Patent RU 2137457 describes a method for determining the state of an organism, by which the electrical conductivity of 24 points of twelve symmetric meridians is measured, and then the obtained data are processed. Put the obtained values on the scales of the graph table. Pre-scale applied to the right and left sides of each column of the table. Connect the values to each other, obtaining a "diagnostic line". In the "physiological corridor" distinguish the center line. The state of the meridians is determined by the location of the "diagnostic line" relative to the boundaries of the "physiological corridor" and its center line. The device and the method it implements allow for the rapid diagnosis of the state of the body.

The patent RU 2268643 discloses a method and device for medical information-measuring diagnostics.

The measuring and additional electrodes are made in the form of a coaxial pair with a given size and arrangement of the electrodes. The device can be used in specialized diagnostic devices for medical institutions based on the methods of electro-puncture. 3 ill.

However, all currently available means for determining the conductivity of the skin are complex and require special training to interpret the measurement results, are not adapted for use by non-specialists and do not give specific recommendations for contacting a doctor of a certain specialization, thereby preventing the possibility of self-medication.

Closest to the present utility model is the device according to patent RU 2146877, which contains a measuring, additional and two indifferent electrodes, two differential amplifiers, a current-voltage converter, a voltage source and a recorder.

The measuring and additional electrodes are made in the form of a coaxial pair with a given size and arrangement of the electrodes. The device can be used in specialized diagnostic devices for medical institutions based on the methods of electro-puncture.

As is obvious, the known device can be used only by a specialist or, in any case, by a well-trained user, and only for special purposes. The device provides information about the occurring pathological changes, but does not allow providing the user with simple and practical recommendations for contacting the appropriate specialist. This is especially important for people of advanced age who are not related to medicine.

The known device, as well as all of the above, is not adapted for ordinary users and does not exclude the process of self-medication.

The device 1 for monitoring the state of health includes an active 4 and passive 3 electrodes, an audio connector 12 and a control unit 2. Active 4 and a passive 3 electrodes and an audio connector 12 are connected to the control unit 2. Connection is made using a standard push-button connector. The active electrode 4 is made in the form of a tip (or fingertip), in which the inner part is made of electrical insulating material, and the outer part is made of conductive. Passive electrode 3 is made disposable, adhesive.

The control unit 2 includes an input voltage converter 7 for converting the alternating voltage received from the headphones of the audio jack 12 to a constant stabilized voltage. The measuring circuit 11 is also part of the control unit 2 and contains a ballast resistance 9 for limiting the current of the measuring circuit 11, connected on the one hand to the active electrode 4, and on the other hand, to the input voltage converter 7, and a reference resistance 10, the voltage drop on which in proportion to skin conduction. The reference resistance 10 is connected, on the one hand, to the passive electrode 3, and, on the other hand, to the 7.8 converters. The output voltage converter 8 in the control unit 2 is used to convert the voltage drop at the reference impedance 10 into a pulse-width modulated output signal, the duty cycle of which is proportional to the measured skin conductivity transmitted through channel 6 of the microphone of the audio jack 12 and the audio jack 13 of the mobile device to a mobile device (not shown) for subsequent analysis in accordance with the program for assessing the state of health and issuing recommendations for contacting specialists in the mobile device. The device 1 is configured to transmit a pulse-width modulated signal to a mobile device, which is a tablet or smartphone equipped with a device for connecting an audio headset. It is possible to make a device with an input voltage converter, including an internal power source for additional power.

In addition, it is possible to place the input and output voltage converters and the ballast and reference resistances in the housing of the mobile device.

Device 1 operates as follows. The input voltage converter receives an alternating voltage from channel 5 of the headphones of the audio jack 12, converts it to a constant voltage and stabilizes at 5 V.

A stabilized constant voltage is supplied to the measuring circuit 11. To limit the current in the measuring circuit 11, the ballast resistance 9 included in it is used so that the current in the circuit does not exceed the values allowed by the electrical safety conditions. In this case, it is 35-40 μA.

When the passive 4 and active 3 electrodes are pressed against the skin of the user at a point on the acupuncture meridian, the measuring circuit 11 is closed. A current flows through the reference resistance 10. The voltage drop at this resistance 10 is directly proportional to the current in the measuring circuit 11.

The voltage drop is converted in the converter 8 of the output voltage to the output alternating voltage and is modulated by pulse-width modulation, the duty cycle of the modulated signal is directly proportional to this voltage.

It is also possible to sample the output signal in the format: the minimum amplitude is 0, the maximum amplitude is 1.

The output voltage is transmitted through channel 6 of the microphone audio jack 12 to the mobile device. This voltage is analyzed by the software of the mobile device. The voltage ratio is converted to numerical values directly proportional to the current in the measuring circuit in the range from 1 to 200 conventional units.

Management of the measurement process and visualization of the results of monitoring the state of health is carried out by software installed on a mobile device. The software uses tables of dependencies between the values of the measured skin conductivity and human health. Such tables were obtained by the author using the improved Nakatani method and are given in the description of the method for monitoring the functional state of the patient’s body in the application for invention 2013147830, which is fully incorporated by reference.
