Description

LIGHT BANDAGE.

The utility model relates to medical equipment, namely to physiotherapeutic units that use the energy of electromagnetic radiation.

Over the past 20 years, low-energy radiation in the red spectral region has been used to treat festering wounds, trophic ulcers, inflammatory and degenerative joint diseases. For this purpose, various types of therapeutic units based on a low-energy helium-neon laser are used.

Known light-beam dressing (application of France N 2592798, MKI A 61 N 5/06, 1987), containing a flexible elastic base (in the form of fabric or film) with a large number of optical fibers with open ends evenly spaced on the surface of the dressing so that the dressing emits light evenly over a large area. This device has an inconvenience in operation. For the effective introduction of light into optical fibers, it is necessary to have an additional complex optical radiation input device. In addition, the impossibility of a sharp bend of the fibers causes additional difficulties in operation.

The task is to simplify the design.

The task is achieved by using a matrix of semiconductor light-emitting diodes as a light source, mounted in an elastic flexible plate with a density of not more than one fiber per 0.3 square cm.

In FIG. 2 shows an electrical diagram of a light beam dressing.

The device consists of a plate 1 4-8 mm thick made of an elastic material (for example, silicone rubber)) in which semiconductor light-emitting diodes 2 of type U106A are hermetically mounted, connected in parallel with an electric circuit and powered from a constant current source 3 with a voltage of 2V. Semiconductor diodes emitting red monochromatic light (660 +. 10 nm) are located at a distance of at least 0.3 cm from each other, which at an angle of radiation of 60 allows you to create a uniform light spot with a light flux power of 30 MW, which allows you to penetrate soft tissue to a depth of 50-60 mm.

The front light-emitting surface of the device is covered with a transparent PTFE film 4, which ensures diffuse radiation, the tightness of light-emitting diodes and allows all types of cold sterilization.

The luminous flux area depends on the size of the matrix and can be changed, in accordance with specific tasks.

The device works as follows: a gauze cloth moistened with saline is applied to the affected surface. The surface of the light-beam dressing is wiped with ethyl rectified alcohol and easily pressed to a gauze napkin. The device is fixed with a gauze bandage or adhesive tape, then connected to a power source. Power supply 3 is included in the power supply network 220V / 50Hz, the output voltage of the power supply is 6V DC, the operating current is 0.2A.

The applied voltage causes the radiation of the matrix of light emitting diodes 2. The exposure time is determined by the required dose of radiation, which is set in accordance with the treatment methodology.

The cost of a light-emitting diode at the same radiation power is three orders of magnitude lower than the cost of a laser, the supply voltage of 2V is completely safe, the diode resource is almost unlimited - 25,000 hours. The area and configuration of the matrix can be changed depending on specific requirements.

Light beam dressing, unlike the prototype, does not require a special room for use and can be superimposed in the ward. Acceptable and home use.
