Definitions

  • the invention relates to a disinfectant.
  • the invention relates to a method for sterilizing rooms, a device for carrying out the method according to the invention and a system for the sterilization of rooms.
  • a soil germination is performed by closing the space to be sterilized, in particular sealed, and then fumigated. After a predeterminable exposure time of, for example, two hours, the room is considered sterilized. Due to the aggressiveness of the disinfectant used, which usually has comparatively high concentrations of chlorine-containing compounds or ozone, people must not be in this room during the exposure time. After completing the sterilization, ventilate the room to remove the gas used. Then the room can be entered again by people.
  • the disadvantage of this approach is that with the airing and with the entry of people into the room a re-germination takes place. This re-germination takes place so fast that within a very short time the germ status is restored, as it existed before the sterilization.
  • an injection device which is suitable for introducing disinfectants and / or fragrances in a flow of a line system.
  • the agents preferably in liquid form
  • an injection head is provided, which can be designed in particular as a nozzle and particularly preferably as a hollow cone nozzle.
  • the injection takes place here at intervals.
  • the disadvantage of this is that in the interval pauses in which no fumigation takes place, a recontamination occurs.
  • a permanently safe sterilization is achieved and a recontamination effectively avoided.
  • the duration of the process is arbitrarily long in terms of time, without the need to interrupt the intended use of the space or area to be sterilized.
  • a continuous killing of pathogenic, unhealthy or similar germs is hereby achieved and prevents recontamination for the duration of the method used.
  • said germs include bacteria, viruses, fungi, spores, fine dusts and the like.
  • a successful continuous process management for sterilization depends on the synergetic interaction of individual features essential to the invention.
  • the method according to the invention can be used in a large number of fields.

  • AGW legal occupational exposure limit
  • the respective lower limit value is preferably adhered to. This is particularly the case in the food industry, where both occupational exposure limits and food hygiene regulation (LMHV) limits apply.
  • the total concentration of the disinfectant in the aerosol is chosen so that the individual concentration of both the oxidizing agent and the surfactant are below such a limit.
  • Spatial germination methods known from the prior art typically make use of concentrations which are significantly above the prescribed limits in order to be able to realize sterilization at all.
  • the prevailing opinion in the prior art is therefore that for proper sterilization comparatively high concentrations of active ingredients must be used that are harmful to humans, animals, food and the like.
  • the invention proposes here in deliberate departure from the prior art, a new way.

  • the total concentrations used are thus significantly below the AGW of suitable for the formation of the disinfectant according to the invention oxidizing agents such as in particular, sodium hypochlorite (0.5 ml / m 3 ), hydrogen peroxide (0.5 ml / m 3 ), ozone (0.1 ml / m 3 ) or peroxyacetic acid (10 ml / m 3 ).
  • oxidizing agents such as in particular, sodium hypochlorite (0.5 ml / m 3 ), hydrogen peroxide (0.5 ml / m 3 ), ozone (0.1 ml / m 3 ) or peroxyacetic acid (10 ml / m 3 ).
  • the total concentrations of the disinfectant in the aerosol are well below those for dust in general and for surfactants in particular AGW of about 10 ml / m 3 .
  • the aerosol used for sterilization is thus not only harmless to humans but also effective against germs and does not affect in any way the intended use of the space to be sterilized, whereby the inventive method provides by its continuous application for an initial sterilization and beyond a resuspension prevented in an advantageous manner.
  • the inventive method can thus be carried out continuously without consideration of people present in the room.
  • a recontamination, as occurs in the known from the prior art method can be advantageously avoided with the inventive design, so that in the space to be sterilized even with the introduction of fresh germs in said space, for example by ventilation, a constantly low Germ level can be maintained.
  • a suspended aerosol is generated from the disinfectant.

  • the ambient air is not or not suitable as such for the generation of the aerosol or for other reasons can not be used as a carrier medium, this is particularly advantageous.
  • Floating ability of the aerosol is advantageous because it improves the distribution availability of the aerosol.
  • the disinfectant is therefore sprayed according to a preferred embodiment of the invention to fine droplets with a diameter below 10 pm.
  • a buoyant and stable aerosol can be produced in this way. It has also been found that droplets with such a diameter, in particular in the case of structured and / or porous surfaces, as occur in particular in the case of textiles, lead to particularly effective sterilization due to improved material handling. To further improve material handling, it is preferred to produce droplets with a diameter below 5 pm and more preferably between 1 pm and 3 pm.

This results in a whole series of advantages. On the one hand, any effects associated with aerosol production, such as, in particular, a perceived unpleasant noise development in the space to be sterilized are imperceptible. This is particularly beneficial in the hospital where people who are in need of rest are typically treated. On the other hand, the device is also optically not present in the space to be sterilized, whereby the appearance of the room is not unduly disturbed.
