An air delivery conduit for conveying breathable gas from a positive airway pressure device to a patient interface includes a tubular wall structure constructed from a textile material. A reinforcing structure may be provided to the wall structure that is structured to prevent kinking or collapsing of the wall structure. The wall structure may include a warp having a plurality of lengthwise textile warp threads arranged in a circle and a weft having a textile weft thread that is woven through the warp threads.

A humidification canister for humidifying a breathing gas, the humidification canister includes a fluid supply configured to supply a fluid and a first gas flow path in fluid communication with the fluid supply. A first gas flow path is configured to humidify the breathing gas with the fluid. A second gas flow path at least partially surrounds the first gas flow path. A method of insulating a breathing gas in a humidification canister using a gas is also disclosed.

An atomizer for an inhaler includes a housing, a gasket, a liquid absorbing sheet, a wick, and an atomizing element. The housing includes a first housing and a second housing, the first housing and the second housing form a liquid reservoir therebetween for storing liquid. The gasket is sleeved on the first housing, the gasket defines a liquid conducting hole in communication with the liquid reservoir. The liquid absorbing sheet is sleeved on the first housing in contact with the gasket, the liquid absorbing sheet is configured to absorb the liquid in the liquid reservoir via the liquid conducting hole. The wick is in contact with the liquid absorbing sheet and configured to draw the liquid from the liquid absorbing sheet. The atomizing element is fixed to the wick and configured to atomize the liquid in the wick.

A delivery device for and a method of delivering gases to the nasal airway, in particular therapeutic gases and gases in combination with active substances, either as powders or liquids, for enhanced uptake of the active substances.

A method and device are used for administering a humidified aerosol to a patient interface by providing and guiding a first gas flow having a humidified aerosol, a second gas flow having humidified respiratory gases, and a liquid flow of a thermally balancing liquid, thermally balancing the first and second gas flow by parallel guiding the first and second gas flow such that the first and second gas flow are guided in a manner that they are at least partially surrounded by the liquid flow of the thermally balancing liquid, mixing the first and second gas flow to obtain enriched respiratory gases having the humidified aerosol, and administering the enriched respiratory gases to the patient interface. The method and the device avoid the administration of dry or re-dried powdered aerosols and unwanted accumulation of and blockage by powdered material. The device is useful in respiratory support of preterm infants.

A disposable nasal air moisturizing device is removably attached to a nasal cannula to release a moisturizing liquid into a breathing gas and a patient's nasal airway. The intranasal sponges and moisturizing liquid prevents and treats both abrasions from the nasal cannula and excessive drying of the mucosa. This reduces the incidence of nosebleeds in patients using supplemental nasal oxygen.

Embodiments of an adaptor for delivering diffused aromatic agents to a user of a CPAP machine is disclosed in this document. The adaptor may include a connector body, a diffuser pad disposed within the connector body, and at least one coupling mechanism on the connector body coupling the connector body within the air supply and positioning the diffuser pad within the airflow of a CPAP machine. The adaptor may be configured to couple directly to a CPAP mask. Similarly, the adaptor may be configured to be placed in the airflow between the CPAP air generator and the mask. The adaptor may be configured such that no modification of the existing CPAP hose, machine, or mask is required.

A breathing support system is provided. The system may include a breathing support device configured to deliver gas to a patient and a display device associated with the breathing support device. The display device may be configured to display a work of breathing graphic indicating one or more work of breathing measures regarding the patient's breathing.

A breathing gas humidifier capsule having an evaporator module with a heated, hydrophobic liquid water reservoir defined by water vapor-permeable walls. Liquid water in the hydrophobic reservoir is vaporized by a heater and the generated water vapor is entrained in a passing breathing gas stream.

Systems and methods are disclosed for delivering medication to a patient. One such system has an aerosol generator for aerosolizing medication. The generator is located outside the airway of a patient. A chamber is provided for receiving aerosolized medication from the generator. The system has a carrier gas supply tube for delivering carrier gas to the chamber, and an aerosol delivery tube for receiving the aerosolized medication and the carrier gas from the chamber. The aerosol delivery tube delivers the aerosolized medication to the patient. A distal end of the aerosol delivery tube is positioned inside the airway of the patient in order to discharge the aerosolized medication within the patient's airway.
