Abstract

L'invention se rapporte à un dispositif permettant de capturer de manière non retenue et inconsciente un signal biologique provenant d'un patient évoluant dans un environnement quotidien afin de l'analyser, et de diagnostiquer le patient pour suivre l'évolution de son état de santé et de sa convalescence après une maladie. Des morceaux d'une feuille de cuivre plaquée à l'argent, et dont les surfaces arrières sont revêtues d'un adhésif, sont appliqués sur une surface d'un siège (1) de type tabouret style western, au niveau de parties ombrées (2a,2b,2c), illustrées, pour créer dans celui-ci une conductivité. Ces morceaux servent à constituer des électrodes différentielles et une électrode indifférenciée pour capter des signaux électrocardiographiques, et après avoir été correctement amplifiés, ces signaux sont analysés et évalués par un procédé d'évaluation analytique selon ou similaire à une première induction parmi douze inductions normales.
