DEVICE FOR NONINVASIVE ELECTRIC STIMULATION OF THE SPINAL CORD Russian patent published in 2017 - IPC A61N1/36 

FIELD: medicine.

SUBSTANCE: electro stimulator (15) of the spinal cord contains five stimulation channels (1-5) with an electrode system. Each channel includes a series-connected voltage converter (7), a current generator (6) and an output signal generator (8) and is configured to generate rhythmic modulated bipolar, rhythmic monopolar pulses of rectangular shape, rhythmic or single unmodulated monopolar pulses of rectangular shape, In the range 1-99 Hz, with a current amplitude of 1 to 300 mA and a modulation frequency of 4 to 10 kHz. The inputs of each channel are connected to a microcontroller (9) which is connected to the display unit (10), the control elements (11) and the radio module (12) and is configured to trigger at least one stimulation channel, independently each of the stimulation channels, control of each of the stimulation channels with pulse parameters selected from at least the shape of the pulses, the stimulation frequency with a step of changing the frequency of 1 Hz, the modulation frequency with a step change in frequency of 1 kHz, the amperage with a step change of 1 mA, pulse 0.1 ms step changes.

EFFECT: improving the efficiency of the rehabilitation process for patients with spinal cord pathologies in patients with severe motor disorders, including the restoration of voluntary movements in full, without surgical intervention to implant electrodes, without the risks associated with a foreign body implanted on the surface of the spinal cord, and also to expand the arsenal of technical means intended for percutaneous stimulation of the spinal cord.
