A compact respiratory therapy device suitable for use by a patient during sleep to provide respiratory pressure therapy such as at a pressure between 4-30 cmH2O includes a housing, an inlet, an outlet, a motor including a rotor, and an impeller configured to be rotated by the rotor to deliver a flow of air from the inlet toward the outlet. The impeller includes a set of impeller blades, each impeller blade comprising a leading edge and a trailing edge; and a first shroud and a second shroud, each shroud at least partly defining a flow passage through the impeller, the first shroud comprising a wall defining a periphery of an impeller inlet. The first shroud and the second shroud are configured such that the flow passage is narrower in an axial direction at an outer portion of the impeller than at an inner portion of the impeller.

Impeller for a respiratory device

An elbow assembly for a patient interface includes a swivel component adapted to connect to a patient interface and an elbow component adapted to connect to an air circuit. The swivel component is coupled to the elbow component by a ball and socket joint and a hinge joint which allows the elbow component to pivot relative to the swivel component about a single axis.

Elbow assembly

An apparatus for humidifying a flow of breathable gas includes a water reservoir and a water reservoir dock forming a cavity structured and arranged to receive the water reservoir in an operative position. The water reservoir comprises a reservoir base including a cavity structured to hold a volume of water, the reservoir base including a main body and a thermally conductive portion provided to the main body. The thermally conductive portion comprises a combined layered arrangement including a metal plate and a thin film, the thin film comprising a non-metallic material and including a wall thickness of less than about 1 mm. The thin film is adapted to form at least a bottom interior surface of the water reservoir exposed to the volume of water, and the metal plate is adapted to form a bottom exterior surface of the water reservoir.

CPAP system

Humidification tub bottom

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 water reservoir for an apparatus for humidifying a flow of breathable gas includes a reservoir body forming a cavity structured to hold a volume of liquid. The reservoir body comprises a conductive portion. The conductive portion comprises a thermally conductive material and is adapted to thermally engage with a heater plate to allow thermal transfer of heat to the liquid. The conductive portion includes a peripheral interfacing portion structured and arranged to connect the conductive portion to one or more walls of the reservoir body. The peripheral interfacing portion includes an intermediate portion and an end portion. The end portion is bent so as to be at least inclined with respect to the intermediate portion to reduce a risk of leakage caused by cracks within a critical area of a thickness of the one or more walls due to a presence of a sharp edge at the end portion.

A compact respiratory therapy device suitable for use by a patient during sleep to provide respiratory pressure therapy such as at a pressure between 4-30 cmH2O includes a housing, an inlet, an outlet, a motor including a rotor, and an impeller configured to be rotated by the rotor to deliver a flow of air from the inlet toward the outlet. The impeller includes a set of impeller blades, each impeller blade comprising a leading edge and a trailing edge; and a first shroud and a second shroud, each shroud at least partly defining a flow passage through the impeller, the first shroud comprising a wall defining a periphery of an impeller inlet. The compact respiratory therapy device is configured to deliver the flow of air from the outlet for delivery to the patient at a pressure between 4-30 cmH2O at an overall sound power level of less than 50 dB(A) thereby reducing any disturbance to a quality of sleep for the patient. A diameter of the impeller is less than 50 mm. The first shroud and the second shroud are configured such that the flow passage is narrower in an axial direction at an outer portion of the impeller than at an inner portion of the impeller; and a diameter of the impeller inlet is at least 50% of the diameter of the impeller.

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

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.
