Description

The utility model relates to medical equipment, namely to devices for phototherapy.

Currently, the treatment of purulent wounds and trophic ulcers, skin diseases, peptic ulcer of the stomach and duodenum is carried out mainly with medication. The use of laser technology and UV rays give certain results [1,2,3,4], but their use is expensive and has negative consequences, like all high-power emitters.

All devices were developed in the 70s and are outdated both morally and technically. All equipment is based on extracorporeal blood irradiation methods [4]; helium-neon lasers “ALOK” and “VLOK” and semiconductor lasers “Mulat” and “Mustang” are used, which have serious drawbacks.

First of all, you need “good” veins for blood sampling, which is traumatic in itself, additional blood preservatives (heparin) are needed to stabilize coagulation, special one-time cuvettes for irradiating blood, and finally, invasive methods are contraindicated in patients with hemophilia and thrombocytopenia diseases.

Existing methods of external exposure to skin surfaces:

- using a matrix system emitting infrared radiation;

- using matrices of superbright light λ = 440 nm, by scanning.

These methods are simple, but their effectiveness is not great. This is due to the fact that in the visible part of the solar spectrum, the depth of light penetration into biological tissues of 0.5-2.5 mm [5] reflects up to 50% of the incident light [6], pp. 58-70.

The closest analogues are the described devices for percutaneous irradiation of blood, based on red and infrared radiation. This is the Israeli Biobeam 940 apparatus with wavelengths λ = 640 nm and 940 nm used for the treatment of joint and vascular diseases, as well as the domestic Dune-T apparatus with wavelengths λ = 660 nm ± 15 nm and 840-950 nm used with an irradiation area of 10 cm ² [3], pp.128-131.

The technical result achieved by using the proposed utility model is the creation of a more advanced device for the treatment of purulent wounds, trophic ulcers, skin diseases, peptic ulcer of the stomach and duodenum using different wavelengths of the visible spectrum of sunlight (blue 430-480 nm, green 500 -530 nm, orange 590-630 nm, red 650-740 nm).

The achievement of the technical result is due to the 1st law of photochemistry, which states that photochemical conversion can occur under the influence of the light that is absorbed by the substance, therefore, in the light of one spectrum, LEDs with different wavelengths are chosen. It is also based on the conclusions of the founder of phototherapy, Nobel laureate Niels Finzen, who established that at the place of pressure on the biological tissue, the penetration depth of light increases tenfold.

It has been established that when using radiation with a wavelength of 441 nm for the treatment of trophic ulcers, an anti-inflammatory effect is observed, an increase in the activity of phagocytic cells and polyperation of connective tissue [3], p.271.

The impact of different wavelengths of one spectrum is enhanced by the integrated use of other types of spectrum that will provide treatment for several diseases at the same time. The use of monochromatic light sources with different wavelengths determines a high therapeutic effect in the treatment of these diseases.

The claimed result is achieved by the fact that the light-beam dressing for the treatment of purulent wounds, trophic ulcers, skin diseases, peptic ulcer and duodenal ulcer, made of dense tissue material, includes a strap and "Velcro" for tight fastening, a matrix of 60 LEDs made of silicone compound SIEL , a control unit with a timer, buttons for starting the LEDs and buttons for starting programs, a power compartment for the autonomous and mains power supply through the converter and the connecting cable, and the LEDs are mounted in the matrix odes of 4 spectral types with different wavelengths in each, protruding by 2–3 mm and located at a distance of up to 10 mm.

It is preferable to use superbright monochromatic LEDs manufactured by Sharp (Japan).

The use of different brightness wavelengths as sources of superbright LEDs will make it possible to obtain effects characteristic of these ranges [1,2,3].

National polyaddition silicone compounds SIEL are composite silicone materials polymerized by the polyaddition mechanism or under the influence of UV radiation, capable of vulcanization both in open and closed volumes, at any thickness of the layer, without release of by-products, at room or even sub-zero temperatures and up to temperatures of the order of 250-3000 ° C. The temperature range of the compounds is from minus 800 ° C to 300-3500 ° C. Areas of application are: electronics, electrical and radio engineering, aviation, fiber optics, medicine. SIEL materials are characterized by high optical and chemical purity, biological inertness and complete non-toxicity.

The proposed device consists of (Figure 1): A is a front view in an assembled state; B - front view of the control panel; B - side view of the control panel: light beam dressing 1 made of dense fabric material with a strap and Velcro for tight fastening on

places of human ulcers (dressing size 500 × 150 with a strap 200 × 50), a matrix of 60 LEDs 2 (size 280 × 100) hermetically mounted in a flexible plate 4 mm thick of silicone compound SIEL, protruding 2-3 mm above the surface of the plate (which provides the necessary and sufficient pressure on the tissue) at a distance of 10 mm from each other; control unit 3 (size 60 × 160 × 20) with a timer of mode 4, buttons for starting the LEDs 5, buttons for starting the program 6, power compartment 7 autonomous (8АКБ × 2500 mAh) and from the network via a converter with a voltage of 6 V; steel plate 8 for fastening to a belt (pocket); socket for power supply from the network 9; power cable 10.

The treatment programs include various emission spectra, exposure time, alternate or combined wavelengths.

When using a light-beam dressing, a set of transparent disposable films is provided for application to the place of use of the dressing in order to avoid subsequent sterilization of the product.

The device operates as follows:

A light-beam dressing is applied to the ulcer, the place of a skin disease, to the veins of the hands (feet) with a snug fit through a transparent film, depending on the type of the disease, a program is selected and installed on the control panel (time and radiation spectra) 4,5 and program 6 starts treatment or prevention of the disease. After the time expires, timer 4 turns off the LEDs. The patient removes the dressing himself or with the help of a nurse.

The use of a light beam dressing is assumed through a disposable transparent film, which avoids sterilization, although it is possible.

The proposed device has the following advantages:

The use of four types of spectrum and different wavelengths in one spectrum significantly increases the therapeutic capabilities of the product.

Due to the LEDs acting on 2-3 mm and their position from each other (up to 10 mm), a uniform light spot and an increase in light penetration by several times are realized.

The design of the device allows it to be easily used without causing discomfort to the patient. The provided autonomous and stationary power sources ensure the operation of the device both in the hospital and outside it;

The device is simple and inexpensive to manufacture.
