The invention relates to the field of critical care medicine and can be used to restore breathing, compensation, acute respiratory failure, removing the pain in extreme situations.

It is known that artificial lung ventilation (ALV) of the victim recovers breath and compensates for its acute respiratory failure in the provision of medical, emergency and intensive care support. Currently, the IVL victims prehospital, during transportation and in the provision of ambulance by manual in portable respiratory devices, respirators, with mechanical, gas, electrical drive and works on the principle of injection of air into the lungs or oxygen. The use of such devices is not effective, is difficult because of the large overall size, energy - and labour-intensive indicators, especially for a long time, is extremely limited in the presence of maxillofacial injuries or wounds and prevents distraction lifeguard for the implementation of other emergency response actions.

It is known that according to the electromyograms, rogramme, ECG, blood be noticed negative impact on the entire human body bioelectrochemical muscles of the limbs and the lower half of the body is missing (Our dikes, 1974).

Known elektromehnicheskiy method of mechanical ventilation in acute respiratory failure of the victim in the form of stimulation of the phrenic nerves or muscles of the diaphragm (Zilber A.P., 1978) does not lead to adequate breathing and requires special search motor points that it is difficult and time-consuming, especially when resuscitation wounded. Known close to the technical nature of the counterpart, which is a "Method and device for stimulation of respiration" (Application for invention France N 2493154 by MCI And 63 N 1/36), in which stimulation of breathing are used, at least two pairs of electrodes placed on the patient's body at the level of the respiratory muscles (inspiratory or expiratory). In addition, each of the pairs of electrodes are powered by an alternating current from a separate generator, the frequency of these two currents of generators differs slightly. The drawbacks of such solutions are the need of the use of two pairs of electrodes and two generators (or two channels in one generator), which complicates the equipment and technology of mechanical ventilation increases the preparation time for carrying it out, but the main drawback is that the known solution is used primarily only for the purpose of rehabilitation of the patient.

Known to maintain adequate blood oxygen saturation of the tissues of the body 26 dogs when modeling the OS is Roy of hathipole by artificial lung ventilation (ALV) using the breathing bag Ambu and electrical stimulation, skeletal muscle, participating in the act of breathing. On the pre-imposed and fixed in the upper third of the trapezius muscle of each dog set of 12-24 electrodes were applied amplitude-frequency-modulated series of pulses of 1 MS duration of exposure to 1.5-2.0 with the pause (3-4) C. This method provides ventilation without the use of a mechanical respirator and without the use of complex bulky breathing apparatus [1]. The amplitude of the output voltage of the onboard bioelectrochemistry "Tone-2" controlled up to the minute volume of respiration using volumetry when fixing the limbs of the animal and provided that the maximum discharge of the forelegs behind his head.

Moreover, the amplitude of the stimulating signals bioelectrocatalytic "Tone-1 and Tone-3"reached 60 In between the electrodes is a pulse voltage, and current of 240 mA. However it is noted that the duration of the sessions, exceeding 15-20 min, exhaustion of the animal. A significant drawback is the large number of electrodes bioelectrocatalytic. In the end, it was investigated restore the life of the organism dogs in terminal hypoxia by mechanical ventilation with the use of bioelectrochemical skeletal muscle.

To provide emergency first aid in emergency situations and wounded on the field is HH using individual syringes-tubes antidote [2]. However, they have low sterility and integrity of the capsules with the medicine during long-term storage and do not have a high degree of operational reliability.

The closest medical-technical solution chosen as the prototype method is a known method for continuous monitoring of the technical condition of onboard aircraft systems, the functional status of the crew and its intellectual support in dangerous situations using the onboard active systems of safety on the basis of the informant critical condition of the pilot (IXL-2) [3]. This system, developed by JSC "Corporation "Russian system" together with the Federal state unitary enterprise RAC "MIG"Sri of military medicine of the Ministry of defense, was ergonomic and physiological tests, bench tests and flight tests on the MIG-29 UB with positive results.

The known method is the prototype includes automatic continuous control of motion parameters and the state of functioning of the life support system of a vehicle moving on the ground, under the ground, on water, under water, in air or space, the capacity evaluation of the erroneous actions of protection against the external environment, the prediction of dangerous condition of the crew by the contactless information retrieval metrics of the vertical position of his head, Les is full ventilation effort controls and integrity of the cab.

