FIELD: medicine; neurology; physiotherapy. ^ SUBSTANCE: trans-cranial electrical stimulator has pulse oscillator with frequency of influence of 77+-7,0 Hz, output current level regulator, output current meter, voltage stabilizer, power battery, four electrodes. According to first version of device, pulse oscillators are introduced in it additionally, which pulse oscillators have frequencies of influence of 10+-1,0 Hz and 500+-50,0 Hz, smoothing filter, two keys, device for fastening electrodes and master oscillator with transformer amplifier, which is connected with rectifier. Output of power battery is connected with input of voltage stabilizer. Output of voltage stabilizer is connected with inputs of output current level regulators, of pulse oscillators and of master oscillator. Output of output current level regulator is connected with input of first key. Output of rectifier is connected with second input of first switch. Output of the first switch is connected with output current metering devices and with electrodes. Output of second key is connected with input of smoothing filter; output of smoothing filter is connected with transformer amplifier. According to the other version, computer, standard interface of LPT-port, commutator and three galvanic optical separations are introduced into device additionally besides described common members. Input of commutator is connected with outputs of three pulse oscillators. Output of commutator is connected with input of first switch. Computer is connected to commutator through standard interface LPT-port and galvanic optical separations. Device for fastening electrodes of trans-cranial electrical stimulator has headband in form of helmet made on arm-pieces made of spring ribbon spiral in form of arcs, bent along radius to follow shape of head, and of electrodes attached to headband. Arm-pieces are provided with openings, lockers and grooves for fastening and moving electrodes. Electrodes are made in form of small plates closed with cap from the top, which caps are made of electric-insulated material. Electrodes are movable mounted in grooves of holders by means of slugs on caps. Efficiency of treatment can be improved at more distinct normalization of hemodynamic disturbances and optimization of neurodynamics in structures of libicoreticular complex. ^ EFFECT: improved efficiency of electrophoresis; simplified procedure. ^ 3 cl, 4 dwg, 6 att |
