Description

Description of the invention

The device belongs to medicine and can be used for physiotherapeutic treatment of patients suffering from cold, inflammatory, skin and other diseases who have suffered mechanical, thermal and other body injuries.

The proposed device uses a high intensity electric field, negative charges, the effect of electroacupuncture, broadband pulsed radio radiation as therapeutic factors.

The well-known device AF-3 ("Techniques and methods of physiotherapeutic procedures" Handbook. 3.S. Kuleshova, 70 v. Yasnogorsky, O.I. Epifanov et al. Edited by V.M. Bogolyubov. M., "Medicine", 1983, page 195), containing a high-voltage direct current source of negative polarity, to which a needle electrode, a hinged holder and a spark arrestor, which acts as a second grounded electrode, are connected to it by a high-voltage wire.

Disadvantages of the analogue are: 19 - placement of the hinged holder with the needle electrode above the surface of the patient's body, which has a large curvature (for example, the leg), which creates an uneven effect of the electric field and negative charges on the patient's body area. This reduces the effectiveness of the treatment process and limits the mobility of the patient's body during the entire treatment process; - the presence of an air gap requires high voltage during the treatment process from 10 to 25 kV, reduces the efficiency of the device due to the dispersion of aeroions in the surrounding space.

The closest in terms of technical essence and the results achieved is the device |Application Mo a200508130 "Vorontsov's device for physiotherapeutic treatment by local contact influence with a negative potential of high values"!), which contains a high-voltage source of direct current of negative polarity, to which a high-voltage flexible insulated loose wire connected needle electrode containing one 29 mm needle, made in the form of a tip with a dielectric body, while the needle electrode is placed -o in an insulated screen that conducts current, and in the middle of the dielectric body of the tip there is an electrical or mechanical switch, connected in series with a needle electrode and a high voltage flexible insulated loose wire.

The disadvantage of the prototype is: o 30 - the inverse dependence of the charge and discharge currents of the patient during treatment on the resistance of the environment, "And that, in turn, is inversely proportional to the relative humidity of the surrounding air. At values of the relative humidity of the air, the charge and discharge currents can be up to several hundreds of kA, which is safe, but makes the treatment process painful;

Zo - painful sensitivity of patients can vary significantly. Therefore, treatment regimens for one patient may be intolerable for another, and even when switching the device to the weakest treatment regimen, it may be insufficient for the normal treatment process.

The basis of a useful model is the task of increasing the efficiency of the device and improving its operational capabilities under local influence. 40 The set task is achieved by the fact that Vorontsov's device for physiotherapeutic treatment with a local c) contact effect with a negative potential of high values, containing a high-voltage source of constant "" current of negative polarity, to which a needle electrode containing one or M needle, made in the form of a tip with a dielectric body, in which the needle electrode is placed in an insulated screen that conducts current, and in the middle 45 of the dielectric body of the tip, an electrical or mechanical switch is placed, connected in series with the needle electrode and a high-voltage flexible insulated loose wire, high-voltage source

The GI of the current of negative polarity is additionally equipped with a toggle switch and a socket connected to its positive pole, at the same time, the free end of the toggle switch is connected to the contact of the grounding mains plug, and a parallel-connected resistor and a switch are introduced into the dielectric housing of the tip, which connected in series with their existing 20 electric or mechanical switch and high-voltage insulated loose wire.

The cause-and-effect relationship between the set of declared signs and the technical result is as follows.

Due to the fact that the high-voltage current source of negative polarity is additionally equipped with a toggle switch and a socket connected to its positive pole, at the same time, the free end of the toggle switch is connected to the grounding contact of the mains plug, and in the dielectric housing of the tip, parallel connected resistors are introduced and a switch connected in series with an existing electric or mechanical switch and a high-voltage insulated loose wire increases the efficiency of the device, expands the range of its use, and improves its operational capabilities under local influence.

