Abstract

L'invention apporte un humidificateur avec un passage de gaz de faible volume (de l'ordre de 50 ml). Il comprend un élément chauffant 50 dans une enveloppe 30 contenant de l'eau et possédant une paroi microporeuse 40 qui est commune à l'espace contenant l'eau à l'intérieur de l'enveloppe et à l'espace traversé par les gaz. La paroi microporeuse 40 est perméable à la vapeur d'eau, mais imperméable à l'eau à l'état de liquide. L'enveloppe est renforcée par un support 10 qui dirige également l'écoulement des gaz sur la surface de l'enveloppe 30. L'élément chauffant 50 est un élément plat avec un enroulement en spirale pour éviter l'effet de bulles de gaz ou de vapeur d'eau sur les performances de l'élément chauffant. Utilisable notamment en combinaison avec un respirateur à proximité immédiate d'un patient.
