Description

The utility model relates to medicine and medical equipment and is intended to influence the human body in order to mobilize its protective forces through phototherapy in the spectral range from infrared to ultraviolet and cryotherapy.

A device is known for thermo- and cryo-exposure to acupuncture points, in which a thermoelectric cooler (SU 797686) is used as a source of thermo- and cryo-exposure.

Due to the design (the small area of the acting element intended for contact with the acupuncture point), the device does not allow thermo- and cryotherapy of extended areas of biological tissues.

A device is known in the form of a fixing bandage, in which a set of thermoelectric coolers connected via a battery to a power source, as well as a temperature sensor (SU 1674834) are mounted on the acting element.

As a result of local thermal or cryogenic exposure to biological tissue, the expansion or contraction of the blood microvasculature in the affected area occurs, respectively. Alternating cyclical changes in the operating mode of the acting element from heating to cooling increases the efficiency of thermo- and cryotherapy and thermocryomassage. The thermoelectric dressing provides for work only in a fixed position, which does not allow thermocryomassage of extended areas of biological tissues.

A device for light reflection therapy, which has optical emitters for each of the spectral ranges of blue (470 nm), or green (567 nm), or yellow (590 nm), or red (660 nm), or infrared (890 nm or 939 nm) . The device operates by generating pulses of the indicated wavelengths with switching modulation modes (RU 2074697).

The disadvantage of this device is that during its operation, the use of radiation with different wavelengths is possible only in sequential mode using a quick coupler, which does not allow the use of radiation with different wavelengths simultaneously. The use of only one light exposure does not allow a comprehensive approach to the treatment of the disease.

A physiotherapeutic apparatus is known in which laser diodes are used to obtain a therapeutic effect in the visible and infrared wavelengths. Laser diodes with emission spectra that form a pair of spectral neighbors on a scale of wavelengths are included in the electrical circuit of the device, such as red and infrared, yellow and orange, blue and green. The layout of the electrical circuit allows you to use selective control radiation of one of the pairs of these spectra (RU 2090224).

The disadvantage of this method of exposure and apparatus is that in its implementation can be used only a pair of adjacent on a scale of wavelengths. This reduces the capabilities of the apparatus in the treatment of various diseases, its effectiveness and limits the possibility of complex effects on the patient's body in its various conditions. This device has a limited scope due to the use of only one type of exposure.

The technical result achieved by the utility model is to increase the effectiveness of therapeutic effects on

biological tissue by increasing the degree of expansion and contraction of microvessels, anti-pain, anti-inflammatory, immunostimulating and other biological effects for the correction of pathological and stressful conditions of the body at various degrees of its functional activity by combining exposure to biological tissue with elevated and lowered temperatures using a thermoelectric cooler and phototherapeutic radiation of various lengths waves.

The essence of the utility model is to achieve a technical result for a device for photocryotherapeutic exposure, which contains an exposure unit, thermoelectric coolers and a unit of emitters from the dynamics of radiation waves from infrared to ultraviolet, connected to their power sources, photosensitive sensors and thermosensitive elements associated with their programmable switches operation, the control unit and associated indicator of the operation parameters of the device and the control panel for installation parameters of thermoelectric coolers and emitters, the control unit being connected to thermoelectric coolers and emitters through programmable switches for their operation and to the control inputs of their power supplies, with programmable switches for thermosensitive elements and photosensitive sensors, and the control unit is configured to simultaneously enable the kit of at least four emitters with different radiation wavelengths, sequential change of sets emitters, regulating the duration of exposure of each of the sets, continuous or pulsed operation of each of the emitters, regulating the radiation power of each of the emitters, the duration of heating and cooling on each thermoelectric cooler, radiation sources, photosensitive sensors, or

elements that ensure transmission of radiation from emitters to photosensitive elements, as well as thermoelectric coolers and thermosensitive elements, for each wavelength, the emitter block contains at least two series-connected emitters, and on the acting element emitters or elements transmitting radiation from emitters, arranged regularly.

As emitters use lasers, laser diodes, LEDs, lamps with a narrow-band emission spectrum.

In one embodiment of the device, thermoelectric coolers are configured to provide a temperature effect of −50 to + 70 ° C. on their surface.

The block of emitters can be configured to not overlap the irradiation spots from the emitters in the irradiation zone.

The block of emitters can be configured to overlap the irradiation spots from the emitters in the irradiation zone.

The utility model is illustrated by drawings, where in Fig. 1 a block diagram of a device is shown, in Fig. 2 is an acting element, in Fig. 3 is a diagram of switching on radiation sources.

A device for photocryotherapeutic exposure contains an exposure unit 1, thermoelectric coolers 2, 3, 4 and a block J of emitters 5, 6, 7 with the dynamics of the radiation waves from infrared to ultraviolet, connected to their power sources, respectively 8 and 9. The device also contains photosensitive sensors 10, 11, 12 and heat-sensitive elements 13, 14, 15 associated with the programmable switches of their work, respectively 16 and 17. To implement a given program, the device contains a control unit 18 and associated indicator 1 9 operation parameters of the device and a control panel 20 for setting thermoelectric parameters

coolers and radiators. The control unit 18 is connected: with thermoelectric coolers 2, 3 and 4 through a programmable switch 21 of their work and with the control input of the power source 8 thermoelectric coolers; with emitters 5, 6, and 7 through a programmable switch 22 of their work and with the control input of the power source 9 emitters; with a programmable switch 17 temperature-sensitive elements 13, 14, and 15; with a programmable switch 16 photosensitive sensors 10, 11 and 12. The control unit 18 is configured to provide simultaneous inclusion in the work of a set of at least four emitters with different wavelengths of radiation, sequential change of sets of emitters, control the duration of exposure of each of the sets, continuous or pulsed operation of each of the emitters, regulation of the radiation power of each of the emitters, the duration of heating and cooling at each thermoelectric ohm aditele. The exposure unit 1 contains: emitters 5, 6, 7, photosensitive sensors 10, 11, 12 or elements that transmit radiation from emitters to photosensitive elements (not shown in the drawing), as well as thermoelectric coolers 2, 3, 4 and thermosensitive elements 13, 14, 15. For each wavelength, the emitter unit J contains at least two series-connected emitters, and emitters or elements transmitting radiation from the emitters are arranged regularly on the acting element.

As emitters use lasers, laser diodes, LEDs, lamps with a narrow-band emission spectrum.

Thermoelectric coolers 2, 3, 4 are made with the possibility of providing on their surface temperature effects from -50 to + 70 ° C.

The block of emitters can be configured to not overlap the irradiation spots from the emitters in the irradiation zone or to overlap the irradiation spots from the emitters in the irradiation zone. In the first case, optical elements are installed at the output ends of the optical fibers or directly on the emitters.

Thermoelectric coolers and emitters have an arbitrary shape and are located on the exposure unit in the order determined by the therapeutic task, while the radiation sources are located regularly.

Thermoelectric coolers in the exposure unit are controlled using the control unit, while for each thermoelectric cooler the heating-cooling modes are set individually for each thermo-cryocycle.

On the surface of the thermoelectric cooler facing the biological tissue, interchangeable nozzles (not shown in the drawing) made of a material with high thermal conductivity (copper, aluminum, etc.) can be installed, which allows them to be disinfected after removal from the exposure unit. Thermosensitive elements are also installed there (temperature sensors - thermistors or other semiconductor devices).

Temperature sensors are designed to control the temperature from the side of the thermoelectric cooler facing the biological tissue (as well as the temperature of the replaceable nozzles, if installed) when choosing the temperature necessary for exposure.

To effectively remove heat from the opposite biological tissue of the thermoelectric cooler side, a radiator and / or fan (not shown) can be used in the device. To obtain the lowest (high) exposure temperature with

Using thermoelectric coolers, a cascade connection of thermoelectric coolers can be implemented in the device.

When using a thermoelectric cooler, structurally made with a hole in the center, the emitter or means for supplying radiation to the exposure unit (light guide) is installed inside this hole.

To maintain a permanently installed radiation power in the emitters during the exposure, stabilization of the radiation power and stabilization of the temperature of the emitters were used.

When emitters and photosensitive sensors (photodiodes) are placed outside the exposure unit, the radiation is supplied to the biological tissue using an optical fiber, the output end of which is fixed to the exposure unit. In this case, the radiation power of the emitter is controlled using an optical fiber, one end of which is fixed to the exposure unit, and the other end is attached to a photosensitive sensor (photodiode). The radiation reflected from the biological tissue enters the optical fiber and then enters the photosensitive area of the remote photosensor (photodiode).

As a result of local thermal or cryogenic action on the biological tissue, the expansion or narrowing of the blood microvasculature in the affected area occurs, respectively. Alternating cyclical changes in the operating mode of the acting element from heating to cooling increases the efficiency of thermo- and cryotherapy and thermocryomassage.

Under the influence of low-intensity laser and incoherent light emitting diodes within the spectral range of 0.5 ... 1.6 μm, the dilation of arterioles occurs, and the veins of the blood microvasculature already for 1 - 10 minutes depending on the power of photo exposure to the biological tissue (Kozlov V.I. , Builin V.A., et al. "Fundamentals of Laser Physio- and Reflexotherapy", Samara-Kiev, 1993, p. 60).

To use the device during physiotherapeutic exposure, select temperatures for thermo- and cryotherapy on biological tissue; duration of cooling and heating in one cycle; number of cycles; exposure time; radiation power of emitters; dose of photo exposure; frequency of modulation of radiation of emitters; synchronization mode of emitter radiation with thermal and cryogenic effects.

The synchronization modes of radiation with thermal and cryotherapy allow you to choose the constant inclusion of emitters during the entire time of photothermocryotherapy, the inclusion of emitters only during thermal exposure, the inclusion of emitters only during cryotherapy, the shutdown of emitters during thermal and cryotherapy on biological tissue.

After setting the required values of the parameters of photothermocryotherapy, the acting element 22 of the photothermocryotherapy device is placed on the biological tissue and, depending on the purpose of the therapy and the extent of the area of the biological tissue, photothermocryotherapy is carried out at a fixed position of the acting element 22 or by slow rotational-translational movements of the acting element 22. Depending on the indications of therapy, the procedure is carried out within 10 to 30 min. (if necessary, arrange breaks between thermal and cryotherapy ) To apply a set of different methods of photothermocryotherapy, the data for setting the parameters of photothermocryotherapy are sent to the microcontroller 3 from an external personal computer in accordance with the selected therapy methodology.

The external computer displays the set temperature values of each of the thermoelectric coolers in the acting element, the radiation power, the dose of photo exposure, the modulation frequency of the emitters, the number of thermo-cryocycles,

the set exposure time and their countdown during the procedure.

The device operates as follows.

A diagnostic examination of the patient is carried out, the ranges of the used wavelengths, the used temperatures (both plus and minus) are selected, the required exposure modes are set using the control unit (emitter power, exposure duration, change of sets of wavelengths, frequency, etc.).

When choosing exposure parameters are guided by the following:

Depending on the functional state of the organism, a set of radiation of four or more wavelengths is used in various combinations and sequences, with different exposure parameters (power, total duration, pulse or continuous nature of the effect). Use the irradiation time for each of the wavelengths from 0.1 ms to 30 minutes, a frequency of up to 10,000 Hz with an absorbed dose of 0.01-10 J / cm ² . The ultraviolet range (320 nm) is used to affect the melanin-forming structures of the skin in order to stimulate the immune system, affect metabolic processes in the skin, this range has an anti-inflammatory effect and is also used for tanning, it is used continuously. The blue wavelength range (470 nm) is used to affect the surface structures of the skin, in particular, the skin nerve endings and chromatophores, the mode of use is continuous or pulsed. The green range (560 nm) has a slightly greater penetrating effect deep into the skin structures, therefore, along with continuous exposure, a pulsed mode of operation is used. The yellow range (580 nm) is more efficient in pulsed mode

use and very well removes inflammation both on the surface of the skin and from deeper subcutaneous structures, affects the permeability of cell membranes and the peripheral nervous system by changing the permeability of cell membranes to calcium. The scope of this range is the treatment of degenerative inflammatory diseases of the nervous system, the treatment of radiation epithelitis, peptic ulcer, mastopathy and other diseases. The red range (630-680 nm) is used to treat dermatological diseases, improve microcirculation and to influence the blood. The infrared range (starting from 890 nm) has the highest penetrating ability and is designed to affect the deep structures of the body for the purpose of immunostimulation, it has a strong anti-inflammatory and anti-pain effect.

The use of continuous radiation and low-frequency radiation (up to 80-100 Hz) with a predominance of blue, green and yellow and infrared wavelengths has a calming effect and has a beneficial effect on the nervous system. The combination with the predominance of the ultraviolet, yellow, red and infrared wavelengths in the combination of continuous radiation and frequencies up to 1000-1500 Hz has a tonic effect. A stimulating effect for relieving stressful situations and preventing disease is used in combination with the predominance of the ultraviolet, blue, red and infrared wavelengths in the frequency range from 1500 to 10000 Hz.

The use of emissions of several wavelengths simultaneously (at least four) does not mean that they all work in the same mode. This means that in the implementation of a specific impact, radiation of at least four wavelengths in

range from infrared to ultraviolet, and the exposure parameters of each wavelength can be different.
