Description
Изобретение относитс к медицинской технике, а именно к способам измерени электрического сопротивлени биообъекта.The invention relates to medical technology, in particular to methods for measuring the electrical resistance of a bioobject.
Целью изобретени вл етс повышение точности измерени сопротивлени .The aim of the invention is to improve the accuracy of resistance measurement.
Процедура измерени сопротивлени биообъекта состоит из двух этапов.The procedure for measuring the resistance of a bioobject consists of two stages.
На первом этапе производ т измерение сопротивлени биообъекта с помощью двух электродов, имеющих структуру, например, в виде изолированных провод щих чеек. На первом этапе электрически соедин ют часть чеек, расположенных, например, в шахматном пор дке.At the first stage, the resistance of a bioobject is measured using two electrodes having a structure, for example, in the form of insulated conductive cells. At the first stage, a part of cells located, for example, in staggered order, is electrically connected.
На втором этапе количество электрически соединенных чеек увеличивают в К раз, причем внешние габариты электродов в обоих случа х сохран ют одинаковыми. Измерительный ток также увеличивают в К раз и производ т измерение сопротивлени биообъекта .In the second stage, the number of electrically connected cells is increased by a factor of K, the external dimensions of the electrodes being the same in both cases. The measuring current is also increased by a factor of K, and the resistance of the bio-object is measured.
Услови измерени сопротивлени в обоих случа х позвол ют поддержать плотность тока через переходные сопротивлени неизменной , в то врем как плотность тока через внутренние ткани измен етс в К раз.The resistance measurement conditions in both cases allow the current density through the transient resistance to be kept constant, while the current density through the internal tissues changes by a factor of K.
Таким образом, в обоих случа х измерени падение напр жени на переходных сопротивлени х поддерживаетс неизменным, а падение напр жени на внутренних ткан х измен етс в К раз. Тогда сопротивление внутренних тканей Rrp определ етс по формулеThus, in both cases of measurement, the voltage drop across the transient resistance is kept constant, and the voltage drop across the internal tissues changes by a factor of K. Then the internal tissue resistance Rrp is determined by the formula
RR
- Ji-.Si , K-i- Ji-.Si, K-i
а переходное сопротивление Rg определ етс по формулеand the transition resistance Rg is determined by the formula
Rj и R,j - межэлектродные сопротивлени , измеренные на первом и втором этапах соответственно. Rj and R, j are the interelectrode resistances measured in the first and second stages, respectively.
