Abstract
A device for humidifying respiratory gases is provided. The device includes: an all-polymer humidification chamber; a heating element positioned independently and proximate to the humidification chamber; a base unit supporting the humidification chamber; a computer that sends adjustment instructions to a water filling valve coupled with the humidification chamber; a plurality of sensors determining light within the humidification chamber and coupled with the base unit; an airflow conduit coupled with the humidification chamber; a heater wire within the airflow conduit; and an insulation material with grooves thereon surrounding the heater wire. The adjustment instructions instruct the water filling valve to self-adjust to meet a predetermined water level objective. The airflow conduit delivers gas to the patient. The heater wire heats the gas being delivered. The grooves on the insulation wire wick water within the humidification chamber away to re-evaporation regions.
