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

A control system provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly of the system may include a variable exhaust area such as one defined by overlapping apertures of the assembly or a conduit having a variable gas passage channel. The vent assembly may be formed by nested structures, such as conic or cylindrical members, each having an opening of the overlapping apertures. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid or voice coil, manipulates an aperture of the vent assembly. The actuator may be configured for control by a controller to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection, rebreathing volume calculation and/or leak detection.

Vent arrangement for respiratory mask

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.

Blower with bearing tube

A flow generator includes a housing, a blower structured to generate a flow of pressurized breathable air, and a suspension device to support the blower within the housing and provide a pressure seal between low and high pressure sides of the blower. The suspension device includes a bellows-like portion provided along the perimeter of the blower to absorb shock applied at least radially to the blower and one or more cones provided along upper and/or lower sides of the blower to absorb shock applied at least axially to the blower.

Flow generator

A control system provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly of the system may include a variable exhaust area, such as one defined by gears, radial exhaust revolvers and/or flow diverters for a conduit having a variable gas passage channel. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid, motor or voice coil, manipulates the vent assembly. The actuator may be configured for control by a processor to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection and/or leak detection.

A brushless DC motor including a rotor, a magnet provided to the rotor, a pair of bearings to rotatably support the rotor, a stator assembly that at least partly surrounds the rotor and magnet thereof and adapted to control movement of the rotor, and a bearing tube having an exterior surface and an interior surface that defines a tube interior. The stator assembly is provided along the exterior surface of the tube and the bearings are provided along the interior surface of the tube to support the rotor and magnet within the tube interior. The motor has sample application for use in PAP devices for delivery of positive airway pressure therapy for users or patients.

Positive airway pressure device including blower and support system therefor

A blower includes a housing including an inlet and an outlet, a stationary component provided to the housing, an impeller positioned between the inlet of the housing and the stationary component, a shield portion including an outer edge substantially aligning with or extending beyond an outer edge of the impeller, and a motor adapted to drive the impeller. The housing and the stationary component cooperate to define a volute that directs air towards the outlet, and the housing includes a separating wall constructed and arranged to divide the volute into a high speed airpath region and a low speed airpath region. The outer edge of the shield portion and the separating wall define a gap between the high speed airpath region and the low speed airpath region.
