DEVICE FOR MEASUREMENT OF ELECTRICAL RESISTANCE OF ALIVE SKIN Russian patent published in 1999 - IPC

FIELD: medicine for determination, measurement and registration for the diagnostic purpose. SUBSTANCE: the device comprises a measuring transducer connected to the input of a source of electric oscillations. The source is made as an oscillator of several frequencies within 10⁴ to 10⁶ Hz. The source also produces a signal containing information on the value of tissue electrical resistance. The radio-frequency signal from the source output is applied to the input of a non-linear converter, the non-linear signal converter converts it to a low-frequency signal. The device for processing of the registered signal separates the component and amplifies it. The level of voltage at the device output is registered after actuation of the measurement current indicator. EFFECT: enhanced truth of measurement results due to provision of measurement of tissue impedance. 4 cl, 1 dwg
