METHOD OF NEURAL-LIKE DYNAMIC ELECTRIC STIMULATION AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC A61N1/36 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine, is intended for percutaneous electrical stimulation for providing additional general-purpose action on body physiological systems. Method of neuron-like dynamic electric stimulation consists in generation of pulses with preset frequency, their modulation by duration, amplification, and delivery through the electrodes to the skin surface of the biological object. During stimulation, the rate of change of the capacitive component of the impedance of the object under-electrode skin area is determined, and when the value of the capacitance component of the impedance close to zero is reached, time interval of stimulation is maintained for 3 minutes, after which stimulation is stopped. Rate of change of capacitance component of impedance of object under-electrode area of object is defined as duration of change of first or third half-wave of signal in second phase. Device for realizing the method includes pulse power amplifier, connected to stimulation electrodes applied to biological object, indicator, memory element, microcontroller connected to quartz resonator and two-way communication with memory element, which combines and is intended to control pulse generator through module of programs, modes, functions, connected to control elements and pulse duration modulator, as well as peripheral control module connected to control module, peripheral control module is connected to time counting module, pulse duration modulator and interconnected power amplifier and stimulation unit, wherein module of programs, modes, functions directly and through time counting module is connected to indicator, as well as a feedback pulse duration comparison module, a feedback pulse duration determination module is connected to the feedback pulse converter supplied from the stimulation electrodes, which are connected to the amplifier via a stimulation unit.

EFFECT: method and device enable to reduce level of errors and spread of stimulation parameters due to signal stabilization, as well as broader functional capabilities of the apparatus.
