Abstract

Titre de l’invention Dispositif de délivrance de NO avec système de dosage d’urgence L’invention concerne un dispositif de délivrance de NO (1) pour fournir un gaz contenant du NO comprenant une ligne d’injection de NO (111), un dispositif de mesure de débit (112) et un dispositif à vanne (113). Le dispositif à vanne (113) est normalement fermé. Une ligne de secours (201) raccordée à la ligne d’injection (111) comprend une électrovanne de secours (202) normalement ouverte et un dispositif de contrôle de débit (210). Des moyens de pilotage (130) pilotent ces éléments. En cas de dysfonctionnement des moyens de pilotage (130), l’électrovanne de secours (202) passe en position ouverte, alors que le dispositif à vanne (113) passe en position fermée. Le dispositif de contrôle de débit (210) fournit le gaz à un débit gazeux de secours préfixé, déterminé à partir des mesures de débit du gaz fournies par le dispositif de mesure de débit (112), pendant le fonctionnement normal du dispositif (1), avant le dysfonctionnement. Installation de fourniture de gaz comprenant un tel dispositif de délivrance de NO (1) et un ventilateur médical (2). Figure de l’abrégé : Fig. 1
