Embodiment 1

[0039] Example 1 Sleep apnea syndrome detection system

[0040] figure 1 Shown is the structural relationship diagram of the sleep apnea syndrome detection system according to the present invention. The finger tip collection device is a finger cuff structure clamped at the end of the finger, which collects volume 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 provided in the electronic device, and may be a specific component that only performs corresponding functions, or it may be software installed in electronic devices such as mobile phones, tablet computers, and desktop computers. First, the signal conversion module filters the volume photoelectric pulse wave digital signal; then, performs function pr...

Embodiment 2

[0041] Example 2 Data processing flow of sleep breathing syndrome data processing module

[0042] figure 2 It further demonstrates the data processing flow in the data processing module of the present invention. In the data processing module, the photoplethysmographic pulse wave data is calculated as a function, and the pulse rate data, heart rate variability data and blood oxygen are converted from the photoplethysmographic pulse wave data. Saturation data. Analyze the pulse rate data and heart rate variability data together to get the sleep state data. The sleep state data includes the exact time to fall asleep, awake time, deep sleep time and light sleep time during sleep, and whether there is a wakefulness during sleep And other matters, and calculate the continuous sleep time and total sleep time (ie effective sleep time). Combining the photoplethysmography data with the blood oxygen saturation data can calculate the number of apnea events and the number of apnea events i...

Embodiment 3

[0056] Example 3 Fingertip signal acquisition device according to the present invention

[0057] image 3 Shows the structure diagram of the fingertip signal acquisition device in an embodiment of the present invention, a composite volume pulse wave acquisition and processing finger cuff, including a first unit and a second unit that can communicate with each other.

[0058] The first unit includes an upper shell 1, a control circuit unit 2, a sliding seat 3, and a spring contact 4. The upper shell 1 is a hollow structure with an open top, and the control circuit unit 2 is arranged in the upper shell 1. The control circuit unit 2 Including a PCB board and a main control circuit module, a power supply circuit module and a Bluetooth module arranged on the PCB board, the main control circuit module is connected with the power supply circuit module and the Bluetooth module; the power supply circuit module includes a battery 24 and a power management circuit, the battery 24 is fixedly...

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 inspection, and specifically relates to a convenient, easy-to-use and highly accurate 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. The objective detection of sleep is the basic condition for sleep medicine and sleep-related research. Traditional polysomnography (PSG) is the main method to diagnose obstructive sleep apneahypopnea syndrome (OSAHS). Although PSG is a standard sleep detection technology, many devices and instruments need to be connected and tied to the subject. The method is complicated and the subject is more restricted. [0003] In recent years, many researchers at home and abroad have devoted themselves to the study of pulse wave characteristics, and have provided methods for detecting various physiological parameters using photoplethysmography pulse waves. Ph...
