DEVICE FOR FUNCTIONAL DIAGNOSIS Russian patent published in 1999 - IPC

FIELD: devices for functional diagnoses based on measurement of value of electric skin resistance of biologically active points. SUBSTANCE: device has active and common electrodes connected to A/D and D/A converters. Connected to data buses are inputs of data of D/A converter and register, data outputs of A/D converter, outputs of instruction codes of instruction selector and the first inputs-outputs of buffer amplifier whose second inputs-outputs are connected to control bus connected with inputs-outputs of on-line memory unit, fixed memory unit, the first inputs-outputs of microcontroller and inputs of address decoders whose outputs are connected with control inputs of buffer amplifier, A/D and D/A converters, register and instruction selector whose date inputs are connected with outputs of control panel of operator. Outputs of instruction selector are connected with inputs of interruption and reset of microcontroller whose clock input and readiness input are connected, respectively, with output of master oscillator and with output of A/D converter. Indicator of biologically active points and display are connected to register. The second inputs-outputs of microcontroller are connected with interface converter for connection with computer. Device allows use of any known techniques of diagnosis and ensures a wide variation of cyclograms of action on biologically active points in measurement of their parameters, and also computations of integrated value of resistance of biologically active points, and selection of optimal time of measurement with respect to testing signal front. EFFECT: increased accuracy of diagnoses. 1 cl, 1 dwg
