Description
L’invention concerne un procédé et un dispositif pour la mesure de paramètres physiologiques d’un individu par contact temporaire avec une surface réceptrice. Le terme temporaire entend caractériser un dispositif non portable, à la différence de dispositifs de l’art antérieur tels que des bracelets, ceintures pectorales, lunettes, boîtiers de ceinture, casques etc. dits «wearables» en anglais.The invention relates to a method and a device for measuring physiological parameters of an individual by temporary contact with a receiving surface. The term temporary is intended to characterize a device that is not portable, unlike devices of the prior art such as bracelets, chest straps, glasses, belt cases, helmets, etc. called “ wearables ” in English.
La mesure de paramètres physiologiques tels que la fréquence, cardiaque, la fréquence respiratoire, la tension artérielle et leurs évolutions temporelles, permet de détecter, voire d’anticiper et de prévenir, des situations à risque pour un individu, allant de risques relativement bénins tel que le stress jusqu’à des risques gaves tels que des accidents cardiovasculaires.The measurement of physiological parameters such as heart rate, respiratory rate, blood pressure and their changes over time, makes it possible to detect, or even anticipate and prevent, risk situations for an individual, ranging from relatively benign risks such as that stress up gaves risks such as cardiovascular accidents.
Plus particulièrement la pandémie de COVID 19 conduit à l’isolement des personnes dans le cadre de mesures de confinement visant à réduire la circulation du virus, et notamment en ce qui concerne les personnes âgées.More particularly, the COVID 19 pandemic leads to the isolation of people as part of containment measures aimed at reducing the circulation of the virus, and in particular with regard to the elderly.
Les contraintes résultant de ces mesures, et notamment associées au phénomène de réchauffement climatique et à l’augmentation de la fréquence des canicules estivales, mettent en danger les personnes isolées et plus particulièrement les personnes âgées ayant par ailleurs des problèmes cardiovasculaires, pulmonaires ou métaboliques, lesquelles ont encore plus difficilement accès à des endroits climatisés.The constraints resulting from these measures, and in particular associated with the phenomenon of global warming and the increase in the frequency of summer heat waves, endanger isolated people and more particularly the elderly who also have cardiovascular, pulmonary or metabolic problems, which have even more difficulty in accessing air-conditioned places.
La téléassistance apporte un début de solution à ces situations. Ainsi, la mesure de paramètres physiologiques tels que la température corporelle, le rythme cardiaque, la tension artérielle et la fréquence respiratoire de la personne concernée est associée à la mesure de paramètres environnementaux tels que la température et l’humidité, et transmises à un centre de télésurveillance dans lequel des opérateurs, associés ou non à un système d’analyse d’intelligence artificielle, évaluent la situation.Remote assistance provides the beginning of a solution to these situations. Thus, the measurement of physiological parameters such as body temperature, heart rate, blood pressure and respiratory rate of the person concerned is associated with the measurement of environmental parameters such as temperature and humidity, and transmitted to a center remote monitoring in which operators, associated or not with an artificial intelligence analysis system, assess the situation.
Si une situation potentiellement à risque est détectée, un protocole d’intervention est déclenché, comprenant par exemple l’appel de la personne pour s’assurer que tout va bien et la conseiller le cas échéant sur une conduite à tenir.If a potentially risky situation is detected, an intervention protocol is triggered, including, for example, calling the person to make sure that everything is fine and advising them, if necessary, on what to do.
Le document Alex Buoite Stella et al. «Heat risk exacerbation potential f o r neurology patients during the COVID-19 pandemic and related isolation» International Journal of Biometrology (2021) 65 :627-630 – 8 Novembre 2020, décrit un tel dispositif de téléassistance.The document Alex Buoite Stella et al. “ Heat risk exacerbation potential f o r neurology patients during the COVID-19 pandemic and related isolation ” International Journal of Biometrology (2021) 65:627-630 – November 8, 2020, describes such a remote assistance device.
La difficulté de ces dispositifs de téléassistance est la collecte des informations physiologiques.The difficulty of these remote assistance devices is the collection of physiological information.
Des dispositifs portables, fréquemment désignés par le terme anglosaxon de «wearable», tels qu’un bracelet ou une ceinture pectorale permettent de mesurer de tels paramètres relatifs à l’état physico-psychique de la personne qui les porte.Portable devices, frequently referred to by the Anglo-Saxon term “ wearable ”, such as a bracelet or a chest strap, make it possible to measure such parameters relating to the physical-psychological state of the person wearing them.
