Description

METHOD AND DEVICE FOR DISINFECTING HOUSEHOLDING OBJECTS USING ULTRAVIOLETT RADIATION

The invention relates to a method and a device and its use in the household for the disinfection of objects. Furthermore, the invention is directed to a practicable method and apparatus for its use in dental offices, with which dental impressions and instruments used in dental practices can be disinfected. Also, the invention is directed to sanitation and disinfection in hairdressing and animal care facilities and veterinary practices, to provide a method and apparatus that enables the disinfection of implements and articles used in these areas. In private households there are bacteria, fungi, viruses and not least parasites that can harm humans. Impeccable hygienic conditions are the basic requirement of our health.

Furthermore, there are items that an increased germ or

Are exposed to parasite pollution. Examples include: animal care products, such as

Brushes, linen, etc.

Of particular importance are utensils that are used to nourish babies, as babies are particularly vulnerable due to their weak immune system.

The house dust mite allergy, triggered by the excretion products of the

Mites, of which about 500 different species are known, is often the cause of asthma. These parasites occur in private household preferably in carpets, clothing and especially in bed. There are people who are born due to congenital immune deficiency, acquired immune deficiency (eg HIV), a chronic illness (eg allergy), an acute illness (eg flu, gastrointestinal infection), cancer, transplantation, treatment With immunosuppressants, advanced age, etc. suffer from an immune deficiency / suppressed immune system and therefore have to put more emphasis on hygiene. From medical / dental practices, it is known to create hygienic conditions with great effort, with disinfectant in private households are rather the exception.

The disinfecting effect of UV radiation and microwave radiation is described in various publications. The UV disinfection is used, for example, in the cryostat of the company Leica, in operating rooms, water disinfection systems, room air sterilization systems, etc. commercially or industrially.

Closed disinfection devices for private households that work with UV, microwave rays and / or a combination of these two types of radiation are not known.

The use of disinfectant solutions is a possible method of sterilization. However, this is not unproblematic: the rising number of allergies is due to the excessive use of disinfectant solutions. An important role is played by the health-problematic formaldehyde due to resistance, contact allergies, environmental pollution and high operating costs.

No simple, workable solution has been found, as parasites, such as lice, fleas and ticks, can be meaningfully removed from clothing, brushes, etc. As far as the problem of house dust mite allergy is concerned, there are several recommendations: In addition to removing the carpets, frequent washing of bed linen and clothing is recommended. Signs of wear and tear, reduced "lifetime", detergent residues, high staffing costs and the associated costs are major disadvantages of these methods.

Bacteria, viruses (avian influenza), fungi and parasites can also be transmitted to animals from animals via animal care. examples for this are Ticks, fleas, featherlings, hair-pieces, lice, etc. These parasites are often hosts of dangerous diseases that can also be life-threatening for humans, eg. B. Infection of TBE by ticks. Mites have a special meaning in the private household: These are parasites, which can occur in the laundry, bed sheets and carpets etc. A subspecies are the house dust mites, whose excretions produce allergies and subsequently asthma. One third of the population suffers from allergic reactions. Another source of danger in the home is baby food items such as plastic or glass vials, silicone or latex or rubber teats, plastic and / or silicone pacifiers, rubber and latex. The existing solution is the uncontrolled decoction in a water pot or the temperature controlled decoction in a disinfection device (eg Nuk). By this method, the material properties change, evident in color changes: harmful material components could be absorbed by the baby. In addition, there is another problem: harmful germs that can not be killed with this method, eg. B.: Hepatitis C viruses, die only at 136 degrees. Other tasks arise from the fact that it makes perfect sense to disinfect contaminated bathroom, toilet and kitchen utensils: For example, the wooden board on which was stored (salmonella danger), cloths, dishwashing, etc. The need arises especially also in households where people living in a weakened immune system live: examples include transplant patients, HIV-infected people, old people, people with congenital immune deficiency, people who have a serious illness, but also people who have allergic to disinfectants. People who have an acute infectious disease also have an increased need for hygiene: for example, flu viruses, mumps, etc., it may be helpful to disinfect bedding, towels, handkerchiefs, clothing, etc. But also people who suffer from a chronic infectious disease: eg hepatitis.

