Abstract

Un dispositif mélangeur de gaz pour appareils d'assistance respiratoire doit être perfectionné de telle sorte qu'il puisse être utilisé aussi bien en fonctionnement stationnaire que mobile. Le dispositif mélangeur de gaz selon l'invention présente un récipient de stockage (5) dans lequel de l'air sous pression et de l'oxygène peuvent être introduits au moyen de soupapes de dosage (3, 8). En outre, un ventilateur (10) est branché sur le récipient de stockage (5) et aspire de l'air provenant du milieu ambiant (11). Afin de doser le gaz qui provient des sources de gaz sous pression (4, 6) au moyen des soupapes de dosage (3, 8), un premier niveau de pression de service est réglé à l'intérieur du récipient de stockage (5). Lorsqu'il y a commutation pour passer à un fonctionnement avec le ventilateur, le niveau de pression de service est abaissé à un niveau de pression qui est adapté à la pression maximale d'assistance respiratoire.
