Abstract

L'invention concerne un système pour intuber un patient qui présente simultanément les images obtenues par un laryngoscope et par une bougie ou unintroducteur endotrachéal, qui comprend: un laryngoscope qui est composé d'un manche localisé dans sa partie supérieure et une pale ou lame localisée dans la partie inférieure, où ledit laryngoscope capture l'image obtenue par une première microcaméra localisée sous la pale ou lame, cette première microcaméra étant connectée au moyen d'un câble USB intérieur à un circuit imprimé où est disposé un microprocesseur/transmetteur localisé dans le manche qui traite l'image et la transmet au moyen d'un transmetteur de signal sans fil émetteur; une bougie qui est composée d'un corps tubulaire élargi ou d'un guide souple qui comprend dans une extrémité d'insertion ou une extrémité distale une deuxième microcaméra et dans une extrémité proximale un boîtier ou une anse, cette deuxième microcaméra qui capture l'image étant en communication avec un port de sortie; et un dispositif mobile qui possède un récepteur de signal sans fil récepteur et un port d'entrée; ce dispositif moile recevant le signal d'image du laryngoscope à travers ledit récepteur de signal sans fil récepteur et ledit dispositif mobile reçoit le signal d'image de la bougie à travers le port d'entrée; l'écran du dispositif mobile étant divisé en deux moitiés; une première moitié pour déplier l'image transmise par le laryngoscope et une seconde moitié pour déplier l'image transmise par la bougie; et un procédé associé.
