour éviter que le plâtre ne touche la peau, au-dessus, on place un rembourrage au coton recouvert d’un papier crêpé pour le rendre plus homogène. Et enfin, on déroule les bandelettes de plâtre humides autour du membre, sinon on utilise des résines synthétiques qui sont plus solides en plus d’avoir la faculté d’être plus légères et imperméables. To configure this position, we install temporary screws, then we put on a jersey, to prevent the plaster from touching the skin, above, we place a cotton padding covered with a crepe paper to make it more homogeneous. And finally, we unroll the wet plaster strips around the limb, otherwise we use synthetic resins which are stronger in addition to having the ability to be lighter and waterproof.
Premier mode de réalisation : First embodiment:
La première semelle contenant le micro-vibreur sera en crêpe vu que ce matériau est d’ores et déjà utilisé pour le placement du plâtre. The first sole containing the micro-vibrator will be in crepe since this material is already used for the placement of the cast.
Nous pouvons donc remarquer à travers le graphique ci-dessous que la résistance du matériau est importante, ce qui nous permet de nous sentir en sécurité quant à la suspension d’un micro-vibreur sur le matériau. So we can notice through the graph below that the resistance of the material is important, which makes us feel safe about suspending a micro vibrator on the material.
La deuxième semelle vu qu’elle sera à l’extérieur devra être plus résistante, on prendra donc une semelle métallique (matériau léger comme aluminium). The second sole since it will be outside will have to be more resistant, so we will take a metal sole (light material like aluminum).
L’ajout que nous établirons quant au placement du plâtre sera donc la première semelle qu’on va placer au niveau de la voûte plantaire du patient juste après avoir placé le papier crêpé, cette semelle faite de crêpe qu’on peut trouver commercialisée contiendra le micro-vibreur fixé grâce à un tube adhésif, deux fils reliant le micro-vibreur à la batterie seront suspendus à l’extérieur de la surface dédiée au plâtre de telle sorte à ce qu’ils soient à l’extérieur du plâtre lorsque celui-ci est placé.The addition that we will establish regarding the placement of the plaster will therefore be the first sole that we will place at the level of the patient's arch of the foot just after having placed the crepe paper, this sole made of crepe that can be found on the market will contain the micro-vibrator fixed with an adhesive tube, two wires connecting the micro-vibrator to the battery will be suspended outside the surface dedicated to the plaster in such a way that they are outside the plaster when the latter is this is placed.
Après le placement du plâtre, on va devoir fixer la deuxième semelle grâce à des vis sur le plâtre, sur cette semelle on aura au préalable fixé deux boutons poussoirs (figure 3) sur le bas de la semelle, ces boutons poussoirs devront être connectés aux deux fils liés à la batterie qui est liée au microvibreur. Avec cette configuration dès que le patient posera son pied sur le sol, le sol exercera une force d’appui sur les boutons poussoirs, qui vont générer un signal au micro-vibreur, qui par la suite va vibrer et donc alerter le patient de sa condition pour lui éviter d’autres dommages. After the placement of the plaster, we will have to fix the second sole with screws on the plaster, on this sole we will have previously fixed two push buttons (figure 3) on the bottom of the sole, these push buttons must be connected to the two wires linked to the battery which is linked to the microvibrator. With this configuration, as soon as the patient places his foot on the ground, the ground will exert a pressing force on the push buttons, which will generate a signal to the micro-vibrator, which will then vibrate and therefore alert the patient of his condition to prevent him from further damage.
Ensuite, après le placement du plâtre, on va devoir fixer la deuxième semelle grâce à des vis sur le plâtre, sur cette semelle on aura au préalable fixé deux boutons poussoirs sur le bas de la semelle, ces boutons poussoirs devront être connectés aux deux fils liés à la batterie qui est elle-même liée au micro-vibreur. Then, after placing the plaster, we will have to fix the second sole with screws on the plaster, on this sole we will have previously fixed two push buttons on the bottom of the sole, these push buttons must be connected to the two wires linked to the battery which is itself linked to the micro-vibrator.
Avec cette configuration dès que le patient posera son pied sur le sol, les boutons poussoirs vont automatiquement envoyer un signal au micro-vibreur qui va vibrer et donc alerter le patient de sa condition lui évitant ainsi d’autres dommages. With this configuration as soon as the patient puts his foot on the ground, the push buttons will automatically send a signal to the micro-vibrator which will vibrate and therefore alert the patient of his condition, thus avoiding further damage.
Deuxième mode de réalisation : Second embodiment:
Selon le deuxième mode de réalisation le poussoir touché par le sol envois un signal au microvibreur attaché à la jambe de l’utilisateur. L’attachement est fait par un scratch détachable. According to the second embodiment, the pusher touched by the ground sends a signal to the microvibrator attached to the user's leg. The attachment is made by a detachable scratch.
Quant au micro-vibreur, il serait judicieux de choisir une intensité pas assez élevée, vu qu’il fixé, sur la jambe pour alerter le patient mais certainement pas au point d’endommager son membre fracturé, une sollicitation allant jusqu’à 0.5 m/s2 est considérée saine pour un humain normal, les vibrations reçues dans le corps lors d’un trajet routier ont une accélération de 0.3 m/s2. Nous pouvons donc nous baser sur la même accélération pour notre micro-vibreur. Description des dessins :As for the micro-vibrator, it would be wise to choose an intensity that is not high enough, since it is fixed on the leg to alert the patient but certainly not to the point of damaging his fractured limb, a stress of up to 0.5 m /s 2 is considered healthy for a normal human, the vibrations received in the body during a road trip have an acceleration of 0.3 m/s 2 . We can therefore base ourselves on the same acceleration for our micro-vibrator. Description of the drawings:
