US 11,925,454 B2 · Respiratory function testing system and respiratory function testing method thereof

Abstract

A respiratory function testing system includes an air transforming device, a sound reception device and an operation device. The air transforming device is configured to collect exhaled and/or inhaled air for a predetermined period and generate a wide frequency range sound signal according to the collected respired air. The wide frequency range sound signal at least contains an ultrasonic signal. The sound reception device is configured to receive and record the wide frequency range sound signal as an audio file. The operation device is in communication with the sound reception device and is configured to receive and compute the audio file to generate a respiratory function parameter. Besides, the recorded wide frequency range sound signal may be converted into a spectrogram for further applications, and the computation of the audio file can be replaced by analyzing the spectrogram. A respiratory function testing method corresponding to the respiratory function testing system is also provided.

Dependent claims

A respiratory function testing system, comprising:

an air transforming device, configured to collect a user's respired air for a predetermined period and generate a wide-frequency sound signal according to the collected respired air, wherein the wide-frequency sound signal comprises an ultrasonic signal;
a sound reception device, configured to receive and record the wide-frequency sound signal, and to store the recorded wide-frequency sound signal as an audio file;
and
an operation device, configured to communicate with the sound reception device and to receive the audio file;
wherein the operation device is configured to convert the audio file into a spectrogram;
wherein the operation device is configured to use a built-in AI module to decide automatically Signal Onset X1 of the spectrogram, Signal Offset X2 of the spectrogram, Signal Duration W of the spectrogram, and frequency range Y1/Y2 of the spectrogram, wherein the built-in AI module is trained by repeatedly collecting different respired air during different predetermined periods and comparing different spectrograms with respiration results.
