Abstract

Système d'auscultation sans fil utilisant un stéthoscope numérique multifonctions, en version améliorée en termes de commodité d'usage et de qualité de produit. Des données d'auscultation d'un patient recueillies par le stéthoscope électronique numérique sont transmises sans fil et, puis, émises par un haut-parleur séparé ou un casque d'écoute via un récepteur sans fil voisin, ainsi le fil de communication supplémentaire provenant du stéthoscope est superflu. Le stéthoscope peut être utilisé librement et un docteur tout autant qu'un patient peuvent écouter ensemble les sons de l'auscultation diagnostiquée, de manière à fournir un service médical plus détaillé. En outre, diverses fonctions peuvent être incorporées au stéthoscope au moyen d'un détecteur thermique de mode sans contact ou d'une lampe. Le système de la présente invention est conçu pour comprendre le stéthoscope numérique (10) à unité de transmission sans fil incorporée, utilisant la technologie blue-tooth, transmettre les données d'auscultation recueillies sans fil via le stéthoscope (10), disposer d'un dispositif de réception des données d'auscultation transmises sans fil depuis le stéthoscope (10) et, puis, les écouter au moyen d'un haut-parleur (30) ou d'un casque d'écoute (40) relié sélectivement au dispositif de réception (20).
