The proposed device relates to the field of medicine and can be used both in functional diagnostics and in mass (preventive) examinations of the population. The last of these applications is most relevant at present, since domestic health care is faced with the task of universal medical examination for the purpose of early diagnosis of possible diseases.

The aim of the invention is to improve the quality of diagnosis by making it possible to determine the degree of pathology of the affected organ.

The invention is illustrated in the drawing, which shows a functional diagram of the device.

The device consists of a signal generator of variable polarity 1. Contact electrode 2, search electrode 3, amplifier 4, detectors 5 and b, voltage divider 7, first comparison circuit 8, measuring element 9, first shaper 10, decoder 11, block settings 12, second. - the fifth comparison circuit 13-16, the first to fourth memory elements, display unit 21, power supply 22 and second driver 23.

The device operates as follows.

When you turn on the power source 22 (or press the Reset button), the second driver 23 generates a pulse that prepares the device for the measurement cycle, namely: sets the memory elements 17-20 to the zero state and provides the discharge of the capacitors of the detectors 5 and 6. Generator 1 starts to generate pulses (positive and negative) of the same duration and the same amplitude (in absolute value). A pulse frequency of 20-200 Hz can be set using a generator switch. The amplitude of the pulses does not exceed two volts, which, when the electrodes are short-circuited (R heat, equivalent to 0), creates a current in the measurement circuit of not more than 20 µA. The electrode 2 is connected to the patient’s hand using a special clamp, it is a contact electrode, and electrode 3 is a search electrode. The signal of variable polarity through the search electrode 3 is fed to the input of the amplifier 4, with a gain of the order of. From the output of amplifier 4, the signal is fed to detectors 5 and 6, where the maximum values of the positive and negative signals, respectively, are stored, then they follow the voltage divider 7. From the output of the detector

6, the signal is simultaneously supplied to the comparison circuit 8, at the output of which a signal appears when the resistance of the acupuncture point to the negative current is less than a fixed value. The signal from the comparison circuit 8 is fed to the input of the first driver 10, the signal of which gates the memory elements 17-20. From the output of the voltage divider 7, a signal proportional

the minimum value of the positive signal; Ui is the maximum value of the negative signal, (or the ratio of resistances5), goes to the measuring element 9, which is an analog-to-digital converter, and then to the decoder 11, the outputs of which are connected to the corresponding inputs of the comparison circuits

0 13-16.

The combination of elements 13-16 and 12 makes it possible to isolate a signal corresponding to the ratio of the electrical resistances of the patient’s skin to a current of variable polarity at the point of application of the search electrode. In this case, four gradations of the signal are distinguished, which correspond to the following degrees of organ damage:

The signals from the circuits 13-16 are supplied to the elements 17-20, the reset of which is carried out from the shaper 23. Information is recorded in the memory elements by the signal co. circuit 10. When one of the circuits 13-16 and 17-20 is triggered, the corresponding indicator element 21 is displayed. For repeated measurement in

the test point, press the Reset button and the measurement cycle will be repeated.

Examples of specific performance: a generator of signals of variable polarity can be implemented according to one of the schemes indicated in the monograph of V.S. Gutnikov

L., Energoatomizdat, 1988, p. 109; amplitude detectors 5 and 6 can be implemented according to the circuits indicated on p. 121 of the same monograph, or see A.G. Alekseenko, E.A. Kolombet, and G.I. Starokov, Application of precision analog microcircuits, M., Radio and Communications, 1985, p. 198; element 9 can be performed according to the scheme in the monograph of V.A.Shilo Popular digital microcircuits, Directory, M., Radio and communications, 1988, p. 219, the implementation of schemes 17-20 see described in the monograph V.A.Shilo, p. 229. The remaining elements of the device can also be made by known technical means.

Thus, the inventive device allows revealing the affected organ and assessing the severity of the pathology, moreover, the introduction of criteria for assessing the degree of the affected organ by the ratio of the parameters of the electroanomal point to the positive and negative currents allows this diagnosis to be carried out with great accuracy.
