A wearable device for EEG monitoring

Abstract

The invention discloses a wearable device for EEG monitoring, which includes a mounting frame, a first brain electrode and a second brain electrode, and the mounting frame includes a first horizontal guide rail, a second horizontal guide rail, a third horizontal guide rail, a top plate, a second A connecting arm and a second connecting arm, the first horizontal guide rail and the second horizontal guide rail are ring structures, the third horizontal guide rail is a C-shaped structure, and the first horizontal guide rail, the second horizontal guide rail, the third horizontal guide rail The horizontal guide rails are concentrically arranged directly under the top plate in turn. This wearable device for EEG monitoring can place brain electrodes at any position on the human head, so that when the brain electrodes act on patients with different head shapes, the position is more accurate, and it can Adjust the distance between the brain electrode and the patient's head, so that the brain electrode can be in close contact with any position of the head, preventing the brain electrode from falling off, and also preventing the brain electrode from being in poor contact, improving the stability of the brain wave data .

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
