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...

Abstract

The invention discloses a detection system for the sleep apnea hypopnea syndrome. The detection system comprises a fingertip signal acquisition device, a signal conversion module and a data processing module, wherein the fingertip signal acquisition device acquires photoelectric signals, representing blood volume change, in a fingertip blood vessel, converts the photoelectric signals into photoplethysmography data, and wirelessly transmits the photoplethysmography data to the signal conversion module in real time; the signal conversion module receives the photoplethysmography data output by the fingertip signal acquisition device, acquires blood oxygen saturation data, heart rate variability data and pulse rate via filter processing and calculation, and transmits the acquired data to the data processing module; the data processing module outputs sleep state data and respiratory event data based on the photoplethysmography data and the like. The detection system is simple and easy to use, and high in accuracy; the problem that conducting wires are arranged complexly during multi-conduction detection is solved.

Description

technical field [0001] The invention belongs to the field of medical examination, and in particular relates to a convenient, easy-to-use and high-accuracy detection system for sleep apnea syndrome. Background technique [0002] As people pay more and more attention to sleep, sleep medicine has become a new hot spot in clinical medicine. Objective detection of sleep is the basic condition of sleep medicine and sleep-related research. Traditional polysomnography (polysomnography, PSG) is the main method for diagnosing obstructive sleep apnea syndrome (OSAHS). Although PSG is a standard sleep detection technology, it needs to connect and bind many devices and instruments to the subject. The method is complicated and the subject is subject to more constraints. [0003] In recent years, many researchers at home and abroad have devoted themselves to the study of pulse wave characteristics, and provided a method to detect various physiological parameters by using photoplethysmogra...
