The apparatus may comprise first and second blower suspensions for holding opposite ends of the blower. The blower suspension(s) may be flexible and in tension. The apparatus may comprise one or more connector anchors for anchoring a longitudinal middle section of the flexible connector to another part of the apparatus.

Respiratory pressure therapy device

The present technology is directed to a respiratory pressure therapy system, that includes a plenum chamber pressurisable to a therapeutic pressure above ambient air pressure, a seal-forming structure to form a seal with an entrance to the patient's airways to maintain said therapeutic pressure in the plenum chamber throughout the patient's respiratory cycle in use, a positioning and stabilising structure constructed and arranged to provide an elastic force to hold the seal-forming structure in a therapeutically effective position on the patient's head, a blower configured to generate the flow of air and pressurise the plenum chamber to the therapeutic pressure, the blower having a motor, the blower being connected to the plenum chamber such that the blower is suspended from the patient's head and the axis of rotation of the motor is perpendicular to the patient's sagittal plane, and a power supply configured to provide electrical power to the blower.

Respiratory pressure therapy system

A blower includes a housing including an inlet and an outlet, a bearing-housing structure provided to the housing and adapted to rotatably support a rotor, a motor provided to the bearing-housing structure and adapted to drive the rotor, and an impeller provided to the rotor. The bearing-housing structure includes a bearing shaft having a bearing surface that rotatably supports the rotor. The bearing shaft provides only a single bearing of the non-ball bearing type for the rotor.

PAP system blower

Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder includes a first chamber, a second chamber, at least one inlet tube structured and configured to allow ambient air to enter the first chamber, at least one flow tube structured and configured to allow air to pass from the first chamber to the second chamber, and a blower structured and configured to produce a flow of air at positive pressure. The blower is positioned in the first chamber and structured and configured to receive air from the second chamber. The blower includes a housing structured and configured to sealingly separate air flow through an interior of the housing from the first chamber. The at least one inlet tube is axially spaced from the at least one flow tube.

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

A respiratory apparatus evaluates accuracy of a pressure sensor, such as when only a single pressure sensor is provided. The accuracy of the pressure sensor may be assessed based on pressure measurement obtained from the pressure sensor and a subordinate or secondary characteristic of the respiratory device such as altitude or atmospheric pressure. A controller or processor may calculate the altitude of the respiratory device based in part on the pressure measurement. In some embodiments, the assessment of the pressure sensor may involve an evaluation of the calculated altitude. In some cases, the assessment of the pressure sensor may involve determining an estimated pressure based on a calculated altitude, and comparing the pressure measurement obtained from the pressure sensor with the estimated pressure.

Pressure sensor evaluation for respiratory apparatus

A respiratory pressure therapy (RPT) system may include a housing portion forming a plenum chamber pressurizable to a therapeutic pressure; a seal-forming structure constructed and arranged to with a region of the patients face; a positioning and stabilising structure constructed and arranged to provide an elastic force to hold the seal-forming structure in a therapeutically effective position on the patients head; a blower configured to pressurize the plenum chamber to the therapeutic pressure; a vent assembly configured to discharge gas from a plenum chamber to atmosphere; a sensor port positioned downstream of the vent assembly such that the sensor port is in pneumatic communication with the air within the plenum chamber in any position of the vent assembly; and a sensor in pneumatic communication with the air within the plenum chamber via the sensor port.

An impeller for use in a centrifugal blower, the impeller includes a hub defining an axis of rotation for the impeller; a plurality of inclined blades, the plurality of inclined blades extending away from the hub; and a plurality of reverse inclined blades, the plurality of reverse inclined blades extending away from the hub. Each of the plurality of inclined blades are joined to an adjacent inclined blade at least in part by a reverse inclined blade.

Impeller with inclined and reverse inclined blades

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

A blower includes a stationary portion including an inlet and an outlet, a rotating portion provided to the stationary portion, and a motor adapted to drive the rotating portion. The inlet and outlet are co-axially aligned. The stationary portion includes a housing, a stator component provided to the housing, and a tube providing an interior surface. The rotating portion includes one or more bearings that are provided along the interior surface of the tube to support a rotor within the tube. In an embodiment, the blower is structured to supply air at positive pressure.
