Abstract

The invention relates to a split pressing type multifunctional electroencephalogram cap, which at least comprises a cap body; the cap body is worn on the head of a patient and is composed of a plurality of split connecting blocks, wherein each split connecting block comprises a first unit and a second unit which are used for bearing brain electrodes for detecting electroencephalogram signals of the corresponding area of the head of the patient; the positions of the first unit and the second unit can be changed relatively; the first unit and the second unit are both close to the cambered surface of the head of a human body; the first unit of the split connecting block is movably connected to the second unit through a driving system arranged between at least one part of areas of the first unit and the second unit, wherein the brain electrodes arranged on the first unit and the second unit at least can follow relative movement of the first unit and the second unit in the first direction to be close to and / or far away from an electroencephalogram detection area located on the head of the patient.

Description

technical field [0001] The invention relates to the technical field of electroencephalogram detection, in particular to a split-and-press multifunctional electroencephalogram cap. Background technique [0002] EEG is a method of collecting the summation of brain bioelectrical signals on the surface of the scalp. It can record the changes in electrical waves in brain activity. It is the sum of changes in the potential of nerve cells and the overall reflection of changes in brain nerve cells in the cerebral cortex or the surface of the brain. It has the characteristics of spontaneity, rhythm, and randomness. Spontaneity means that the EEG exists all the time, and the amplitude is 5-200uV. Negative random variation. Collecting EEG from different brain regions can obtain more information. Brain waves are divided into δ, θ, α, β, and γ according to different frequencies. During sleep, σ, λ, and κ-complex waves, μ and other waveforms, EEG plays a very important clinical role in ...
