Description

The technical field to which the invention relates

This invention relates to a method for phototherapeutic irradiation of a pathological zone in an organism of a living being and to a lighting device for irradiating a pathological zone in an organism of a living being.

State of the art

Various methods of phototherapeutic irradiation of organisms and devices for their implementation are currently known.

UK application No. 2212010 (publ. 12.07.1989) describes a light therapy device using an LED matrix.

The utility model of the Russian Federation No. 87085 (publ. 09/27/2009) describes a physiotherapeutic apparatus for light and color therapy, containing LEDs with different radiation spectra, alternately affecting the pathological zone of a living organism.

RF patent No. 2145247 (publ. 02/10/2000) discloses a photomatrix therapeutic device in which optical radiation sources are placed in a substrate that repeats the shape of the pathological zone, and the device parameters are calculated from a system of expressions linking the characteristics of the source with the parameters of the pathological zone.

In US patent No. 10022555 (publ. 07/17/2018) describes a phototherapy device in the form of a band with fixed LEDs.

In the Chinese utility model No. 204134057 (publ. 02/04/2015), a wearable LED physiotherapy instrument is proposed, in which a matrix of LEDs is fixed on an elastic carrier worn on the patient's body. A similar solution is described in the application of Taiwan No. 201605507 (published on 16.02.2016).

However, all of these and many other devices provide an integral nature of the effect, since the irradiation is carried out on the entire affected area from a certain distance for a given period of time. Meanwhile, the activation of living (undamaged) tissue around the pathological zone can enhance the activity of this tissue in the transfer of oxygen, nutrients, medicines to the border of the pathological zone. In this case, it is advisable to irradiate tissues in the direction from the intact zone to the pathological zone and back to activate the transfer phenomena. Such activation will be especially intense if the radiation acts not only on the superficial (subcutaneous) capillaries, but also on those located in deeper tissues.

Detailed Description of Embodiments

To implement the method of phototherapeutic irradiation of a pathological zone in the body of a living being according to the first aspect of the present invention, an illumination device according to the second aspect of the present invention can be used. One possible embodiment of such a lighting device is shown in FIG. 1 and 2.

The illumination device for irradiating a pathological zone in the body of a living being according to the second aspect of the present invention comprises two opposing bases 1 and 2 (Fig. 2), made elastic. Such a design of the bases of the lighting device allows it to be used on almost any surface of the body of a living creature, be it a person or an animal, since the elastic material of the bases 1 and 2 makes it possible to apply the lighting device according to the second aspect of the present invention, following the curves of the surface covered by this device. As a material for the lower (in Fig. 1) base 1, intended to be applied to the surface to be irradiated, a rubber or polyurethane film with a thickness sufficient to accommodate the elements of the lighting device described below can be used. The upper (in Fig. 1) base 2 can be made, for example, of polyamide fabric. Those skilled in the art will understand from the following description that the material for a particular of the bases 1 or 2 may be different to ensure the manufacture and operation of the lighting device according to the second aspect of the present invention.

The bases 1 and 2 are interconnected along the perimeter by radiators 3, each of which has at least one radiator 4. As such radiators 4, LED matrices or single LEDs can be used. Each emitter 4 is designed to create radiation with a spectrum that provides the required phototherapeutic effect when irradiating the pathological zone in the body of a living being. In particular, it can be radiation at a wavelength of 830 nm, which can penetrate through human skin to a depth of 60 mm (see S. G. Abramovich. Phototherapy. - Irkutsk: RIO FGBU "NTsRVKh" SB RAMS, 2014, p. 17, Fig. 2). Of course, the specific wavelength of the radiation generated by the emitters 4 may be different, which is determined both by the nature of the pathological zone and the required type of exposure.

All emitters 4, as seen in FIG. 1, face the inner space between the bases 1 and 2. In this case, the inner surfaces of the bases 1 and 2 are made to reflect radiation from the emitters 4. This can be achieved both by using a mirror coating applied to the inner surfaces of the bases 1 and 2, and by placing on them mosaic elements 5 in the form of a close-packed matrix reflecting radiation from emitters 4. The shape of such elements 5 can be, for example, hexagonal, as shown in FIG. 2, either square or octagonal with square inserts, or any other that provides continuous filling of the surface of the base 1 or 2. Mosaic elements 5 can be made of both a solid material (for example, aluminum), and flexible (for example, rubber or polyurethane). In the first case, the reflective properties can be provided by polishing the surface of the mosaic elements 5, and in the second case, by applying a reflective coating to their surface.

The mosaic elements 5 made of hard material, attached to the base material 1, for example with glue, can be small enough to allow the base 1 to bend when applied to the irradiated surface and to abut against it.

The aforementioned heatsinks 3 can be installed substantially adjacent to one another, although spaced apart, as shown in FIG. 2. The fixing of radiators 3 to both bases 1 and 2 can be done in any suitable way, for example, with glue or screws. The surfaces of the radiators 3 around the radiators 4 can have a coating that reflects radiation from the radiators 4.

