1. A breathing assistance system, comprising:

  • a gas delivery system configured to generate a gas flow;

    a fluid source located downstream from the gas delivery system;

    a gas flow conduit system for communicating the gas flow between the gas delivery system and the fluid source, the gas flow conduit system including an exhaust opening; and

    a flow regulation device associated with the gas flow conduit system, the flow regulation device physically moveable between;

    an operational position that allows the gas flow generated by the gas delivery system to flow downstream past the flow regulation device via the gas flow conduit system; and

    a protection position that prevents gasses and liquids flowing upstream through the gas flow conduit system from reaching the gas delivery system, and directs such gasses and liquids flowing upstream through the exhaust opening in the gas flow conduit system;

    wherein the flow regulation device automatically moves between the operational position and the protection position based at least on the gas flow generated by the gas delivery system.
