  • Publication number: 20200086073
    Abstract: A reservoir configured to retain a volume of liquid for use in an apparatus for humidifying a flow of pressurised air comprises a base portion and a lid portion. The reservoir may be configured to improve its level of thermal contact to the heater plate using the flow of pressurised air. The reservoir may be configured to improve thermal contact between the reservoir and the heater plate by pre-compression upon engagement of the reservoir with the humidifier. The reservoir may comprise a removable intermediate portion, which may include the inlet tube and/or the outlet tube, for improved access for cleaning. The reservoir may also be configured to prevent overfilling. Overfill prevention features in the reservoir may include defined flow egress paths and/or formation of air locks.

  • Patent number: 10578118
    Abstract: A respiratory apparatus for treating a patient with a respiratory disorder includes a blower configured to generate a supply of pressurized breathable gas. The blower includes a gas inlet and a gas outlet. The gas outlet is configured to deliver the generated supply of pressurized breathable gas to an outlet of the respiratory apparatus for delivery to the patient. The blower also includes an impeller configured to rotate to generate the supply of pressurized gas. The impeller has a single shroud with a plurality of blades extending from a surface of the shroud in an upstream direction relative to the direction of flow of the pressurized breathable gas. Each of the plurality of blades radiate outwards from a hub in the shroud. The hub is configured to receive a motor shaft. In addition, the outer diameter of the shroud varies between maximum portions with a maximum outer diameter and minimum portions with a minimum outer diameter.
