Definitions

  • the present invention relates to a device and a method for disinfecting, in particular, hands.
  • Disinfectant solutions consisting of an aqueous ethanol solution in which the hands are washed are used by doctors. The solution drips off during washing and takes away substantial amounts of skin fat, which is why these disinfectants are suitable for regreasing, such as Wool wax alcohol included. In addition, solvents and odorants are used.
  • the washing process requires relatively large amounts of disinfectant, the majority of which runs unused.
  • JAP 071780001 (A) and JAP 6-54772 propose the use of sprayed sterilizing agents, but here too, much more liquid is consumed than is necessary for the actual disinfection, so that here too because of liquid running off the hands and being carried along loosened skin oil a regreasing, ie the addition of other chemical substances is required, which can lead to skin irritation or allergic reactions in long-term use.
  • the object of the present invention is therefore to provide a device or a method for disinfecting, in particular hands, in which the consumption of disinfectant can be drastically reduced while maintaining the full sterility effect, in which no amounts of liquid drip from the skin and where additions to the solution used can be dispensed with.
  • a device for disinfecting, in particular, hands consisting of a chamber and a nozzle arranged in it, which is connected via a line to a storage container and has a pump drive, and means for triggering the pump drive, in which, according to the invention, the chamber tubular with a closed rear wall and is accessible from the front.
  • the tubular chamber has an opening in which the nozzle is arranged, the nozzle being aligned with the central axis of the chamber, the diameter of the tubular chamber being approximately 180 to 220 mm and its length being approximately 200 to 250 mm.
  • the nozzle dispenses a fine-particle aerosol of the disinfectant and the pump drive can be adjusted so that between 0.5 and 1.5 ml of disinfectant are sprayed per disinfection process.
  • the mode of action is as follows. A defined small amount of aerosol is distributed from the nozzle into the chamber space, which is distributed relatively homogeneously and remains in suspension for a sufficiently long time at the low concentration according to the invention, so that the aerosol droplets also reach the back of the hand that is usually held down.
  • the aerosol droplets settle evenly on the skin surface, but without wetting, so that no liquid drips off. This process is caused by friction, i.e. supports a washing movement of the hands.
  • washing requires the removal of dirt, that is to say significant amounts of cleaning liquid run off, but hands to be sterilized have been washed beforehand.
  • the procedure according to the invention is advantageous in many respects.
  • the lack of draining or draining amounts of liquid means that the skin does not need to be re-greased, so that no additives have to be added to the 80% aqueous alcohol, since all liquid evaporates after use.
  • the chamber volume and the amount of liquid dispensed are coordinated. If the specified amount of aerosol in the chamber is exceeded significantly, this leads to undesired aggregation, ie drop formation and wetting.
  • the opening for the attachment of the nozzle is preferably located approximately in the middle and perpendicularly above the central axis of the drum-like chamber, since the washing movement for distributing the droplets naturally begins with the hand recesses which are open at the top and to which the nozzle is then directed.
  • Nozzles for the production of aerosols are known from the prior art, see. e.g. EP 0 593 900 A2. Opening diameters of 0.1 to 0.6 mm, preferably those of 0.2 to 0.3 mm, are used for the present purposes in order to deliver disinfectants with viscosities of about 1 to 1.5 [mPa-s] as aerosol can.
  • the intended effect of keeping the aerosol droplets suspended can be brought about by generating a potential difference between the chamber wall and the nozzle on the one hand and the human body or its hands on the other hand. Since humans are electronegative, particularly when grounded, it is proposed to apply a positive voltage to the nozzle and the chamber, wherein the nozzle has corresponding metal parts and the chamber made of plastic can be provided with a metal coating, for example in the form of a net or vapor deposition.
  • the disinfection must be finished at least without contact and preferably also be started.
  • the device on the chamber or its housing has switches with sensors. These are designed in particular in such a way that they only allow the aerosol to be dispensed again after the hands have been pulled out and / or after a time interval which is sufficient for complete evaporation, although it may be possible and prescribed to repeat the sterilization process, but the inventive method Benefits remain.
  • the device according to the invention can of course also serve other purposes, in particular additional nozzles can be provided for the application of liquid detergents or of skin care emulsions, but these then do not produce aerosols.
  • a floor drain is provided for draining liquids, the triggering of the desired function can also be done via sensors.
  • the chamber wall with a non-stick coating (polytetrafluoroethylene).
  • a heat radiation source can also be provided to dry the hands.
  • the mouths of the nozzles are preferably outside, in particular above the chamber wall or the associated openings. This allows the chamber to be pulled out of a housing for replacement or cleaning.
  • the method for disinfection according to the invention thus consists in producing an aerosol stream directed towards its central axis in a tubular chamber with an essentially circular or elliptical cross section of certain dimensions, in which the aerosol is distributed uniformly in the chamber and the hands are placed in this aerosol Wash movement disinfected.
  • Such an amount of aerosol is applied that droplet agglomeration does not occur in the chamber space and furthermore only such an amount of disinfectant is deposited on the skin that dripping or draining of liquid is excluded, i.e. that the disinfectant is removed from the skin by evaporation.
  • the amount of liquid is about 0.5 to 1.5 ml per sterilization process.
  • the disinfectant can be free of additives, but low-viscosity agents with e.g. Flavorings are used, e.g. Amphisept (brand of Bode Chemie Hamburg).
  • the present invention can also be used for the disinfection of feet.
  • the invention serves primarily for use in medical practices or hospitals, but it can also be used in food businesses where the sales staff touches the food (butchers).
  • the application can be carried out, for example, after every checkout, ie after touching banknotes known to be highly contaminated. Touching towels is also excluded. It is therefore also advantageous to use it in convenience stores; the use of hot air blowers for drying after disinfection, which can stir up germs present in the room, can thus be avoided.
  • Figure 1 shows a device in front view and Figure 2 such from above.
  • Figure 1 shows a section through the device seen from the front.
  • a housing 19 with a lid 15 there is a reservoir 10 with disinfectant liquid.
  • the container 10 rests on a spring 12 which presses it into a fastener and secures it.
  • a line 6 leads from the bottom of the container 10 to a nozzle 9.
  • the line 6 is connected to a pump drive 2, in which a valve 8 is arranged.
  • the container 10 can have any shape, the line 6 can also be guided through the bottom of the container.
  • a refill nozzle 23 for filling the container can be provided in the housing cover 14 below the cover 15.
  • the pump 2 initially delivers as much (disinfectant) liquid into a metering vessel 3 via the line 6 as is prescribed for the respective disinfection. This quantity can also be applied in several time periods.
  • a box 11 comprises the chamber 5.
  • the nozzle 9 and the pump 2 rest on the box 11, the nozzle 9 can protrude into the chamber 5 as shown, preferably it ends above the opening 25 around the drum-like chamber which is closed off by the rear wall 24 5 to be able to pull out.
