Abstract

La présente divulgation concerne un dispositif qui empêche les pathogènes expulsés dans l'haleine d'entrer à nouveau dans le patient afin de réduire le taux de réplication virale. La divulgation concerne un dispositif comprenant : une première et une seconde soupape unidirectionnelle ; au moins un premier et un second canal d'air ; un embout buccal ; et au moins un premier adaptateur nasal ; la première soupape unidirectionnelle étant fixée au, et en communication fluidique avec le, premier canal d'air ; l'embout buccal étant fixé au, et en communication fluidique avec le, premier canal d'air distal par rapport à la première soupape unidirectionnelle ; la seconde soupape unidirectionnelle étant en communication fluidique avec au moins un second canal d'air ; et le premier adaptateur nasal étant fixé au second canal d'air à une position distale par rapport à la seconde soupape unidirectionnelle. Le second canal d'air comprend une extrémité bifurquée coiffée du premier adaptateur nasal et un second adaptateur nasal.
