Description

1 DISPOSITIF ELECTRONIQUE DE MESURE D'ANGLES, VITESSES ET ACCELERATIONS POUR PATIENT ATTEINT D'UNE DEFICIENCE SUR LES MEMBRES INFERIEURS Description de l'invention 1.1 Domaine technique de l'invention : La présente invention concerne un dispositif électronique de mesure, dans les 3 axes en position statique et dynamique, des angles, vitesses et accélérations des membres inferieurs d'un patient atteint d'une déficience motrice.ELECTRONIC DEVICE FOR MEASURING ANGLES, SPEEDS AND ACCELERATIONS FOR A PATIENT WITH DEFICIENCY ON LOWER LIMBS Description of the invention 1.1 Technical field of the invention: The present invention relates to an electronic measuring device, in the 3 axes in a static and dynamic position, angles, speeds and accelerations of the lower limbs of a patient with a motor impairment.

Ce dispositif est composé : - d'un boitier léger et compact qui se fixe sur la prothèse ou le membre déficient du patient. - un logiciel sur ordinateur portable ou tablette. Ce dispositif est particulièrement adapté aux patient amputés d'un membre inférieur et porteur d'une prothèse ostéo intégrée. Il embarque un logiciel qui analyse à fréquence élevée les valeurs des angles, vitesses et accélérations. Il permet la mesure en continue du niveau d'activité du patient et donc le calcul de la fatigue mécanique de I 'aboutement et de la vis. Ces deux pièces sont critiques et sont les plus fragiles de la prothèse ostéo intégrée. Ce dispositif permet d'anticiper la casse de l'aboutement et de la vis. il permet donc de prévoir le changement de ces deux pièces mécaniques au plus juste dans le temps. _ Ce dispositif est aussi adapté à tout patient atteint d'une déficience mécanique des membres inferieurs : il permet, par une analyse fine des angles, vitesses et accélérations, 3036477 2 de mettre en évidence les pathologies existantes. Ce dispositif peut aussi servir à l'évaluation des bénéfices d'une période de rééducation fonctionnelle d'un patient. Il permet de mesurer dans le temps les progrès accomplis par le patient dans sa phase de rééducation et réapprentissage de la marche. 5 1.2 Etat de la technique antérieure : Pour mesurer les amplitudes maximum des membres, un personnel soignant se sert d'un goniomètre. Cet outil n'est utilisable qu'en position statique. Par ailleurs, sa précision est faible et la restitution des données n'est pas fiable. Les tapis de marche permettent d'analyser la marche du patient et de fournir des données 10 en mode dynamique. Cependant ces équipements sont extrêmement lourds à déplacer. Ils ne permettent pas d'extraire des données d'angles, vitesses et accélérations. Le goniomètre et le tapis de marche ne sont pas utilisables sur une durée longue et sans interruption dans le temps (plusieurs mois). Ils ne peuvent pas être fixés sur la prothèse du patient ou sur le membre déficient. 15 Enfin, ces deux appareils ne permettent pas de calculer la fatigue de l'aboutement et de la vis d'un appareillage ostéo intégré du membre inferieur. 3036477 3 1.3 Exposé de l'invention Ce dispositif est constitué des composants suivants : - un boitier en matière composite - un micro contrôleur logé dans le boitier en matière composite 5 - un logiciel embarqué dans le micro contrôleur et développé en langage assembleur - un ou plusieurs gyromètres logés dans le boitier en matière composite - un ou plusieurs accéléromètres logés dans le boitier en matière composite - une ou plusieurs batteries logées dans le boitier en matière composite - un lecteur de carte mémoire logé dans le boitier en matière composite 10 - un module wifi logé dans le boitier en matière composite - une prise USB logée dans le boitier en matière composite - un écran LCD / OLED logé dans le boitier en matière composite - un logiciel développé sur ordinateur portable ou tablette Le boitier électronique est suffisamment miniaturisé et léger pour être fixé sur la prothèse 15 d'un patient pour une durée de plusieurs mois voire pendant toute la durée de vie de la prothèse (plusieurs années). Le micro contrôleur est programmé d'une telle façon qu'il permet de mesurer, calculer et analyser en temps réel et à fréquence élevée les angles, vitesses angulaires et accélérations d'un membre inferieur pendant la phase de marche du patient. La carte 20 mémoire stocke ces données. Ce dispositif compte le nombre de pas effectués par le patient et permet de mesurer son niveau d'activité. Des compteurs sont crées en mémoire du micro contrôleurs et/ou sur carte mémoire amovible pour stocker le nombres