Abstract

L’invention concerne une unité de décomposition (1) de protoxyde d’azote (N2O) comprenant un conduit principal de gaz (100) pour convoyer un gaz contenant du N2O expiré par un patient, une pompe (120) comprenant une entrée de gaz (120a) et une sortie de gaz (120b), l’entrée de gaz (120a) de la pompe (120) étant en communication fluidique avec le conduit principal de gaz (100), un réacteur catalytique (130) en communication fluidique avec la sortie de gaz (120b) de la pompe (120), et un premier capteur de débit (101) agencé dans le conduit principal de gaz (100). Elle comprend par ailleurs un réservoir de gaz (103) à volume variable en communication fluidique avec le conduit principal de gaz (100) entre le premier capteur de débit (101) et la pompe (120), et un deuxième capteur de débit (104) agencé dans le conduit principal de gaz (100) entre le réservoir (103) et la pompe (120). Installation de fourniture d’un mélange gazeux N2O/O2 comprenant une source de gaz (3) de protoxyde d’azote (N2O), un circuit patient (23), un réservoir de gaz (24), une interface respiratoire (21) et une unité de décomposition (1) du N2O selon l'invention.
