Description

The invention relates to medical equipment, namely, devices for implementing a comprehensive therapeutic effect: magnetotherapy or magnetotherapy and hyperthermia for the treatment of rhinolaryngological inflammatory processes, and can be used, for example, in the treatment of the nasal cavity, paranasal sinuses of the nasal cavity - maxillary and frontal sinuses, larynx both in a hospital and at home using the device by the patient.

A known method of physiotherapeutic effects on body tissues for the treatment of inflammatory processes, based on the use of hyperthermia in the temperature range from 30 ° C to 45 ° C (see RF patent No. 1787027, MKI A61F 7/00, publ. 1993).

Known methods of physiotherapeutic effects on body tissues for the treatment of inflammatory processes, based on the use of low-frequency magnetotherapy with an alternating field with magnetic induction of 10-100 mT at a frequency of 2.5 Hz or up to 50 mT (apparatus Pole-1, Pole-2) at a frequency of 50 Hz or up to 40 mT at frequencies of 25-50-75-100-150 Hz (see A.A. Ushakov "Guide to Practical Physiotherapy". - Moscow, ANMI LLP, 1996, p.65, 67-68).

The general disadvantage of analogues with one type of physiotherapeutic effect, including magnetotherapy or hyperthermia, is in reducing the effectiveness of the treatment of inflammatory processes due to the rapid addiction of the body to the effect and a narrow scope in medical practice.

A known method of physiotherapeutic exposure for the treatment of rhinolaryngological diseases, implementing a sequence of exposure modes, including a physiotherapeutic exposure to hyperthermia in the temperature range from 30 ° C to 45 ° C, a physiotherapeutic exposure to magnetotherapy and a simultaneous physiotherapeutic exposure to hyperthermia and magnetotherapy, and in these modes magnetotherapy carried out with a periodically changing frequency from the frequency range from 1 Hz to 2 00 Hz and, accordingly, with magnetic induction amplitudes of 1 mT to 50 mT (see RF patent No. 2209095, MKI A61N 1/40, A61N2 / 02, publ. 2003 - prototype).

The physiotherapeutic effect of hyperthermia provides for treatment at a given constant temperature from a range of 30-40 ° C.

The disadvantage of this method is in the addiction of the body to constant values of the parameters of hyperthermia, which reduces the effectiveness of the treatment.

Known heating pad for therapeutic purposes, containing two heating plates interconnected by an elastic element, and the heating elements are made in the form of a control wire winding on a supporting element and are located in heating plate bodies made of uniform plastic (polyethylene or plastic compound) having corrugations surfaces facing the communication elements, and the communication element is made in the form of a split ring (see RF patent No. 1787027, MKI A61F 7/00, publ. 1993).

Such a device provides only thermal therapeutic effect. This limits the possibility of selecting treatment regimens for diseases, taking into account the individual tolerability of the procedures by patients.

A device for physiotherapeutic exposure for the treatment of rhinolaryngological diseases is known, which contains two plates of physiotherapeutic exposure, interconnected by an elastic coupling element and having a body made of plastic mass, tightly fitting the physiotherapeutic influences located therein, connected through a current lead element to an electrical power unit, and physiotherapeutic impact sources made in the form of thermomagnetic elements, which are installed in h on the magnetic circuit of the coil with a control wire, and are located in the body of the plates of the physiotherapeutic effect with the possibility of creating a magnetic field closed in the direction to the flat working surface of the plates (see RF patent No. 2209095, MKI A61N 1/40, A61N 2/02, publ. 2003 g. - prototype).

In the known device, the magnetic field generated on the thermomagnetic elements has a low depth of exposure, the unidirectionality of the magnetic field on the plane of the working surface of the plates of the physiotherapeutic effect is not ensured. The complexity of the design creates difficulties in technical implementation.