The known method prototype is in charge of issuing the crew of verbal information about an emergency situation, the elimination of irregularities and delays his actions, decisions about the restoration crew life by emergency supply of 100% oxygen and transfer of control of the vehicle and the automatic system in case of inadequate response of the crew to warning information, vehicle registration data about the status of life support systems and crew during emergency situations, and emergency broadcasting and reception at the command post group management signals about the dangerous condition of the crew and the recovery of his life.

The main disadvantages of the prototype method is:

1) the Known method does not provide restoration of normal spontaneous breathing in acute respiratory failure of the victim, for example, with the help of assisted mechanical ventilation.

2) In a known way there is no possibility of the suppression or reduction of pain syndromes, post-traumatic stress disorder, a heart attack with chest pain [2]. However, it is known that during the attack, chest pain, life-threatening heart arrhythmias, seizures, bronhialnaya cardiac asthma, bleeding during injury, myocardial infarction, and many other critical functional States of the victim delay emergency medical care to a member of the crew even for a few minutes can lead to his death.

The objective of the invention is to improve the safety and efficiency of vehicle movement by targeting medical emergency removal of a member of the crew of the critical state and restore it to life through a range of continuous monitoring, prediction and management capacity in combination with artificial ventilation of the lungs with oxygen, with the exception of the occurrence of fatigue, feelings of drowsiness and muscle discomfort crew member using bioelectrochemical during emergency situations in real time.

The problem is solved by means of information support for the activities of the member of the crew in real-time, automatic control of his health and generate control signals issued by the onboard systems of the vehicle in order to prevent accidents and rescue crew member in the event of loss of health or improper use of means and methods of protection. This manage, forecast the analysis of the status of habitats and modes of operation of the basic elements of the system life support (coolant), including oxygen-breathing apparatus (KDA), as well as issuing verbal warnings to the crew about the need to perform the required actions to prevent the occurrence of dangerous situations. When determining the fact of loss of crew health spending accelerated restoration of health, are issuing through the on Board radio to the command post messages about the loss of crew health, the issuance control parameters on-Board control system and registration for their preservation and further processing, in particular on the internal non-volatile memory information about the state of the crew, onboard systems, traffic conditions issued by the control signals during the whole operation time. These tasks prototype method [3] using the on-Board hardware-software complex (APC), including the unit of analysis of the status of the crew and onboard systems, evaluation of modes of motion, generation of control signals, the unit of electro mates, the processing unit of the sensor vertical position of the head, the ADF 100%oxygen to the beat of the breath of the crew, coupled with electropneumatically, sensor control of pulmonary ventilation, the sensor control the vertical position of the head, the sensor control compression of the handle (steering) upravleniyuosobymi means, the sensor response, the pressure sensor in your mask (the mask), the pressure sensor in the cameras high-altitude anti-g suit (aircraft, space or underwater suit), the height sensor in the mask (mask) of the suit and accordingly in the cab of a vehicle.

In acute hypoxia, or the threat of its development due to respiratory failure, including those associated with cessation of breathing, additionally carry out resuscitation, artificial ventilation of the lungs of the victim with the help of electromyostimulation skeletal muscles involved in the act of breathing, in the upper third of the Department of the trapezius muscle, the amplitude-frequency-modulated coherent series (wads) stimulating pulses at high frequency and pulse low-frequency modes by generating a sinusoidal waves (impulses) in five frequency ranges from 10 kHz to 30 kHz with a step and a modulation frequency of 5 kHz, continuous mode with frequencies from 10 kHz to 30 kHz and forth with a period of 4 C. In a pulsed low-frequency mode, the frequency of the signal in a series of pulses modulate smoothly increasing from 20 Hz to 200 Hz to maximum amplitude, followed by a decline to 20 Hz, and the increase of the amplitude in series to a maximum value of 100 mA, and its decline set in blue is odelname law (half). This stimulating low-frequency pulses are bipolar waveform with zero DC component. Resuscitation, artificial ventilation of the lungs affected by electromyostimulation of the respiratory muscles of the affected crew member carry pairs (active and passive) electrode, pre-imposed and fixed on the projection of the upper section of the trapezius muscles symmetrically right and left of the spine at a distance of 5-7 cm from the latter, and serves a series of stimulating pulses. The positive part of the low-frequency pulse has a rectangular shape - duration 2 MS, amplitude of 5 mA, and the negative part of the pulse is close to a triangular shape with a maximum amplitude of 100 mA, - 0.5 of the maximum amplitude pulse is 20 MS, the base - 50 µs equivalent load resistor 2 kω connected in parallel with the capacitor of 0.25 microfarad. The amplitude of the pulses in the high frequency and low frequency modes can be easily controlled manually from 0 to 100 mA on the same equivalent load, frequency modulation both modes include manually independently of each other, and the length of the series of low frequency pulses and pauses regulate separately from each other manually from 1 to 6 seconds with an interval of 0.5 C.

