Description

 The invention relates to medicine, namely to physiotherapy, and can be used to stimulate recovery processes in the body after stressful conditions that cause the development of pathological conditions or exacerbate disorders of the central nervous system. It can be used as a preventive tool before performing work related to physical, emotional and mental overload.

 An analogue of the proposed device can be considered a regular tape recorder, providing acoustic impact on the auditory analyzer with specially selected musical compositions. This method of influencing the human central nervous system for therapeutic purposes is called music therapy (L. S. Brusilovsky. Music therapy: a Guide to psychiatry. -M.: Medicine, 1979). Thanks to the use of this device, the effect on the central nervous system and the body's vital functions regulated by its process is mediated through the auditory analyzer (ear) with subsequent transmission of excitation to the auditory region of the cortex and to the subcortical structures through a complex system of nerve connections.

 Such a complex organization of the body's response to acoustic effects and a large load on the auditory analyzer, especially on its cortical end, in patients with people imposes restrictions associated with active technogenic environmental influences (various kinds of noise, vibration, television and radio signals).

 Of the known devices, the closest in technical essence to the proposed device for the implementation of the central nervous system is the Micro-Linar electro-tranquilization apparatus commercially available from the TsNIITmash experimental plant (passport). It contains a master oscillator, an exposure mode switch, an inverter, an amplifier limiter, a preliminary and output amplifier, an average current limiter, an indication and control device, a timer, a protection unit, a voltage converter, a set of electrodes for supplying an acting pulse voltage from the device to the patient. Such a device allows to obtain a sequence of rectangular pulses with a repetition rate of 1000 Hz and a duration of exposure of 0.25 and 0.75 ms ± 20%, which are applied to the electrodes mounted on the patient’s head.

 The disadvantage of the prototype should be considered that after 10 minutes of exposure is the adaptation of the body to the pulse effect, which naturally leads to a decrease in the effectiveness of treatment.

 The disadvantages include its use of a complex electronic circuit.

 The technical result of the invention is to restore the functional connection of all body systems and simplify the design of the device.

 The specified technical result is achieved by the fact that in a known device containing a master oscillator, a switch of exposure modes, an inverter, an amplifier limiter, a preliminary and output amplifier, an average current limiter, an indication and control device, a timer, a protection unit, a voltage converter, a set of electrodes for feeding the acting impulse voltage from the device to the patient, an audio player or other devices reproducing music recordings are used as a driving generator otorrhea connected to the emitter follower which is connected in series with an amplifier connected to the step-up transformer, the output of which is connected in series with the measuring head and the AC supply to the electrodes set on the CNS electrical signal varying sinusoidally corresponding to a particular piece of music. Such a signal is characterized at each moment of time by a change in the duration, amplitude and frequency of exposure, which makes it possible to obtain a qualitatively new physiological stimulus, to which the organism does not become addictive during the entire course of treatment. In addition, this combination of essential features can significantly simplify the design of the device.

 In FIG. 1a shows a block diagram of a device for the rehabilitation of the central nervous system. In FIG. 1b shows a structural arrangement of functional units of the flowchart. Figure 2 shows a General view of the device, explaining its operation.

 On figa shows a block diagram of a device. It includes a power source 1, an audio player 2, an emitter repeater 3, a signal power amplifier 4, a step-up transformer 5, an AC measuring head 6 and an electrode 7, which are mounted on the patient's head. In FIG. 1b shows that the device consists of 3 main nodes. Node I is an audio player 2, from the output of which a harmonic-shaped signal is supplied to electronic node II, which includes blocks 1, 3, 4, 5, 6, and at the output of which an amplified and load-coordinated signal is supplied to node III, which is a set electrodes 7, which are mounted on the patient’s head. In FIG. 2 shows a general view of the device, which together with FIG. 1b will allow you to understand the operation of the proposed device.

 Such a device works as follows. The plug 10 is inserted into the voltage network 220V, then the switch 8 is set to the "on" position, and the signal lamp 9 should light up. A cassette is inserted into the audio player 2, with the corresponding music fragment. By pressing the “start” button in the audio player 2, the harmonic signal is fed to the emitter follower 3, then the power amplifier 4 and the step-up transformer 5. From the secondary winding of the step-up transformer 5, the signal passes through the measuring head of the alternating current 6, which carries information about the value of the stimulating current, and arrives at the electrodes 7 mounted on the patient’s head. Using the volume control of the audio player 2, you can adjust the value that stimulates the current within the specified limits. At the request of the patient, the effectiveness of treatment can be improved by connecting the patient with headphones 11.

The proposed device for the rehabilitation of functional disorders of the central nervous system provides the ability to apply an electrical signal modulated by the corresponding musical fragment to the central nervous system. It allows you to prevent the development of stress measurements, strengthen the inhibitory processes in the central nervous system, and also improves the "quality of life", provides an increase in the level of regulated effects of the central nervous system on the autonomic functions of the body and corrects central nervous system disorders. The proposed device is also intended:
- to reduce stress after emotional and physical overload in healthy people;
- for the prevention of diseases in people with increased sensitivity to stressful effects, as well as people whose activities are associated with private and / or intense psychoemotional overloads;
- for the treatment and rehabilitation of patients with chronic somatic diseases (initial stages), the pathogenesis of which plays an important role in emotional overstrain (hypertension, peptic ulcer and duodenal ulcer, bronchial asthma, biliary dyskinesia, atopic dermatitis, etc.);
- to increase the effectiveness of other methods of psychotherapy (autogenic training, progressive muscle relaxation, etc.) and control the degree of relaxation during treatment. The results of studies of this device on volunteers showed that, after one exposure session for 20. ..30 min, an improvement in the general condition is noted, anxiety and stress are relieved. According to electroencephalographic studies in these patients, an increase in 1 rhythm is noted. Favorable changes from the peripheral vascular system were also found.
