FIELD: medical equipment. ^ SUBSTANCE: device is used for measuring electric resistance of biologically active points at human body as well as for medicinal treatment and corporal express diagnostics. Frequency of influence signal is found precisely as well as modes of influence of signal on biologically active points by random settled shape alternating and direct currents with constant or constant-free component. Device has quartz oscillator, programmed frequency divider connected with output of quartz oscillator, addressing unit connected with output of programmed frequency divider, intermediate memory connected with output of addressing unit, digit-to-analog converter, linear interpolation unit, amplitude corrector, constant component regulator, analog adder, scanning detector. Addressing unit has interval register, digital adder and register-accumulator. Amplitude corrector has amplitude register and digit-to-analog multiplier. Constant component regulator has constant component register and analog-to-digital converter. Scanning detector has scanning control register, multi-electrode, peak detector and analog-to-digital converter. Multi-electrode has analog switch, current switch and amplifier. Programmed frequency divider, addressing unit, intermediate memory, amplitude corrector, constant component regulator and scanning detector are connected with computer system. ^ EFFECT: improved precision; widened operational capabilities. ^ 6 cl, 6 dwg |
