Description

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

In all countries of the world, more than half of older people suffer from coronary disease of the lower extremities.

“In the Scandinavian countries, chronic critical ischemia of the lower extremities affects up to 800 people per 1 million inhabitants. Of these, 200 patients undergo high amputations. In Britain and Ireland, 400 patients per 1 million inhabitants. Within one year of diagnosis, 25% of patients undergo high amputation of limbs. A fatal outcome after amputation is observed in 40-45% of cases, after 5 years already 70% of patients die, and after 10 years - almost everything ”(BC Saveliev, V. M. Koshkin. Critical lower limb ischemia. M., Medicine, 1997 )

A huge arsenal of modern medicines is used for treatment: vasodilators, anticoagulants, antiplatelet agents, statins to lower cholesterol, ganglion blockers, etc.

However, despite the full-fledged drug therapy, the disease progresses. According to the statistics of European joint documents, critical ischemia occurs in 300-1000 patients per 1 million people.

The main cause of the clinical manifestations of coronary disease is a decrease in organ blood flow. Ischemia of organs and tissues develops due to the action of factors such as change

blood flow in large arteries, impaired microcirculation, a change in the physicochemical properties of blood.

These three factors are a direct consequence of coronary disease.

An alternative to drug therapy for chronic lower limb arterial insufficiency and coronary disease is the use of photohemotherapy methods: extracorporeal UV irradiation and intravascular red blood irradiation (S.V. Moskvin, V. A. Builin. Methods of exposure to optical radiation during laser therapy. In the book: Low-intensity laser therapy. Proceedings. M., Technique, 2000, p.163-167).

However, all known methods of exposure to optical radiation on the blood have significant disadvantages:

1. The invasive method is quite traumatic and requires many additional conditions, these are preservatives for stabilizing blood coagulation (heparin), special cuvettes for irradiating blood, the method is sometimes accompanied by large blood loss in patients with "bad" veins;

2. Due to the wide spread of viral hepatitis and AIDS;

3. When a needle and a fiber are inserted into a vein, blood clots may occur around the fiber, damage to the vessel walls by optical radiation;

4. This method is contraindicated in patients with diseases such as hemophilia.

Closest to the proposed utility model is a well-known device for phototherapy of ischemic disease of the lower extremities, including rechargeable batteries, unit

control and radiation source - apparatus for laser blood irradiation "ALOK-1".

A device based on laser radiation, at first glance, has development prospects, but it is technologically complex and inefficient. Very expensive laser systems have extremely low efficiency with a non-invasive method of treatment for the treatment of ischemic disease of the lower extremities and are not used at all for its prevention. Such installations work more efficiently with intravenous exposure. However, in this case, they have all of the above disadvantages of invasive devices.

The conclusions of the founder of phototherapy of the Nobel laureate N. Finzen are that at the place of pressure on the biological tissue, the penetration depth of light increases tens of times, so the LEDs protrude 2-3 mm above the surface. Thus, increasing the efficiency of exposure to light can be achieved by additionally using the body weight of the person himself.

An increase in efficiency can also be achieved by the fact that, according to the first law of photochemistry, photochemical transformations can occur under the influence of the light that is absorbed by the substance.

Blue and green colors are the most active agents of optical radiation. They are absorbed by numerous endogenous chromophores, while causing regulatory mechanisms of the biological object, positively affecting blood viscosity, microcirculation and the homocoagulation system, which is crucial when using phototherapy devices to prevent the disease.

Red color plays the role of activator of volumetric blood flow and providing a “respiratory explosion” of neutrophilic granulocytes, which leads to retrodiffusion of H + ions, which damage the epithelium, causing the formation of blood clots in the capillaries. In the process of spontaneous thrombolysis, blood circulation is restored. This formed the basis for the use of red color of various wavelengths for treatment with the combined use of blue and green.

The simultaneous use of blue, green and red colors with different wavelengths of each color stimulates the peripheral blood supply system, while increasing the synthesis of cellular energy.

The technical task of the utility model is to create a simple device that uses the above effective methods of exposure to the human body, for the treatment and prevention of ischemic disease of the lower extremities

The technical result of the proposed utility model is to increase the effectiveness of the treatment and prevention of ischemic disease of the lower extremities, as well as to simplify the design of the device.

The specified technical result is achieved in that the device for phototherapy of ischemic disease of the lower extremities, including batteries, a control unit and a radiation source, is made in the form of a pair of slippers, each of which contains two batteries, a control unit and an orthopedic platform in the form of a foot with a built-in twelve light emitting diodes with radiation corresponding to wavelengths of 430-480 nm for blue, which is a radiation source representing 2-3 mm above the surface facing the foot go

colors, 500-530 nm for green and 660-720 nm for red, 4 LEDs for each color.

The proposed utility model uses a non-invasive method for the prevention and treatment of coronary disease of the lower extremities using various spectra of sunlight (blue, green and red) and different wavelengths of the same spectrum and additional mechanical action of the protruding LEDs due to the weight of the person himself.

It is preferable to use monochromatic light sources of superbright LEDs from Sharp (Japan) and Panasonic batteries (Japan) with a capacity of 2500 mAh.

Using batteries with a capacity of 2500 mAh will ensure the operation of the device for at least 50 hours continuously.

The proposed device consists of (Fig. 1: A - top view in the assembled state; B - side view in section; C - rear view in the assembled state): slippers for the feet (right or left) 1 with universal fastening (for example, with Velcro ) and a solid heel, preferably 50 mm high and nose, preferably not less than 15 mm, preferably made of plastic in the form of orthopedic shoes, with twelve LEDs 2, two batteries 3 and a control unit 4 with treatment programs installed.

The treatment programs include the use of various emission spectra, wavelengths and exposure times.

The platform of slippers and built-in 2-3 mm LEDs provide convenient use and easy sterilization after procedures for prevention and treatment in inpatient hospitals.

The device operates as follows:

On the control unit of each slipper (right, left), timer 5 sets the time (from 0 to 60 minutes), selects the spectrum color 6 buttons and presses and starts the program by pressing the "Start" button 7. After the procedure has expired, timer 5 turns off the LEDs. The patient removes the legs from the slippers and gives them for sterilization. In case of individual use of the device, sterilization is carried out if necessary.

The proposed device has the following advantages:

1. The possibility of effective treatment (through the use of LEDs with radiation corresponding to different wavelengths of blue, red and green) and prevention (through the use of blue wavelengths) of coronary disease of the lower extremities at home.

2. Due to the protruding LEDs by 2-3 mm and the weight of a person, the penetration of radiation increases several times, which increases the effect of phototherapy.

3. The device is easy to manufacture, cheap and easy to use, which allows it to be widely used by people of all ages.

4. Two rechargeable batteries in each slipper allow you to use the product for a long time before recharging.

5. Possibility of easy sterilization if necessary.
