METHOD AND DEVICE FOR MEASUREMENT OF ELECTRIC PARAMETERS OF DERMATIC AND MUCOSAL INTEGUMENTS Russian patent published in 2002 - IPC

FIELD: medicine and medical equipment, applicable for estimation of the condition of a biological object according to the electrophysical parameters of its integuments. SUBSTANCE: the method consists in installation of electrodes on the object of measurement testing the action on the object of measurement, as well as in measurement and estimation of the nature of variation of voltage across the electrodes during the testing action. The testing action is accomplished by successive transmission of pulses of current stable in amplitude of the negative and positive polarities respectively. The duration of transmission of a current pulse of the positive polarity exceeds the duration of transmission of a current pulse of he negative polarity at least by one and a half times. The valve of amplitude of the current of the negative polarity exceeds the value of amplitude of the current of the positive polarity at least by one and a half times. The device for measurement of electric parameters of dermatic and mucosal integuments has a basic and measuring electrodes, generators for shaping of current pulses of the negative and positive polarities respectively, synchronizer, measuring amplifier, unit for estimation of the parameters of the measurement object, and a unit for gathering and processing of information. EFFECT: reduced exciting action of the testing current on the nervous and muscular tissues of the object of measurement at simultaneous intactness of the functional condition of the object of measurement. 24 cl, 9 dwg
