Mechanisms of impact and therapeutic effect of application electoophunctures Described in detail in special literature. In this method, I am attracted to the moment that biologically active points It is made of soft non-volatile effect without disturbing skin. Small currents up to 100 microampers do not even injure intercellular membranes in the body, having influence on the Bat akin to the point massage.
Therefore, using such an appliance at home, it is difficult to harm. Using simple sets of points from Atlas on point massage and directories on Eastern Reflexotherapy, you can get good results for the treatment of certain diseases, to remove pain syndromes. Effectively treatment of Lyumbago and Ishias (tested on its own experience), with joints in the joints. Of course, the treatment of chronic diseases at home without medical education is unrealistic, but help himself and relatives in some situations are quite possible.
The design of the device is a plastic case with a working panel, on which the measuring head of the microamermeter and control knob is located. One of the connectors of the device is connected to the copper electrode (which is convenient to hold in hand), the other connector is connected to the movable electrode-shchu, which is a plastic handle with a silver-plastic electrode with a diameter of about 3mm, which is placed on the BAT. The device is powered by a 9 volt type "Crohn" battery. 
The search for biologically active points is carried out by the atlas, after some time the skill and knowledge of the main points are purchased.
Cocking the probe to each other, the "current" knob is set short circuit About 80 microampers. Then the copper electrode is taken into hand, the opposite side of the Bat, the movable electrode is put on a point with a small pressure. The current in the biologically active point is almost independent of the state of the skin, and the main depends on the state of the meridian, its ability to pass energy, from the purity and health of the body. In the first few seconds after installing the movable electrode, the device shows a slight current (1-10mk), no sensations. 
Upon interest, some time begins a pleasant (or painful) pinching, and the appliance arrow begins to rise to about 60 μA. It is necessary to hold a few seconds before fixing the values, then "pump" the point with the help of cakes. To do this, click the "Revolution" button and keep it, observing the reaction of the point to the polarity shift. She makes a little fast release, then, thinking a little, begins to reduce the current to very small values. Having waited for lowering the arrow, let go of the button and wait for the current increase to 60 μA.
Thus, "pump" a biologically active point. During data of manipulations, there may be some pain syndromes at the point, with severe pain you just need to reduce the current. As a rule, the most painful points are the points that are responsible for the patient.
The above-described current behavior in BAT during warming and cakes takes place when "healthy" point. If there are deviations from the norm, the arrow behaves differently. The point can not "break through" for a very long time, that is, not to go to the current passage of 60 μA, and the reaction to the replacement of polarity can be different. This indicates a deviation in a state of BAT, therefore, it is necessary to effectively impact it.
The usual tester for the electroplating, the so-called ledneva-Usachevapublished in the magazine "FIS" is presented in Scheme 1. The scheme is so simple that does not require description. The current is regulated by a variable resistor, an additional resistor is required to prevent accidental short circuit when setting current. The button is reversed. The device is conveniently used from the "Crown" type battery -9 volt, it is small in size and enough for a long time. 
For more efficient "penetration" of the point of exposure, the diagram of the device with a short-term increase in the applied voltage is applied. When you click on the "TRAPER" button, a tripled battery voltage is applied to the BAT. For an effective "breakdown", the BAT press the button several times shortly by following the arrow behavior. With an increase in the current and the appearance of the discharge, let go of the button and then carry out the regular warp. The instrument diagram for the electroplating with the "breakdown" function is given in Scheme 2.
In this scheme, an increase in the applied voltage is carried out due to the sequential connection of pre-charged containers. When the "TRAPH" button is released, the tank is charged to the battery voltage, when pressing the button, they are turned on sequentially. To limit the current with an enlarged voltage, another additional resistor is applied.
When working with BAT often, it is necessary to analyze the state of "unpassed" points or pre-find "excited" BAT. So, the points responsible for certain internal organs, when symptoms of the disease, this organ appears, have reduced electrical resistance, and can be detected using a special search block. This is caused by the need for primary BAT diagnosity and is applied in practice. For these purposes, the following instrument diagram (Scheme 3) is made with a search block on transistors, which gives an indication of a point of a point in the luminescence of the signal LED and on the audible signal. The response current of the signal is graduated according to the knowingly "healthy" point, then a search for "excited" BAT. In many cases, it gives the effect of the use of searching with reverse polarity. To do this, the instrument provides a fixed polarity switch. In the rest of the diagram of the device and work with it is the same. 
