摘要： 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.

摘要： Spirometer, mouthpiece tube and inspection method thereof. The spirometer includes at least the mouthpiece tube and an ultrasound detector configured to detect the ultrasound generated by the gas flowing through the mouthpiece tube, wherein the mouthpiece tube has a shell having an opened end, a closed or opened end, and an ultrasonic generator configured to be inserted into different portions of the shell in different situations. Therefore, by inserting the ultrasonic generator into different portions of the shell during expiration and inspiration, the gas flow during expiration and inspiration may be transformed into the ultrasonic signal and then maybe detected and analyzed.
