HUMIDIFICATION DEVICE FOR A POSITIVE AIRWAY PRESSURE BREATHING APPARATUS

A respiratory ventilation device-for sending a fan-generated air flow into a duct extending to a respiratory mask-extends between lower (bottom) and upper ends. A ventilation chamber contains the fan and is connected to a humidifier, which has a water-accommodating reservoir and a connecting chamber adjacent the ventilation chamber. An intake opening leads out of the ventilation chamber. An exhaust opening leads into an exhaust channel attachable to the duct. A humidification chamber has the water reservoir. First and second openings are formed between the connecting and humidification chambers. The connecting chamber extends between the humidification and ventilation chambers. A separating wall extends between the connecting and humidification chambers. The first and second openings are made in the separating wall, which is arranged such that the humidification chamber extends between the bottom and the separating wall. The connecting chamber extends between the separating wall and the ventilation chamber.
