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.

Humidification system

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.

A nebulizer is provided that includes an internal medication chamber and a pressurized gas diverter. The internal medication chamber is configured for holding a medication. The pressurized gas diverter includes a diverter orifice.

Breath actuated nebulizer having a pressurized gas diverter with a diverter orifice

A device for humidifying respiratory gases. The device includes: a humidification component that holds a water volume; and a heating element that converts received electrical energy to electromagnetic radiation, wherein the electromagnetic radiation is transferred to the water volume, thereby heating the water volume to achieve a heated water volume.

Humidifying respiratory gases

A heater wire including at least one extending component disposed thereon. The heater wire is positioned within a respiratory gas conduit. The heater wire may include a wire component and a groove that extends along a length of the heater wire. The heater wire may also include threads extending from an outer surface of the heater wire that faces away from the wire component. The threads may be woven or braided threads.

Capillary heater wire

A heater wire for removing condensation from a respiratory gas conduit is provided. The heater wire includes at least one groove disposed thereon. The heater wire is positioned in a respiratory gas conduit. The groove may wick up water from a condensation region within the respiratory gas conduit and transport the wicked up water from the condensation region to a re-evaporation region. The wicked up water may be evaporated by a hot surface of the wire.

Fluted heater wire

A system for providing humidification to gas to be provided to a patient to support breathing including: a humidification component configured for adding water vapor to the gas; and a humidification component controller coupled with the humidification component and configured for receiving humidification target value information, the humidification component controller including: a humidification target value determiner configured for determining, based on received humidification target value information, a humidification target value of at least two possible humidification target values, the humidification target value identifying a humidification level setting corresponding to the patient.

Humidifying gas for respiratory therapy

A respiratory component coupled with a breathing circuit, the respiratory component including at least one groove disposed upon a surface of the respiratory component, wherein the respiratory component is not a heater wire.

Transporting liquid in a respiratory component

A heater wire including at least one extending component disposed thereon. The heater wire is positioned within a respiratory gas conduit.

A device for maintaining a water level in a respiratory humidification system, said device comprising: at least one sensor positioned external to a humidification component, the at least one sensor configured for sensing water related information in the humidification component and providing the water related information to a water control module, the water related information comprising data configured for being used to control an operation of the water control module.

Maintaining a water level in a humidification component

A heater wire for removing condensation from a respiratory gas conduit. The heater wire includes at least one groove disposed thereon. The heater wire is positioned in a respiratory gas conduit.

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.
