  • Publication number: 20230338694
    Abstract: The present invention provides a method and apparatus for reducing condensation in a respiratory circuit during a delivery of humidifying agent into the respiratory circuit. A first amount of humidification agent to a first volume of gas is delivered to a patient respiratory circuit during a patient inhalation cycle or immediately after a patient exhalation cycle, and the humidification agent or the first volume of gas is heated. Condensation is removed from the respiratory circuit at least in part by providing, during a patient exhalation cycle or immediately after a patient inhalation cycle, a second amount of the humidification agent to a second volume of gas being delivered from the gas source to the patient respiratory circuit, the second amount of the humidification agent being significantly less than the first amount of the humidification agent.

  • Patent number: 10646683
    Abstract: The present invention provides a method for reducing condensed humidifying agent in a humidification system by pulsing a delivery of humidifying agent into a respiratory circuit. During a non-pulsed interval, gas flowing through the respiratory circuit will evaporate the condensed humidifying agent present in the respiratory circuit. The present invention also provides a method and apparatus for delivering humidified gas to a patient, wherein the delivery avoids the problems associated with a stationary water humidifier. In the method, the delivery of humidifying agent is precisely controlled to deliver a flow of humidifying agent to a volume of gas.

  • Patent number: 9067036
    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.
