Description

The utility model relates to medical equipment, namely to phototherapeutic devices.

In medical practice, various light-emitting devices based on LEDs made in the form of plates or flexible elastic dressings began to be used for physiotherapeutic purposes. Flexible elastic dressings that emit monochromatic light of various ranges are convenient for applying to various parts of the body.

One of the first developments is the “Light Emitting Bandage” described in the Utility Model Certificate RU 2511, publ. August 16, 1996 Bull. No. 8.

It consists of a flexible elastic base made of medical silicone and a matrix of LEDs located in it.

This device has two drawbacks:

1. Mains power through the adapter;

2. The lack of a cooling system for heating LEDs. Therefore, during the phototherapy procedure, it is necessary to place a cloth moistened with water between the matrix and the body surface, which, of course, reduces the effect of exposure.

Other similar developments also have these drawbacks (A.M. Korobov, V.A. Korobov, T.A. Lesnaya "Phototherapeutic apparatuses of Korobov series" Barva ", Kharkov, 2008)

In US Pat. No. 6,350,275, the light emitting device is made in the form of a circular bandage worn on an arm or leg; the light-emitting dressing has a matrix of LEDs of blue and green range; autonomous battery. Technically, the patent is not implemented, possibly due to the lack of a cooling system in this device.

More perfect and technically implemented is the “Device for transcutaneous irradiation of blood with optical radiation - a light-emitting bracelet” (utility model patent RU 66963). It is taken by us as the closest analogue.

The device "Light-emitting bracelet" consists of a watch case made of plastic, in which the battery is located, a microcontroller with program control; the bracelet itself is made of two-layer medical silicone, on the inner surface of the bracelet there is a matrix of superbright light-emitting diodes (LEDs), the matrix is connected by electric wires to a power source, metal heat sinks-coolers are located between the LED lines for heat dissipation. The housing has a slot for recharging the battery.

The analogue - the device “Light-emitting bracelet” is an operating model that has passed technical and preliminary medical tests. The following disadvantages were identified:

1. during operation of the device there is a gradual, uncontrolled decrease in battery capacity, which leads to a decrease in the power of optical radiation and, accordingly, a decrease in the therapeutic effect or its complete absence;

2. An uncontrolled decrease in the voltage level and current strength can lead to the matrix being turned off during the procedure;

3. The device provides for the use of the entire spectrum of optical radiation through the use of various matrix options from short-wave (violet-blue part of the spectrum) to long-wave (infrared radiation). However, the efficiency of absorption of light by blood in the range of 400-480 nm is minimal due to the weak penetration of optical radiation of this range through the skin. In this regard, it is necessary to increase the time of photo exposure, which is not always effective.

The objective of the utility model is to create a more advanced device, devoid of the disadvantages of the analogue.

The technical solution is achieved through the use of a light polarizer in the form of a plate placed in front of the light-emitting matrix and a voltage stabilizer located in the device body.

Polarized light has a pronounced biological effect and penetrates deeper into the body tissue than ordinary optical radiation, thereby ensuring the achievement of a therapeutic effect.

To achieve this goal, the use of LED matrix with a variable (adjustable) spectrum of optical radiation is also promising.

This is allowed by new generation LEDs - RGB diodes with a variable emission spectrum, developed in the laboratory of Academician of the RAS Zh.I. Alferov and entered into serial production.

To monitor the level of battery charge and the mode of operation of the device, indicators based on LEDs are installed.

The proposed device is schematically represented in figure 1

The device "Autonomous light-emitting bracelet with a polarizer" consists of a housing 1 made of plastic and connected to an elastic bracelet 2 made of two-layer medical silicone. Inside the case there are: a battery 3, a microplate 4, with a software block 5 located on it and a voltage stabilizer 6, as well as indicators of the device's operating mode and battery charge level - 7.

Outside, on the upper wall of the housing 1, directly above the LEDs 7, there is an on / off button for the device 8 made of transparent material, for example, plexiglass, as well as a control panel 9 with a liquid crystal screen 10, on the side wall of the housing 1 there is a socket for a charger plug battery 11.

The bracelet 2 consists of two parts connected to the housing 1. On the inner side of one of the parts of the elastic bracelet 2 is a matrix 12 consisting of light-emitting diodes and metal heat sinks-coolers located between the LED lines; along both sides of the light-emitting matrix 12 there are sensors of physiological parameters of the organism 13 (pulse rate, blood oxygen saturation, etc.). The light-emitting matrix 12 and the physiological parameters sensor 13 are connected to a power source 3 and a control panel 9 of the electric wires 14.

The radiating surface of the LED matrix 12 is covered with a thin transparent plate - a light polarizer 15.

An embodiment is a matrix in which each LED is located in a separate recessed cell, coated on top with a polarizing plate.

Device - an autonomous light-emitting bracelet with a polarizer works as follows:

1. the bracelet is put on the arm;

2. by pressing button 8, the device is turned on; while the blue indicator lights up, indicating a full battery charge;

3. Using the control panel 9, one of the photo-action programs is installed on the screen;

4. by repeated pressing of a button turn on the LED matrix; at the end of the procedure, the device automatically turns off;

5. if necessary, turn off the device before the end of the programmed time, press button 8;

6. to determine physiological parameters, for example, heart rate during the procedure, press the corresponding button on the control panel 9; while on the screen there are numbers reflecting the parameters of the determined physiological indicator;

7. If, when the device is turned on, the device indicator and the LED chain on the bracelet flash 3-4 times, then this indicates the need to recharge the battery.

The battery is charged using a standard charger from the network ~ 220V. At the same time, the red indicator lights up while charging the battery; when the battery is fully charged, the red indicator turns off.

"Standalone light-emitting bracelet with a polarizer" has the following advantages over analog:

1. The proposed utility model is a compact multifunctional device;

2. the presence of a matrix with variable ranges of optical radiation involves the expansion of the range of therapeutic effects;