The Vorontsov device for physiotherapeutic treatment by contact exposure with a negative potential of high values contains a high-voltage source of direct current 1 of negative polarity, to the negative pole of which a needle electrode 3 containing one or M needles, made in the form of a tip with a dielectric body 4, is connected by a high-voltage flexible insulated loose wire 2 The tip contains an insulated screen 5 located around the needle electrode 3. The high-voltage direct current source 1 of negative polarity contains a mains plug 6 having a grounding contact 7 and a mains cord 8 having three wires 70, one of which is connected to grounding contact 7 and one of the contacts of the toggle switch 9. The second contact of the toggle switch 9 and socket 10 are connected to the positive pole of the high-voltage direct current source 1 of negative polarity. A pin 11 connected by an electric wire 12 and an alligator clip 13 is included in the socket 10.

Socket 10 and pin 11 form a mechanical switch. The high-voltage direct current source 1 of negative polarity contains the mode switch 14.

In variants 1 and 2 (Fig. 2 and Fig. 3), which differ in the number of needles, two switches 15 and 20 are located in the dielectric housing 4 of the tip, which can be electrical or mechanical. The switch 15 is connected in series with the needle electrode C and with one end of the switch 20, the other end of which is connected by an insulated wire 17 to a high-voltage flexible insulated loose wire 2. A resistor 16 is connected in parallel with the switch using an insulated wire 17. 20 In version C ( Fig. 4) needle electrode C is made in the form of a movable contact. The spring 18 is designed to return the needle electrode C to its original state. In the dielectric housing 4, there is a fixed contact 19, electrically connected to an electric or mechanical switch 20. The connection of the switch 20 to the resistor 16 and the high-voltage flexible insulated loose wire 2 is similar to that shown in Fig.

Fig.2 and Fig.3.

Vorontsov's device for physiotherapeutic treatment by local contact exposure with a negative potential of high values works as follows. but)

A high-voltage direct current source 1 of negative polarity is connected to the power source by means of a mains plug b with grounding contact 7 and a mains cord 8, which is set to the minimum voltage mode using the mode switch 14. The switch 9 is set before the start of the treatment ("From to position In the absence of an energy source with a grounded wire (for example, there is no "euro-socket"), the grounding of the source 1 of direct current of negative polarity is carried out through the socket 10, into which the pin 11 is connected, electrically connected to the wire 12 and the "crocodile" type clamp " 13, which is connected to the external grounding loop. Before starting the treatment, the pin 11 is also disconnected, the switches 15 and 20 on the dielectric housing 4 of the tip are turned off.

When supplying voltage from the high-voltage source 1 of direct current of negative polarity, the corresponding voltage appears on the electrical switch 15. When the switch 15 is turned on, the necessary voltage appears on one or M needles of the needle electrode Z. An ungrounded patient, touching the needle electrode Z with a finger, receives an electric charge (charges), while a tingling sensation is felt. The electrical scheme "equivalent to the process of treating a patient with the toggle switch 9 turned off and K dod turned on (at the same time, the switch 20 is turned off) is shown in Fig.b. - s Here: K, - internal resistance of high-voltage source 1 direct current of negative polarity. The safe value of the current for a person is less than 1 tA. At a current value of 0.4 tA (as in the AF-3 device) and "» voltage less than or equal to 1Okv, 10407 5 Kh-tr - g31MOmM t 04073 ime) S. - electrical self-capacitance of the needle electrode 3. with Se -th pF . their 50 Kdod is an additional resistor. Kdod 2 5 Mohm (chosen constructively). This resistance is comparable in magnitude - with Ki limits the current Izar. dis. at the first touching of the patient with the needle electrode C and the next treatment.

Izar - charge current of the electric capacity of the patient Shch.

Iroz. - discharge current of the patient's electric capacity through the environment (K avk 1).

Edil - resistance of the part of the patient's body that is subject to medical treatment. This resistor depends on the age of the patient, the location of the body part during treatment, the contamination of the skin surface, the temperature of the environment and the patient's perspiration and varies widely. Approximately Kdil, 7 20-1000 kΩ;

S. - electrical capacity of the human body. In the first approximation, C is proportional to the surface area of the patient's skin. Su. - 50-300 pF. Obviously, C depends on the age of the patient (increases with age). Kuavk1 - the resistance of the air 60 environment surrounding the patient's body during treatment. It depends on the relative humidity of the air, the surface area of the patient's body and the temperature of the environment. At the moment of the first touching of the patient with the needle electrode Z, the total current Izar/"IrozIzar" flows through the patient's Kdid, charges the capacity Сh for less than 1 second and drops to 0. Further through the KDD, during the treatment, only the discharge current Iroz., which has the maximum calculated the value is less than 1 rkA. Hence Tst"tah 105 16 .

