Description

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

Phototherapeutic devices are widely used in medicine for the treatment and prevention of cardiovascular diseases, diseases of the joints, peripheral nerves, skin diseases, atherosclerotic lesions of the blood vessels of the heart, lower extremities, coronary heart disease, burns and surgical wounds. For this purpose, laser, lamp and LED light sources are used (V. Karandashov et al., Phototherapy. A manual for doctors. M., 2001).

According to the first law of photochemistry - “Photochemical transformation can occur under the action of only that light that is absorbed by a substance”, i.e. therapeutic effects are determined by the wavelength of optical radiation. Therefore, there was a need to create phototherapeutic devices that allow the use of several ranges of optical radiation for therapeutic purposes.

The prior art known "device for therapeutic and prophylactic radiation" (patent No. 2290225, priority from 04/27/2006). A device for therapeutic and prophylactic irradiation comprises a housing, with space for placing a patient in its center. On the inner walls of the body of this device, light sources are fixed, made in the form of sections of fluorescent lamps located parallel to the longitudinal axis of the patient’s body and connected to ballasts. Each section contains blue, green, yellow and red fluorescent lamps. Sections are divided among themselves by reflective panels which are rigidly fixed on the case. Before each section are placed with the possibility of movement relative to them screens. The screens are made in the form of curtains, which are placed in front of each section with colored light sources. Each curtain has 4 fixed positions, corresponding to

open areas of light emitting panels. The position of the blinds relative to the light sources is set using a mechanical or electric transmission mechanism. This device is the closest analogue of the claimed device.

Despite the advantages of the above device over previously used devices, it also has serious disadvantages. The disadvantages of the analogue are due, first of all, to its inconsistency with the level of modern technical development.

The main ones are:

1. The use of fluorescent mercury lamps inside the device is not justified:

a) they are not protected by anything and are in close proximity to the patient,

b) they heat up quickly enough, which requires the use of a special cooling system.

2. The rapid heating of the space inside the device’s case not only makes it uncomfortable to stay in it, but also does not allow for the long phototherapy sessions that are necessary for patients with a number of diseases, for example, such as various forms of jaundice and hepatitis.

3. Fluorescent lamps are sufficiently inert and require time to “warm up” in order to start working in color radiation mode. Therefore, it is impossible to simply switch the range of optical radiation, and to cut off unwanted (three!) Ranges is possible only by mechanical closing of the blinds.

4. Closing and opening of the curtains is carried out using a special mechanical or electric transmission mechanism, which complicates the device and increases its cost.

5. Hygienic treatment of the device, which should be carried out after each phototherapy session (especially in the treatment of patients with herpes, pustules and a number of other skin diseases), is inconvenient and may be insufficient due to the presence of many open elements inside the case: fluorescent lamps, curtain screens, parts gear mechanism.

6. The presence of open fluorescent lamps inside the housing may be a potential hazard to the patient. This is especially true of the electrical safety of the device, the danger of thermal damage due to accidental careless contact with overheated lamps, as well as possible mercury vapor damage if the glass tube of the lamp is damaged.

7. The complexity of the design of the device requires the necessary technical control, and phototherapy procedures should be carried out by medical personnel.

The proposed utility model for irradiating a body with monochromatic light “LED cabin” is devoid of the disadvantages of an analogue.

The technical solution consists in using a standard shower cubicle as the body, the walls of which are permeable to optical radiation, and as light sources - matrices of light-emitting diodes mounted in panels that are mounted on the outside of the translucent cabin walls.

LEDs are a product of nanotechnology. Their characteristics are monochromaticity, resistance to mechanical stress, duration of work (up to 50,000 hours), low power consumption, low cost. In addition, the wide market selection of LEDs of various ranges of optical radiation makes them at the present stage

development of technological progress, optimal light sources for phototherapeutic equipment.

The enhancement of the effect of light exposure in the proposed device is achieved by the simple action of an aqueous medium created using a standard shower. It is known that the reflection of light by skin moistened with water is 2 times lower than if exposure was in air (Applied laser medicine. A training and reference manual. Edited by H.P. Berlien, G.Y. Mueller. M., 1977).

In addition, the use of jets of warm water itself plays a positive healing role. For example, from the works of the famous Russian doctor A.S. Zalmanov “The Secret Wisdom of the Human Body (Depth Medicine)”, Minsk, 1993, it is known that by changing the pressure of the water jet due to the massage effect, an increase in capillary blood flow can be achieved. As A.S. Zalmanov points out: "... in an active state, some of the capillaries are able to receive seven hundred times more blood than at rest."

From a technical point of view, the use of a water shower solves the problem of overheating of body tissues under light exposure.

Figure 1 presents a diagram of the device "LED cab".

The device consists of a housing (1) made in the form of a standard shower cabin, the walls of which are made of transparent translucent material, for example, plexiglass. The cab is mounted on a pedestal (2) with a water drain system.

On three walls: the rear and two side (the front wall, which is the front door, is not shown in the drawing), panels (3) with matrices of light-emitting diodes of different ranges of visible light are fixed on the outside. Light emitting diodes are linearly arranged in a specific sequence. The light-emitting matrices are commutatively connected to a program control unit (4) located externally on one of the side walls of the cab.

The light-emitting matrices and the program control unit are supplied with power from an alternating current network through an adapter, or from an autonomous current source, for example, a battery.

The program embedded in the program control unit allows you to implement various options for light exposure, for example, turn on and off one of the light ranges with a continuous or pulsed radiation flux, alternate different colors of the light fluxes, adjust the light flux intensity, etc.

A shower head (5) is fixed under the upper wall of the cabin to irrigate the body with water jets, the intensity of the jets and their temperature are controlled by the valves of the shower mixer (6).

The simplicity of the design of the device, its electrical safety and the possibility of programming the phototherapy procedure, allow it to be used both in medical institutions for the treatment of various diseases, and at home for therapeutic or prophylactic purposes.

The device operates as follows.

The treatment regimen is set on the scoreboard: the range of optical radiation (red, blue, green, etc.), the dose of photo exposure (intensity and time), the nature of the light flux (pulsed, continuous), etc. The program includes a delay time for the inclusion of light radiation, this time is also set on the display of the program control unit. Press the button that includes the photo exposure program, and the countdown numbers are displayed on the board.

A person enters the cabin, turns on the shower, creating for himself a comfortable water-thermal regime. At this time, the phototherapy procedure begins in the specified color mode. After the time of the phototherapy procedure, the light panels turn off. In this case, a person can continue to take a water treatment. Then turn off the water shower and procedure

completed. The advantage of photo exposure at the same time as a water shower makes it possible to almost double the effect of light absorption by body tissues and thereby reduce the time of photoprocedure.

The utility model "LED cab" has the following advantages over analogues:

1. The simplicity of the design, which is determined by the use of standard parts (cabin, shower, stacked light panels).

2. The ability to use the device, both in medical institutions and at home.

3. The presence of an automatic photo exposure program greatly simplifies the use of the device.

4. The possibility of combined use of the light flux and the moving water environment increases the therapeutic effect.

5. Electrical safety and exclusion of the possibility of thermal damage to the skin.

6. Equally important is the comfort of the photo exposure procedure.

7. Durability and efficiency due to the low energy consumption of LEDs and their lifespan up to 50,000 hours.

8. Possibility of power supply, both from an alternating current main, and from an autonomous power supply.
