Abstract

L'invention concerne un dispositif de voies aériennes oropharyngé qui fixe avec précision les voies respiratoires d'un patient. Le dispositif de voies aériennes oropharyngé de la présente invention comprend : un corps de passage; une tente gonflable; et une conduite d'injection d'air. Le corps de passage comprend : une extrémité proximale disposée à l'extérieur de la bouche; une pointe insérée dans la bouche; une partie droite s'étendant à partir de l'extrémité proximale; et une partie incurvée s'étendant de la partie droite vers la pointe. Une ouverture inclinée est formée de la pointe à la limite entre la partie droite et la partie incurvée sur la surface incurvée de la partie incurvée disposée adjacente à la langue. La tente gonflable est fixée au corps de passage de façon à recouvrir l'ouverture inclinée, et est gonflée par une injection d'air pour pousser la langue vers l'avant. La conduite d'injection d'air est reliée à la tente gonflable pour l'injection d'air. Selon la présente invention, la tente gonflable, lorsqu'elle est contractée, est gonflée par l'injection d'air et pousse la langue de façon à fixer avec précision les voies respiratoires. En outre, étant donné que la langue est amenée en contact avec la tente contractée au moment de l'insertion, il est facile d'insérer le corps de passage, et les voies respiratoires sont empêchées d'être fermées par le corps de passage, ce qui permet d'améliorer la fiabilité et la sécurité.