The object of the invention is to provide a method and a device for disinfecting objects in households, dental practices and for companies, which is easy and inexpensive to use and by the application of the Procedure with a device is load-free for its operator.

The object is achieved according to the invention in that a household appliance having a closable housing uses at least one quantity of ultraviolet radiation to disinfect objects inside the housing.

This has the advantage that it is possible to dispense with disinfecting solvents with which one usually disinfects objects. Preferably, a plurality of radiation sources can be used in a housing for disinfecting the objects, in order to ensure that each object to be disinfected in the housing is fully exposed to the disinfecting radiation. Furthermore, it is possible to additionally use at least one microwave-emitting source for disinfecting the articles. This has the advantage that, in addition to the ultraviolet radiation treatment, these waves further disinfect a subject to be disinfected and, depending on the material of the object to be disinfected, increase the degree of disinfection and shorten the irradiation time.

The method for disinfecting in household areas to be used according to the invention provides in a closable housing a source which emits ultraviolet rays and wherein the rays are directed to the object or objects to be disinfected by scattering or reflecting the radiation and / or moving the source Housing encircles the or to be disinfected objects. On the one hand, such a method ensures that the objects intended for disinfection are also completely exposed to the radiation source and, on the other hand, this method ensures that the groups of people using the method are not exposed to any stresses. In addition, the method is inexpensive and easy to use, so that operating errors in the disinfection process of an object are excluded.

The inventive method is even more effective and effective to use when the intended for disinfection objects are additionally irradiated by means of microwaves. Microwaves can be disinfected In contrast to ultraviolet rays, articles penetrate to a greater extent and can assist or accelerate the disinfecting effect emanating from ultraviolet rays.

Improved, the inventive method can then be used if one uses for the disinfection of objects ultraviolet rays with different wavelengths, which are tuned to the object to be disinfected. It may be advantageous if the disinfection with ultraviolet rays and microwaves is delayed or at the same time depending on the use and selection of the objects to be disinfected.

In order to accelerate the disinfection of an article in a closed housing, it may be advantageous that the radiation source is moved in the housing during the irradiation and can thus irradiate different surface contours under different angular positions.

For safety reasons, it is advantageous and according to the invention imperative to carry out the irradiation exclusively when the housing is closed, so that the sources used for the irradiation can not be detected outside the housing or can only be detected in a safety area. The irradiation times are to be kept very short according to the invention and are advantageously matched depending on the selected wavelengths on the objects to be disinfected. It is possible to choose the irradiation times for a subject to be disinfected under ultraviolet irradiation and under microwave irradiation different.

In a household disinfection device produced according to the invention, at least one ultraviolet radiation emitting radiation source is provided in a closable housing, which irradiates one or more objects inside the housing. The housing of the household disinfection device is designed so that rays that can not escape to the outside, which are used for the disinfection of objects, as far as possible, regardless of their wavelength. The interior surfaces of the housing may have coatings that aid in the disinfection of articles to be disinfected in the devices. The source of UV radiation may be provided in an oven, refrigerator, freezer, washing machine or linen cupboard, and if necessary, this source of radiation may be activated. Depending on requirements, a plurality of radiation sources can be provided in the household disinfection device, which ensure the safe disinfection of an object. The radiation source or the radiation sources are arranged or aligned in the household disinfection device such that they completely irradiate the object to be disinfected or the objects to be disinfected. The radiation source or radiation sources can be arranged movably in the housing. In particular, they are movable by means of a motor drive.

In addition to the radiation source or sources which emit ultraviolet radiation, it is also possible for further radiation sources to be provided in the household disinfection appliance which emit microwaves simultaneously or with a time offset. Device versions are also conceivable in which one can choose between microwave irradiation or UV irradiation or a combined irradiation of an object to be disinfected. It may also be advantageous if the objects to be irradiated are movably held and / or mounted in the housing, wherein the object or objects can be moved or rotated by means of a motor drive.

According to the invention kits are also provided by ultraviolet rays and / or microwave emitting radiation sources for installation in existing household appliances, such as oven, refrigerator, freezer, washing machine, dryer, linen closet, so that devices existing in households can be easily and effectively retrofitted according to the invention.

