Abstract: A vent assembly for use with a respiratory mask of the type used in CPAP treatment includes a porous disk portion that is attached to a biasing member such that the disk portion is maintained in a substantially sealed position against a main vent to minimize airflow through at least one side vent of the vent assembly. Debris build-up on the disk portion can cause the biasing member to deflect to provide an additional path for airflow through the at least one side vent. In another embodiment, the vent assembly can also include an anti-asphyxia feature to provide an airflow path from the environment to the user. An oxygen diverter valve may be disposed between the breathing apparatus flow generator and an oxygen injection port.

Abstract: A tub for a humidifier includes an inner tub configured to hold a supply of water; an outer tub configured to receive the inner tub, the outer tub including a bottom and a cavity being formed between the bottom and the inner tub when the inner tub is received in the inner tub; and a valve configured to control a flow of the supply of water from the inner tub to the cavity. The valve is closed to prevent the flow when the inner tub is received in a first position in the outer tub and open to permit the flow when the inner tub is received in a second position in the outer tub.

Abstract: A method for controlling a humidifier of a CPAP device including a controller, the method including controlling a heating element in the humidifier with command signals from the controller, sensing a temperature of a fluid in the humidifier with a sensor in the humidifier that transmits signals to the controller, establishing an acceptable operating range for the signal transmitted to the controller, determining whether the transmitted signal is within the acceptable operating range, if the signal is within the acceptable operating range treating the signal as being indicative of the temperature of the fluid in the humidifier and using the signal to control the heating element, and if the signal is outside of the acceptable operating range, the controller determines the humidifier to be unavailable.

Abstract: A humidifier includes a base configured to retain a body of liquid therein, a top cover, and a seal disposed between the top cover and the base. At least a portion of the base is constructed of a heat conducting material. The top cover defines both an inlet and an outlet communicated with an interior of the base. The inlet is configured to receive pressurized breathable gas and the outlet is configured to deliver the pressurized breathable gas with added humidity.

Abstract: Methods of an apparatus determine a quantity of a body of water in a humidifier such as by indirect measurement. The quantity of water may be determined by measuring one or more properties or characteristics, from which the quantity of water may be inferred. Characteristics of a flow of air, the humidifier, and/or the body of water may be measured. The characteristics may be, for example, pressure, flow rate, noise, vibration, temperature, electrical or mechanical. These may be measured by one or more sensors, which may be located in the humidifier, RPT device, air circuit or the patient interface. The methods described may have advantages, for example in being able to detect the quantity of water without requiring sensors to be present in a disposable component, and in some cases, without introduction of additional sensors.

Abstract: A CPAP device includes a flow generator comprising a motorized fan with an outlet. The motorized fan is configured to pressurize a supply of gas. The flow generator further comprises a flow generator outlet in communication with and offset from the motorized fan outlet and comprises a connector configured to receive the pressurized supply of gas from the flow generator, the connector being in communication with the flow generator outlet and positioned downstream of the motorized fan outlet. The connector comprises an attaching portion at a first end, the attaching portion configured to be coupled to the flow generator. The connector also comprises a flexible sealing portion at a second end opposite the first end, the flexible sealing portion comprising a bellows-type conforming face seal that is axially and/or laterally flexible. In addition the connector comprises a channel provided between the attaching portion and the flexible sealing portion for delivering the pressurized supply of gas from the first end of the connector to the second end of the connector.