Artificial ventilate the lungs of the victim can be carried out in combination with exposure to pulsed electric current frequency 20-10000 Hz, pulse duration of 1 MS with a duty cycle of 4 s, duty cycle 2, (2 falls on impact, 2 - pause), and electromyostimulation exercise level of sensitivity when there is fatigue, feelings of drowsiness and muscle discomfort crew member directly in the process control movement of the vehicle continuously for 10-180 minutes or periodically every 1.5-2.0 hours, with electrodes, one of which is located in the middle third of the thigh, the other electrode is in the lumbar region. Thus, the intensive care unit mechanical ventilation with oxygen is carried out in combination with a decrease in fatigue, feelings of drowsiness and muscle discomfort of the crew directly in the process of control of the vehicle by acting on the muscles of the thighs and the back electrical impulses also modulated in amplitude and frequency. With fade and smooth drop from period 4±0,08 C, the limits of the frequency when the frequency modulation from 20±10 to 10000±10 Hz, a pulse duration of 1 MS have a form similar to the triangular equivalent load, R=2 kω and C=0,25 µf.

For security purposes, the current density of each electrode made of conductive rubber, for a set electromyostimulation equipment, a crew member does not exceed 2 mA/kV·cm in the her surface electrode, although the electrodes and the system they are committed to providing a convenient overlay, eat, individual adjustment and reusable sanitary handling.

In the analysed literature revealed no sources that describe the set of distinctive features, and the proposed solution is not obvious to a person skilled from the level of modern technology. Thus, it meets the criteria of the invention of "novelty" and "inventive step". The present invention can be used in extreme, military, aviation, marine and space medicine, and, thus, it meets the criteria of the invention "industrial applicability".

Comparative analysis of the proposed technical solution with the closest analogues and the prototype shows that the proposed method of recovery of crew life in extreme situations meet the criteria of the invention "novelty"because it differs from the known devices with new elements and relationships. The inventive method life recovery crew in extreme situations can significantly improve the safety and efficiency of vehicle movement by targeting medical emergency removal of a member of the crew of the critical state is and the expense of complex continuous control, prognosis and management capacity in combination with artificial ventilation of the lungs with oxygen, decrease fatigue, drowsiness and muscular discomfort with bioelectrochemical during emergency situations in real time.

It gives the right to conclude its compliance with the criterion of "significant differences". Received positive feedback from pilots about the effectiveness of the proposed method in long flights.

According to flight crews, an important feature of this method is semi-automatic mode, electromyostimulation, crew members, not distract pilots from performing work operations in flight by plane long range.