de pas, les angles, vitesses et accélérations à chaque pas effectué par le patient.This device is composed of: - a lightweight and compact box that attaches to the patient's prosthesis or deficient limb. - software on a laptop or tablet. This device is particularly suitable for patients with lower limb amputation and wearing an integrated osteo-prosthesis. It embeds software that analyzes at high frequency the values of angles, speeds and accelerations. It allows the continuous measurement of the activity level of the patient and thus the calculation of the mechanical fatigue of the abutment and the screw. These two pieces are critical and are the most fragile of the integrated osteo prosthesis. This device makes it possible to anticipate the breakage of the abutment and the screw. it allows to predict the change of these two mechanical parts at the fairest in time. This device is also adapted to any patient suffering from a mechanical deficiency of the lower limbs: it makes it possible, by a fine analysis of the angles, speeds and accelerations, to highlight the existing pathologies. This device can also be used to evaluate the benefits of a period of functional rehabilitation of a patient. It makes it possible to measure over time the progress made by the patient in his phase of reeducation and relearning of walking. 1.2 State of the Prior Art: To measure maximum limb magnitudes, a caregiver uses a goniometer. This tool can only be used in static position. Moreover, its accuracy is low and the restitution of the data is not reliable. Walking mats are used to analyze the patient's walk and provide data in dynamic mode. However these equipments are extremely heavy to move. They do not make it possible to extract data from angles, speeds and accelerations. The goniometer and the treadmill can not be used for a long time and without interruption in time (several months). They can not be attached to the patient's prosthesis or the deficient limb. Finally, these two devices do not make it possible to calculate the fatigue of the abutment and the screw of an integrated osteo apparatus of the lower limb. 1.3 Description of the Invention This device consists of the following components: a case made of composite material a microcontroller housed in the case of composite material; software embedded in the microcontroller and developed in assembler language; several gyrometers housed in the composite material housing - one or more accelerometers housed in the composite material housing - one or more batteries housed in the composite material housing - a memory card reader housed in the composite material housing 10 - a module wifi housed in the composite housing - a USB socket housed in the composite housing - an LCD / OLED in the housing made of composite material - software developed on a laptop or tablet The electronic box is sufficiently miniaturized and lightweight for to be fixed on the prosthesis 15 of a patient for a period of several months or even over the entire life of the prosthesis (several years). The microcontroller is programmed in such a way as to measure, calculate and analyze in real time and at high frequency the angles, angular velocities and accelerations of a lower limb during the patient's walking phase. The memory card stores this data. This device counts the number of steps taken by the patient and makes it possible to measure his level of activity. Counters are created in memory of the microcontrollers and / or removable memory card to store the number of steps, angles, speeds and accelerations at each step performed by the patient.

La fatigue mécanique de l'aboutement et de la vis est calculée par une fonction qui prend comme arguments les angles, vitesses et accélérations fournis par les gyroscopes et 3036477 4 accéléromètres. Les valeurs de fatigue mécanique calculées par le dispositif sont comparées aux valeurs de test de fatigue fournis par le fabriquant de l'aboutement et de la vis. Le résultat de cette comparaison est stocké en mémoire du micro contrôleur et/ou sur carte mémoire amovible.The mechanical fatigue of the abutment and the screw is calculated by a function that takes as arguments the angles, speeds and accelerations provided by the gyroscopes and 3036477 4 accelerometers. The mechanical fatigue values calculated by the device are compared to the fatigue test values provided by the manufacturer of the abutment and the screw. The result of this comparison is stored in memory of the microcontroller and / or removable memory card.