Such an appliance is already enough to effectively influence biologically active points, "treating" them.
The effect on the BAT can be tonic and sedative. In Eastern Reflexotherapy (acupuncture), this is achieved by various types of needles and exposure time. In the electropuncture, the achievement of a tonic or sedative effect is achieved by the use of impulse exposure. Research revealed, what frequencies and polarity of the impact impulses and for how time this or that effect is produced. Therefore, for efficient operation, the pulse generator was added to the device. To control the generator, the frequency switch and the pulse type switch are used.
And so that the device becomes completely professional, a block of electrical diagnostic diagnostics is added to it. This requires a 12 volt battery, time shutter speed (3-4 sec) and current meter up to 200 microamper. 
The diagram of such a device is shown in Figure 4.
Having such a device, any attending physician, a practicing electrophuncture, will be able to diagnose and make the necessary treatment. Methods of data processing, analysis of the state of meridians, the purpose of exposure points and modes, is a separate and very large topic. 
In the presence of components, this can be done by software methods, which gives acceleration of data processing. This is already the topic of big medicine and scientific dissertations.
For the unlimited correction of the body's condition, methods of stimulation of biologically active points (BAT), acupuncture points are widely used. Certain difficulties, especially on early stages The use of this method causes the process of properly determining the location of the BAT on the body.
To date, there are many devices and methods of diagnosing BAT. Controlling the properties of these points, in particular, resistance to DC, one can follow the change in the state of the internal organs, to determine the effectiveness of the reception of drugs and conducting therapeutic procedures, as well as optimize them. It is possible to observe the dynamics of disease and recovery with a quantitative assessment of the degree of deviation from a normal state, return rates to the state of the norm.
One of the most reliable and visual methods of diagnosing the pathology of the internal organs is the method of R. Fall and its modifications.
In accordance with this method, it is assumed that when measuring the electrical resistance of a certain battery, it is possible on indirect data (change of electrical resistance) to monitor the change in the state of these organs. Each vital body corresponds to "its" set of BAT.
It is believed that with the "normal" state of the body electrical resistance Between points of acupuncture (BAT) and the common electrode must be in some permissible limits. The greater the value of the electrical resistance of the controlled point responsible for the state of a certain organ, differs from the permissible value, the more expressed the pathological process. For example, resistance exceeding the norm corresponds to the development of degradation processes, aging, the extinction of the vital functions of the body, lowering its tone. Reduced resistance Inappropriate the development of inflammatory processes related to the acute period of the disease. The permissible values \u200b\u200bof the resistance of the controlled point for each particular person are purely individual and are determined by its constitution (physique), as well as tissue electrical conductivity.
With the help of a certain experience described below, you can diagnose the state of people, follow the changes in the state of the internal organs during the disease at the quantitative level, and also to correct it in a timely manner, controlling the correctness of the choice of the drug, choose from the list of various medicines the most effective for a particular patient .
In fig. 24.1 shows a diagram of a device with an arrow indicator for the diagnosis of BAT [RL 11 / 97-30]. The device is performed on the K1222A (K118UD1A) chip. The internal filling of this chip (amplifier) \u200b\u200bis presented in Fig. 24.2. The scheme comparison (Fig. 24.1 and 24.2) shows how to simplify the installation of the device, if it is not made from separately taken elements, and on the basis of a chip containing ready-made nodes and elements of a more complex circuit.
At the inlet of the differential amplifier (chip) included a double T-shaped resistive bridge. R1 + R2 and R3 + R4 resistor chains with an open measuring circuit Determine the diagram balancing (using R2 arrow measuring device Install on zero). The value of the maximum current (50 ... 100 μA) through the measuring instrument frame limits the resistor R6, and through the measuring chain - the R5 resistor.
Fig. 24.2. Analog of chip K122AUD1
For a diagnostic device (Fig. 24.1), the maximum voltage drop at the measurement object is about 2 at the current through the measuring circuit of no more than 10 μA. This device It can also be applied to measure electrical and non-electrical values \u200b\u200busing appropriate sensors (resistance, voltage, temperature, humidity, light flux intensity, etc.).
The controlled circuit is connected to the input clips of the device using a common and search electrode. The overall electrode is made in the form of a stainless steel cylinder or a diameter of 15 mm and a length of 60 mm and is clamped into the palm of diagnosed. The search electrode from the wire with a radius of the rounding of 0.3 ... 0.4 mm is made of stainless steel, and they relate to the dosage pressure of the controlled BAT. Measurement of resistance of each of the BAT must be carried out at least three times. All scales are accepted for 100%.
