Abstract:
A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.
Abstract:
A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.
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 continuous positive airway pressure (CPAP) device to non-invasively treat a sleep disordered breathing disorder of a user may include a humidifier indicator backlight configured to indicate operation of a humidifier and a heated tube, the humidifier indicator backlight having an on state and an off state, a first backlit color and a second backlit color, and a first brightness and a second brightness, and the humidifier indicator backlight being configured to change between the first backlit color and the second backlit color and/or between the first brightness and the second brightness in response to user adjustment of a humidifier setting and/or a heated tube setting.
Abstract:
An apparatus for treating sleep disordered breathing may include: a flow generator to deliver a supply of air at positive pressure to a patient; a user interface, the user interface comprising: a display configured to display a plurality of screens; and a set of controls; and a controller in communication with the user interface and configured to control operation of the flow generator, wherein the flow generator is configured to couple with at least one accessory device and during a first mode of operation of the flow generator the controller determines a first screen of the plurality of screens to display on the display based on the at least one accessory device, the first screen of the plurality of screens being configured to enable adjustment of one or more parameters related to the operation of the at least one accessory device or the flow generator using the set of controls.
Abstract:
A flow generator and humidifier construction is described, including a flow generator construction adapted to reduce noise output compared to known flow generators of comparable size. The flow generator includes a chassis forming first and second muffler volumes and a venturi-shaped connection portion, and a metal/polymer composite material blower enclosure which suppresses noise from the blower. The flow generator may be programmed to include a reminder system including a menu from which the user may request a reminder to take specific action, e.g., replace a component, call a physician, and/or enter patient data card, etc.
