Nasal cavity resonance rehabilitation instrument and method based on nasal flow measurement and audio-visual feedback technology

The invention discloses a nasal cavity resonance rehabilitation instrument and method based on a nasal flow measurement and audio-visual feedback technology. The instrument comprises a real-time processing unit, a main control unit and a real-time nasal flow audio-visual feedback unit, the real-time processing unit is used for processing nasal flow data when a user generates nasal cavity resonancein real time, the rehabilitation method comprises the following steps that the real-time nasal flow measuring unit measures nasal flow data of a user in real time, the user is required to wear a nasal flow partition plate during measurement, and the partition plate is used for partitioning a nasal cavity channel and an oral cavity channel so that signals of the two channels can be measured respectively to judge whether nasal cavity resonance disturbance exists or not. The rehabilitation mode can be set according to the type of the nasal cavity resonance disorder of the user, so that the suitable rehabilitation conten
