Description

The utility model relates to medical equipment, namely to equipment in the field of dentistry, physiotherapy and neurology and can be used to develop a dental device that acts with low-frequency current pulses on tissues, muscles and nerves of the maxillofacial region, as well as other areas.

A device for electrical stimulation of muscle groups [copyright certificate SU on IZ No. 801839]. It contains a block for generating stimulating pulses, output pulse shapers, electrodes, and a number of other nodes.

Also known are devices called “electrostimulator” and “devices for electrical stimulation” [SU copyright certificates from IZ No. 865299, No. 1153140, No. 1680176, RU patents from IZ No. 2091089, No. 2125828, No. 2131275, No. 2149040, No. 2260450].

The closest analogue to the claimed utility model is a device for electrical stimulation [RU patent of IZ No. 2091089]. This device is intended for percutaneous electrical stimulation. It is characterized in that it contains a pulse generator, an envelope shaper, a signal shaper, an indicator and an electrode, as well as a number of other nodes necessary for the implementation of the tasks of the nodes and blocks.

The disadvantage of this device, like the other of the above, is the limitation of the possibility of its use in medical practice. In addition, this device does not allow you to simultaneously connect two active electrodes.

The objective of the claimed utility model is to reduce pain and the effect of electric shock by achieving muscle contraction and deep neurostimulation.

The essence of the claimed utility model lies in the fact that the stimulator-analgesic device has a housing in which are placed a serially connected master oscillator, a signal conditioning unit, an output stage, an output transformer, the output stage being connected at the other end to a signal level generating unit, a zero control unit , a power supply, and the signal conditioning unit at the second end is connected in series with the control pulse generation unit and the burst generator; on the front side of the case, a working panel is made, on which a switch, frequency and amplitude voltage regulators, a stimulating current light indicator and socket-outlets for cables to electrodes: percutaneous and intraoral are displayed.

The technical result of the utility model is that the inventive electrical stimulator-analgesic according to the presented scheme is capable of supplying packs of low-frequency pulses with high-frequency filling, which causes muscle contraction and deep neurostimulation without the appearance of pain and the effect of electric shock. The path and mechanism for obtaining this effect is technical, and the application of the result is equipment for medicine.

The electrical stimulator-analgesic device is illustrated using FIG. 1 - a drawing of the electrical stimulator-analgesic device, which shows the parts and assemblies located on the panel of the body, figure 2 - block diagram, which contains the missing parts and blocks in the drawing, because they are inside the body:

The inventive electrical stimulator-analgesic device has a housing 1, cable 9 and electrodes 8. The front side of the housing 1 is presented in the form of a working panel 2, on which are placed the frequency controllers 3 and voltage amplitudes 4, a light indicator of the stimulating current 5, socket-terminals 7 for connecting cables 9 to the electrodes 8. Electrodes 8 are of two types: percutaneous and intraoral. And inside the housing 1 are placed: a generator 10 - master and 11 - a generator of packs, blocks 12, 13, 15, 17 and other elements of the flowchart 14, 16, 18, presented in detail below. The master oscillator 10 generates a pulsed signal in the form of a meander with a frequency of the order of 5 kHz, which is supplied to the signal conditioning unit 12. The burst generator 11 generates a pulsed signal supplied to the control pulse generating unit 13. From the output of this unit, control pulses of positive polarity lasting 7 ms. and the repetition rate, which can be changed in the range of 10-50 Hz, enter the signal generation unit 12, which sets the form of the output signal. The output signal of the signal conditioning unit 12 is supplied to the control input of the output stage 14. The signal from the unit is supplied to the power input of the stage 14

the formation of the signal level 17, which sets the level of the output signal. The supply voltage to the block 17 is supplied through the zero control unit 16 from the power supply 15. The zero control unit 16 ensures that the signal level forming unit 17 is switched on only when the amplitude regulator 4 of the output voltage is set to minimum. This protects the patient from applying the maximum voltage to the treatment electrodes 8 at the time of switching on to avoid unexpected effects. From the output of the output stage 14, the generated signal is fed to the output transformer 18, which ensures coordination and final formation of the output signal in the form of a sequence of packs of bipolar pulses of 7 ms duration with a repetition rate of 10-50 Hz and a filling frequency of 1.2 kHz, which are fed to the treatment electrodes 8.

Electrical stimulator-analgesic works as follows. The generator 10 generates bipolar excitation pulses, which are formed in packs. The bipolarity of the shape of the excitation pulses with a total pulse component equal to zero excludes the possibility of the formation of electrolysis products on sub-electron spacers, the accumulation of unipolar ions, especially hydrogen and hydroxide ions, near semi-impermeable membranes. The exclusion of this kind of galvanic effects provides a gentle current effect and, therefore, good tolerance of the procedure.

The bursts of pulses are fed to the output of the electric stimulator, to which a cable 9 is connected, connected to the passive and active electrodes 8, mounted respectively on the wrist (passive) and on the impact area (active). Cable 9 can also be connected simultaneously with two active electrodes 8. When the electrostimulator is initially turned on, the output voltage level and the frequency of the bursts of excitation pulses are manually set to the minimum values: the output voltage level is 0 V, the frequency is 0.7 Hz. Then

according to the selected exposure methodology, the required voltage amplitude and frequency are selected and set.

When anesthetizing, the bursts of pulses delivered to the electrodes 8 stimulate pain relief mechanisms by blocking the transmission of pain impulses along nerve fibers and activating the release of pain medications, as well as improving blood circulation in the stimulated area of the body.

Near the frequency controller 3 is a voltage amplitude controller 4.
