FIELD: medical engineering. ^ SUBSTANCE: device has electric current generator, two current-commutating units, the right one and the left one, respectively; three pairs of current electrodes of the first, the second and the third level fixable on arms, legs and two sides of the neck, respectively; controllable potential commutator, two pairs of potential electrodes of the first and second fixation level, detector, analog-to-digital converter and control unit for processing data. Each of the current-commutating units has three switches of connected in series the first, the second and the third level. The device also has current and potential electrode of the fourth level fixable on the front in frontal sinus projection and on nose bridge. The right current-commutating unit has a fourth level switch. Current generator is controllable by control unit for processing data. The switches are done as relays having sealed switching contact group. ^ EFFECT: high accuracy of measurements. ^ 4 cl, 6 dwg, 2tbl |
