|1. (WO2018047451) CPAP DEVICE|
|Applicants:||NIDEC COPAL ELECTRONICS CORPORATION
Provided is a continuous positive airway pressure (CPAP) device which is small in size, and for which the detection accuracy of a sensor can be improved. A fan unit 17 produces an air flow. A pressure difference generating member 32 causes a pressure difference in the air flow. A sensor detects the difference between an upstream air pressure and a downstream air pressure of the pressure difference generating member 32. A straightening plate 31 is provided between the fan unit 17 and the pressure difference generating member 32, and straightens the air flow produced by the fan unit 17. The straightening plate 31 is provided with a first fin 31b and a second fin 31c that are disposed parallel to the air flow, and a lattice-shaped third fin 31d that is disposed downstream of the first fin 31b and the second fin 31c, and that allows the air flow that has passed by the first fin 31b and the second fin 31c to pass therethrough.
