ELECTRODE DEVICE Russian patent published in 2017 - IPC A61B5/04 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely to devices for measuring bioelectric potentials, used mainly in medical diagnosis devices. Electrode device comprises dielectric body, in which there dielectric porous contact element is placed consisting of no less than seven porous dielectric plates of same diameter, filled with silver nanoparticles, coated with silver chloride, impregnated with electrolyte and electrically interconnected with silver-containing paste by sintering. On non-working side of upper porous dielectric plate there is a cavity, in which there is layer of silver, which is connected with conductor via current-collecting silver element with help of junction, connected to input of electrographic device. Lower dielectric plate is made with ledge for installation in hole of body bottom. Dielectric plates, located between upper and lower dielectric plates, are made with thickness of no more than 0.8 mm. Electrolyte is following composition, wt%: water 31–35, potassium chloride 10–13, agar-agar 2–3, polyacrylamide 0.5–0.8, glycerine is rest.

EFFECT: technical result: it enables to detect signals of bioelectric activity of different human organs and tissues of nanovolt level in wide range of frequencies from DC to dozens of kHz in real time without filters.
