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 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.

Apparatus for providing air at positive pressure for respiratory therapy to a patient includes a pneumatic block including at least first and second blower sub-assemblies and a common chassis assembly configured to support each of the at least first and second blower sub-assemblies. The at least first and second blower sub-assemblies are different structurally from one another in at least one aspect. Each of the at least first and second blower sub-assemblies includes a corresponding blower configured to produce a flow of air at a therapeutic pressure. The common chassis assembly and the first blower sub-assembly form a first configuration of the pneumatic block, and the common chassis assembly and the second blower sub-assembly form a second configuration of the pneumatic block. The air flow path and the chamber arrangement of the first configuration is different than the air flow path and the chamber arrangement of the second configuration.
