Measuring module apparatus of a cerebral activity using Transcranial Current Stimulation and Functional near-infrared spectroscopy

摘要

The present invention provides a module device for measuring brain activity by multi-channel transcranial current stimulation and functional near-infrared spectroscopy, comprising: tCS + fNIRS goggles worn on the head of a patient to measure brain activity of the patient; A t-shaped tCS + fNIRS module case each of which is attached to a plurality of perforated perforations at equal intervals to the tCS + fNIRS goggles, the lower portion of which is opened and the upper portion of which is closed; A tCS + fNIRS module having a piston shape which is vertically moved in the tCS + fNIRS module case, the tCS + fNIRS module having a lower end in contact with the scalp; A module guide fixing cap installed on a lower outer circumferential surface of the tCS + fNIRS module to fix the tCS + fNIRS module; A plurality of module guide connecting members coupled to the tCS + fNIRS module at the bottom of the module guide fixing cap and connected to other adjacent tCS + fNIRS modules in all directions; A 5 pin cable connected through the side of the tCS + fNIRS module case, and the USB C connector for connecting the two 5-pin cable, characterized in that consisting of. In the present invention, since the electrode for applying the transcranial current stimulation and the electrode for measuring the brain activity are integrated, it is possible to obtain a signal measuring the brain activity at the same position, and to apply a transcranial AC and DC stimulation. have. In addition, a spring is attached to the rear surface of the electrode of the brain hemodynamic measurement using functional near-infrared spectroscopy to push the optical fiber with elastic force, thereby increasing adhesion to the scalp and minimizing the subject's scalp stimulation. In addition, the size of the two optical fiber and the object supporting it is less than 6mm, it is possible to minimize the effect of the hair, which makes it difficult to contact the scalp, in the case of dry can avoid contact with the scalp by the hair, when wet The unevenness is used to fix the sponge, and the elasticity of the sponge and the elasticity of the cap (Cap) work together to have an effect that smoothly causes transcranial alternating current and direct current stimulation on the scalp surface.