In fig. 24.3 shows a typical view of the measurement chart of 12-class "energy channels" (meridians) marked with Roman numbers. They correspond to various internal organs: light, thick intestines, stomach, spleen and pancreas, heart, thin intestines, urinary bubble (urinary system), kidney, pericarde
(vascular system), "Triple Heater (Endocrine System), Gall Bubble, Liver. The specific location of the BAT associated with certain organs can be determined by special literature. In addition, if there is a pronounced disease, "Points-Herack" can be found on their own, experimental.
To control the change of the state of the BAT (health status) of a small group of people, it is enough to systematically enter the results of measurements according to controlled channels on the schedule (electrical resistance - channel - date), fig. 24.3. The output of the measured value for the permissible limits indicates the development or availability of the disease.
A device intended for simultaneous search and stimulation of BAT consists of a pulse generator and power amplifier (Fig. 24.4) [RL 9 / 91-7]. The pulse generator contains an adjustable time-loading RC chain (R3 and C4). In parallel, the C4 RC chain condenser is connected to the multivibrator on the VT1 and VT2 transistors (CT315). These transistors operate in inversely inclusion (with a different polarity of the supply voltage). Database databases are not associated with other elements of the circuit. The multivibrator is loaded on the R4 resistor. C1 - SZ condensers, C5 provide positive feedback; Parallel to the C1 condenser connected search electrodes. The signal from the multivibrator enters the power amplifier on the VT3 transistor and is converted to the sound. electrodynamic head (telephone capsushuel BF1).
If the measurement object is missing (search electrodes open), the multivibrator generation frequency is in the ultrasonic region. When the search electrode is connected to the human body and the subsequent search for the BAT chain of the multivibrator's positive feedback through C1 - SZ capacitors is closed. At the same time, the generation frequency is sharply reduced due to the significant differences from the usual (typical) resistance values \u200b\u200band the skin capacitance in the vicinity of the BAT. This allows you to confidently detect biologically active points.
If it is necessary to expand the capabilities of the device (to ensure an effect on acupuncture points) instead of the telephone caps, includes a consistent (enhancement) transformer, and the electrodes of active impact are attached to its conclusions. A positive feedback circuit (search engine electrodes) is shuffled by a multivibrator generated by the signal amplifier on the VT3 transistor. The generation frequency varies with a change in resistance R3. The amplitude of the signal can be adjusted by turning on the R4 resistor in the potentiometer. The potentiometer engine is connected to the VT3 transistor base,
The device can also be used as a universal probe. electrical chains, To study the dynamics of processes occurring in living organisms, creating a combined measuring system "device - person", as a generator of pulses to adjust radio-electronic equipment, etc.
The device for searching or stimulating the BAT (Fig. 24.5) is the simplest ohmmeter [Device "Lady", Latvia]. Sequentially with the power source included the Arrow Device of the Republic of Armenia and the current-limiting resistors R2 and R3. At the same time, the device described can be used to influence BAT by controlling current strength. To change the polarity of the voltage supplied to the electrodes, the SA1 switch is designed.
Electroakapuncture stimulator with an ohmmeter (Fig. 24.6), proposed by M. Tsakov and modernized by V. Kozlov, was performed on the K561L5 CMO-chip and the transistor venerator VT1 [RL 10 / 92-24]. With the help of the SZ condenser and the VD4 diode, pulses are formed, whose amplitude is close to double power voltage. Translate the device from the BAT search mode to the stimulation mode allows the SA1 switch. In the ONMETER search mode on the VT1 and VT2 transistors (amplifier direct current) Connect to the studied portion of the body. When touching the BAT electrode, the HL1 LED lights up.

A little story. In amateur practice, sometimes there is a need to do things, unexpected even for themselves. So, for example, at the request of one friend from the rolling circles, at the time there is an urgent need to make a real-working device for a visual demonstration of some features of human body electrical conductivity. To make sure in the real existence of the so-called "acupuncture points" by methods that would be "scientific" or, at least close to them :-) Well, to convince others, inclined to doubt ...
This necessity happened, as far as I remember, in the late 80s of the last century, when the Internet accessibility was at all and simple mortals had to believe on the word of different kind of "shamans" from China (or Kyrgyzstan?), Which seem to know what Places can and need to stick needles, and it was all called the fashionable word "acupuncture".
