    摘要： 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.

    摘要： Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patients face surrounding an entrance to the patients airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patients respiratory cycle in use. The positioning and stabilising structure may comprise a front hoop arranged to contact, in use, at least a region of the patients head superior to an otobasion superior of the patients head and a rear strap. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of the front hoop and the rear strap relative to the patients head, the adjustment mechanism being arranged in a single operation to adjust both the front hoop and rear strap to enable the positioning and stabilising structure to fit different size heads.

    摘要： A head-mounted display system includes a head-mounted display unit and a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operational position over a user's face in use. The positioning and stabilising structure includes a rear support structure adapted to contact posterior regions of a user's head and at least one connector structured and arranged to interconnect the rear support structure to the head-mounted display unit. The rear support structure is in the form of a hoop comprising an occipital portion configured and arranged engage the user's head along a portion of the occipital bone adjacent a junction where the neck muscles attach to the occipital bone in use.

    摘要： A patient interface structure includes a cushion configured to sealingly engage the patient's face and a front that is more rigid than the cushion. The cushion includes a forward opening, a rearward opening that is opposite the forward opening and a continuous sealing surface. The continuous sealing surface has a mouth sealing portion configured to seal around the patient's mouth and a nasal sealing portion configured to seal around both of the patient's nasal airways. The front plate includes an air inlet configured to both receive the pressurized respiratory gas and secure headgear to the patient interface structure. In addition, the nasal sealing portion includes at least one aperture that is separate from the rearward opening. Also, the front plate, the mouth sealing portion and the nasal sealing portion together form a common chamber.
