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.

Methods of detecting a quantity of water in a humidifier

A respiratory treatment device includes a blower for providing flow of breathable gas to a patient and one or more accessory devices. The respiratory treatment device includes active power management to distribute power from a power source that does not have sufficient power to simultaneously power the blower and the accessory devices. The active power management prioritizes power to the blower and limits, based on current measurements of the blower and the accessory devices, the power supplied to the accessory devices to keep the sum of the power drawn at or below the capacity of the power supply. When additional power is available, due reduced power consumption of the blower, the power to one or more accessory devices is raised beyond a target in order to compensate for when power was not supplied to the one or more accessory devices.

Systems and methods for active power management in a medical device

A water reservoir configured to be removably connected to a respiratory pressure therapy (RPT) device has a water reservoir base configured to hold a volume of water to be used for humidification of the breathable air, a water reservoir lid connected to the water reservoir base, a retainer configured to engage with a corresponding portion of a water reservoir dock associated with the RPT device, thus securing the water reservoir to the water reservoir dock, and a portion of the lid being configured to receive a downward force to cause movement of the retainer against the bias of a spring, thus allowing removal of the water reservoir from the water reservoir dock.

Humidifier reservoir

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.

Humidifier tub with flow plate

A respiratory pressure therapy (RPT) device is disclosed for treatment of respiratory-related disorders. The RPT device includes a pressure generator, a pneumatic block, a chassis and a device outlet for delivering a supply of flow of gas to a patient interface. The RPT device also comprises an integrated humidifier including a water reservoir. An RPT device is also disclosed that includes a wireless data communication interface integrated with the housing and configured to connect to another device or a network.

Respiratory pressure treatment system

An apparatus for humidifying a flow of pressurised, breathable air includes varying a first pressure of the flow of breathable gas to vary a level of thermal engagement between the conductive portion of the reservoir and the heater plate, varying a height of the variable portion varies a level of thermal engagement between the conductive portion of the reservoir and the heater plate, use of a humidifier reservoir base component with a maximum water capacity substantially equal to the predetermined maximum volume of water of the humidifier reservoir or the use of intersecting inlet and outlet axes.

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.

Wire heated tube with temperature control system, tube type detection, and active over temperature protection for humidifier for respiratory apparatus

A heating apparatus includes a heating element which converts electrical power to heat energy, a heatable element having a first surface and a second surface, and a dielectric laminate layer between the heating element and the first surface of the heatable element, wherein the dielectric laminate layer is thermally conductive to transfer heat energy from the heating element to the heatable element, and wherein the second surface of the heatable element is configured heat a liquid in a container.

Humidifier and layered heating element

A respiratory treatment apparatus provides respiratory treatment with improved power management control to permit more efficient power consumption and power supply units, such as battery powered operation. In one embodiment, power management prioritizes the flow generator () over other accessories such as the heating elements () of a humidifier () and/or a delivery tube. The flow generator may control operations of the heating elements as a function of a detected respiratory cycle. For example, the timing of operation of the heating elements may be interleaved with the portion of an inspiratory phase of the respiratory cycle to permit the flow generator to operate during a peak power operation without a power drain or with a lower power drain from these components. Operations of distinct sets of components of the system (e.g., different heating elements) may also be interleaved to prevent simultaneous peak power operations.

Power management in respiratory treatment apparatus

An apparatus for treating a respiratory disorder in a patient includes a blower configured to generate a supply of pressurized respiratory air to the patient via an air delivery tube leading to a patient interface; a dock with a heater plate; and a reservoir comprising a conductive portion configured to thermally engage the heater plate.

A system and method is disclosed for performing diagnostics on patient devices (). The patient devices () may include respiratory therapy devices that operate in accordance with instruction sets, such as software or firmware. A server () may maintain a database of diagnostic data () indicating faults in one or more of a plurality of patient devices (). The server () may transmit this diagnostic data () to one or more computing devices (), including identification of faults that have occurred. The server () may also transmit service data to the plurality of patient devices () in order to address the identified faults.
