Embodiment 1
[0039] Example 1 Sleep apnea syndrome detection system
[0040] figure 1 Shown is a structural relationship diagram of the sleep apnea syndrome detection system according to the present invention, the fingertip acquisition device is a finger cuff structure clamped at the end of the finger, which collects volumetric photoelectric pulse wave (PPG) signals in real time through photoelectric signals, and The photoelectric signal is directly converted into a digital signal, and then the volume photoelectric pulse wave digital signal is transmitted to the signal conversion module through a wireless connection. The signal conversion module is set in the electronic device, and may be a specific component that only performs corresponding functions, or may be software installed in electronic devices such as mobile phones, tablet computers, and desktop computers. Firstly, the signal conversion module performs filter processing on the digital volume photoelectric pulse wave signal; the...
Embodiment 2
[0041] Example 2 Data processing flow of sleep apnea detection syndrome data processing module
[0042] figure 2 Further demonstrates the data processing flow in the data processing module of the present invention, performs function calculation on the photoplethysmography data in the data processing module, and converts the pulse rate data, heart rate variability data and blood oxygen from the photoplethysmography data saturation data. Combining pulse rate data and heart rate variability data to analyze sleep status data, sleep status data includes exact time to fall asleep, wake up time, deep sleep time and light sleep time during sleep, and whether there is a slight awakening during sleep etc., and calculate the continuous sleep time and the total sleep time (ie effective sleep time). Combining the photoplethysmography data with the blood oxygen saturation data can calculate the apnea event and the number of apnea events in the acquisition cycle. Generally, when apnea h...
