摘要：
An apparatus for use in humidifying a flow of treatment gas for a user includes: a housing； an inlet structured to receive the flow of treatment gas from a gas flow generator； an outlet structured to convey the flow of treatment gas to a patient interface device； a compartment defined in the housing, the compartment being structured to hold a volume of water therein； a primary valve disposed between the inlet and the compartment, the primary valve being structured to permit passage of the flow of treatment gas from the inlet to the compartment and to prevent passage of a fluid from the compartment to the inlet； and a secondary valve disposed between the compartment and the inlet which is structured to permit passage of a fluid from the compartment to the inlet and to prevent passage of the flow of treatment gas from the inlet to the compartment.
