specific Embodiment

[0036] figure 2 is a schematic diagram of the workflow of the system of the present invention; image 3 It is a wearing schematic diagram of the device / equipment included in the system of the present invention. Such as figure 2 and image 3 As shown, the system of this embodiment collects two kinds of signals from the human body, namely ECG and blood oxygen signals. The ECG collection module 110 uses wearable smart fabrics to measure ECG signals. The two ECG electrodes place the heart between the connecting lines of the two ECG electrodes to collect real-time ECG signals. The blood oxygen collection module 120 is worn on the wrist, and uses a photoelectric sensor to perform photoplethysmography (PPG) measurement. According to Lamber-Beer's law, the absorbance of a substance at a certain wavelength is proportional to its concentration. When light of a constant wavelength is irradiated on human tissue, the light measured after absorption, reflection and attenuation by hum...

Abstract

The invention discloses a sleep apnea hypopnea syndrome detection system and method. The system includes a data acquisition device (100) and an analysis processing device (200); the data acquisition device (100) comprises an electrocardiosignal acquisition unit (110) and a blood oxygen signal acquisition unit (120) which are used for acquiring electrocardiosignals and blood oxygen signals of the human body respectively; the analysis processing device (200) comprises a calculation unit (210) which is used for extracting respiration signals from the electrocardiosignals, identifying the apnea and hypopnea states in real time according to the respiration signals and the blood oxygen signals, calculating the apnea hypopnea index and analyzing the sleep state of the human body to obtain an analysis result. The system has the advantages of being easy to operate, convenient to wear, good in comfort and high in real-time performance.

Description

technical field [0001] The invention relates to the technical field of human health status monitoring, in particular to a sleep apnea hypopnea syndrome detection method and system. Background technique [0002] Sleep apnea hypopnea syndrome (Sleep Apnea Hypopnea Syndrome, hereinafter referred to as SAHS) refers to a sleep apnea and (or) hypopnea repeatedly occurring in sleep due to various reasons. It is clinically defined as more than 30 repeated episodes of apnea during sleep every night or the sleep apnea-hypopnea index (AHI) ≥ 5 times / hour, where the sleep apnea-hypopnea index (AHI) refers to the number of breaths per hour of sleep. Number of pauses to increase and decrease ventilation. Apnea refers to the complete cessation of oronasal breathing airflow for more than 10 seconds during sleep; hypopnea refers to the reduction of respiratory airflow intensity by more than 50% compared with the baseline level during sleep, accompanied by a decrease in blood oxygen saturati...
