  • RESPIRATORY ASSISTANCE APPARATUS
    Publication number: 20240042148
    Abstract: A head-mounted respiratory assistance apparatus configured to provide a respiratory gases stream to a user. The head-mounted respiratory assistance has a main body securable to the head of a user and a blower unit that is operable to generate a pressurised gases stream from a supply of gases from the surrounding atmosphere. A patient interface is provided on the main body that has a gases inlet which is fluidly connected to the blower unit and which is configured to deliver the pressurised gases to the user's nose and/or mouth.

  • HUMIDIFICATION SYSTEM
    Publication number: 20230355914
    Abstract: A humidification system has a humidification source and a main gases flow path. The main gases flow path has a low pressure region and a high pressure region. In some embodiments, each of the low pressure region and the high pressure region has an aperture. The pressure difference between the apertures promotes a gases flow between the main gases flow path and the humidification source, and results in humidifying the gases in the main gases flow path.
