Description

 The invention relates to medicine, namely to electrotherapeutic devices operating according to the Darsonval method, that is, creating an effect on the patient with an alternating pulsed high-frequency current of high voltage and low power. The proposed device can be widely used in physiotherapy and cosmetology.

 Known devices for local darsonvalization (see, for example, copyright certificates [1] [2]), each of which contains a related treatment electrode, shock excitation circuit, rheostat and power source.

 Known devices do not provide an effective therapeutic effect, since the effect is carried out at each moment of time at only one point and when moving the electrode is a sequence of points that can be represented as a broken line.

 In addition, the known devices are unsafe in operation, since the electrode is made in the form of a glass tube with reduced pressure inside. In these devices, additional energy is spent on ionizing the gas in the electrode to bring the gas into a conductive state.

 Known electromassage device [3] which provides not only combing hair, but also the effect on the skin of the head with asymmetric current pulses. This device contains a battery, a pulse generator and conductive teeth.

 The known device does not have the ability to provide a therapeutic effect according to the Darsonval method.

 Closest to the proposed device (prototype) is a device for darsonvalization [4] containing a power supply connected to a high voltage generator, and an electrode.

 However, the known device does not provide an effective therapeutic effect, since the effect is carried out at each moment of time only at one point where an electric discharge occurred (the path of least resistance to current), and when moving the electrode is a sequence of points that can be represented as a broken line.

 In addition, the known device is unsafe in operation, since the electrode is made in the form of a glass tube with reduced pressure inside. This device additionally consumes energy to ionize the gas in the electrode to bring the gas into a conductive state.

 The task that the invention solves is to expand the arsenal of technical means for darsonvalization by developing a new device for implementing the treatment method according to Darsonval.

The following technical results are achieved:
increasing the effectiveness of therapeutic effects by increasing the field of exposure;
reduction of energy consumed by the amount of energy needed to ionize the gas in the electrode;
improving the safety of operation of the device by eliminating the thin-walled glass electrode with reduced pressure inside.

 These technical results are achieved by the fact that in the device for darsonvalization containing a power supply, the first output of which is connected to the first input of the high voltage generator, and an electrode consisting of an insulating material and a conductive element, a high-voltage switch, a control unit are additionally introduced, and additionally, conductive elements introduced. In this case, the conductive elements are electrically connected to the outputs of the switch, and its first input is connected to the output of the high voltage generator. The second input of the switch is connected to the first output of the control unit, the second output of which is connected to the second input of the high voltage generator. The input of the control unit is connected to the second output of the power supply.

 Improving the effectiveness of the therapeutic effect is provided due to the fact that the trajectory of the impact for one longitudinal movement of the electrode along the patient’s body is no longer a line (as in the prototype), but some set of lines (according to the number of conductors in the electrode), because the voltage on the conductive elements ( and consequently, the arising electric discharges) are switched with a considerable frequency.

 To operate the device requires less energy, since the conductive elements are already in the conductive state and they need to be brought into this state, as is done in the prototype, where it is necessary to ionize the gas.

 In addition, increases the safety of operation of the device by eliminating a thin-walled glass electrode with reduced pressure inside.

 Comparison with similar technical solutions known from publicly available sources of information shows that the claimed technical solution contains a new set of distinctive features unknown from the prior art, therefore, the claimed solution meets the criterion of "novelty."

 Distinctive features themselves are known from other technical solutions (see, for example, Aut. St. USSR N 1813002, publ. 04/30/93 A61N 1/32, Russian patent N 2014068, publ. 06/15/94 A61H 39 / 08).

 However, in contrast to the well-known technical solutions, the claimed solution of the set technical result, namely, increasing the effectiveness of the therapeutic effect, can be achieved only by using a high-voltage switch, and not any other. In addition, well-known solutions achieve completely different technical results. It should also be noted that a new, physiotherapeutic tool is proposed that expands the arsenal of devices for darsonvalization.