Sensors 3-6 onboard informant 1 critical state agriculture provide control of pulmonary ventilation in respiratory rate from 5 to 60 units/min, the estimate of the duration of breathing pauses in the range 0...30 with control compression of the handle (steering) control, stock control effort on the pedals when an overload that exceeds the threshold, control the vertical position of the head in predetermined zones, due to the peculiarities of the cabin vehicle, the control response crew member on a verbal request. Sensors 3-6 APK does not have galvanic contact with the body of a crew member, do not require prior installation and configuration does not have a disturbing actions during his work. AIC input information signals compatible with the following onboard systems of the mi: oxygen supply (KCO), Coolant, VPC (spacesuit), radio altimeter (gauge), automatic control system, sensor overload, intercom or equipment internal communication and switching. APK on weekends, the control signals compatible with the following onboard systems: oxygen supply KCO, coolant, VPC (spacesuit), onboard radio equipment, internal communication and switching, voice informer, automatic control system, the musculoskeletal system automation system flight control and landing AIDS, navigation system, on-Board recorder information. As the sensor 4 availability control of pulmonary ventilation uses a proximity sensor oxygen pressure of KCO. Sensor 3 control the vertical position of the head allows obtaining information about the vertical position of the head of a crew member as evidence of the normal tone of the neck muscles. As the sensor uses a digital video camera 3, aimed at his face and connected to the unit 2 analysis of the management Board of the informant. She does not have a disturbing influence on the work of the crew. The efforts sensors 5 on the pedals provide information on the value created by the pilot-operator effort on the pedals of the vehicle. Preventing action on the pilot sensors are not OK is given. The compression sensor 6 handles (steering) control TC provides data about the working position of the hand of the pilot or operator on the handle (steering wheel) control on the dynamics of its influence on handle (handlebar). The contactless sensor 6, interference in the work of the crew has not. The sensor response provides feedback crew member-agriculture and obtaining information about the realized actions of the pilot-operator, allowing him to adjust the system response time. As the sensor uses one of the existing controls equipment vehicle, such as a RADIO button, or voice response crew member. The sensor of cabin depressurization 7 - the pressure in your mask space or the pressure sensor (altitude) in the cockpit provides timely detection of cabin depressurization TC, high pressure in the cabin of the vehicle. The sensor 7 staff from KCO, showing emergency balance of oxygen or the failure of the RUC. AIC has the capability of interfacing input and output with onboard equipment vehicle through channel multiplex exchange according to GOST 26765.52 through the code line GOST 18977 for signal analysis: a dangerous height current height - radio altimeter, current speed, modes with automatic control system (ACS), the current overload - sensor overload and other

AIC provides operational control of the condition of habitat (cab is), and operating modes the basic elements of the coolant, the adequacy of the habitat. In case of an emergency variance shall exercise sound crew alerting to the need to reduce high altitude or rise from the depths. APK dynamics of breathing, head position, the position and dynamics of the hands and feet on the controls, reactions to speech testing in conjunction with the analysis of modes of motion (height, speed, overload, modes ACS), state of the environment and the coolant performs automatic tracking of the health of the crew of the vehicle.

In the case of actions of the crew, inadequate desired situation of the vehicle movement, APK issuing the crew of the corresponding speech warnings to perform certain actions to prevent critical situations and verbal warnings about the state of the environment (cab) and the coolant. Thus, informational support of the activities of the TC crew recognition of emergency situations (depressurization of the cabin, the lack of oxygen and the like, which are not covered by other information systems TC (equipment voice warning system for the collection and registration of information). With the loss of the crew to control the movement of the TC hardware-software system implements a mode for accelerating the recovery of rabotosposobnom the STI crew by filing 100% oxygen to the rhythm of my breathing. Is used for this purpose established in the respiratory tract of a member of the crew electroneurography EPA, which has no disturbing effect on the crew, not prevents it from breathing. After recovery of the crew is the transfer of management functions of the vehicle. Criterion normalization health of the crew are signals from sensors, demonstrating the elimination of emergency situations, as well as confirmation of crew awareness of their actions through the sensor response. AIC provides the issuance of the following verbal warning commands: "Pen abomi", "Head lift", "the Mask draw", "Cabin depressurized. The mask draw" ("the Second mask draw". "The cabin depressurized. The second mask draw for double TC), "Cabin depressurized", "cabin high pressure Oxygen check", "Lower ("Rise") of emergency", "air (room) the dangerous condition" - this message is transmitted to the command post via on Board the station, "the Board (number) condition normal" - this message is transmitted to the command post via on Board radio, APK healthy."

Critical member of the crew assesses the emergency doctor at the command post and decides to Imprimerie victims of Bioelectrography. Complete 9 electromyostimulation apply the foundations of the second kind: "mechanical ventilation", at which carry out joint impact on crew member a series of pulses of 10 high-frequency and low-frequency 11 generators.

In acute respiratory failure on the background of spontaneous breathing and / or pain, for example, in the chest, strong heartbeat or a gunshot wound, do artificial ventilation of lungs affected with electromyostimulation skeletal muscles involved in the act of breathing, in the upper third of the Department trapezius muscles amplitude-frequency-modulated coherent series of high-frequency generators 10 and 11 low pulse kit 9 electromyostimulation equipment crew member. Moreover, the maximum amplitude of the series of pulses of duration 2 MS set the level of expressed excursions of the thorax. When this amplitude modulation carry out positive half-sine pulse with amplitude from 0 to the maximum value, the frequency modulation produced by the repetition rate in the range (20-200-20) pulses in 1 second Artificial ventilation of the lungs of the victim performed in conjunction with a pulsed electric current frequency 20-10000 Hz, pulse duration of 1 MS with a duty cycle of 4 s, duty cycle 2, (2 falls on impact, 2 - pause), and electromyostimulation assests the Ute at the level of the threshold when there is fatigue, feelings of drowsiness and muscle discomfort crew member directly in the process control movement of the vehicle continuously for 10-180 minutes or periodically every 1.5-2.0 hours, with electrodes, one of which is located in the middle third of the thigh, the other electrode is in the lumbar region.