The technical result of the invention of the method is to further increase the effectiveness of the therapeutic effect by increasing the depth of the physiotherapeutic effect for all its modes, while at the same time it is possible to change the temperature parameters of hyperthermia during the treatment procedure, which reduces the body’s degree of addiction to medical procedures.

The technical result of the invention of the device is to simplify its design, which reduces the cost of its manufacture, and increase therapeutic efficiency by increasing the penetration depth of the thermal and magnetic fields, ensuring the distribution of a unidirectional magnetic field over the working surface of the plates of physiotherapy in a given range of values of magnetic induction.

The technical result of the method is achieved by the fact that in the method of treating rhinolaryngological diseases, implementing a sequence of exposure modes, including a physiotherapeutic exposure to magnetotherapy and / or a simultaneous exposure to hyperthermia and magnetotherapy with values of magnetic induction from 30 mT to 50 mT, respectively, and a temperature of at least 40 ° C , in all modes, magnetotherapy is carried out by a unidirectional constant magnetic field, and hyperthermia is carried out at temperatures no more than 55 ° С with alternating temperature increase and decrease in the range from 40 to 55 ° С with a gradient of 0.1 ÷ 1 ° С per second.

The technical result of the device is achieved by the fact that in the device of physiotherapeutic action for the treatment of rhinolaryngological diseases, containing two plates of physiotherapeutic effect, interconnected by an elastic communication element and having a housing made of plastic mass, tightly fitting the magnetic field sources located in it and heating wires connected through the element a current lead with an electric power unit, configured to intermittently interrupt a voltage supply during heating lead wires, heating wires are made of nichrome, magnetic field sources are permanent magnets covered by turns of heating wires, and the electrical power unit contains a voltage converter, the first output of which is connected to the input of the processor, the output of which is connected to the first input of the switch, the voltage converter is connected to the second the output with the second input of the switch, the output of which is the output of the electric power unit for connecting to the heating wires.

Preferably, in the plates of the physiotherapeutic effect, the heating wires are 1.2 meters long with a diameter of 0.3 millimeters.

It is advisable to have cylindrical magnetic field sources.

It is preferable to arrange the turns of the heating wires at a distance of 1 ÷ 3 mm from the working surfaces of the plates, and the distance between the turns of the heating conductor is (0.3 ÷ 1.0) d, where d is the diameter of the magnetic field source.

It is advisable in the plates of physiotherapeutic influence the distance between the turns of the heating wire to have 1 ÷ 3 millimeters.

It is preferable to arrange from one to three sources of magnetic field in each plate of the physiotherapeutic effect, which are installed with the possibility of creating a unidirectional magnetic field to the working surface of the plates of the physiotherapeutic effect.

It is advisable to choose the overall dimensions of the plates of the physiotherapeutic effect and the sources of the magnetic field from the ratios:

L / (d1 + ... + dn) = C / (d1 + ... + dn) = 2 ÷ 6 and Н = (2 ÷ 4) h,

where L, C, H - overall dimensions (respectively length, height and width) of the plates of physiotherapeutic influence;

d and h are the overall dimensions (respectively, diameter and height) of the magnetic field source;

n is the number of magnetic field sources in the plate of the physiotherapeutic effect.

The analysis of the prior art, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allows us to establish that the applicant has not found technical solutions characterized by features identical to all the essential features of the claimed invention. The definition from the list of identified analogues of the prototype made it possible to identify a set of essential (with respect to the technical result perceived by the applicant) distinctive features in the claimed object set forth in the claims. Therefore, the claimed invention meets the requirement of "novelty" under applicable law. Information about the fame of the distinguishing features in the totality of the characteristics of the known technical solutions with the achievement of the same as the claimed device, there is no positive effect. Based on this, it was concluded that the proposed technical solution meets the criterion of "inventive step".

Figure 1 shows a physiotherapeutic device for the treatment of rhinolaryngological diseases (top view); figure 2 shows a plate of physiotherapy with one element of a constant magnetic field (front view); figure 3 shows a plate of physiotherapy with three elements of a constant magnetic field.

