Abstract

Cet appareil est du type de ceux qui contrôlent si la pression de l'air respiratoire devient inférieure à une valeur prédéterminée pendant l'inspiration et supérieure à une autre valeur prédeterminée pendant l'expiration et, lorsque cela se produit actionnent des organes de signalisation, dans le premier cas après une temporisation. Dans l'appareil selon l'invention, l'aiguille 3 d'un indicateur de pression 2, déviée par la pression qui règne dans le conduit du gaz respiratoire, est guidée à travers une barrière pneumatique 6 à une valeur maximale réglable de surpression et à travers une barrière pneumatique 5 à valeur minimale réglable de dépression, et à chaque barrière est raccordé un circuit logique 12, 4, associé à un élément de temporisation 9 dans le cas de la dépression, qui aboutit à des éléments de signalisation 13, 14, 17.
