Abstract
A respiratory humidification device includes: a casing; a separator wall to divide an interior space into filling and humidification chambers, wherein a bottom edge of the separator wall leaves a space between it and the casing bottom to define a passage allowing water to flow atop the casing bottom between the chambers, and enabling the water level to rise enough to block the passage to prevent respiratory gas from passing therethrough; a valve and float within the filling chamber to control water flow into the filling chamber to prevent the water level from rising higher than a threshold; and wherein an outer wall of the casing and the separator wall cooperate with the water surface within the humidification chamber to define an elongate tube-like pathway through which respiratory gas proceeds along a path extending generally parallel to the water surface within the humidification chamber to be humidified.