Figure 4 presents a structural diagram of an electric power unit that provides a controlled supply of voltage to the heating wires of the plates of physiotherapeutic effects.

Physiotherapeutic effect for the treatment of rhinolaryngological diseases using the proposed device is as follows. The doctor determines the course of treatment for a particular patient, including a given number of procedures and their duration from the list of modes that the device provides:

- simultaneous exposure to magnetotherapy and hyperthermia;

- exposure to magnetotherapy.

Moreover, in these modes, magnetotherapy is carried out at values of the magnetic induction amplitude from 30 mT to 50 mT, and hyperthermia at temperatures from 40 ° C to 55 ° C with alternating temperature increases and decreases in the range from 40 ° C to 55 ° C with a gradient 0.1 ÷ 1 ° C per second. The extreme values of the magnetic induction range are limited by medical recommendations (A.A. Ushakov, “Modern Physiotherapy in Clinical Practice”, ANMI, Moscow, 2002, p. 74). The upper limit of the temperature range (55 ° C) is selected from medical methods of heat therapy using medical paraffin, the melting point of which is 52 ÷ 55 ° C. Treatment at temperatures less than 40 ° C has low efficiency, while a longer exit to more effective upper temperatures in the hyperthermia range lengthens the treatment procedure. Permanent magnets, providing a unidirectional positive magnetic field, and periodic short-term (no more than 10 seconds) physiotherapeutic effects of hyperthermia at a temperature higher than in the prototype, 55 ° C, can significantly increase the therapeutic effect due to the deeper effects of magnetotherapy and hyperthermia.

The course of treatment with magnetotherapy and hyperthermia can be carried out for 15 days during daily procedures for 15-20 minutes.

The course of treatment, in particular sinusitis, magnetotherapy can be carried out for 30-40 minutes for 10-20 procedures. The procedures are carried out 4-6 times a week.

A physiotherapeutic device for the treatment of rhinolaryngological diseases contains two plates 1, 2 of a physiotherapeutic effect (magnetotherapy or at the same time hyperthermia and magnetotherapy), interconnected by an elastic connection element 3 and having a body made of plastic material, tightly fitting the magnetic field sources 4 and heating wires located in it 5, connected through a current input element 6 to an electric power supply unit 7 configured to periodically interrupt tension on the heating wires 5 during the treatment procedure.

In the plates 1, 2 of the physiotherapeutic effect, the heating wires 5 are made of a material with high resistivity (for example, nichrome) 1.2 meters long and have a diameter of 0.3 mm. The turns of the heating wires 5 are located at a distance of (l) 1 ÷ 3 millimeters from the working surfaces of the 8 plates 1, 2 of physiotherapeutic influence, and the distance (b) between the turns of the heating conductor is (0.3 ÷ 1.0) d, where d is the diameter magnetic field source. The distance (b) between the turns of the heating wire is 1 ÷ 3 millimeters.

Sources 4 of the magnetic field are permanent magnets of a cylindrical shape and are covered by turns of heating wires 5. In each plate 1, 2 of a physiotherapeutic action, there are from one to three sources 4 of a magnetic field installed with the possibility of creating a unidirectional magnetic field with magnetic induction from 30 mT to 50 MT to the working surface of 8 plates 1, 2 physiotherapeutic effects. Moreover, to improve the effectiveness of treatment, the same name, preferably positive poles of these sources 4 should be facing the working surface 8 of the plates 1, 2 of physiotherapeutic effects. As sources 4 of the magnetic field, permanent cylindrical magnets are used, for example, of barium ferrite, which provide a magnetic field distribution with magnetic induction of 30-50 mT on the working surface of 8 plates 1, 2 of physiotherapeutic effect. Permanent magnets can be located in the central part of these plates 1, 2 (Fig. 2) or in a row, for example, along the diagonal of plates 1, 2 (Fig. 3) or in another way (in a spiral, circle - not shown in Fig.) . The diameters of the permanent magnets in the plates 1, 2 can be the same (Fig. 1, 2) or different (in Fig. Not shown).

