Description

The invention relates to medical equipment and can be used in medicine for electropuncture diagnostics according to the method of Dr. R. Voll.

It is known [1] the device K + F-Universal-diatherapy unit containing active and passive electrodes connected to a measuring device, a power supply with a device that supports constant voltage. K + F-Universal-diaterapuncturer was first used by R. Voll for electropuncture diagnostics and therapy. R. Voll considered the "deviation of the arrow" as a diagnostic value, the unit of measurement was "division of the scale" (Ts, Teilskala). The scale numbered 100 divisions. F. Kramer notes that “it would be more expedient to switch to the standard unit of measurement in the natural sciences for graduation”. The lack of measurement capabilities in the process of electropuncture diagnostics of electric current strength, electrical resistance, electrical conductivity and voltage drop at a biologically active point is a disadvantage of the K + F-Universal-diatherapy unit.

In the works of the Center for Intelligent Medical Systems, the diagnostic value “arrow deviation” was called “measuring level”, and the unit of measurement “scale division” was replaced by a “conventional unit” (cu) (Samokhin A.V., Gotovskiy Yu.V. Electropuncture diagnostics and therapy according to the method of R. Voll. - M .: IMEDIS, 2000. - 512 p.). Taking into account the great achievements of Dr. R. Voll in the field of medicine and medical technology, it is more expedient to establish the unit of measurement of the “fol” (Fl, Ve) as the unit of measurement for the diagnostic value “measuring level”, defined as the measuring level of the biologically active point, causing the arrow to deviate diagnostic tool according to the method of Dr. R. Voll on one hundredth of the scale. The device for electro-puncture diagnostics according to the method of Dr. R. Voll may be called "folmetr".

The conditions for calibrating diagnostic devices according to the method of Dr. R. Voll are as follows: zero deflection of the load, that is, a short circuit of the electrodes, corresponds to a deflection of the arrow by 100 divisions, with an electrical resistance of the load of 100 kOhm, the deflection of the arrow should be 50 divisions.

It is known [2] a device for electropuncture diagnostics containing active and passive electrodes, a scaling unit, a measurement and indication unit (microammeter), a power source, one output of which is connected via a switch to the first input of the scaling unit, the second output of the source is connected to the input of the second scaling unit and to the input of the passive electrode, the internal resistance of the circuit (resistor), the input of which is connected to the output of the scaling unit, and the output through the measurement and display unit is connected to the input active electrode. Measurements of electrical physical quantities using this device are not made, which is a disadvantage of the device. The inventors complain about the lack of the ability to compare the results of the examination of patients in the case of using various diagnostic devices. This is due to the fact that many researchers produce electropuncture diagnostics by direct measurements of electrical physical quantities. So, for example, the results of measurements of electric skin conductivity are presented in units of electric current strength (RF patent No. 2088202, CL A 61 H 39/02, 08.27.1997).

The readings of measuring devices and dial indicators of devices, which are used for electropunctural diagnostics according to the method of Dr. R. Voll, are inversely proportional to the electrical resistance of the load. The dependence of the deflection of the arrow of the diagnostic tool on the electrical resistance of the load can be represented as:

V = a / (R + b),

hence,

R = (a / V) -b,

where V is the deviation of the arrow;

R is the electrical resistance;

a, b are the coefficients.

Under the above conditions for the calibration of diagnostic devices, the system of two linear equations with two unknowns has the form (a / 100) -b = 0,

(a / 50) -b = 10 ⁵ ,

whence a = 10 ⁷ , b = 10 ⁵ , therefore

R = 10 ⁵ ((100 / V) -1).

The basis of the invention is the task of improving the device for electropuncture diagnostics according to the method of Dr. R. Voll by using an active electrode, a constant current source, a microammeter, a resistor and a passive electrode connected in series, and the microammeter contains scales, one of which is a linear scale deflection of the arrow and has 100 divisions, the last of which corresponds to the maximum strength of the electric current, while the others are electric scales th resistance, electrical conductivity and electrical voltages that are calibrated with respect to the linear scale divisions deviation direction in the formulas:

R = 10 ⁵ ((100 / V) -1),

S = 10 ^-5 V / (100-V),

U = 10 ⁵ I ((100 / V) -1),

where R is the electrical resistance;

V is the deviation of the arrow;

ρ is the electrical conductivity;

u is the electrical voltage;

I is the strength of the electric current.

The essential features that characterize the invention are the presence of an active electrode, an electric current source, a microammeter containing additional scales, a resistor and a passive electrode connected in series.

The essential features and distinguishing features, such as scales, graduated in units of arrow deflection, electrical resistance, electrical conductivity and electrical voltage, give the invention new technical properties, which are revealed in the expansion of its functionality by measuring electrical physical quantities of electric current, electrical resistance , electrical conductivity and voltage drop at a biologically active point, simultaneous with and measuring the deviation of the arrow according to the method of Dr. R. Voll, which helps to increase the reliability of the results of electro-puncture diagnostics.

A diagram of the device and its scale are shown in the drawings.

Figure 1 marked: 1 - active electrode; 2 - source of direct electric current; 3 - microammeter; 4 - resistor; 5 - passive electrode.

The device for electropuncture diagnostics contains an active electrode 1, a constant current source 2, a microammeter 3 containing additional scales, a resistor 4 and a passive electrode 5. Resistor 4 is intended as a setpoint for the electrical resistance of the device. With an internal electrical resistance of the electrical circuit of the device of 100 kOhm, an external load of 100 kOhm causes the device to deviate to the middle of the linear scale, i.e. by 50 divisions.

The device is used according to the well-known method of electro-puncture diagnostics of Dr. R. Voll. The passive electrode 5 is placed in the palm of the patient or attached to the underfold fold in case of diagnosis of the animal. The active electrode 1 touch the center of the biologically active point. A diagnostic electric current flows in the formed electric circuit, as a result of which the needle of the microammeter is deflected. The deviation of the arrow and the measured electrical quantities are recorded by the position of the arrow on the corresponding scales of the device. Scales are shown schematically in FIG. 2. They are given for a device, the voltage of a constant current source of which is different 1.5 V, and the maximum electric current strength is 15 μA.

Figure 2 marked: Vl - scale deflection arrows; μA - scale of electric current strength; k Ω is the scale of electrical resistance; μS - scale of electrical conductivity; V is the voltage scale.

The deviation of the arrow is recorded on the Vl scale, which is linear in scale and has 100 divisions. Division 100 corresponds to the maximum electric current strength. At the same time, the electric current strength is recorded on a μA scale, electrical resistance is on a k Ω scale, electrical conductivity is on a μS scale, and the electric direction drop on a biologically active point is on a V. scale.
