NON-INVASIVE NEUROSTIMULATION SYSTEM Russian patent published in 2014 - IPC A61N1/36 A61N1/08 A61N1/18 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to neurostimulation apparatuses. An apparatus comprises a device having a pulse generator for its supply on skin, a control unit, a probe with a number of electrodes connected to the control unit; the device is configured to determine a relative skin impedance, to localise an area of treatment on the basis of the relative skin impedance and to supply automatically a therapeutic pulse sequence on the basis of the pre-set relative skin impedance. According to the second version, the apparatus additionally comprises a gripping mechanism having a number of skin-contacting electrodes; the control unit is presented to determine a relative impedance of at least two of the whole number of electrodes for recording electrode-contacting skin impedance and to supply stimulation pulses to the electrodes on the basis of the recorded skin impedance. According to the third version, the probe comprises a number of spaced electrodes placed in a matrix; the matrix comprises a number of pairs of electrodes, and each pair of electrodes comprises neighbour electrodes having opposite polarities; the apparatus is configured to measure the skin impedance by the number of electrodes, to determine the relative impedance of the number of pairs of electrodes, to identify the area of treatment on the basis of the relative impedance, to transmit the pulse sequence into the area of treatment on the basis of the relative impedance of the pair of electrodes and to adjust the parameters of the pulse sequence in response to measuring the relative impedance of the pair of electrodes. According to the fourth version of the embodiment, the gripping mechanism comprises a number of electrodes comprising at least one first pair of electrodes mounted on the first probe to travel along the patient's skin to localise the active area on the basis of the skin impedance, and at least one second pair of electrodes mounted on the second probe to supply a pulse into the active area, while the control unit has at least one pre-set therapeutic parameter for setting variables of the generator to generate a pre-set pulse group and configured to provide a graphic selection of the above at least one pre-set therapeutic parameter by an operator by means of an interface.

EFFECT: using the invention enables to extend the range of technical aids for therapeutic neurostimulation.
