Inflatable multi-electrode electroencephalogram cap

Abstract

The invention provides an inflatable multi-electrode electroencephalogram cap, relating to the relevant fields of electroencephalogram equipment and electroencephalogram signal processing. The electroencephalogram cap comprises a helmet-type shell, wherein an inflatable inner bag attaches to the inner side of the shell. The inner bag is inflated manually or automatically to swell. A number of electrodes can be placed in the inner bag, the electrodes have the extending and contracting functions so as to be capable of contacting the skin of the to-be-measured part, and the electrodes can be placed according to the international standard collocation method and also can be adjusted according to the special testing. Each electrode is composed of a plurality of electric pins capable of directly contacting the scalp. Each electrode or electric pin can carry out selective monitoring. The electroencephalogram cap further comprises a connecting cable connected to the shell for collecting independent electrode leads.

Description

technical field [0001] The invention relates to the field of EEG equipment and EEG signal processing, and relates to a multi-electrode EEG cap with an inflatable inner bag. Background technique [0002] Electroencephalography (Electroencephalographs, EEG) is a brain waveform recorded and detected by attaching a series of electrodes to the scalp. There have been many significant developments in EEG recording and analysis systems, and they are developing rapidly. A brief list is as follows: digital multi-channel conductance, emergency monitoring EEG monitoring system suitable for both adults and children, amplitude distribution of EEG analysis, computer EEG Topography (Computer EEG Topography, CET) and EEG Topography (BEAM). [0003] These advanced EEG systems and technologies all need to manually place the electrodes on the subject's scalp, so it takes a lot of time. For example, in traditional EEG monitoring, it takes an experienced EEG to place 20 standard electrodes. 20 ...

Problems solved by technology

However, when the hat is worn on the head, these flexible electrodes bend, causing the electrodes to move relative to each other, so the distance between the electrodes changes, making the recording results inaccurate

[0006] The second disadvantage of retractable EEG caps is that in some cases, such as trauma to the head, especially if the skull is injured, the EEG cap is not suitable

Although designing different sizes of EEG caps can alleviate this problem, the adjustability of the retractable EEG caps to the pressure on the skull is still limited, and this problem still exists and has not been resolved.
