Abstract

See full text

A PAP device is configured to deliver a pressurized flow of respiratory gas to a patient's airways and includes a flow generator with a blower configured to pressurize the flow of respiratory gas. A flexible face seal is positioned at an outlet end of a blower discharge path. A tub configured to hold a body of water and humidify the pressurized flow of respiratory gas includes a heat conducting base plate and a side wall. A base supports both the flow generator and the tub and includes a floor with a heater plate and a spring biased catch configured to secure the tub to the base. The spring biased catch is configured so that applying a downward force on the tub so that the tub presses against the floor of the base secures the tub to the base and allows the tub to be released from the base.