In a figure of the drawing, a housing according to the invention is shown in a highly schematic manner with all functional features that can be operated with the method according to the invention. The device shown in the figure is to be understood as an example and does not limit the claimed inventive idea to a particular embodiment of a device. The FIG. 10 shows a household disinfection device according to the invention, which has a closed housing 12. To populate the housing 12 with objects to be disinfected, the housing is open and it can and must be closed before a disinfection treatment.

Inside the housing four ultraviolet radiation emitting sources 14, 16, 18, 20 are provided and it is in the household disinfection device 10, a microwave resonator 22, 24 is provided. On a grate 26, an object to be disinfected 28 is arranged, which is exposed to the radiation sources 14, 16, 18, 20 and on demand the microwave resonator 22, 24.

The grate 26 is designed to be rotatable if necessary, so that the object 28 placed on the grate can be set in a rotary motion. Also, if necessary, the sources 14, 16, 18, 20 may be movably disposed in the housing 12. The microwave resonator 12, 24 can be operated as needed together with the sources 14, 16, 18, 20 or separated from these sources 14, 16, 18, 20. The housing 12 may have a coating on the inner surfaces, which on the one hand supports a disinfecting effect for the objects to be disinfected in the household disinfection device and on the other hand, the walls of the housing 12 may be designed so that they are designed sound-absorbing and radiation-absorbing.

The device shown in the figure can also be used in the illustrated or in a modified manner in dental practices and / or in hairdressing shops.

The described device (Appendix 2) is also suitable for use with microwaves and the combined use of microwaves and UV rays to kill parasites, to reduce germs (bacteria, viruses, fungi, spores) on implements and materials and to dry them. The device can be used to kill parasites and reduce germs on implements and materials used by the hairdresser, pet grooming and / or veterinarian. Parasitic diseases such as the attack with head lice, mites, hairy leaves, Ferderlingen, ticks, etc. are very common. The fight against these parasites is extremely difficult. The drug treatment is expected to have significant side effects, also occur more often resistance. In kindergartens, schools, summer camps, etc. lice are permanent guests.

At the hairdressing and animal care facilities, the main focus will be on the parasite; at the vet, simultaneous disinfection of contaminated instruments is important. However, one can also imagine a situation in which it can come through infected brushes, combs, curlers, etc. to a transmission of serious diseases. About wounds on the scalp, pimples, infected hair roots, etc., bacteria, viruses, fungi can be transferred to the next customer. It seems essential that it is to be expected that these carriers of disease are primarily to be found at the ends of the bristles of the brushes and combs and the curlers.

Most hairdressers try to solve these problems by disinfecting spray solutions: However, these solutions and their application have serious disadvantages. It is hard to imagine that they will achieve the required effect. The aerosols formed during spraying can trigger allergies (as with all disinfectant solutions). They pollute the environment. They are expensive: purchasing, disposal, storage, administration, proper processing, etc. In case of improper treatment, they are dangerous (eye injuries, burns, etc.).

For these reasons, the hygiene requirements, for example, the hairdresser, the veterinarian and animal care facilities, even with regard to the self-protection for the practitioner, perceived as insufficient.

When disinfecting with UV radiation, it may be that an effect optimization is achieved in that the object to be disinfected is dried. This can be done by microwave irradiation. An example of this is when UV radiation is particularly important for the disinfectant effect, as is the case in medical practices and / or dental practices.

The objective and effect must be: sufficient killing effect on parasites such as lice, ticks, mites, hairy, suspension, etc., germ reduction in bacteria, viruses, and fungi, whereby the risk of infection is reduced, use of environmentally friendly technologies, personal protection of the user and drying effect.

According to the invention, the solution is by using microwaves to kill parasites and germ reduction, using a combination of microwave and UV radiation for germ reduction, devices that use these technologies and with which the objectives can be implemented, additional techniques and facilities to the Devices that cause an effect optimization, by special devices on the devices, the security is increased.

Especially the combined use of microwave and UV disinfection offers great advantages. Microwaves can successfully kill parasites even if they are in hard-to-reach areas, as is the case, for example, with the bristle catcher. Due to the disinfecting effect of the UV rays, the number of germs can be significantly reduced, the risk of infection decreases. In addition, the number of microbes can be reduced by microwaves.

