Abstract

Dispositif permettant l'auscultation du coeur fatal à l'aide d'un stéthoscope électronique. Il comprend le cornet acoustique conventionnel sur lequel est appliqué un système comprenant un microphone d'entrée, un amplificateur électronique, et un microphone de sortie; le microphone de sortie transmet les vibrations pneumatiques amplifiées aux tympans par un tube en Y muni d'une lyre; l'amplificateur est alimenté par une pile accessible de l'extérieur et mis sous tension par un contact dont le bouton est situé dans un évidement afin de ne pas obtenir de mises sous tensions intempestives lorsque le praticien transporte un tel système dans sa sacoche. L'invention peut être utilisée dans les applications médicales ayant trait à l'écoute du coeur foetal.