 From this we can conclude that the causal relationship between the totality of the claimed distinctive features and achievable technical results is unknown from the prior art, which proves the conformity of the proposed solution to the criterion of "inventive step".

The inventive device for darsonvalization is illustrated by drawings, where:
in FIG. 1 shows a functional diagram of a device;
in FIG. 2 presents one of the variants of the circuit diagram of the device;
in FIG. 3 schematically shows the field of therapeutic effect in the prototype (see Fig. 3a) and in the claimed technical solution (see Fig. 3b).

 The inventive device for darsonvalization (see Fig. 1) contains a serially connected power supply 1, a high voltage generator 2, a high voltage switch 3, as well as a control unit 4 and an electrode 5. The electrode 5 consists of conductive elements 6 and an insulating material 7. The input of the unit control 4 is connected to the second output of the power supply 1, and the first output of control 4 is connected to the second input of the switch 3. The second output of the control 4 is connected to the second input of the high voltage generator 2. The outputs of the high voltage switch Ora 3 are connected to conductive elements 6 of electrode 5.

 The power supply 1 (see Fig. 2) contains a transformer 3, semiconductor rectifier diodes 9, 10, a capacitor 11 and provides the outputs: the voltage of the high voltage generator 2 and the control voltage of the high voltage switch 3.

 The high voltage generator 2 (see Fig. 2) contains a charging resistor 12, a charging capacitor 13, a dynistor (threshold key element) 14, a high voltage transformer 15, a capacitor 16 and provides a high AC voltage required for the implementation of Darsonval treatment and supplied to the high voltage switch 3.

 The high-voltage switch 3 (see Fig. 2) contains a DC motor 17, on the shaft of which a dielectric disk 18, for example of fiberglass, with a conductive ring track 19, for example, of copper foil placed around the perimeter on one side of the disk, is rigidly fixed. A high voltage is supplied to the ring track through a sliding contact 20. A distribution element 21 is installed on this track, through which the high voltage current is switched to the fixed elements 22 of the switch 3 located on another dielectric disk 23 and electrically connected to the conductive elements 6 of the electrode 5.

 The control unit 4 (see Fig. 2) contains a variable resistor 24 for controlling the amplitude of the high voltage and a variable resistor 25 for controlling the engine speed of the switch 3.

 The electrode 5 can be made of any desired shape, for example mushroom-shaped (see Fig. 1), or in the form of a comb (see Fig. 2). An example of the construction of the output of the conductive element is shown in FIG. 2a. As the insulating material of the electrode, for example, polycarbonate, polystyrene, plexiglass can be used, and the conductive elements can be made of stainless steel wire.

 The functional elements of the claimed device may have other various forms of implementation.

 The inventive device operates as follows. When you turn on the device for darsonvalization (for example, in the network), the power supply 1 generates the necessary supply voltage for all nodes of the device. In this case, the high voltage generator 2 generates a pulsed alternating high voltage of a given shape and amplitude, which is supplied to the switch 3. The control unit 4 controls the frequency of the voltage switching via the variable resistor 25, and also controls the high voltage amplitude by the variable resistor 24. The switch 3 distributes the voltage along the conductive elements 6 of the electrode 5. When the electrode moves through the patient’s body, electrical discharges occur between the conductive elements and the patient’s body.

 During treatment, when the electrode moves through the patient’s body, the path of exposure for one movement of the electrode is no longer a line, as in the prototype (see Fig. 3a), but some set of lines (see Fig. 3b) according to the number of conductive elements in the electrode, because the voltage on the conductive elements (and therefore the resulting electrical discharges) is switched with a significant frequency. The communication frequency is chosen so that for a small displacement Δl along the surface, discharges occur at least 1 time on all conductive elements of the electrode. Thus, the coverage area (field of therapeutic effect) increases and thereby the effectiveness of therapeutic effect. The session time can be proportionally reduced due to the decrease in the number of longitudinal movements of the electrode, thereby reducing the load on the medical staff, and at the same time, the energy consumption is also reduced.