The nearby place of secret knowledge at that time was the republican library of Dushanbe, where it was possible to take annual footers of the Radio magazine, and already in them - to search for the desired schemes. Schemes were found, soldered and tested on neighbors-volunteers and showed quite positive results. In the sense that acupuncture points really had a place to be quite easily and defined. Separately, it should be noted that as a result of experiments and tests, no-volunteer suffered :-))
Indications and contraindications
Next will be described one of the very simple schemes The electrostimulator, which allows you to search for biologically active points on the human body (Shiatsu or Zhen-Tszy therapy) and, moreover, automatically produce their stimulation with a weak current, which may have the same effect as the unsolicited acupuncture procedure. However, the device was assembled as an experimental sample and the presence of either the absence of therapeutic or other effect, of course, is not guaranteed. Perhaps the method can be successfully used to prevent and treat many diseases at home, but after consulting with a qualified physician and all its recommendations.
The work of the stimulator is based on the effect that in a place where the active point is located close to the surface of the skin, the resistance of the human body decreases sharply. This can be easily checked even by the usual tester included on the measurement of maximum resistance (2 MΩ and more), if one probe is kept in hand, and others touch different parts of the body. The resistance of different sections will be quite noticeable to vary.
The scheme is extremely simple and is a simple pulse generator, the frequency of which is determined by the RC chain. Here, as R acts resistance at this particular point of the human body. Since resistance at different points is different, then the generation frequency will also differ significantly. The frequency will be the higher the less skin resistance. Therefore, the procedure for finding a biologically active point (BAT) is to find a point area of \u200b\u200bthe skin, where the frequency of flashing LEDs and the sound of the dump emitter will become the highest. In this case, one of the electrodes is a metal plate or foil on the instrument housing (or the device body itself, if it is metallic), which are in contact with one hand, and the second is a metal pin, with the help of moving the skin and is searched for BAT. Power can be from any batteries or batteries with a voltage of 4.5 to 12 V.
The pulse generator is assembled on the chip, it can be a digital MS type K561L7, which contains 4 elements and not in one case. Others, for example, K561L9, can also be applied, where 2 elements and non, but with three inputs (the power of the generated pulses with such a microcircuit will even increase), or other, similar MS series 561, 174, 164, 155 or imported. But it should take into account the possibility of another decay of the conclusions and the supply voltage range of the chip. It is also suitable MS with elements or not.
The diode bridge forms the impulses of a certain polarity. Its diodes can be any low-power, such as KD520, 521, 522, etc., the LED indicator is also of any, the brightness of its glow can be adjusted to the VR1 stroke resistor (it cannot be reduced to zero resistance, otherwise the LED can burn!). So it's better to choose permanent resistor The necessary nominal. Punitioner can be installed, you can not put (I did not put). He does not affect normal work The device is only needed for sound indication of the device, if necessary. It can be types of ZP-1, ZP-2, ZP-4, ZP-5. The device does not require any adjustment - feed the power and, if all items are working, it immediately starts working.

Methods of use
IN initial stateWhen the resistance between the electrodes is large, the generator does not generate anything. The LED can burn constantly, or do not burn at all. When touching probe, generation begins. The LED begins to flash, the more often the smaller the resistance between the senses and, consequently, is closer the biologically active point. If you get directly to the point of the BAT, the LED flashes with the maximum frequency. When using a sound emitter in the scheme, the sound also reaches the maximum frequency. When holding the probe to BAT, its stimulation occurs pulse current. In special literature and other sources there are recommendations that impulses of what polarity are better to influence BAT and, as a rule, it is recommended to influence negative impulses. At the same time, the second, the positive electrode should be kept in hand, or apply to another place (this should be obtained from the doctor). But you can add a switch to the device for convenience and with it to change the polarity of impact pulses.
