A humidifier having a humidification chamber for holding water and through which respiratory gas is forced, heated, and humidified and then directed to a patient during respiratory therapy. The humidifier is provided with a cartridge which occupies or displaces a significant or substantial amount of the gas space within the interior cavity, thereby correspondingly reducing the gas volume of the cavity and the compliance of the humidifier. By reducing compliance, the amount of gas which must be compressed, moved, heated and humidified within the humidifier is correspondingly reduced, thereby substantially improving the efficiency and overall functioning of the apparatus. With substantially reduced compliance as provided by the present invention resulting from reduction of between about 20% and about 80% of the volume of the humidifier cavity, a reduction of pressure needed to drive respiratory gas through the humidifier is achieved.
L'invention porte sur un ensemble humidificateur comprenant une cartouche (10) fixée dans la cavité d'une chambre d'humidification de façon à déplacer entre environ 20 % et environ 80 % du volume de la cavité.