5 Le résultat de la comparaison est restitué par le clignotement d'une LED visible de l'extérieur du boitier et ou sur l'écran LCD / OLED du dispositif : le patient ou prothésiste est informé qu'un changement d'aboutement et vis doit être effectué. Un logiciel est développé sur ordinateur portable ou tablette pour l'affichage et l'analyse des données fournies par le boitier électronique. Il est une aide au diagnostique médical 10 car il contient des modèles de courbes correspondantes aux diverses pathologies existantes. Ce dispositif permet d'anticiper la casse de l'aboutement et de la vis. Il permet donc de planifier le changement de ces deux pièces au plus juste dans le temps. 1.4 Mode de réalisation 15 Le boitier est en matière composite. Il encapsule tous les composants électroniques. Il présente une fente pour insérer et retirer la carte mémoire. L'écran LCD/OLED est intégré sur la face haute du boitier. Le boitier est suffisamment robuste pour résister aux chocs et protéger l'électronique embarquée.5 The result of the comparison is restored by the flashing of an LED visible from outside the box and or on the LCD / OLED screen of the device: the patient or prosthetist is informed that a change of abutment and screw must to be done. Software is developed on a laptop or tablet for displaying and analyzing the data provided by the electronic box. It is an aid to medical diagnosis because it contains models of curves corresponding to the various existing pathologies. This device makes it possible to anticipate the breakage of the abutment and the screw. It allows to plan the change of these two parts at the fairest in time. 1.4 Embodiment 15 The housing is made of a composite material. It encapsulates all electronic components. It has a slot for inserting and removing the memory card. The LCD / OLED screen is integrated on the upper face of the case. The case is rugged enough to withstand shock and protect embedded electronics.

20 L'ensemble est alimenté par une ou plusieurs batteries lithium. 3036477 5 1.5 Application industrielle : Ce dispositif est particulièrement adapté aux patients porteurs de prothèse osteo intégrée de membre inférieur. Il permet une mesure précise de la fatigue mécanique de l'aboutement et de la vis pour planifier un changement au plus juste dans le temps.The assembly is powered by one or more lithium batteries. 1.5 Industrial application: This device is particularly suitable for patients with integrated lower limb osteo prosthesis. It allows a precise measurement of the mechanical fatigue of the abutment and the screw to plan a change at the most just in time.

5 Les bénéfices pour le patient sont : - moins de casse intempestive de l'aboutement et de la vis et donc moins d'anesthésies générales et moins de risques d'infection - une simplification de l'opération chirurgicale du changement de l'aboutement et de la vis car ils sont changés avant déformation plastique ou casse.The benefits for the patient are: - less accidental breakage of the abutment and the screw and therefore less general anesthesia and less risk of infection - a simplification of the surgical operation of the change of the abutment and screw as they are changed before plastic deformation or breakage.

10 Ce dispositif est aussi adapté à tout patient atteint d'une déficience des membres inferieurs. Il est un outil d'aide au diagnostique des pathologies : l'analyse des courbes d'angles, vitesses et accélérations permettent de détecter des anomalies. Ce dispositif est aussi un outil d'aide à l'évaluation des bénéfices d'une période de rééducation fonctionnelle. Par un usage continu, il permet d'évaluer les progrès accomplis 15 par le patient. Enfin son encombrement inférieur à celui des dispositifs existants rende ce système plus accessible à tous les personnels soignants.This device is also suitable for any patient with a lower limb deficiency. It is a tool for diagnosing pathologies: the analysis of angle curves, speeds and accelerations make it possible to detect anomalies. This device is also a tool to help evaluate the benefits of a period of functional rehabilitation. Through continuous use, it makes it possible to evaluate the progress made by the patient. Finally, its smaller footprint than existing devices makes this system more accessible to all caregivers.
