Abstract

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

The device consists of two blocks. The first is an autonomous device emitting with the help of an LED matrix, in the handle of which the power sources and the program control unit are located. The second is a stationary stand, consisting of a base, in which the adapter is located, which reduces the voltage and converts alternating current into direct current; the adapter is connected to the mains via a wire.

The base is connected to a flexible corrugated rod by means of a clutch. At the upper end of the rod there is a power plug that fits into the socket of the plug located at the lower end of the handle of the device. Both blocks are fastened together by a connector lock.

The device in its lighting capabilities surpasses all known devices used for the same purpose. Thus, the use of three-color light-emitting diodes significantly expands the boundaries of the therapeutic effect of the device: it is possible to use both monochromatic radiation and a combination of wavelengths, as well as their alternation.

Description

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

At present, phototherapy is widely used to treat various diseases, which allows, inter alia, to irradiate the body surface with optical radiation. At the same time, the most widely used devices are those emitting: UV rays, visible light, infrared radiation [1, 3], among which the Bioptron, devices for gas discharge lamps with a phosphor of blue and red light, laser and LED light sources are especially popular [3 , 2].

However, most modern optical range emitters have significant disadvantages. So, for example, the Bioptron phototherapeutic device (Zeptor company) emits linearly polarized electromagnetic radiation in the range of 400-2000 nm, which excludes the possibility of obtaining directed therapeutic effects that are highly dependent on specific radiation wavelengths. It is important to remember that the 1st law of photochemistry reads: “Photochemical transformation can occur only under the influence of that light that is absorbed by the substance.”

Monochromatic light sources — laser and LED irradiators — are more effective [3], although the limited emission spectrum accordingly limits the number of biological responses that entail therapeutic effects. For example, bilirubin absorbs in the range of 410-460 nm, which is the basis for the treatment of neonatal jaundice, red light λ = 630 nm is absorbed by porphyrins, and chlorins absorb light λ = 660-670 nm, which served as the basis for the photodynamic therapy of tumors. Thus, narrow-band emitters cause strictly limited therapeutic effects (except for general, characteristic for any range of optical radiation) [3].

The apparatus of the ASTP series (ASTP 4-1, ASTP 4-2, ASTP 4-3) was taken as the closest analogue [2].

The device of the ASTP type consists of a rectangular case in which a control panel is mounted on one side and a matrix of LEDs on the other; power is supplied from the network through an adapter with a step-down transformer and an AC to DC converter. The irradiated surface area is 6 cm ² , the apparatus weight is 1.2 kg. The devices of the ASTN series differ only in the range of light emission: ASTP 4-1 emits red light (λ = 655 ± 30 nm); ASTP 4-2 - green (λ = 520-540 nm) ASTP 4-3 - blue (λ = 430-450 nm).

The disadvantages of the apparatus used as the closest analogue are:

1. Each of the devices emits light of only one wavelength.

2. The device is powered only from the mains, i.e. It cannot be used in stand-alone conditions.

3. The shape of the apparatus (rectangular) is inconvenient for use; in some cases, does not allow the patient to use it independently.

4. The device is not convenient for a long-running procedure (for example, for the treatment of seasonal depression) because does not have a solid foundation.

The purpose of the utility model, which is, in fact, a technical result, is to create a device for irradiating the surface of the body, which has the ability to emit various wavelengths in the optical range, with the possibility of network and autonomous power supply, convenient in operation, both in medical institutions and at home . The goal is achieved by using a matrix of composite LEDs, each of which emits light of different wavelengths - red, blue, green with a divergence angle of 110 to 160 ° / SHARP microelectronics /.

A General view of the device in assembled form is presented in figure 1. The main part of the device is a matrix of 1 out of 12 composite

LEDs from Sharp (USA), capable of emitting light in three ranges: red, blue, green. The matrix is located in a round casing 2 made of plastic, which is connected to the handle of the device 4 by means of an interface tube 3; the handle 4 of the device, in turn, by means of a lock of the connector 5 is connected to a metal corrugated rod 6, coupled by means of a coupling 7 to the base 8.

The device actually consists of two blocks (figure 2).

The first (figa, B) is a stand-alone device emitting using an LED matrix 1, in the handle 4, which houses the power sources 9 and the program control unit 10.

The second (Fig.2B) is a stationary stand, consisting of a base 8, in which there is an adapter 11, which reduces the voltage and converts alternating current into direct current, the adapter 11 is connected to the mains through the wire 12. From the adapter 11, the wire 13, then going inside corrugated rod 6 to plug 14.

The base 8 is connected to the flexible corrugated rod 6 by means of a mounting sleeve 7. At the upper end of the rod 6 there is a power plug 14, which is included in the socket of the plug 15 located at the lower end of the handle 4 of the device.

Both blocks are attached to each other by a lock of connector 5 (Fig. 1).

The device in its lighting capabilities surpasses all known devices used for the same purpose.

The use of three-color light-emitting diodes significantly expands the boundaries of the therapeutic effect of the device: it is possible to use both monochromatic radiation and a combination of wavelengths, as well as their alternation. These light emission options are programmed and implemented using the program control unit located in the device. For example, monochromatic blue is used to treat desynchronosis, seasonal depression.

shine; for the treatment of liver diseases (cirrhosis, hepatitis), a two-color blue-green composition is desirable; for the treatment of secondary immunodeficiencies - the alternation of blue and red light, etc.

The treatment program is set by a doctor and can be implemented both in a medical institution and at home.

A stationary stand is necessary for long-term procedures (for example, in the treatment of seasonal depression or secondary immunodeficiency), and with its use it is also possible to use an autonomous power supply.

The first unit of the device is completely autonomous, which allows you to use it in any conditions, including field conditions.

The device operates as follows: the patient is in a sitting or lying position. The light-emitting matrix 1 of the device is installed at a distance of 30-40 cm from the irradiated surface of the body. The button starts the phototherapy treatment program, and the session begins. After its time, the device turns off.
