  • Patent number: 12268818
    Abstract: A blower unit for use as part of an integrated blower/humidification system is described. The blower unit has an outer casing, which encloses and forms part of the blower unit, the casing including an air inlet vent. The blower unit further includes a humidifier compartment for receiving a humidifier unit with a separate gases inlet and outlet, the compartment having a heater base for heating the contents of the humidifier unit. The compartment also has a blower inlet port which aligns with the humidifier unit inlet in use, the blower providing a gases path through the casing between the inlet vent and the inlet port. The blower unit also includes a fan for providing a pressurised gases stream along the gases path, and a power supply unit for powering the fan. The gases path is routed over the power supply unit in order to provide a cooling air flow.

  • Patent number: 12201777
    Abstract: A humidifier heater base assembly has a heater plate with a thermally conductive portion and a perimeter portion around a perimeter of the heater plate. A resilient member has an inner part attached to the perimeter portion and an outer part adapted to provide a resilient perimeter flange around at least part and preferably the whole of the perimeter portion. The resilient member fixes the heater base to the humidifier by the resilient perimeter flange such that the heater plate and the inner part can move relative to the humidifier in a direction substantially transverse to the general plane of the heater plate. At least a portion of the resilient perimeter flange remains stationary relative to the humidifier.

  • Publication number: 20220203062
    Abstract: A device for use as part of a breathing assistance system for providing gases to a user. The device may include a fan, an enclosure for receiving a humidification chamber or both. A user interface of the device can indicate the operating mode of the device, whether a peripheral device is connected and whether a gases conduit is correctly connected to the outlet of the device. A controller in the device may hide or block options from the display of the user interface and may also initiate a power save mode when the device is powered by a battery.
