The invention relates to a breathing assistance apparatus that may be configured to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks within the apparatus or impacts to the apparatus. In other forms, the apparatus may be configured to allow for easy assembly and/or safe operation.

Respiratory device

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.

Breathing assistance apparatus

A breathing assistance apparatus that comprises a housing with inner and outer walls and an upper surface, wherein the walls and upper surface are integrally formed as a single part to avoid seams or joins between the walls to reduce the risk of damage to electronics within the apparatus as a result of liquid leaks.
