Description

The inventive utility model relates to medical equipment, namely to phototherapeutic devices for the treatment of diseases, mainly the oral cavity, larynx and nasopharynx.

RU patents for phototherapeutic devices using exposure to light radiation are known.

[No. 2286186] - “A device for irradiation with light of the larynx and oral mucosa in children”;

[No. 63690] - “Antiviral nipple“ Doctor Light ”;

[No. 50420] - “LED device for irradiation of the oropharynx” [No. 28035] - “LED irradiating device”. These devices contain a power source, a program control unit and a light emission unit in the form of an LED.

However, the above devices are not intended to provide simultaneous monitoring of the patient’s condition with the treatment process, in particular, they do not contain temperature indicators.

Also known physiotherapeutic device described in patent RU No. 2456033. The device contains a power source, LEDs. The timer included in the power supply provides a time setting for the procedure of exposure to the oral cavity with light and automatically turns off the LEDs at the end of the procedure. The monochromatic radiation of LEDs affects the surface of the gums and teeth and helps to stop irritation of the surface of the oral mucosa, the treatment of chronic inflammation and inflammatory processes.

However, in the specified device there is no possibility of automatic adjustment of the mode of operation directly during treatment.

The closest analogue of the claimed utility model is "Diagnostic and preventive LED device" - patent RU No. 55292. The device includes a cylinder and a housing element, with a power source located in it, a temperature sensor with a display and a microprocessor and equipment for light exposure, represented by an LED. The device is turned on by a magnetic key made in the form of a reed switch. The display shows the patient’s body temperature.

However, in the specified device, the LED is turned on only when the temperature rises, so the device does not allow treatment, in particular, in the early stages of the disease, when the increase in body temperature may not be so pronounced.

The objective of the claimed utility model is to increase the efficiency of the treatment of diseases of the oral cavity, larynx and nasopharynx due to the correctly selected regimen and duration of therapy.

The essence of the claimed utility model lies in the fact that a therapeutic device for treating diseases of the oral cavity, larynx and nasopharynx, containing a working element made in the form of a hollow shell made of an elastic transparent material, is mounted on a support element of a non-magnetic material, which serves as a housing for the magnetically sensitive switches, a power supply connected to a data receiving unit, an analysis and data processing unit, a therapy process program control unit, a detection unit Accelerating temperature with a thermal sensor; installed at the base of the working element, the LED has a second LED identical to the first, installed in the base of the working element symmetrically to the first; a mirror screen implanted inside the shell of the working element in the form of a screen with the possibility of excluding the illumination of each of the LEDs by radiation from the neighboring one; an analog switch, an LED signal amplifier and an analog-to-digital converter entered into the data processing unit;

In addition, it is claimed that the implementation in the therapeutic device of each of the magnetically sensitive switches in the form of a sensor based on a magnetoresistive film.

The implementation of a therapeutic device based on a hybrid integrated circuit is also claimed.

The technical result of the claimed device is to increase the effectiveness of a therapeutic device for treating diseases of the oral cavity, larynx and nasopharynx, which is achieved by introducing into the device a second LED that works alternately with the first, so that each one performs alternately the functions of the emitter and receiver of backscattering tissue. The characteristics of backscatter radiation are highly dependent on the state of the irradiated tissues and carry information about the occurrence of a disease state. The radiation is received by one of the LEDs, converted into an electrical signal. In order for the receiving LED to respond only to the backscattering signal, a mirror grid is introduced between the LEDs in the form of a screen, which prevents one LED from illuminating the other. Alternating operation of the LEDs is provided by an analog switch. Next, the electrical signal is amplified by an amplifier, digitized by an analog-to-digital converter and compared with the reference values stored in the device’s memory. Based on the comparison results, the light exposure mode is selected. This allows you to adjust the impact directly during treatment without the need for manual control. The display of temperature information and the results of the analysis of the backscatter signal on the indicator of the disease state allows detecting the development of the disease at an early stage, when the temperature increase may not be expressed. The combined use of analysis of backscatter radiation and the identification of elevated temperature allows you to take adequate measures to adjust the treatment process, which, ultimately, increases the effectiveness of the entire treatment process.

