  • Patent number: 11318266
    Abstract: Apparatus and methods provide control for generation of a flow of air to a patient's airways for different respiratory therapies. The pressure and a flow rate may be simultaneously controlled so as to provide a pressure therapy and a flow therapy. The system may include one or more flow generators, in which the control of the pressure and flow rate may include altering the output of one or more of the flow generators and/or an optional adjustable vent. The pressure and flow rate may each be held at a constant. One or both of the pressure and flow rate may also vary in accordance with a desired therapy. The air may be provided via a patient interface that includes a vent to atmosphere, which may be the adjustable vent. The vent may be actuated by a controller to implement the simultaneous control of pressure and flow rate of the air.

  • Publication number: 20210346633
    Abstract: Apparatus permit a delivery of a flow of breathable gas to a patient's airways. In one version, a coupler extension may include a seat portion to permit use of a mask with a nasal cannula. In some versions, the coupler extension is configured to conduct the flow of gas to prongs of a nasal cannula. The seat portion can receive and seal with a cushion of a respiratory mask and may have a sealing bevel to promote sealing between the cushion of the respiratory mask and a facial contact surface of a user. In some versions, a nasal interface may include naris pillows to seal with and conduct a flow of breathable gas into a nares of a user. Each naris pillow may include a nasal projection to conduct a further flow of gas. The nasal projection may extend within the naris beyond the seal of the naris pillow.

  • Publication number: 20210290873
    Abstract: A blower includes a housing including a proximal opening and a distal opening that are co-axially aligned, a stator component provided to the housing, an impeller positioned between the proximal opening of the housing and the stator component, and a motor adapted to drive the impeller. The impeller includes a plurality of impeller blades. The stator component includes a plurality of air directing grooves along its exterior surface. The leading edge of the air directing grooves extend tangentially outwards from the outer tips of the impeller blades and are configured to collect the air exiting the impeller blades and direct it from a generally tangential direction to a generally radial direction by dividing the air from the impeller and directing the air along a curved path towards the distal opening so that airflow becomes substantially laminar.

  • Publication number: 20210008320
    Abstract: A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modeled based on the transformed data set.

  • Publication number: 20200246564
    Abstract: An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.