The overall dimensions of the plates 1, 2 of the physiotherapeutic effect and sources 4 of the magnetic field are selected from the ratios

L / (d1 + ... + dn) = C / (d1 + ... + dn) = 2 ÷ 6 and

N = (2 ÷ 4) h,

where L, C, H - overall dimensions (respectively length, height and width) of the plates of physiotherapeutic influence;

d and h are the overall dimensions (respectively, diameter and height) of the magnetic field source;

n is the number of magnetic field sources in the plate of the physiotherapeutic effect.

The electric power supply unit 7 comprises a voltage converter 9, the first output of which is connected to the input of the processor 10, the output of which is connected to the first input of the switch 11, the voltage converter 9 being connected by the second output to the second input of the switch 11, the output of which is the output of the electric power supply unit 7 to the heating wires of 5 physiotherapeutic plates 1, 2. The electric power supply unit 7 provides a controlled supply of voltage to the heating wires of 5 plates of 1, 2 physiotherapeutic th exposure. The switch 11 is, for example, a key enable transistor. The voltage Converter 9 converts the high voltage input voltage to a safe low voltage. The voltage from the first output of the converter is intended for stabilized power supply of the processor 10, and the voltage from the second output is used to power the heating wire 5 through the switch 11. The processor 10 provides a control signal at the input of the switch 11, which provides intermittent supply (switching) of voltage from the converter 9 to the heating wires 5 plates 1, 2 physiotherapeutic effects.

The device is used as follows. Spreading the plates 1, 2 of the physiotherapeutic effect due to the deformation of the elastic element 3, set them on the impact area (nasal cavity, maxillary sinuses). Moreover, these plates 1, 2 tightly, the entire working area should be adjacent to the skin on the affected area.

The physiotherapeutic device for the treatment of rhinolaryngological diseases works as follows.

When you turn on the block 7 of the electric power in the mains voltage is supplied to the voltage Converter 9. In this case, the processor 10 generates a voltage pulse at the output, opening the switch 11. The switch 11 transfers the voltage from the second output of the converter 7 (through its second input) to the heating wires 5 of the plates 1, 2 of the physiotherapeutic effect. The heating wires 5 are heated, while the working surface 8 of the indicated plates 1, 2 is heated to a temperature not exceeding 55 ° C. After that, the processor 10 turns off the voltage pulse controlling the switch 11, and the switch 11 is closed. When heat is transferred from the working surface of 8 plates 1, 2 of a physiotherapeutic effect to the patient’s tissue through his skin, the temperature of the working surface 8 drops to a value not lower than 40 ° C. After that, the operation of the processor 10 is repeated. Moreover, the change in temperature values of the working surface 8 in the range from 40 ° C to 55 ° C occurs with a gradient from 0.1 ° C / s to 1 ° C / s. Unidirectional magnetic field and periodic short-term (no more than 10 seconds) physiotherapeutic effects of hyperthermia at a temperature of 55 ° C allow painless treatment procedures to be carried out with a significant increase in the effectiveness of treatment and reduce treatment time.

The simplicity of design and operation, portability and low cost make it possible to use the device as a home physiotherapeutic apparatus, as well as in the field.

The inventive device provides an increase in the effectiveness of treatment of rhinolaryngological diseases due to a deeper penetration of unipolar magnetic effects into tissues limited by the area of influence, and reduction of the negative effect of the body’s addiction to physiotherapeutic procedures. The proposed device is simple, convenient and hygienic in use, has an increased degree of security, provides ease of disinfection. The simplicity of design and low cost of assembly can reduce the price of the product, which opens up a wide prospect of using the device by a large circle of the population.
