Description

The present invention relates to the field of medical equipment, more specifically to devices of decimeter and centimeter wave ranges, and can be used in the treatment of pulmonary diseases, inflammatory processes, for the rapid healing and anesthesia of wounds, burn injuries, phlebitis, thrombophlebitis, mastitis, arthritis and arthrosis, radiculitis and other diseases.

A device with an emitter of electromagnetic energy for RF and microwave therapy of abdominal organs, comprising a housing with a coaxial energy input mounted in it and an emitter in the form of a coaxial resonator (Patent RU 2117496 from 01/15/1996, A61N 5/02 [1]). However, the analogue [1] is intended only for the treatment of abdominal organs and cannot be used in the treatment of lungs, liver, pancreas and other isolated organs.

Also known apparatus for therapeutic exposure to microwave electromagnetic energy according to US patent 6026331, published 02.15.2000 [2]. This device is used in gynecology for the treatment of menorrhagia by local exposure (ablation). The device includes a sensor equipped with at least one emitter of microwave energy, and a control circuit. The disadvantage of the device [2] is the narrow purpose and the possibility of its use for only one specific therapeutic task.

A known method of microwave resonance therapy and a device for its implementation according to US patent 5152286 [3], published on 6.10.1992. The device according to this patent contains a generator with an active element, an electromagnetic energy transmission channel, an electromagnetic energy converter, and a radiating antenna. The device affects biologically active zones with high-frequency electromagnetic radiation with a power density of 10 W / cm ² . It is advisable to use the device for patients suffering from disorders of the gastro-duodenal system, chronic lung diseases, disorders of the nervous system and musculoskeletal system. The disadvantage of this device [3] is the narrow scope of its application - only for exposure to reflex zones, which leads to the duration of the procedure and relatively low efficiency.

The closest in design features to the claimed object is a physiotherapeutic apparatus containing a power supply unit, a control panel, a microwave generator, a working signal generating unit including operating frequency generators and a switch, a modulator and a microwave emitter (Patent RU No. 2179465, published 02.20.2002 g. [4]).

The analogue [4] is selected by us as a prototype.

The device [4], although it allows you to selectively affect the biological object with the adaptation of the working signal to a specific object, however, it has low efficiency in the treatment of a wide range of diseases, due to the manual setting of treatment modes and possible errors in information about the diagnosis of the disease.

The aim of the present invention is to increase the effectiveness of treatment by creating a physiotherapeutic apparatus with feedback and automatic selection of the optimal physiotherapy regimen.

The technical result is expressed in the expansion of the arsenate of technical means of physiotherapy by creating a device for diagnosing the disease and automatically selecting the optimal physiotherapy regimen. It is achieved by the fact that the physiotherapeutic apparatus containing a power supply unit, a control panel, a microwave generator, a working signal generating unit including operating frequency generators and a switch, a modulator, a microwave emitter is supplemented with a feedback line containing at least one circuit with an optoelectronic detector, an amplifier, and an analog-to-digital converter connected to a computer, having a video monitor inserted into the control panel, with an additional program for working in the photoplethysmograph mode, containing the data archive atology ”and an electronic comparator that compares the current photoplethysmographic signal with archived data, while the working signal generation unit generates rectangular rectangular positive pulses with a voltage of 3 V and a duration of t = 40 ms, supplied to the modulator with intervals Δt = 43 ms, 120 ms , 290 ms, 380 ms, 520 ms with a cycle time from 8 seconds to 17 minutes, and a microwave coaxial type resonator equipped with a light indicator of the interference zone is used as a microwave energy emitter gain.

Further, the invention is accompanied by drawings and explanations thereto.

In FIG. 1 shows a block diagram of the proposed device, in FIG. 2 shows the waveform of the operating signal; FIG. 3 is a graph of the distribution of the power density of electromagnetic radiation from the working end of the coaxial microwave resonator in the direction of radiation propagation, and FIG. 4 shows the design of a double-beam laser marker.

The physiotherapeutic apparatus contains a power supply unit 1, an apparatus control panel 2, a working signal generating unit 3, including operating frequency generators 4 ₁ , 4 ₂ , 4 ₃ , 4 ₄ , 4 ₅ and a switch 5. The generator 4 ₁ generates rectangular square-shaped electrical pulses of positive sign voltage of 3 V and a duration of t = 40 ms with intervals Δt = 43 ms (Fig. 2). Generator 4 ₂ generates rectangular-shaped electrical pulses of positive sign with a voltage of 3 V and a duration of t = 40 ms with intervals Δt = 120 ms. Generator 4 ₃ generates rectangular rectangular positive electric pulses with a voltage of 3 V and a duration of t = 40 ms with intervals Δt = 290 ms.

Generator 4 ₄ generates rectangular-shaped electrical pulses of positive sign with a voltage of 3 V and a duration of t = 40 ms with intervals Δt = 380 ms. Generator 4 ₅ generates rectangular-shaped electrical pulses of positive sign with a voltage of 3 V and a duration of t = 40 ms with intervals Δt = 520 ms. The inclusion of a generator 4 ₁ , 4 ₂ , 4 ₃ , 4 ₄ , 4 _{5 is} carried out by switch 5 by a signal from the control panel 2. Electric pulses from generators 4 ₁ , 4 ₂ , 4 ₃ , 4 ₄ , 4 ₅ are fed to the modulator 6, which generates a working signal of a microwave energy emitter, which is used as a coaxial type microwave resonator 7, containing internal 8 and external 9 conductors. By adjusting the relative position of the inner 8 and the outer 9 conductors, interference amplification of the coherent wave is achieved at a given depth, for example, in region A of the biological object, (right lung) of patient P located on the treatment table 10 (Fig. 1).