A further advantage is the fact that a fast drying effect can be achieved by microwaves and this drying effect contributes to improving the effectiveness of the UV rays with respect to the disinfecting effect and reduces the risk of infection. In addition, the number of specific germs can also be reduced by microwaves.

For this reason, it may be advantageous that the UV irradiation is longer in time than the microwave irradiation.

It is the mode of action of the microwave that can be achieved by spraying the surfaces with water Impact optimization, since UV radiation Clear water can pass clear rays, their germicidal effect is not affected. By H ₂ O ₂ , the effect of UV rays can be optimized.

Protein coagulates at 56 degrees Celsius, and parasites, when heated to 60 degrees Celsius with microwaves, die. Since the effect of the microwave on water is particularly intense, the method described recommends that the instruments and objects are sprayed with water before being irradiated. UV rays can pass through clear water, so their germicidal effect is not affected.

Investigations in the context of the invention show that protein in a commercial kitchen microwave oven clots at 600 watts already after 9 seconds, at 360 degrees after 11 seconds and at 90 watts after one minute. All information is approximate.

If necessary, as the veterinarian, but also at the hairdresser can imagine, the disinfecting effect of UV rays should be exploited. This is ideally done by the combined use of UV radiation sources and microwave oven. The irradiation times may differ. Presets ensure easy handling.

However, as soon as the object to be treated is made of metal or microwave components are irradiated with metal components, care must be taken to ensure that no sparking occurs. This will also prevent the unit from being damaged.

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 completely immersed in a liquid preferably water, laid; this liquid is then brought to the required temperature. Here, one can also imagine a solution, such as a H ₂ O ₂ 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

Achieved advantages are: Safe parasite killing; reduced risk of infection through germ reduction; environmentally friendly process; Cost reduction: purchasing, administration, billing, warehousing, proper use, disposal; Personal protection of the user; no allergies; Drying effect.

The device according to the invention is characterized by simple handling by effect-optimized presets; shapely design is possible; Effect optimization through combined use of microwave and UV radiation; by optical or acoustic indications after irradiation; Safety shutdown and / or safety signal; Temperature display; Safety optimization by the fact that the irradiation takes place only in a closed device.

This device has devices which ensure that the objects to be disinfected and / or the objects to be killed by parasites are introduced in a defined manner to the microwaves and / or UV radiation source (s), the radiation being the maximum Efficiency offers. By way of example, guide rails, insertion shafts, locks, stiffeners, pivoting devices, etc. are listed. The device has a device that has a similar effect as a lightning rod. This is to prevent damage caused by sparking and overvoltage damage in the device. The device displays an optical and / or audible signal when the irradiation process is successfully completed. The device will indicate by an audible and / or visual signal if a fault occurs. The device has a temperature display or a temperature control. The irradiation process is started via switches, buttons, pushbuttons, etc. Different pre-set irradiation programs are operated by different control buttons, switches or similar. The device has a device that ensures that it can only be operated when it is closed. This prevents radiation from escaping. The device has a means of visualizing the kill-degermination process, for example, it could be through a transparent disc. The device has a device that allows spraying of the objects to be irradiated. For example, with water or a H ₂ O ₂ solution; This optimizes the effect. The device has one or more UV radiation sources. The device has one or more UV light sources and in addition a device that allows rotation and / or pivoting movement over one or more axes.

This application (3rd appendix) concerns indication areas, in which value is placed on a gentle, cost-effective sterilization. From various scientific papers, the sterilization by means of ultraviolet radiation is known. It is used successfully especially in the disinfection of drinking water. But even in hospitals, UV sterilization takes place in operating theaters. In addition, materials are sterilized with UV light that changes their material properties by conventional sterilization techniques such as hard blasting, heat, pressure, steam or chemicals.

The effectiveness of UV irradiation on bacteria should be based on those wavelengths of light absorbed by the nucleic acids. By the rays, the nucleic acids are changed so that an increase can no longer take place. In this case, UV lamps are preferably used which generate a strong radiation in order to keep the time of the irradiation as short as possible.

