Description

Software-controlled Synchropulsar-1

The utility model relates to the field of medical technology and relates to the optimization of physiotherapeutic methods of exposure using interference currents.

Treatment with interference currents, in comparison with amplipulse therapy and treatment with diadynamic currents, has the following main advantages:

1) is better tolerated by patients, especially children:

2) the irritating effect occurs deep in the tissues;

3) the ability to use high current strength.

The main disadvantage of this method is the rapid adaptation of tissues to interference currents due to their weak irritating effect, which inevitably leads to a decrease in therapeutic effectiveness. For this reason, the domestic industry does not produce devices for treating interference currents (V.G. Yasnogorodsky) DI). .

Closest to the proposed technical solution for optimizing the impact is the introduction of an automatic mode that changes the frequency of exposure during the treatment procedure, which greatly eliminates the noted drawback. In this case, the device in question contains constant and variable frequency generators connected in series with an amplitude amplifier and through isolation transformer with impact electrodes. The variable frequency generator is connected to a manual frequency control switch and to an automatic frequency control unit (V.S. Ulashchik). (2).

The disadvantage of this method of optimizing the impact using interference currents is that the automatic mode only implements frequency changes against a background of a constant amplitude of the effect and, most importantly, is not synchronous with the hemodynamic parameters i.e. excluding patient biorhythms.

The problem is solved as follows. that the impact of interference currents is carried out in a program-controlled mode with pulse modulation of the frequency and amplitude of the action in synchronism with the rhythms of the pulse emission and respiration using special sensors.

The utility model works as follows. Quartz oscillator 1 generates a reference frequency of 20 MHz. from this frequency, generator 2 generates a frequency of 4882 Gi, and generator 3 generates a variable frequency in the range of 4884-5032 Hz. Each signal, being modulated both in amplitude and frequency by pulse emission and respiration by signals from pulse sensors. Respiration and a variable frequency generator comes from modulators of constant 8 and variable frequencies 9. Through galvanic isolation transformers 10 and I, through relay block 13 to the switched fours of the electrodes 14-29.

The signal from the output of the pulse sensor 33 is amplified by an amplifier-comparator 34 and converted into U-shaped pulses that are directly proportional in time to the maximum current pulse output. From the output of the comparator amplifier 34, the pulsating current is supplied to the amplitude controller of the pulse component .35 and to the input of the terminal adder 36, after which the signal is amplified in the amplifier 37 and fed to the input of modulators 8 and 9.

The weak signal from the respiratory sensor 39 is amplified by an amplifier 40, after which it is supplied to the amplitude regulator 41 of the respiratory component. The adders 38 and 36 are used to obtain the sum of the amplitudes: pulse, respiratory and constant level components, the adders are connected in series with the amplifier 37. From the output of which the signal goes in two directions: - in the first direction on modulators 8 and 9 of variable and constant frequency; and in the second direction - on ADC 30. descrambler 31 and linear indicator 32.. -, - S of the pulse coming from the amplifier-comparator 34 and, in accordance with the program recorded in ROM 1, writes information from ROM about the current relay switching in relay block 13 to the state register of relay 5 and also writes it to the register frequencies b information on the frequency necessary at a given time. The variable oscillator must produce a frequency. 3. The preset relay switching at each moment of time determines the four electrodes, which is connected via the relay unit 13 to the outputs of the galvanic isolation transformers 10 and I. The electrodes are set in such a way that the contacts of the same name on each channel are located at opposite vertices of square C of Fig. 2). As a result of the addition of two frequencies between the four electrodes, a pulsating electric field is formed in the patient's body, with a beat frequency equal to the frequency difference between the frequency channels. The beat amplitude, in turn, is modulated by the total analog signal from the output of the adder 36 through an amplifier 37. The electrodes 14-29 are switched by a relay unit 13 into seven fours in turn in accordance with eighteen programs recorded in ROM 4 for the treatment of various diseases. Such switching creates the effect of a traveling wave and provides the necessary therapeutic effect. The utility model is illustrated by the following example of switching the electrodes and the frequencies supplied to them to implement the treatment program for the treatment of zndarteritis (Table).