The inventive therapeutic device includes a power supply 1, optical and electronic parts. The electronic part of the circuit is made on the basis of a hybrid integrated circuit in the form of a multilayer board, including a unit for detecting elevated temperature, block 3 of the reference pulse generator with current stabilizers, which performs the functions of a data receiving unit. The named block 3 of the reference pulse generator with current stabilizers is connected to the optical part of the inventive device. The optical part includes two light emitting diodes 4, 5 located at the base of the working element 6 of a rounded shape made of transparent elastic material and a mirror grid 7 of an extended shape placed inside the working element 6 from the side of its base. The LEDs 4, 5 are located symmetrically on both sides of the mirror grid 7 with the possibility of directing radiation into the working element 6. The mirror grid 7 eliminates direct radiation from one LED to another. The step size of the mirror grid 7 is selected smaller than the half wavelength of the LEDs used. To turn on the device, there are magnetoresistive sensors 8, one of which is connected to the power supply unit 11, and the second to the block 3 of the reference pulse generator with current stabilizers. To control the operation of the device and process information, a block 9 of diagnostics and automatic regulation of the treatment regimen has been introduced into the circuit, which displays information about body temperature and the presence of inflammatory processes on indicator 10 of the disease state. Block 2 for detecting elevated temperatures is connected with an integral temperature sensor 12. Block 3 of the reference pulse generator with current stabilizers includes a reference generator 13, which sets the control pulses for all electronic components of the circuit, an inverter 14, which provides alternate phase-to-phase switching of LEDs 4, 5 through stabilizers 15, 16 current. Block 9 diagnostics and automatic regulation of the therapy mode, which performs the functions of analysis and data processing and process control units, contains an analog switch 17, an amplifier 18 of the LED signals, an analog-to-digital converter 19, a decoder 20, a timer 21.

The work of a therapeutic device for the treatment of diseases of the oral cavity, larynx and nasopharynx is as follows.

The device is turned on with a magnetic key, which is brought closer to the magnetoresistive sensor 8 located in the device. Thereby, the power is connected to all elements of the claimed device from the power supply 1 through the power supply unit 11. Unit 2 for detecting elevated temperature starts to work. At normal temperature, a signal to start block 3 of the reference pulse generator with current stabilizers for LEDs is not supplied. In the diagram (see FIG. 1), the letter “Zh” shows the input for starting block 3. The signals from block 3 of the reference pulse generator with current stabilizers are then fed to the inputs “A” and “B” of the diagnostics and automatic control unit 9 of the therapy mode. It is recommended to start the device through a parallel electrical circuit shown in the diagram with the letter “E” also through a magnetoresistive sensor 8. A parallel circuit is connected to detect inflammatory processes in the oral cavity that are not accompanied by an increase in temperature. After starting, the LEDs 4, 5, integrated in the working element 6, made of a transparent elastic polymer material, for example, rubber and other materials, are alternately turned on. In more detail, the operation of the device is explained using the circuit shown in Fig.2. To alternately turn on the LEDs by analog switch 17, there is an inverter 14, from which the signal goes to the current stabilizer 15 of LED 5, and the antiphase signal goes to the current stabilizer 16 of LED 4. In parallel, this signal is fed to input “C ₁ ”, and antiphase to input “ With ₂ ”analog switch 17. This corresponds to the state in which LED 4 emits and LED 5 receives radiation. The radiation of the first LED, propagating inside the working element 6, comes out and affects the tissues of the mucous membrane of the oral cavity. Diffuse tissue scattered radiation again enters the work element 6 and is received by the second LED. The characteristics of diffuse scattered radiation depend on the state of the irradiated tissues. The radiation received by the second LED 5 is converted into the corresponding electrical signals, which are fed to the input “S ₁ ” of the analog switch 17 and connected to the output “D”. From the input "D" the signal through a linear amplifier 18 of the LED signals is fed to the input of an analog-to-digital converter 19, where it is converted to digital form according to the level of input analog signals. The digitized signals from the output of the ADC 19 are fed to the input of the decoder 20, where reference values corresponding to a number of states of the oral mucosa (from normal to pronounced pathology) are stored in the registers. If the values of the input signal correspond to the norm, then the output signal "S ₃ " of the decoder 20 receives the load signal to the input "load" of the timer 21, the latter being set for the minimum treatment time, and the signal from the output "S ₂ " goes to the indicator 10 of the disease state (pathological condition of the mucous membrane of the mouth and oral cavity), on which the green segment lights up. If a pathology is detected, then the output “S ₁ ” of the decoder 20 sends a signal to the indicator 10 of the disease state, on which the red segment lights up, while the decoder 20 loads the signal to the input “load” of the timer 21, and the latter sets the duration of treatment corresponding to the degree of development pathological condition. After the timer 21 counts the predetermined time, a signal to block the reference generator 13, which sets the clock pulses ensuring the operation of all elements of the circuit, is issued from the carry out output. After which the session ends.

The temperature in the oral cavity is determined by an integrated temperature sensor 12, operating with an accuracy of 0.1 ° C in a standard temperature range for medical thermometers. The integrated temperature sensor 12 contains memory elements and a preamplifier. From the output of the integrated temperature sensor 12, a signal linearly dependent on temperature is fed to the input of the temperature increase detection unit 2. At elevated temperature, it gives a trigger signal to the input "G" of block 3 of the reference pulse generator with stabilizers of the operating currents of the LEDs. In order to prevent the device from turning on spontaneously, for example, at an air temperature higher than the temperature of the human body, a second magnetoresistive sensor is provided, which turns off the optical part.

Example. The inventive device, manufactured according to the schemes presented in the application (Fig.1, 2), undergoes laboratory tests and performance checks in strict accordance with the test program. Optimal treatment regimens are being tested on experimental animals.
