Abstract
A disposable active humidifier particularly for inspiratory lines of respiratory circuits for intensive care, comprising a body (2,2') provided with an inlet (3,3') and an outlet (4,4') for its connection along the inspiratory line and internally forming a chamber (10) for the flow of the gases of the inspiratory line, the humidifier further comprising a hydrophobic membrane (11) forming at least one portion of the surface of the chamber. The body (2,2') can be introduced by immersion in a water containment chamber (21) at least at the region affected by the membrane (11), the membrane being adapted to allow the passage of water in molecular form in the gas flow chamber (10).