In medicine and dentistry, there are special requirements for hygiene. In early 2006 hygiene guidelines (RKI guidelines) were fixed for dental practices in the EU in order to achieve general hygiene standards. Part of these rules states that repetitive work processes must be defined "individually" in writing for each practice, and that these procedures must comply with RKI guidelines. In addition, a documentation obligation was fixed. The Federal Dental Association (BZÄK) and the German Working Group for Hygiene in the Dental Practice (DAHZ) have one Hygiene plan with operating instructions that describe the routes, equipment and materials that can be used to comply with the RKI guidelines.

In dental work, there are work processes in which materials or devices are used that are not optimally solved by the recommendations of BZÄK and DAHZ (see above).

Excerpts from the hygiene plan:

"Excerpt from the hygiene plan / operating instructions for the dental practice: Suitable disinfection procedures must be effective bactericidal, fungicidal and additionally limited virucidal (including HBV, HCV, HIV)."

"After each completed reprocessing (disinfection or sterilization) of medical devices, a release must be made for re-use.The release must be carried out by employees with approval authority and must be documented."

In the hygiene plan is under "impressions, dental workpieces": How: Either: spray disinfection in a closed system

(Cleaning and disinfection device) or: immersion disinfection. When: - immediately after removal from the mouth

- Impression after rinsing

- Dental workpieces before shipment to the dental laboratory

- Dental workpieces on receipt from the dental laboratory Who: Employees in the examination, treatment or maintenance area, employees in the dental laboratory / practice laboratory

Example 1: Impression taking:

After taking the impression, the hygiene plan recommends a disinfection with

Spray solution or dipping bath: The disinfecting solution used has serious disadvantages:

1. A chemical change of the surface can not be excluded. This can lead to surface changes that the Accuracy of the work can influence.

2. The use of these chemicals, including ordering, warehousing, purchase price is expensive. The use of chemicals involves a high level of financial and personnel expenditure on almost every working day. a. Administrative expenses for purchasing, warehousing, invoicing, control, possibly complaints; b. Effort of preparing the solution, checking, documentation of the proper use of the chemicals, training of the personnel; c. Disposal of this environment polluting chemicals and associated staffing; d. additional financial expense for protective clothing: eg protective gloves.

3. The use of these chemicals may cause sensitization and allergic reactions, damage to the health of the dentist, his staff and patients due to airborne aerosols or skin contact can not be ruled out.

4. The problem of the hospital germs is pointed out.

5. Environmental pollution from the disinfectants.

6. Increased risk potential in practice: These agents usually have caustic properties, which can harm people.

Example 2:

The prosthesis comes from the laboratory.

To ensure a complete hygiene chain, the work would have to be done before the

To be disinfected. A disinfection with spray solution can during

Patients on his well-perfused mucosa produce contact allergies.

There are no indications as to how the spray solution can be removed from the disinfected dental work in such a way that the patient will not suffer any damage to his or her health.

Example 3

Prosthetic repair:

The problem is similar to the problem with taking impressions.

Example 4 Consumables:

Examples of this are: swabs, biting rods and occlusion foils. Gutta-percha pins and plastic pens are bought in packs of 10: When you remove a peg, it always comes back to impurities. The remaining pens can not be sterilized satisfactorily by the types of disinfection described above.

The object of the invention is to provide a disinfection method and a disinfection device that simplifies the sterilization of equipment used in dental operations, impressions, dental work, instruments, etc. and minimizes costs

The disinfection with UV rays is a method in which the following disadvantages can be decisively improved:

1. UV sterilization is relatively inexpensive

2. No disadvantages due to chemicals: contact allergies, burns, etc.

3. No environmental impact

4. UV light does not cause any inaccuracies and surface changes that affect the passport accuracies.

5. No great human effort to provide a proper disinfection procedure for dental practices and dental laboratories.

Example 5 Rubber Polisher

Rubber polishers are used in the dental office z. B. used for polishing fillings and prosthetic work. The disinfection of these rubber polishers is difficult: the drill bath and other immersion baths attack the surface, in the rubber particles an air bubble can form, which influences the disinfection; If rubber particles are germinated in the sterilizer, then the material properties change and the polishers are no longer so durable.

