Description

{A put on type instrument for measuring brain waves}

The present invention relates to a wear mechanism for measuring EEG, and more particularly to a wear mechanism for measuring EEG that can shorten the measurement waiting time and can be in close contact with each sensor uniformly to the measurement target site.

In general, EEG is a relatively weak signal of the biological signal. Therefore, when examining the electroencephalogram using an EEG, the distortion of the signal is increased even with a slight noise, so that the measurement part and the sensor part should be in close contact with each other to prevent the noise.

To do this, a gel is inserted between the skin of the measuring part (ie, the scalp) and the sensor. Usually, a brain-shaped cap (Cab), which is made of a mesh type, is worn, and then the gel is inserted through the probe of the cap with a syringe. After pressing the probe, the sensor and the measurement part should be as close as possible and measured.

By the way, the conventional cap for EEG has a problem that it takes a lot of time to prepare because you have to put the gel after wearing on the head.

In addition, the cap for the EEG, the cap is fastened to both jaws after wearing, but due to the structural characteristics consisting of a mesh, which is a material lacking flexibility, the contact of the entire sensor electrode is not uniform, and some electrodes are well adhered There was a problem.

Accordingly, the present invention has been made in order to solve the problems of the prior art as described above, it is possible to shorten the measurement waiting time by pre-filling the gel in the body of the sensor and measuring the brain wave and the general hat as a body of the wear mechanism An object of the present invention is to provide a wear mechanism for measuring EEG that can be easily applied to the shape and material of the.