You can collect the device in any suitable plastic or metal case. If the housing is metallic, then one of the electrodes should be connected to the housing. If the case is made of dielectric, then the metal plate or foil is glued to it, connected to one of the electrodes:
In many different sources, including on the Internet, you can find maps of the location of biologically active points on the human body, however, the exact position of each point for different people may differ, but it can be defined accurately using the proposed device. Below are the example of several drawings of such cards:

Electropuncture Reflexology Devices
Properties of the skin as a regulator of various physiological functions of the body are known for a very long time. Various migrations, massages, baths, banks are successfully used to treat various diseases since ancient times. At the same time it was noted that the reactions of the body depending on the place of exposure may be different due to the features nervous system man. Such reactions underlie reflexology using the impact on certain points on the surface of the skin in order to regulate the functions of various organs, which allows you to take pain, improve cardiac activity, to remove cramps, etc. The impact on these points in Chinese medicine was carried out with the help of gold or silver needles or cacling with special cigars from hide grass. Currently, the magnetic field, laser radiation and electric Toki.. In the latter case, the impact is called electropuncture. According to the ideas of Chinese doctors, in cases where there is a violation of one of the internal organs, some points on the skin become sensitive and even painful until the recovery has come. These points are sufficiently small - no more than 2 mm in diameter and only an experienced doctor forces to find them and, using the Atlas of the arrangement of the active points of the person's skin, make a diagnosis. Most often, such points have anomalous constant current resistance in relation to neighboring sites. Already inXX Century, scientists have proven that therapeutic effects on the body can be carried out not only through certain points, but also affecting certain, sufficiently large zones with a diameter of several centimeters. Using the traditional diagnosis of the disease, you can not find points, but to influence certain zones, knowing the "binding" of patients to these places. Since skin resistance is highly dependent on the state of the horn layer covering the epidermis, the current of exposure to the biologically active point or the zone is very unstable and depends on many external and internal factors. If the point is not anomalous low resistanceThe impact can be carried out only after the breakdown of the upper horny layer of the skin. For this, it is enough to press to the point or zone a negative electrode with a tangent surface of about 1 mm2 (a positive electrode in the form of a fairly large metal object is clamped in the nearest to the point or zone of hand) with a voltage of about 18 V. After about 3 -5 seconds, there will be a trigger of the horn layer And the current sharply increases to the painful threshold. The current via the point should be within 10 ... 100 μA and be quite stable, despite the polarization effect, which is expressed in a gradual increase in the resistance of the point when DC flowing. Electropuncture enthusiasts are most often used devices collected according to the diagram shown in the first drawing. The scheme is very simple and accessible in repetition, but has drawbacks, very felt by patients. When using the device, the resistance of the variable resistor is installed on the "zero" so that the potential difference at the touch point of the probe has not decreased due to the resistance of the skin. Current is controlled by the miniature directional indicator from the old tape recorder. After about 5 seconds, the trigger of the horn layer and the current increases sharply to 250 μs, which causes a rather tangible painful effect, the point burn may even appear in the electrode touch site. As soon as this event occurs, a variable resistor establishes a painless current of about 50 μA and continue the procedure for several minutes. Since skin resistance is continuously changing, it is necessary to periodically adjust this current.
The author of the site was developed by several electrical appliance devices, in which the exposure current was automatically limited to a predetermined value and remained stable for the entire procedure. In addition, for a more effective impact on individual active points, some devices had the effects of exposure to variable or pulsing currents of various frequency and duty. Unfortunately, for years, the author's archive is largely lost, but the descriptions of several devices have been preserved and are presented below. 
The scheme presented is modernization above the current to stabilize the current through the probe, which makes it possible to significantly reduce the fluctuations of the current of the effect on biologically active points due to the polarization effects. The scheme uses controlled stabilongTL431 A, which allows simple means to stabilize the output current. To quickly install the output current, it is recommended to produce a graduation of the variable resistor and apply the current values \u200b\u200bright under the adjusting handle. If, by the condition of exposure to the BAT, the effect of a positive current is required, then the scheme can be supplemented with a two-pole switch connected to the output of the device. Both circuits require supply voltage at least 18 V, otherwise the point of the point may not occur. In the following scheme, the power of the device is carried out from four "finger" elements of AA or one 6F22 (Krone battery). To increase the voltage, the MC34063A chip (MC33063A) is used. As a coil L1, you can use any suitable wound on the ferrite rod core with brushes, which are often used in pulse transducers. For independent manufacture on a suitable core F.
3 mm, M2000NMs are wound up about 100 turns of the wire PEV-2 0.1 ... 0.15. Instead of used in the Diode diagram, VD1 can use any speed diodes with a voltage of at least 100 V. In order to save the capacity of the batteries in the diagram there are no LEDs, so the consumed of the current of the device does not exceed 5 mA
With long-term electropuncture effects, it is recommended to periodically change the polarity of the output current. To determine the points of impact, the Atlas BAT, which can be found on the Internet. The use of such devices should be carried out by a prepared doctor who knows the location of the internal organs of the human body on the human body and can deliver the correct diagnosis to the patient to stimulate only certain active points.
