Title
(EN) A SMART WRISTBAND FOR MULTIPARAMETER PHYSIOLOGICAL MONITORING
(FR) BRACELET INTELLIGENT PERMETTANT UNE SURVEILLANCE PHYSIOLOGIQUE À PARAMÈTRES MULTIPLES
Abstract
(EN) An ergonomically designed smart wristband for clinical-grade multiparameter monitoring is disclosed. The smart wristband incorporates multiple sensors including custom-designed reflective arterial pulse sensors, a thermopile sensor, and electrocardiogram (ECG) electrodes. When the smart wristband is worn on the wrist, the biosensors contact the skin. The smart wristband may tether wirelessly to a mobile or any other computing device to continuously acquire and stream information like arterial pulse waveform and temperature data. Algorithms running on the computing device or onboard microprocessor analyze the acquired data to report parameters like blood pressure, body temperature, respiration, and blood oxygen. The device can also operate in a fully-standalone mode to accomplish continuous multiparameter physiological monitoring, analysis, and reporting. Whenever the user touches an electrode on the device with a finger of the other hand, an ECG signal is additionally acquired for monitoring parameters such as heart rate and heart rate variability.
(FR) L'invention concerne un bracelet intelligent conçu de manière ergonomique permettant une surveillance de paramètres multiples de qualité clinique. Le bracelet intelligent comprend de multiples capteurs comprenant des capteurs d'impulsion artérielle réfléchissants conçus sur mesure, un capteur à thermopile et des électrodes d'électrocardiogramme (ECG). Lorsque le bracelet intelligent est porté sur le poignet, les biocapteurs entrent en contact avec la peau. Le bracelet intelligent peut s'attacher sans fil à un mobile ou à tout autre dispositif informatique pour acquérir et transmettre en continu des informations telles que des données de forme d'onde d'impulsion artérielle et de température. Des algorithmes exécutés sur le dispositif informatique ou le microprocesseur embarqué analysent les données acquises pour rapporter des paramètres tels que la pression artérielle, la température corporelle, la respiration et l'oxygène sanguin. Le dispositif peut également fonctionner dans un mode entièrement autonome pour réaliser une surveillance physiologique multiparamétrique continue, une analyse et un rapport. Chaque fois que l'utilisateur touche une électrode sur le dispositif avec un doigt de l'autre main, un signal ECG est en outre acquis pour surveiller des paramètres tels que la fréquence cardiaque et la variabilité de la fréquence cardiaque.