To maintain the gap between the bases 1 and 2, spacers 6 are installed at predetermined locations that do not absorb (transmit) radiation from the emitters 4. These spacers 6 can be made, for example, in the form of glass or plastic bodies with the surface of an ellipsoid of revolution. In particular, it can be glass or plastic balls, although other forms of spacers 6 are quite possible, which can, for example, be glued to the corresponding mosaic elements 5 on both bases 1 and 2, or fixed in another way. For example, the spacers 6 can be in the form of cylinders, the height of which is equal to the required distance between the bases 1 and 2. In the middle of such cylinders, a through hole can be made through which a thread is passed through all the spacers 6 and through the holes in the bases 1 and 2 and fixing dividers 6.

Thus, a kind of flexible light guide is formed between bases 1 and 2.

In one of the bases (in Fig. 1 this is the lower base 1) there are domed Fresnel lenses 7 intended for focusing and removing radiation from the inner space of the formed flexible light guide to the irradiated surface. Dome lenses 7 Fresnel, produced by the industry, can be glued into the holes in those mosaic elements 5, which do not have spacers 6.

The lower (in Fig. 1) surface of the base 1, applied to the body, can have a coating 8 in the form of a sterile optically transparent film, which can be used, for example, a transparent ultrathin easily stretchable polyurethane breathable antimicrobial incisal film, which is tightly fixed on the irradiated surface and repeats the relief of body parts (see, for example, the site http://medams.ru/intsiznaya-plenka).

FIG. 2, the radiators 3 are shown installed around the perimeter of the base 1, but this is only a possible (preferred) embodiment. In principle, it is sufficient to have only one row of emitters 4, placed on a flexible base and facing the irradiated surface. The specific implementation of such a device can be any, providing the implementation of the method according to the first object of the present invention. For example, it can be a row of emitters fixed on a flexible plate with spacers minimum in height. Such a plate is fixed over the irradiated pathological zone by any suitable means so that the emitters are directed to the irradiated skin, and the dividers between them prevent skin burns.

The method according to the first aspect of the present invention can be carried out with the lighting device according to the second aspect of the present invention as follows.

A lighting device with emitters 4 (or just one row of emitters 4), which create radiation with a spectrum providing the required phototherapeutic effect, is placed in direct contact with the skin over the irradiated pathological zone of a living being so that some of the emitters 4 are located within the projection of this pathological zones on the skin, and the other part is outside this projection. A number of emitters 4 or a lighting device with these emitters 4 is fixed on the body of a living creature by any suitable means, for example, using an elastic bandage or using belts specially attached to the described lighting device in order to exclude the possibility of involuntary or deliberate displacement of the emitters 4. Irradiation of pathological the zones are performed by turning on the emitters 4 in turn to implement this irradiation in the traveling wave mode.

Preferably, instead of one row of emitters 4 above the pathological zone, it is possible to place two opposite rows of such emitters and turn them on in pairs in both rows. It is even more preferable to place two additional opposing rows of emitters 4 above the pathological zone, located in a direction intersecting the direction of the other two rows. The best result will be when every two opposing rows of radiators are perpendicular to one another. In this case, the emitters 4 are switched on alternately in pairs in each direction independently. That is, for example, a traveling radiation wave in one direction can begin when a traveling radiation wave in the other direction has reached the middle of the irradiated zone; or both traveling waves can start at the same moment, but the traveling radiation wave in one direction has time to pass twice, while the traveling radiation wave in the other direction passes once. Specialists can choose any other combinations and modes.

It should be noted that the switching on of the emitters 4 can be carried out alternately in the direction from the outside to the pathological zone and from it outside. The propagation speed of the traveling radiation wave can be selected in a wide range. In particular, this speed can be comparable to the speed of movement of blood through the blood vessels. The sequence of turning on the emitters 4 is set by the corresponding program that controls the operation of the controller, which issues on-off signals to the emitters 4, or this program is implemented in hardware, as is known to specialists.

FIG. 3 shows a schematic view of the distribution of the luminous flux density generated by the lighting device of FIG. 1, when the emitters 4 are placed in two rows one opposite the other. Direction "a" corresponds to the direction of the row of emitters 4, and direction "b" corresponds to the direction perpendicular to it (ie, the side of the flexible light guide without emitters 4 in Fig. 2). Shades of gray correspond to the change in the intensity of the light flux from its absence (black) to the maximum intensity (white). As seen in FIG. 3, due to the use of reflecting elements 5, in the direction "b" two radiation maxima are formed, the projections of which are shown in the horizontal plane under the corresponding spatial maxima. This distribution of irradiation intensities, shown for a specific point in time, moves in the "a" direction due to the corresponding switching or modulation of the emitters 4 simultaneously in both rows. Under a different irradiation regime, the intensity distribution may be different.

Thus, with the help of the present invention, an irradiation mode is formed that activates living (undamaged) tissue around the pathological zone, which can enhance the activity of this tissue in the transfer of oxygen, nutrients, drugs to the border of the pathological zone. In this case, it is possible to irradiate tissues in the direction from the intact area to the pathological area and back to activate the transfer phenomena. If the selected radiation from the emitters 4 will act at a greater depth, passing through the skin and adjacent body tissues, this activation may be more effective than surface irradiation, which will have a more effective phototherapeutic effect.

The present invention has been described using examples of its implementation, which are purely illustrative and do not limit the scope of protection of the present invention, defined only by the attached claims with regard to possible equivalents.
