  • Publication number: 20230060994
    Abstract: Disclosed are apparatus, systems and devices for providing modular connectivity to a respiratory therapy device. Certain forms relate to an apparatus for supplying a flow of breathable gas at positive pressure for respiratory therapy comprising a pressure generator in a housing, at least one electrical connector to connect to a connectivity module, and a cavity for receiving the connectivity module. Different forms of connectivity module may be provided. This allows for flexibility of connectivity in a respiratory device while allowing for simple installation and removal of the connectivity module.