Artificial ventilation of lungs affected by electromyostimulation of the respiratory muscles of the affected crew member carry pairs (active and passive) of the bipolar electrode 15, a pre-imposed and fixed on the projection of the upper section of the trapezius muscles symmetrically right and left of the spine at a distance of 5-7 cm from the latter, and serves a series of stimulating pulses of duration 2 MS, amplitude modulated from 0 to a peak value and a repetition frequency in the range (20-200-20) pulses of 1 s duration series and rests, adjustable separately from each other manually, from 1 to 6 seconds (with an interval of 0.5 s). Before beginning operation of the muscles of the thighs in the area of the middle third and the back in the lumbar region (option 1) impose and fix the bipolar ring electrodes 16, pre-moistened with water or 4%soda solution. The electrode 16 is connected to the generator 11 low-frequency pulses through the output stage 13 and modulate the 12 at-a-kind work of generator 11 "Exception feelings of fatigue, drowsiness and muscle discomfort. In the process of implementation of operator activity when signs of fatigue (fatigue, drowsiness and muscle discomfort after an average of 2 hours of continuous operation include the generator 11 low-frequency pulses of the kit, install the amplitude of the output signals at the level of muscle contraction (below the threshold of pain) and act for 10-15 minutes. This increases the flow of afferent activity from receptors located in the skin and muscles, in the higher parts of the Central nervous system, and the procedure is perceived subjectively as vibratory muscles without distracting from the performance of operations.

For security purposes, the current density of each of the electrodes 15, 16 made of conductive rubber, for a set electromyostimulation equipment 9 crew member does not exceed 2 mA/kV·cm over the entire surface of the electrode, and the electrodes 15, 16 and 17 they are committed to providing a convenient overlay, eat, individual adjustment and reusable sanitary handling.

The simulation of long-term operator of the aviation profile in terms of effects on the body hypoxia (altitude 3500 m) and acoustic noise (100 dB) showed that the proposed method helps to eliminate muscle discomfort with long-term slave is the same and increases by 20-40% as professional activity, increases functional resistance to hypoxia. According to electroencephalography activating effect of electrical stimulation is manifested in the reduction of the Delta-rhythm of 48%, increasing the energy of theta rhythm by 122% and the alpha rhythm by 124% compared to the level recorded before the session of electrical stimulation. Version 2 the application of the method consisted in continuous electrical stimulation of the muscles of the back and hips during the entire period of operator activity in the conditions of the 3-hour "flight". He showed that the efficiency of the operator is maintained high, while in the control was, there is a clear trend toward an increase in the number of errors by increasing the duration of the operation.

The efficiency of the practical implementation of artificial lung ventilation, elimination of feelings of fatigue, sleepiness and muscle discomfort crew member using the electrical stimulation was assessed in terms of the 9-hour transmeridian flight on the Il-62, carrying out flight on a route Tartu-Petropavlovsk-Kamchatsky-Tartu. It was established that the use of electrical stimulation as the occurrence of fatigue and effects of muscular discomfort (duration of the session 15-20 minutes every 2 hours flight) contributed to the preservation of optimal functional state and performance years the CSO composition during the entire flight. In control experiments, the signs of fatigue and reduced quality of activity was determined with 4-5 HR flight.

The inventive method of restoring the activity of the crew in emergency situations can be used as modernized and promising the highly maneuverable aircraft like the MIG-29, MIG-31, su-27, su-30, civil transport aircraft destination. The inventive method allows to carry out:

automatic continuous control of motion parameters and the state of functioning of the life support system of a vehicle moving on the ground, under the ground, on water, under water, in air or space,

the capacity evaluation of the erroneous actions of protection against the external environment, the prediction of dangerous condition of the crew by the contactless information retrieval metrics of the vertical position of his head, pulmonary ventilation, effort controls and integrity of the cab.