En milieu médicalisé, différents types de capteurs peuvent être installés sur un patient afin d’effectuer une surveillance de paramètres physiologiques par l’intermédiaire d’un électrocardiogramme (ECG), d’un électroencéphalogramme (EEG), d’une surveillance respiratoire ou encore de la tension artérielle.In a medical environment, different types of sensors can be installed on a patient in order to monitor physiological parameters by means of an electrocardiogram (ECG), an electroencephalogram (EEG), respiratory monitoring or even blood pressure.
Ces solutions sont toutefois peu adaptées à une collecte régulière et à long terme, par la gêne qu’elles produisent dans les activités quotidiennes et le sentiment de surveillance qu’elles éveillent du fait de leur simple présence.However, these solutions are not well suited to regular and long-term collection, due to the discomfort they cause in daily activities and the feeling of surveillance they arouse due to their mere presence.
En effet, la plupart des paramètres d’intérêt nécessitent pour leur mesure des capteurs en contact avec la peau de l’individu et sont eux-mêmes sensibles à des paramètres environnementaux tels que la température ou l’humidité.Indeed, most of the parameters of interest require for their measurement sensors in contact with the skin of the individual and are themselves sensitive to environmental parameters such as temperature or humidity.
Le document US 10,292,658 décrit un dispositif intégré à un siège de toilettes et comprenant des capteurs entrant en contact avec la peau d’un utilisateur afin de mesurer des paramètres physiologiques, et notamment un électrocardiogramme (ECG).Document US 10,292,658 describes a device integrated into a toilet seat and comprising sensors coming into contact with the skin of a user in order to measure physiological parameters, and in particular an electrocardiogram (ECG).
Outre le fait de devoir être en contact avec la peau, l’acquisition de l’électrocardiogramme d’une personne, ainsi que des paramètres qui peuvent en être déduits, est très sensible l’humidité à la fois ambiante et au niveau du contact avec les électrodes, notamment en présence de sueur, de sorte que cette technique, fiable en laboratoire, est délicate de mise en œuvre dans un capteur autonome, et plus particulièrement si ce dernier n’est pas unwearable.In addition to having to be in contact with the skin, the acquisition of a person's electrocardiogram, as well as the parameters that can be deduced from it, is very sensitive to humidity, both ambient and at the level of contact with the electrodes, in particular in the presence of sweat, so that this technique, reliable in the laboratory, is difficult to implement in an autonomous sensor, and more particularly if the latter is not a wearable .
L’invention vise à résoudre les inconvénients de l’art antérieur et vise à cette fin un dispositif pour l’évaluation des paramètres physiologiques d’un individu en contact fugace avec ledit dispositif, lequel dispositif comprend :
- un capteur de pression comprenant un corps d’épreuve souple et des jauges élémentaires de forte sensibilité sensibles à la déformation dudit corps d’épreuve ;
- une surface réceptrice apte à entrer en contact avec l’individu et à transmettre les efforts résultant de ce contact au capteur de pression ;
- de moyens informatiques, aptes à traiter les signaux issus du capteur de pression et un programme mettant en œuvre lesdits moyens informatiques de sorte à déterminer au moins une information parmi :
- la fréquence respiratoire de l’individus
- la fréquence cardiaque de l’individu
- les évolution de ces fréquences en fonction du temps
et à générer une alerte en fonction de ces résultatsThe invention aims to solve the drawbacks of the prior art and aims to this end at a device for evaluating the physiological parameters of an individual in fleeting contact with said device, which device comprises:
- a pressure sensor comprising a flexible test body and elementary gauges of high sensitivity sensitive to the deformation of said test body;
- A receiving surface able to come into contact with the individual and to transmit the forces resulting from this contact to the pressure sensor;
- computer means, able to process the signals from the pressure sensor and a program implementing said computer means so as to determine at least one item of information from:
- the respiratory rate of the individual
- the individual's heart rate
- the evolution of these frequencies as a function of time
and generate an alert based on these results
Un contact fugace s’entends d’un temps de contact inférieur à 120 secondes, étant entendu que le dispositif objet de l’invention est apte à évaluer les paramètres visées sur des durées bien plus longues.A fleeting contact means a contact time of less than 120 seconds, it being understood that the device which is the subject of the invention is capable of evaluating the parameters referred to over much longer periods.
L’invention est mise en œuvre selon les modes de réalisation préférés mais nullement limitatifs exposés ci-après en référence aux figures 1 à 9, dans lesquels :The invention is implemented according to the preferred but in no way limiting embodiments set out below with reference to Figures 1 to 9, in which:
