Description

General problem and how this Problems solved today become:

Parasitic diseases like the infestation with head lice Mites hairpieces, Ferderlinge, ticks ... are very common. The fight This parasite is extremely difficult. At the medicinal Treatment is expected to have significant side effects, moreover occur more frequently Resistances on.

In Kindergarten, schools, summer camps ... lice are permanent guests.

At the Hairdressing and animal care facilities will be the main focus the parasites lie, at the vet is a simultaneous disinfection of contaminated instruments important. However, you can also quite imagine a situation in which it is infected by To brush, combs, Curlers ... to a transfer can come from serious illnesses. About wounds on the scalp, pimples, infected hair roots ... can Bacteria, viruses, fungi are transferred to the next customer. It seems essential that it can be expected that this disease carrier especially at the ends of the bristles of the brushes and combs and the curlers to look for.

• 1. Es ist kaum vorstellbar, dass sie die erforderliche Wirkung erzielen.
• 2. Durch die sich beim Sprühen gebildeten Aerosole können Allergien ausgelöst werden (wie alle Desinfektionslösungen
• 3. Sie belasten die Umwelt.
• 4. Sie sind teuer: Einkauf, Entsorgung, Lagerhaltung, Verwaltung, sachgerechte Verarbeitung ....
• 5. Bei unsachgerechter Behandlung sind sie gefährlich. (Augenverletzungen, Verätzungen ...)

Most hairdressers try to solve these problems by disinfecting spray solutions:
However, these solutions and also their application have serious disadvantages:

• 1. It is hard to imagine that they will achieve the required effect.
• 2. The aerosols formed during spraying can cause allergies (like all disinfectant solutions)
• 3. They pollute the environment.
• 4. They are expensive: purchasing, disposal, warehousing, administration, proper processing ....
• 5. If handled improperly, they are dangerous. (Eye injuries, burns ...)

One Another disinfection attempt is made with UV radiation: this Hold the device we for different reasons for poor. There is, according to our knowledge, no sufficient proof that kills parasites with it also prevent technical equipment and shadow formations a sufficient germ reduction.

Our problem:

Out these reasons For example, the hygiene requirements for the hairdresser, the Veterinarian and in animal care facilities, also with regard to Self-protection for the practitioner, perceived as insufficient.

at The disinfection with UV radiation can be an effect optimizing is achieved by drying the object to be disinfected becomes. This can be done by microwave irradiation. An example for that is, if in the UV irradiation special emphasis on the disinfecting Effect is placed, as in medical practices and / or dental practices the case is.

Objective, effect:

• 1. Sufficient killing effect on parasites such as lice, Ticks, mites, hairy leaves, featherlings ...
• 2. Germ reduction in bacteria, viruses, and fungi: thereby the risk of infection is lowered.
• 3. Use of environmentally friendly technologies
• 4. Personal protection of the user
• 5. drying effect

our solution

• 1. Use of microwaves to kill parasites and for germ reduction
• 2. Using a combination of microwaves and UV radiation for germ reduction
• 3. Devices who use these technologies and with whom the objectives can be implemented.
• 4. Additional Techniques and equipment on the devices that optimize their effects cause
• 5. Safety is increased by special devices on the devices.

Just the combined use of microwave and UV disinfection offers size Advantages. Through the microwave can Parasites are also successfully killed when they are in hard to reach Stop areas such as the bristle mount the case is. Due to the disinfecting effect of UV rays The number of germs can be significantly reduced, the risk of infection sinks. In addition, the number of microbes can be reduced by microwaves.

a Another advantage we see in that microwave is faster Drying effect can be achieved and this drying effect to improve the effectiveness of UV rays in terms of disinfecting Effect contributes, the risk of infection decreases. In addition, also by microwaves Number of certain germs are reduced.

Because of this, it may be beneficial that the UV irradiation is longer in time than the microwave irradiation.

It is due to the mode of action of the microwave that by spraying the surfaces With water impact optimization can be achieved because of UV rays clear water can happen becomes their germicidal Effect not affected. H2O2 optimizes the effect of UV rays.

Protein coagulates at 56 degrees Celsius and parasites when using microwave on one Temperature of 60 degrees Celsius are heated, die. Because the The effect of the microwave on water is particularly intense, recommends the method described that the instruments and objects before the irradiation with water sprayed become. UV rays can Clear water, so its germicidal effect is not impaired (drinking water disinfection).

own Studies show that protein in a commercial Kitchen microwave oven at 600 Watt already clotted after 9 seconds, at 360 degrees after 11 seconds and at 90 watts after a minute. All information is approximate

Wikrowelle Although has a germicidal effect on certain germs, but not all relevant germs die in the time off, for a sufficient disinfection makes sense.

Therefore should in case of need, how to do that at the vet, but also at Hairdresser can imagine the disinfecting effect of UV rays exploited become. This is ideally done by the combined use from UV radiation sources and microwave oven. The irradiation times can be differ. Presets will make handling easy secured.

Technical problem:

As soon as but the object to be treated is metal, or metal components must be irradiated with microwave, it must be ensured that it is too no sparking comes. This also avoids that Device is damaged.

Solution:

• 1. Der metallische Gegenstand wird teilweise in eine Lösung gelegt die dafür sorgt, dass es keine Funkenbildung gibt. Auch Wasser eignet sich dafür.
• 2. Durch einen „Metalldetektor" erkennt das Gerät, dass metallische Bestandteile bestrahlt werden sollen. Ein Signal gibt diese Information dann in geeigneter Weise weiter.
• 3. Der zu behandelnde Gegenstand wird vollständig in eine Flüssigkeit, vorzugsweise Wasser, gelegt, diese Flüssigkeit wird dann auf die erforderliche Temperatur gebracht. Hierbei kann man sich auch eine Lösung vorstellen, wie zum Beispiel eine H2O2-Lösung oder eine Nanosilber-Silberwasserlösung. Durch spezielle Beschichtung der Einsätze, in denen die Gegenstände behandelt werden, kann die abtötende- bzw. die keimreduzierende Wirkung verstärkt werden.
• 4. Blitzableiter

There are several ways to do this:

• 1. The metallic object is partially placed in a solution that ensures that there is no sparking. Also water is suitable for it.
• 2. Through a "metal detector", the device detects that metallic components are to be irradiated and a signal then passes this information on in a suitable way.
• 3. The object to be treated is placed completely in a liquid, preferably water, this liquid is then brought to the required temperature. Here, one can also imagine a solution, such as a H2O2 solution or a silver nanosilver solution. By special coating of the inserts in which the articles are treated, the killing or germ-reducing effect can be enhanced.
• 4. Lightning rod
