(54) DEVICE FOR RESEARCH OF ELECTROCAL CONDUCTIVITY

I

The invention relates to Medigsh technique, namely, devices for monitoring and displaying diagnostic information.

A device for the investigation of efect permeability, comprising measuring electrodes, a memory circuit, a divider and an indicator device 1.

However, the known device does not provide continuous monitoring of conductivity in anomalous areas of the body, which reduces the accuracy of the readings taken.

The circuit of the invention is the uninterrupted control of conductivity in abnormal areas of the body.

This goal is achieved by the fact that a device for studying electric conductance, comprising measuring electrodes, a memory circuit, a divider and an indicator device, is equipped with series matching circuits, a comparator and a digital display unit, the memory circuit connected in series with the divider and indicator device connected to the first input of the comparator directly and through the matching circuit with the measuring electrodes, and the second input of the comparator is connected to the second output; l.

The drawing shows a block diagram of a device for the study of electroconductivity.

The device contains measuring

10 electrodes 1, a memory circuit 2, a divider 3, an indicator device 4, a serially connected matching circuit 5, a comparator 6 and a digital display unit 7, the memory circuit 2 being connected in series with the divider 3 and the indicating instrument 4, to the first input of the comparator 6 directly and through the matching circuit 5 with the measuring electrodes 1, and the second input of the com20 of the parator 6 is connected to the second output of the divider 3.

The device works as follows.

The input signal is taken by the measuring electrodes 1 and is fed to a matching circuit 5, where it is converted to the kind required for. operation of the memory circuit 2 and the comparator 6. A signal from the output of the matching circuit 5 is fed to the input of the memory circuit 2, where it passes mathematical processing and memorizes its maximum value. From the output of circuit 2, the signal is fed to divider 3 where the signal is matched with the load, which is the indicator device 4, and is converted into a value that is the trigger threshold of the comparator 6, and to which is fed from the second output of the divider 3. At the same time, the first input of the comparator 6 is fed the signal from the matching circuit 5 and its signal is compared with the signal of the divider 3. Relatively compared to the output of the comparator 6 is fed to the digital display unit 7.

Example. Patient G., 48 years old, diagnosis: selveoloneuritis of the trigeminal nerve in the area of the extracted 8 tooth Using the proposed device, we searched and measured acupuncture points located on the left earlobe, which correspond to the projection of the lower jaw organs on the left. You have two points with a maximum conductivity of 180 and 175 relative units. on the device with a stable search current of 10 μA. Acupuncture needles were inserted at these points using the TopMO3Hotviy method. After 10 minutes, the pains cease.

The proposed device has been applied to 25 patients for neuralgia of the facial nerve, it has been found that the proposed device provides uninterrupted control of conductivity in abnormal areas of the body, and speeds up the process of determining conductivity, improves the accuracy and reliability of diagnostic information.
