    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 comprising 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 humidifier for a respiratory apparatus for delivering a humidified flow of breathable gas to a patient includes a humidifier chamber configured to store a supply of water to humidify the flow of breathable gas. The humidifier chamber includes a first heating element configured to heat the supply of water. The humidifier also includes a relative humidity sensor to detect a relative humidity of ambient air and generate signals indicative of the ambient relative humidity; a first temperature sensor to detect a temperature of ambient air and generate signals indicative of the ambient temperature; and a controller configured to determine an absolute humidity of the ambient air from the signals generated by the relative humidity sensor and the first temperature sensor and to control the first heating element to provide a predetermined relative humidity to the flow of breathable gas. A method of humidifying a flow of breathable gas to be provided to a patient includes determining an absolute humidity of ambient air used to form the flow of breathable gas; and controlling a temperature of a supply of water that humidifies the flow of breathable gas to provide a predetermined absolute humidity corresponding to a predetermined temperature and a predetermined relative humidity of the flow to be delivered to the patient.

    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 translation: 设备的方法例如通过间接测量来确定加湿器中的水体的量。 水的量可以通过测量一种或多种性质或特性来确定，从中可以推断出水的量。 可以测量空气流，加湿器和/或水体的特性。 特性可以是例如压力，流速，噪声，振动，温度，电或机械。 这些可以由可以位于加湿器，RPT装置，空气回路或患者接口中的一个或多个传感器来测量。 所描述的方法可以具有优点，例如能够检测水的量而不需要传感器存在于一次性部件中，并且在一些情况下，不引入额外的传感器。

    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.
