Portable sleep monitoring system based on ear EEG

Abstract

The invention discloses a portable sleep monitoring system based on ear EEG. The system comprises two ear-hanging electrode modules, an EEG acquisition module, a mobile terminal module and an analysis module, wherein the two ear-hanging electrode modules are arranged on two ears, and each ear-hanging electrode module comprises a plurality of acquisition electrodes and a reference electrode; the EEG acquisition module is connected with the ear-hanging electrode modules and used for acquiring EEG signals from the acquisition electrodes and the reference electrodes and performing preliminary signal processing to obtain processed ear EEG signals; the mobile terminal module is used for receiving the processed ear EEG signals, displaying waveforms in real time and transmitting the ear EEG signals to the analysis module after acquisition is completed; the analysis module performs sleep stage division and characteristic wave detection on the ear EEG signals and generates a sleep analysis report. The sleep monitoring system adopts ear-hanging electrodes, can be worn autonomously, is portable and high in fitting degree and has higher sensitivity and accuracy.

Description

technical field [0001] The invention belongs to the technical field of sleep monitoring, in particular to a portable sleep monitoring system based on ear EEG. Background technique [0002] Sleep monitoring is of great significance in the diagnosis and treatment of sleep disorders, various mental disorders and cognitive disorders related to brain aging, and continuous multi-day sleep EEG monitoring is becoming more and more important in healthy and diseased people. Ear EEG (electroencephalo-graph, electroencephalogram) is an ear-based EEG acquisition technology. Recent studies have shown that it can be used as a substitute for standard EEG to achieve sleep stage division and sleep characteristic waveform detection. It overcomes the shortcomings of a large number of scalp electrodes for head EEG, and time-consuming and labor-intensive electrode positioning and placement. It has the advantages of high compliance and comfort, making it more suitable for the monitoring of one-nig...

AI Technical Summary

Problems solved by technology

[0004] However, the accurate detection of brain activity by ear EEG in sleep state must undergo comprehensive and systematic debugging, especially the determination of the positions of acquisition electrodes and reference electrodes, otherwise it will be difficult to replace the accuracy of data information obtained by head EEG

In addition, there are relatively few studies on ear EEG at present, and there is a lack of effective analysis methods and parameters for sleep stage division and feature wave extraction based on ear EEG, which hinders the development of ear EEG.