An increase in the values of relative humidity and air temperature and an increase in the surface area of the skin reduces K,avk1, and a decrease in these factors increases K,avk1.

Therefore, when the toggle switch 9 and the switch 20 on the dielectric body 4 of the tip are in the "OFF" position. 70 significantly decreases the charge current І gar. when touching the patient with the electrode Z of the tip (by more than 10 times) and by more than 2 times, the discharge current of the 1st division decreases. This significantly reduces the degree of tingling of the patient during treatment and makes the treatment process easily bearable, which is important when the value of Kuavki resistance is low (at high temperature and relative humidity of the air around the patient, with a large surface area of the patient's skin). According to the degree of tingling, which should be easily tolerated by the patient, the necessary therapeutic voltage is set with the switch 14 ""EJHIMYI" 79. If the tingling is slight or not felt even at the maximum mode, the switch 14 "NON-PRESSED!" is set to the position corresponding to the minimum value therapeutic voltage, the toggle switch 9 and the switch 20 on the dielectric housing 4 of the tip is set to the "ON" position. This case corresponds to the maximum value of K,avki at a low value of relative humidity ("dry air") and moderate air temperature, a small surface of the patient's skin. The electrical circuit equivalent to the patient treatment process when "1" is turned on (the toggle switch "I" 9 is in the "ON" position and the shunted Kdop resistor (the position of the switch 20 is also "ON") is shown in Fig. 5. There are no resistors here

Addendum and Knavk"; which significantly increases the value of the currents I charge and Iroz Switch 14 "MODE!" sets the necessary therapeutic voltage. When touched with a needle electrode From the part of the body of an ungrounded patient that is subject to therapeutic influence, under the action of a strong electric field, negative charges (electrons) penetrate through the corneal epithelium skin into the middle of the patient's body, creating a therapeutic effect. When treating hard-to-reach areas of the patient's body that have high electrical conductivity (for example, the oral cavity), the electrical or mechanical switch 15 on the dielectric body 4 of the tip is first turned off. Then, touching the treatment site with a needle electrode, the electrical or mechanical switch 15 is turned on and the time-dosed therapeutic effect is carried out by moving the needle electrode C within the treatment zone. "I

Because the horny epithelium of the skin in normal places has different resistance in different areas, negative charges are directed inside the patient's body in the form of electric current pulses, creating an additional effect of electroacupuncture. This phenomenon is accompanied by sparking and charging crackle. At the same time, broadband pulsed radio radiation is generated, which also creates an additional therapeutic effect. Parasitic radio radiation into the surrounding space is absorbed by the insulated screen 5 of the tip, made, for example, in the form of a metal cup with a hole in the bottom, which creates an almost closed shielded volume, since on one side there is an insulated screen 5 that conducts current, which absorbs radio radiation, and on the other hand, the patient's body, which also absorbs radio radiation. The insulated screen 5 can be made in the form of a separate metal part that is put on the dielectric housing 4, or in the form of metallization of its part in which the needle electrode 3 is located. The screen 5 is insulated from the outside to avoid accidental failure of the patient who is during treatment under high potential, and the attending physician. z" In variant Z, the tip is designed for a precisely dosed therapeutic effect (for example, for the treatment of a diseased tooth or aphthae). At the same time, the movable needle electrode C is installed in the treatment area. When the needle electrode C is lightly pressed, the spring 18 is compressed and it touches the fixed electrode 19, electrically connected through a resistor 16 or a switch 20 to a high-voltage flexible insulated wire 2, while the necessary therapeutic voltage is supplied to the treatment area for the required time . At the end of the procedure, the tip is moved away, while the movable needle electrode C is moved away and returned by the spring 18 to the initial state, interrupting the electrical contact. o The proposed useful model allows you to treat patients with the device regardless of the conditions of the surrounding environment, increase the efficiency of the device and improve its operational capabilities under local influence on patients of any age.
