Description

 The invention relates to medical equipment, namely to magneto and vibrotherapy, and can be used in cosmetology, dermatology, as well as for complex effects on the human body during prevention and treatment.

 It is well known that the alternating magnetic field of low frequency has a positive effect in the treatment and prevention of various human diseases, and the continuous magnetic field has a sedative effect, and intermittent - exciting, stimulating effect, which is especially amplified in an irregular mode.

 Such a pulsating (pulsed) magnetic field provides unidirectional electrodynamic forces that act on charged particles in the body (anions, cations, polar molecules), moving them. This allows you to activate in the body (in the area of effect) the process of diffusion, mass transfer, metabolism, increases the functional activity of individual organs and the body as a whole, i.e. a new therapeutic method is being implemented - magnetophoresis, i.e., a combination of two simultaneously acting therapeutic factors: a magnetic field and a medicinal or cosmetic preparation (in the form of a cream, gel, etc.), used both in massage and in treatment.

 One of the problems of modern matitotherapy is: firstly, the inconvenience of operation due to the cumbersomeness of medical equipment, and secondly, the low therapeutic effect as a consequence of the first, because not all parts of the human body can be subjected to medical procedures, thirdly, the patient safety issue is separate, because currently, mainly for the supply of inductors, an industrial electric network ~ 220V / 50Hz is used.

 It is known "Device for magneto-and vibrotherapy" (see RF Patent N2.101.039 class A 61 N 2/00), containing an electromagnet in the form of a core with a coil and an applicator, the latter is made in the form of a core of a coil or part thereof, and in parallel with an electromagnet a voltage amplifier is connected, and a membrane is additionally placed in the applicator.

 The disadvantage of this device is that the magnetic field in it is continuous, and this significantly reduces its use, in addition, there is no regulation of the frequency and amplitude of the magnetic field.

 Domestic instruments for generating a low-frequency magnetic field are known: "Pole-1", "Pole-2", "Pole-101", "Magniter", "MAG-30", etc. (see. "Instruments and control systems" N 5 - 93 g, p. 13-14).

 All of these instruments contain a part that is fundamentally common for all: solenoids from an insulated wire, creating an electric and magnetic field of a certain size and configuration, which does not allow to quickly vary the shape and dimensions of the magnetic field, referred to a unit of MT, and the drive mechanisms are too bulky.

 Famous Japanese magneto-therapeutic apparatus "Magnetizer" (see G. R. Soloviev "Magneto-therapeutic apparatus", M., Medicine, 1991, pp. 146 - 147), in which inductors create a magnetic field with a frequency of 50 - 60 Hz, this field is accompanied by vibration, and vibration occurs immediately after switching on, and heating gradually. The device is designed in a stationary version in the form of a chair and inductors are mounted in its various parts, which, of course, significantly limits its use, for example, it cannot be used for massage or facial treatment.

 It is known to use a traveling pulsed low-frequency magnetic field in the treatment of patients based on the Alimp-1 apparatus, which consists of a master oscillator, a power amplifier, and inductors. The apparatus generates a magnetic field with rectangular pulses with a frequency of 10-100 Hz, with magnetic induction of 3 mT in the center and 10 mT at the edges of the inductor (see. "Problems of balneology, physiotherapy and physiotherapy", N 4 - 89 g., M ., Medicine, pp. 43 - 46).

 The disadvantage of this apparatus is its limited use, mainly for the treatment of lumbar osteochondrosis, due to its cumbersomeness due to the use of solenoids as inductors, which also require additional safety measures, because AC power 220V / 50Hz is used to power the solenoids.

 It is known "Device for treating a person with a magnetic field" (see RF patent N 2104720 class A 61 N 2/02 of 05/31/95), containing a signal conditioner, power amplifier, magnetic inductor, current sensor and current regulator, comparison unit , unit for setting the operating time - PROTOTYPE.

The disadvantage of this device is:
- inconvenience in operation due to the bulkiness of the inductors made on induction coils;
- low therapeutic effect due to the use of a continuous constant magnetic field of industrial frequency 50Hz.

An object of the invention is to increase the therapeutic effect and increase operational properties due to:
- providing the possibility of prophylaxis, treatment and massage of any part of the human body, including the face;
- providing the ability to adjust the output magnetic parameters in a wide range;
- ensuring the safety of patients and attending personnel.

The device can operate in three modes:
- manual setting of output parameters;
- automatic setting of parameters (touch mode);
- scan mode.

 Manual mode.

 In this mode, all output parameters of the device (output power, pulse repetition rate, period) are set manually using the BUI2 keyboard. The device in this mode works as follows.

 All units of the device (from 1 to 6 positions in FIG. 1 inclusive) are structurally located in one housing, on the front panel of which all the necessary controls and displays are displayed.

