Description

Hand-held irradiation device

The invention relates to a handheld irradiation device for the application of electromagnetic radiation.

Light quanta and magnetic radiation are absorbed by human tissue and can support or stimulate a healing or growth process. The electromagnetic waves are (partially) absorbed by the tissue or cells and can cause a corresponding desired reaction.

There are different absorbers or photoacceptors in the human body for different wavelengths. Accordingly, the excited cells can be selected based on the wavelength and thus the color of the light - at least in the visible frequency spectrum. The depth of penetration of the photons into the tissue depends on the number of absorbers for the specific wavelength on the path of the light beam through the tissue. Wavelengths in the near infrared range penetrate the tissue to a depth of several centimeters.

Tissue has good transmission, particularly in the near-infrared wavelength range between 700 nanometers (nm) and 900 nm. Below 700 nm there is intensive hemoglobin absorption in the skin and above 900 nm there is strong absorption of water stored in the tissue or incorporated into the cells. The range between 700 and 900 nm is therefore also referred to as the bio-optical window. Since the proportion of absorption decreases sharply, but the scattering of the electromagnetic waves remains relatively the same even at deeper penetration depths, near-infrared light can reach a penetration depth of up to several centimeters in the tissue. This means that deeper tissue structures can be stimulated by the absorption of photons.

In order to achieve the full benefits of the treatment, each cell should be exposed to the same composition of light rays. This should also be the case if several individual light sources with individual spectra are used ^, with the individual light sources arranged next to one another.

The object of the invention is to provide a handheld irradiation device that is easy to handle, works reliably and is inexpensive to manufacture and in which electromagnetic radiation from several light sources can be emitted homogeneously.

This object is achieved by a handheld irradiation device for applying electromagnetic radiation according to claim 1.

The invention proposes a handheld irradiation device for applying electromagnetic radiation, with a controllable light source field emitting light waves, in which individual light sources with different emission spectra are each combined into groups, wherein the groups have light sources with different emission spectra from one another, wherein the various light sources of each group are arranged geometrically in the same way to one another and the groups are arranged next to one another in a repetitive manner, wherein the light sources of each group are arranged in a square ("squared arrangement").

A particularly advantageous and therefore preferred embodiment of the invention provides that a controllable magnetic field source is provided for generating a magnetic field. By applying magnetic fields to tissue, supplementary or additional positive effects are achieved in the tissue through stimulation or healing. Even weak magnetic fields noticeably improve the absorption of calcium in bones.

Furthermore, under the influence of low-frequency magnetic fields, bone cells produce more building blocks for bone growth. Osteoblasts produce more collagen, which is the main protein in bones. This is needed more for healing after bone fractures. The production of collagen can be increased in this way.

It is advantageous to use light-emitting diodes as light sources. These are particularly low-loss, long-lasting and maintenance-free, which makes them ideal for this task.

A further development of the invention provides that the four

different LEDs in a group an emission

wavelength of essentially 660 nm, 680 nm, 730 nm and 880 nm.

Near infrared wavelengths are able to accelerate wound healing. Light rays with wavelengths of 680 nm, 730 nm and 880 nm have been tested and found to be particularly beneficial.

Another selection of light sources involves selecting LEDs with an emission wavelength of essentially 370 nm, 470 nm, 660 nm and 680 nm in a square arrangement. This mixture is particularly beneficial for skin diseases, as the short-wave portion is effective against infections and bacteria.

DNA synthesis was increased many times over using LEDs with wavelengths in these ranges. The special wavelengths are absorbed by the mitochondria in the body's cells and have a stimulating effect on energy metabolism (adenosine triphosphate (ATP) metabolism).

Coil 41 of a handheld irradiation device according to the invention (Fig.

L ₂ , L3, L ₄ see Fig. 4). The individual light sources 21 of the ;

Light source field 2 have different emission spectra and are arranged into groups 3.

The exact arrangement of the individual light sources 21 is shown in j

Fig. 2 explained in more detail. j

So that the entire emitted light mixture of the different !

as homogeneously as possible on or in human tissue in particular j

In order to be able to apply the different types of light sources that occur in the light source field, they are grouped together in a group.

In the example, light sources 21 in the form of LEDs with emission wavelengths around 660 nm, 680 nm, 730 nm and 880 nm are arranged in the light source field 2. According to the invention, these four types are arranged in a square. So, as shown in group 3, they are arranged in a square (the numbers 660, 680, 730 and 880 stand for the arrangement of a light source with a corresponding emission spectrum). This group is arranged symmetrically next to and below each other. This can be 3x3 as in the example in Fig. 1 or 5x4 as in Fig. 2 or any other surface arrangement.

However, the light sources 21 of a group 3 are always square

2062 G

This means that the light is emitted as homogeneously as possible, since only one position (one light source) is offset in the grid, resulting in the arrangement of a squared group 31 arranged in a rectangle. V--''

LEDs as light sources have the advantage that they produce very little waste heat and have a very long service life of around 100,000 operating hours. Furthermore, the selective emission spectrum of LEDs is very well suited to providing the advantageous emission maxima mentioned (660 nm, 680 nm, 730 nm and 880 nm).

Another selection of light sources involves selecting LEDs of type 370 nm, 470 nm, 660 nm and 680 nm in a square arrangement.

For special light beam treatments, a further light source 22 can be provided centrally in each squared group 3 of light sources 21 in a squared arrangement with the properties described above according to Fig. 3.

The central light source is also an LED with a wavelength spectrum between 370 and 470 nm. When applied to human tissue, this ultraviolet and blue range results in the generally produced free radicals being reduced. This causes what is known as photorepair, which only occurs when the body cell is briefly irradiated with violet light.

i.e. the four different light emissions L ₁ , L ₂ , L3 and L ₄ as well as the magnetic field B are shown.

The magnetic field source 4 and the light source field can also lie in planes parallel to each other and not only, as shown, in a common plane E.

The light source field 2 - and in the example also the magnetic field source 4 - is controlled according to a fixed control pattern, i.e. its emitted light output/magnetic field output is controlled.

In Fig. 5 a control pattern of the magnetic field source is shown in more detail

explained.

The magnetic field source is controlled with pulses grouped together with a repetition frequency of 20 Hz each.

Shown is a group with positive impulses 64 over

the time t.

This causes an emission of a rectified pulsed magnetic field B.

In the example, the light source field is also controlled synchronously with the pulses of the magnetic field source.

Another control pattern provides that the pulses are clocked with a repetition frequency of 1200 Hz. This has another, equally positive effect on the tissue being treated.

Between the pulse groups of 20 Hz and 1200 Hz, a 20-second break without light wave and magnetic field emission is provided.

The head parts can have different shapes and light source field sizes for different application locations on or in the human or animal body. For example, an oral cavity applicator with only one group of LEDs is conceivable, whereby a small coil can again be arranged around the light source field.

The power source can be a battery supply provided in the fuselage or an external power supply. 10