Device, method / procedure for the disinfection of impressions in the dental practice and dental work, for the disinfection of equipment and instruments and for the disinfection of consumables, which are worse or more expensive to disinfect under heat, pressure, humidity or chemicals. These Disinfection is carried out using short-wave or ultra-short-wave light: UV radiation.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done by the use of one, two or more UV lamps or tubes, which are optionally mounted in a defined position, so that all surfaces of a body to be disinfected are fully illuminated or irradiated. These UV lamps can - if necessary - also be diverse, d. H. they can also produce UV rays of different wavelengths.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done through the use of tools for focusing, scattering, focusing, refraction, transmission, reflection, diffraction, absorption, deflection, amplification or attenuation of the rays from UV lamps or tubes. These aids can be: z, B.: light guides, lenses, glasses, light amplifiers, mirrors, grids, aperture, etc. Parabola-shaped mirrors appear particularly advantageous.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done by the use of inserts which ensure a reproducible position of the objects to be disinfected (eg: predetermined contact surfaces, which are simulated to the contour of the objects to be disinfected so that all surface parts of the objects can be irradiated sufficiently intensively and in time ). Another example is the special drill stands, which can be inserted into the device with precision, thus achieving optimal illumination / disinfection.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done by using one or several light sources, which rotate around the object to be disinfected. The speed depends on the required illumination duration.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done by using a device / device that causes rotation of the objects to be disinfected. All items can - if necessary - automatically rotated in the device, moved, and / or pivoted so that the support surface of the objects changed during disinfection in the device.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done through the use of mirrors, grids and apertures to prevent shadows from forming and changing the desired wavelength of the "UV light".

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done by using mirrors and apertures that are at a certain angle to each other. This is to avoid shadows, increases, reductions in the wavelength.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done by using an air conditioner, in the sense of a dehumidifier or humidifier and / or by using a refrigerator / heater or a fan, which are controlled by a thermostat or sensor, and ensure that the temperature does not change uncontrollably.

Disinfection is carried out in a device that ensures optimum illumination of the impressions, dental work, instruments, equipment and materials to be disinfected. This is done through the use of built-in / built-in devices, in the sense of a timer, possibly coupled with light barriers for switching on / off, in which the irradiation duration is fixed or can be freely selected. If legal requirements stipulate a minimum irradiation time, this time can be set so that this time is not undershot.

The disinfection is carried out in a device which, through the use of a photocell or a switch, ensures that the UV lamps or tubes are switched on only when the device is closed, thus precluding the operator from having to use the device UV light is damaged.

The disinfection takes place in a device that works optimally by a preset number of pulses or by a number of pulses that can be varied by the operator. A corresponding device on the device allows this. If legal requirements stipulate a minimum number of pulses, the device can be preset in such a way that this minimum number of pulses can not be undercut.

The disinfection takes place in a device that has an insert for removal, which can also be cleaned outside the device. This insert preferably has an ozone collecting container.

The disinfection takes place in a device that has an insert for removal, which can also be cleaned outside the device. This insert preferably has an ozone catcher. This insert preferably has a device which makes it possible to safely extract any possibly arising ozone (eg in combination with a non-return valve).

The disinfection is carried out in a device which additionally has a device which uses the ozone produced for disinfection, in addition to the disinfection with UV light. Example: fan.

The disinfection takes place in a device, which additionally has a device for disinfection documentation. In addition, operator, date, etc. can be entered. If, by means of binding guidelines, irradiation times or radiation intensities or a duration of time related to an object to be disinfected are specified, these parameters can not be changed with respect to the object to be disinfected.

The disinfection takes place in a device which additionally has a device which indicates by an optical and / or acoustic signal, if the disinfection process was too short.

The disinfection takes place in a device which additionally has a device which indicates by an optical and / or acoustic signal when the irradiation process / disinfection process is completed.

The disinfection takes place in a device in which a measuring device is additionally installed, which indicates by an optical and / or acoustic signal when the irradiation intensity is insufficient.

The disinfection takes place in a device in which a meter is additionally installed, which indicates by an optical and / or acoustic signal when the ozone concentration is excessive.

The disinfection takes place in a device in which an additional device for generating an air flow is installed. The aim of this device is to blow water drops, saliva drops, blood droplets, etc. This ensures that the required penetration depth for the UV rays is reduced, thus optimizing the disinfection process. This air flow can be preheated in conjunction with the heat generated by the UV lamp or UV tube, or by an additional heater to additionally achieve drying of the objects to be disinfected. The air flow can be generated by devices such as compressor, blower, fan, etc.