 When the power is turned on and the supply voltage exits to MP1 mode, it generates a general zero-setting signal and the device goes into the “Standby” mode, the corresponding light on the front panel lights up, which is not shown on the diagram), i.e. the device is ready to enter the parameters. On the front panel, the "Manual mode" button is pressed, then the "Frequency" button (both with memory and backlight). Then, the “Job” button is pressed and held in this position, while MP1 begins to sort (increase) the frequency with a resolution of 1 Hz, starting from one. When the desired frequency (set by medical recommendations) is reached (control by the indications of seven-segment indicators of the front panel), the "Task" button is released. The selected frequency value is automatically recorded in non-volatile memory (ENZU) MP1. Then the “Time” button with memory and backlight is pressed (the “Frequency” button is previously disabled). The "Task" button is pressed and held again until the desired duration of the procedure is established, which is also recorded in the MP1 ENZU; the control is the same. The "Time" button is turned off, the "Period" button is pressed (with memory and backlight). The “Job” button is pressed and held, etc., then the value of the required power is also entered.

 It should be noted that the pulse repetition rate is set in the range from 1 to 250 Hz, the pulse repetition period adjustment range is from 0.2 to 8.0 s and continuous, the procedure time is from 1 to 30 minutes, and the magnetic induction power is up to 15 mT.

 Inductor 7 is applied to the desired part of the patient’s body and the “Enter” button is pressed (with memory and backlight), the “Standby” lamp goes out, and the set and selected procedure parameters (frequency and period) via the second data bus from MP1 (output 14) through FS4 (output 29) in the form of control signals are supplied to SLB5 (input 30), where they are finally formed in the output sequence of pulses with specified frequency and power parameters. From the output 33 SLB5, the signals are fed to the input 34 of the inductor 7, where they are converted into an electromagnetic field, and the inductor vibrator oscillates, of course, with the frequency of the electromagnetic field. At the end of the set procedure time, the timer signal MP1 will turn off the mode, the "Enter" button will turn off, the "Standby" lamp will light on the front panel. The device is ready for a second procedure or for a set of other parameters.

 Scan mode.

 The Scan Mode button (with memory and backlight) is pressed, and the Manual Mode button is automatically turned off. In this mode, the pulse frequency changes according to a sinusoidal law (the data of this mode are programmed in advance), and the setting is made according to three parameters: the duration of the procedure, the upper scanning frequency and the pulse repetition period (from 0.2 to 8.0 s and "white noise") . Then, an inductor 7 is also applied to the desired area of the patient’s body, the “Enter” button is pressed, and then everything is as in manual mode until the end of the procedure time.

 Touch mode

In this mode, tuning is performed according to two parameters: the duration of the procedure and the initial frequency (the power in this mode is constantly average). The "Sensor Mode" button (with memory and backlight) is pressed, while the "Scan Mode" button is automatically turned off. The "Enter" button is pressed, while SB3 starts to work, the master oscillator of which is tuned to a specific initial frequency. This frequency from output 37 goes to information input 38 of IB6, where it is converted into a sequence of pulses, and after additional transformations and synchronization with a clock frequency f, the _{clock cycle} (input 26) goes to the counter, then to the buffer register and the fourth data bus (output 28) on FS4 (exit 27). With FS4 (output 11), this pulse sequence is supplied on the first data bus to the input of БУИ2 for display on the indicator, and, on the other hand, in the form of control signals through the first control output 29, it is supplied to СЛБ5 (input 30) for controlling power thyristors. From the output 33 of SLB5, this pulse sequence is fed to the inductor 7 (input 34), applied to any part of the patient's body (output 35). A sensor is introduced into the inductor 7, which is a simple brass plate with a diameter of approximately 5-6 mm and a thickness of 1 mm. This plate through a coaxial cable is connected directly to the input SB3 (input 36), specifically with the control input of its generator, making an additional capacity. As a result, the initial frequency of the SB3 generator varies depending on the physical state of the patient’s body part, to which an inductor with a sensor is attached. This changed frequency is measured again by IB6 and through FS4 and SLB5 it enters the inductor 7 as a sequence of pulses, acting on this part of the body. As a result of this magnetic and vibrational action, physical changes of a given part of the patient’s body take place over time, as a result of which its capacity will change, as a result of this, the frequency of the SB3 generator will change and the process will continue in a circle to some specific constant frequency value ( as a result of stabilization of the physical state of the body part) or until the end of the procedure.

One or two inductors can be connected to the device (there are two equivalent outputs). Inductors are used in three types:
- for cosmetic massage in the form of a cylinder with a diameter of 22 mm and a length of 45 mm (with or without a touch sensor);
- for body massage in the form of four cylinders on a common base 12 mm thick and 87 mm in diameter. Cylinder diameter 22 mm, from the base 20 mm (touch sensor in one of the cylinders);
- for treatment in the form of two disks with a diameter of 40 mm, a thickness of 25 mm (in one of them there may be a touch sensor).

 When two inductors are turned on, the sensor must be in only one of them.

 The use of such a device for magneto- and vibrotherapy allows carrying out therapeutic procedures on any part of the patient’s body, as well as conducting massage procedures. All procedures can be carried out both in hard-set parameters of the pulse sequence, and in variations, depending on the individual characteristics of the patient. It should be noted that the simultaneous use of inducers for treatment and massage increases the therapeutic effect due to the fact that the output parameters of the pulse sequence in both cases are the same when two inductors are applied - one, for example, to the lumbar region, and the other - to the face their positive influence on each other, a kind of quasi-resonance.
