Wearable device for electroencephalogram monitoring

Abstract

The invention discloses a wearable device for electroencephalogram monitoring, comprising a mounting frame, a first brain electrode and a second brain electrode. The mounting frame includes a first horizontal guide, a second horizontal guide, a third horizontal guide, a top plate, a first connection arm and a second connection arm. Both the first horizontal guide and the second horizontal guide are of circular structure; the third horizontal guide is of C-shaped structure; the first horizontal guide, the second horizontal guide and the third horizontal guide are arranged right below the top plate sequentially and concentrically. The wearable device for electroencephalogram monitoring has the advantages that the brain electrodes are placed in any position on the human head; when the brain electrodes act on patients having different head sizes, the positions are more precise; distances from the brain electrodes to a patient's head are adjustable so that the brain electrodes may tightly contact any position of the head, falling of the brain electrode is prevented, poor contact of the brain electrodes is also prevented, and electroencephalogram data stability is improved.

Description

technical field [0001] The invention relates to the technical field of EEG monitoring, in particular to a wearable device for EEG monitoring. Background technique [0002] At present, the technical method of detecting children's EEG is EEG (Electroencephalography), which is often used as an auxiliary examination for brain neuropsychiatric diseases. EEG can continuously record the overall collective activity of cerebral cortex neurons, with the prominent characteristics of frequency rhythm and periodicity, reflecting the regulatory behavior of cerebral cortex neurons, used to examine the physiological function of the brain, and reflect the pathological changes of the brain. From fetus, newborn to childhood, the development of brain waves is based on the anatomical development of brain tissue and the physiological and biochemical maturity of brain tissue. The growth and development of the nervous system determines the characteristics of brain waves in each period. Children wi...

Problems solved by technology

[0003] The EEG cap is an accessory connected to the human head in EEG monitoring. The traditional EEG cap is made of rubber strips and elastic bands. Due to the individual differences in the shape of the patient's head, the size and shape of the electrode cap must be adjusted every time, affecting the In addition, when placing brain electrodes, the approximate position can only be roughly estimated according to the 10-20 rule. Because the size of each person's head is inconsistent, it is inconvenient to use a ruler to measure, and it is impossible to accurately quantify the placement of the electrodes, resulting in The collected graphics are not necessarily the corresponding positions required by the system, which affects the diagnostic effect; moreover, the electrode cap is fixed by a rubber band or an elastic band. Long-term use may easily cause deformation of the fixing band, making the electrode cap looser. It is easy to cause the detachment of brain electrodes