In FIG. 3 interference amplification (region with a high energy density of electromagnetic radiation) A is located at a distance L ₁ from the emitter of microwave energy.

The microwave cavity 7 is mounted in a holder 11 connected to a carriage mounted on a rail located on a tripod (not shown in FIG. 1). The mechanism 12 allows you to move the microwave resonator 7 along the guide. In this case, the position of the interference amplification zone A changes (moves away or approaches). During treatment, the interference amplification zone A (the region with increased electromagnetic energy density) should be “immersed” in the lesion site (target point).

To visualize the interference amplification zone A, a two-beam light (laser) marker 13 is used with a power supply 14 connected to the control panel 2. Its design is shown in FIG. 4. It contains two low-intensity 15 _L and 15 _P lasers emitting in the red range of the visible spectrum. Lasers 15 _L and 15 _{P are} fixed in the end part of the casing 16 of the microwave cavity 7 on the carriages 17 _L and 17 _P , the rotation of which within ± 20 ° can be performed using the adjustment screws 18 _L and 18 _P. An intense red spot 19 appears on the screen installed at the intersection point of the laser beams l _Л and l _П on the optical axis i of the emitter 7. During the alignment of the emitter 7, the light spot 19 is aligned with the interference amplification zone A. The working distance from the emitter 7 to zone A is usually 42-64 cm. The diameter of the interference gain zone A depends on the operating frequency of the microwave cavity.

Under the influence of microwave radiation in the body of patient P, located on the treatment table 20, changes occur that are recorded by a feedback line containing a circuit with an optoelectronic detector 21 mounted on the finger S of patient P, an amplifier 22 and an analog-to-digital converter (ADC) 23 (Fig. 1). The signal from the output of the ADC 23 enters the computer 24, entered into the control panel 2, supplemented by a program for working in photoplethysmograph mode. The computer 24 contains a microprocessor 25, supplemented by a digital norm-pathology data archive 26 and an electronic comparator 27, which compares the current photoplethysmographic signal from the ADC 23 with the archive data stored in the digital archive 26. The resulting signal from the comparator 27 is sent to the microprocessor 25, where after processing according to the appropriate program is displayed on a video monitor 28, equipped with a printer, such as a laser (not shown). The control unit 2 is carried out using the keyboard 29.

The physiotherapy apparatus kit includes 6 microwave resonators that differ in operating frequencies: 2 GHz, 2.5 GHz, 3 GHz, 4.5 GHz, 6 GHz, 10 GHz. The choice and installation of a particular microwave resonator depends on the size of the pathological area. A microwave resonator with a working frequency of 2 GHz creates a region with an increased energy density of electromagnetic radiation with a diameter of 15 cm, with 2.5 GHz - 12 cm, with 3 GHz - 10 cm, with 4.5 GHz - 7.5 cm, and with 6 GHz - 5 cm, and with 10 GHz - 3 cm.

We will demonstrate the method of using the physiotherapeutic apparatus using the example of treatment of patient N. with the disease of pneumonia of the right lung, detected by radiography. The analysis of x-rays made it possible to clarify the size and location of the lesion. The size of the inflammatory zone was 7 cm in diameter with the pathology located in the upper lobe of the right lung. Therefore, a microwave resonator with an operating frequency of 4.5 GHz was selected, which creates a region with an increased energy density of electromagnetic radiation with a diameter of 7.5 cm. After attaching the microwave resonator to a tripod and connecting to the corresponding blocks of the physiotherapy apparatus, it was tuned using a laser marker 13 by the method described above. When laying the patient on the treatment table 20 sought to ensure that the lesion was aligned with the area of interference amplification A (Fig. 1). Next, an optoelectronic detector 21 was attached to the patient’s finger, connected to an amplifier 22 and an ADC 23 connected to a computer 24. Using the keyboard 29, the doctor enters the patient information and a command to connect the corresponding program according to the disease profile to the computer 24.

The photoplethysmographic signal from the patient is removed twice, first when exposed to the body with electromagnetic pulses of the microwave range (4.5 GHz), a rectangular shape of a positive sign with a voltage of 3 V and a duration of t = 40 ms with intervals Δt = 43 ms, 120 ms, 290 ms, 380 ms, 520 ms with a cycle time of 30 seconds. Secondarily, photoplethysmography is performed with the microwave cavity turned off. Double signal removal allows you to get respectively the working and background values of the desired values, the difference of which is compared by the electronic comparator 27 with the normal values stored in the digital data archive 26.

The results of comparing are sent to microprocessor 25, which determines the optimal mode of microwave therapy and ensures its implementation.

The creation of a physiotherapeutic apparatus of the microwave range, equipped with an electronic system for testing the functional state of the body with feedback and automatic selection of the optimal physiotherapy regimen, makes it possible to increase the effectiveness of physiotherapeutic treatment. The proposed device can be widely used in the treatment of pulmonary diseases, inflammatory processes, for the rapid healing and anesthesia of wounds, burn injuries, phlebitis, mastitis, arthritis and arthrosis, radiculitis and other diseases in polyclinics and general clinics and specialized medical institutions.
