AI Technical Summary
Technical Problem
Existing CPAP systems have a significant impact on patients during use due to shock, noise, and vibration. Furthermore, the equipment is bulky and noisy, making it difficult to adapt to different facial shapes.
Method used
A miniaturized CPAP system was designed, including a patient interface and a blower, which is supported on the patient's head by a headband or padding, employs a cushioning structure to reduce vibration and noise, adapts to different facial shapes, and uses a portable blower and diagnostic functions.
Benefits of technology
It reduces impact on patients, lowers noise and vibration, adapts to a wider range of facial shapes, and provides portability and comfort.

Abstract
A PAP system is disclosed. A blower includes a housing including a proximal opening and a distal opening coaxially aligned, a stator component disposed to the housing, a pusher positioned between the proximal opening of the housing and the stator component, the pusher including a plurality of pusher vanes, and a motor adapted to drive the pusher, wherein the stator component includes a plurality of air directing grooves along an outer surface thereof, leading edges of the air directing grooves extending tangentially outward from outer tips of the pusher vanes and configured to collect air exiting the pusher vanes and direct it from substantially tangential to substantially radial by separating air from the pusher and directing air along a curved path toward the distal opening such that the air flow becomes substantially laminar.
