Abstract

L'invention concerne un ouvre-bouche (100) et un dispositif médical qui appartiennent au domaine technique des appareils médicaux. L'ouvre-bouche (100) comprend un corps (10), et une première partie de compression (20) et une seconde partie de compression (30) qui sont disposées sur des côtés opposés du corps (10). Un trou traversant (11) est ménagé dans le corps (10), avec une entrée (13) et une sortie (14) qui sont formées sur les deux côtés du trou traversant (11) respectivement. La première partie de compression (20) présente une première face de compression (21), et la seconde partie de compression (30) présente une seconde face de compression (31). La première face de compression (21) est conçue pour venir en appui contre un côté extérieur des dents supérieures (200) ou contre la lèvre supérieure (600), et la seconde face de compression (31) est conçue pour venir en appui contre un côté extérieur des dents inférieures (300) ou contre la lèvre inférieure (700). Vue dans une direction de l'entrée (13) à la sortie (14), la première face de compression (21) est plus proche de la sortie (14) que ne l'est la seconde face de compression (31), de sorte que la mâchoire supérieure et la mâchoire inférieure (1001) sont décalées l'une de l'autre. La mâchoire supérieure et la mâchoire inférieure (1001) sont amenées à être décalées l'une de l'autre de sorte que, pendant tout le processus d'examen endoscopique, une action est exercée sur un tissu pharyngé d'un patient au moyen de la première face de compression (21) et de la seconde face de compression (31), afin de maintenir les voies respiratoires supérieures du patient dans un état dégagé.
