Abstract: 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.

Abstract: A positive airway pressure device includes a blower and a base. A blower outlet passage is connected to the blower and has a central tubular portion and a flexible sealing portion surrounding an outer circumferential surface of the central tubular portion. The base receives a tub with a heat conducting base plate, an internal air passage configured to receive the pressurized flow of respiratory gas from the blower outlet passage, and a pair of tub flanges extending laterally from respective side walls of the tub. Each tub flange has a horizontal portion and a tapered portion. The base further includes a floor with a heater plate a pair of base flanges. Each base flange extends laterally inward from a respective one of the side walls and engages a respective tub flange as the tub is inserted into the base with the tapered portions of the tub flanges being received first.

Abstract: A respirator system includes a respirator with an air filter, a flow generator with a sensorless DC motor, a mask, a processor, a sensor, an electric power source, and a wireless transceiver. The respirator filters air, increase the pressure of the air, delivers the air to the mask at a pressure above ambient, gathers data with the sensor about operation of the respirator, and transmits the data. An intermediate electronic device is separate and remote from the respirator, and is configured to receive the transmitted data process the data, and re-transmit the data. A computer receives the data, processes the data and generates at least one report regarding the respirator or a user of the respirator.