The inventive method is in charge of issuing the crew of verbal information about an emergency situation, the elimination of irregularities and delays his actions, decisions about the restoration crew life by emergency supply of 100% oxygen and transfer of vehicle control/automation system in the case of NEA is aquatest response crew to warning information, produces on-Board data logging on the conditions of the life support systems and crew during emergency situations, and emergency grant through the on Board radio broadcast and reception at the command post group management signals about the dangerous condition of the crew and the recovery of his life.

The inventive method life recovery crew in extreme situations, you can use artificial lung ventilation without the use of bulky bulky breathing apparatus operating on the principle of "blowing" air into the lungs; to exclude trauma of the parenchymal tissue of the lung, since the degree of stretching of lung tissue is determined by the mechanical ability of the respiratory muscles when exposed to the neuro-muscular system of the victim adequate electrical stimulus; to improve gas composition of the blood in the absence of negative effects on the cardiovascular system of the victim, which is typical for respiratory breathing; increase of 2.0-3.5 times the minute volume of breathing with spontaneous breathing, due to the fact that the magnitude of the minute volume of respiration is determined by the amplitude of the stimulating signal onboard Bioelectrography.

The proposed method provides the physiology of the respiratory act, effective gas exchange,the possibility of effective ventilation in critical breathing disorders, especially against the background of maxillofacial trauma or injury of the victim.

Technical result achieved when using the proposed method is to improve the effectiveness of emergency medical care in acute respiratory failure, hypoxia, feeling of fatigue, sleepiness and muscle discomfort.

The inventive method is promising for emergency medical assistance in the centers of massive defeats, disasters, accidents and disasters, on the battlefield, including in the conditions of high-altitude protection suit, the output (in space) or marine suit, gas mask, as well as in terms of the presence of the human body in weightlessness of space flight, underwater underwater vehicle (boat) and surgical intensive care units in advanced stages of medical evacuation.

Figure 2 shows the bipolar form of a single stimulating pulse. Elektrostimulirovannaya crew in extreme situations carry on 8 galvanically isolated channels, working in pairs on 4 channels. The output signal is a sequence of bipolar pulses of current in the RC equivalent load resistor 2 kω connected in parallel with the capacitor of 0.25 microfarad.

Elektrostimulirovannaya carried out in high-frequency and pulsed modes. In pulse mode with kulinowski pulse has a bipolar waveform (figure 2), moreover, the square of the positive and negative pulse equal to the positive part of the pulse has a rectangular shape with duration of 2 MS, amplitude 5 mA; negative part is close to triangular with a maximum amplitude of 100 mA at 0.5 max pulse duration is 20 MS, the base - 50 µs equivalent load. The amplitude of the pulses smoothly manually adjust to 100 mA equivalent load, and the square of the positive and negative parts remain equal.

Figure 3 shows the generation of sequential burst sends modulated in frequency and amplitude in the pulse mode. Figure 4 shows examples of changes in the length of messages and pauses in the pulse mode elettrostimolatore.

In the pulse mode to generate a serial pulse packet - promises, modulated in frequency and amplitude (see figure 3). The duration of the promises and breaks regulate separately from each other manually from 1 to 6 seconds, with an interval of 0.5 s (figure 4). The increase in amplitude in the stack to a maximum of 100 mA and its decline asked sinusoidal - half.

The frequency of the signal in the stack modulate smoothly increases from 20 Hz to 200 Hz to maximum amplitude, followed by a decline to 20 Hz, with a frequency of 20 Hz corresponds to the minimum signal amplitude and frequency 200 Hz - max is th.

Electrical stimulation of the crew in the high frequency mode is carried out by generating sinusoidal oscillations with a frequency of from 10 kHz to 30 kHz with a step of 5 kHz in five ranges.

Figure 5 shows the modulation of sinusoidal oscillations with a frequency of 5 kHz. Figure 6 shows the form of a high frequency signal with the low frequency modulation. Figure 7 shows the shape of the sinusoidal signal in continuous mode with frequency modulation.

Sinusoidal oscillations modulate a frequency of 5 kHz (figure 5). While the possibility of further low-frequency modulation (20-200-20) Hz with an amplitude of up to 100 mA and period 4 C.

Waveform with double modulation is depicted in Fig.6. Elektrostimulirovannaya crew provide continuous mode with frequencies from 10 to 30 kHz and forth with a period of 4 (Fig.7). Frequency modulation include manually independently of each other, the amplitude (0-100) mA set manually.
