A breathing gas humidifier for connection between a respirator and a patient, comprises a float chamber having water therein up to a predetermined level which is connected by a top connection to a mixing chamber above water level and is connected by a bottom connection to the mixing chamber below water level. A heater is in the bottom connection for keeping the water boiling in the mixing chamber. The respiratory gas is circulated through a respiratory gas line which extends through the mixer and has a discharge portion extending out of the mixer which is adapted to be connected through a mouthpiece to the patient. An overheater is provided in the circulating line discharge between the mixing chamber and the mouthpiece, in the direct vicinity of the mixing chamber, which is operated in accordance with the temperature sensed by a temperature sensor at the mouthpiece connection to the patient to a desired final temperature before it is delivered to the patient. |
