Non-fixed-contact-type electrocerebral acquisition system and information acquisition method thereof

Abstract

The invention discloses a non-fixed-contact-type electrocerebral acquisition system and an information acquisition method of the non-fixed-contact-type electrocerebral acquisition system, wherein an acquisition unit array comprises an electrocerebral reference-potential unit, a plurality of electrocerebral acquisition units and a plurality of temperature acquisition units, wherein the electrocerebral acquisition units, the temperature acquisition units and the electrocerebral reference-potential unit are all arranged on an electrode-array fixing device and are respectively used for acquiring electrocerebral signal data, acquiring temperature signal data and providing a reference potential for each electrocerebral acquisition unit. According to the non-fixed-contact-type electrocerebral acquisition system and the information acquisition method, electrodes can be tightly stuck to the skin of a human body to accurately acquire electrocerebral signals, extract characteristic information in real time and transmit the characteristic information to a wireless receiving end through radio frequency without using any organic solvent. By adopting the myoelectric acquisition method described by the invention, an electrocerebral acquisition product has the characteristics of simplicity and convenience in wearing or picking operation, high acquisition speed and greater application value, and the quantity of the electrodes can be increased or decreased at all times and places without modifying system hardware and software.

Description

technical field [0001] The invention relates to a collection, processing and transmission instrument of bioelectrical signals in the technical field of electrophysiological diagnosis equipment, in particular to a non-fixed contact EEG collection system and an information collection method thereof. Background technique [0002] With the continuous advancement of science and technology and the increasing number of hospital patients, portable medical equipment has emerged as the times require, which are safe and reliable medical equipment that people can use without leaving home. [0003] EEG signals are the overall reflection of the electrophysiological activities of brain nerve cell groups. Different states and etiologies of the brain will cause changes in EEG signals in different regions or frequency bands of the brain, resulting in different patterns of EEG signals. Electroencephalogram examination is now playing an important role in the clinical diagnosis of neuropsychiatr...

AI Technical Summary

Problems solved by technology

[0004] However, the usual EEG signal acquisition system is cumbersome to use, high in cost, and usually needs to wear an information recording device, and needs to apply a conductive medium on the skin, which is worth the poor experience of patients.
