Abstract
A positive pressure gas supply system configured to supply positive pressure gas to a patient includes a CPAP unit configured to generate a flow of positive pressure gas. A humidifier base is positioned to receive the flow of positive pressure gas from the CPAP unit. A receiving portion of the humidifier base is configured to removably receive a refilling module. The refilling module is configured to hold a volume of water, complete a gas flow path partially defined by the humidifier base, and humidify the positive pressure gas. In addition, a respiration tube connecting portion is positioned to remain in communication with a gas discharge passage of the humidifier base when the refilling module is removed from the humidifier base. The respiration tube connecting portion is configured to be connected to a respiration tube and deliver the humidified positive pressure gas to the respiration tube.
