Abstract

L’invention se rapporte à un mélangeur (100) d’un respirateur artificiel (1) destiné à assurer le mélange d’un flux d’air et d’un flux d’oxygène. Selon l’invention, le mélangeur comprend une paroi latérale fermée (101) comportant une première ouverture (102) destinée à assurer l’arrivée du flux d’air, une deuxième ouverture (107) destinée à assurer l’arrivée du flux d’oxygène et une troisième ouverture (103) destinée à assurer la sortie du mélange gazeux air/oxygène, ladite paroi (101) s’étendant entre la première ouverture (102) et la troisième ouverture (103), la paroi (101) possédant une rampe (120) interne destinée à dévier le flux d’oxygène pour le placer dans le même sens que le flux d’air au sein du mélangeur (100). Figure pour l’abrégé : Fig. 4The invention relates to a mixer (100) of an artificial respirator (1) intended to ensure the mixing of an air flow and an oxygen flow. According to the invention, the mixer comprises a closed side wall (101) comprising a first opening (102) intended to ensure the arrival of the flow of air, a second opening (107) intended to ensure the arrival of the flow of oxygen and a third opening (103) intended to ensure the outlet of the gaseous air/oxygen mixture, said wall (101) extending between the first opening (102) and the third opening (103), the wall (101) having a internal ramp (120) intended to deviate the flow of oxygen to place it in the same direction as the flow of air within the mixer (100).
