Definitions
- the present invention relates to a method and a device intended to ensure the disinfection of technical premises, in particular in hospital establishments (operating theaters etc.), retirement establishments, in communities (educational establishments, nurseries, etc.) and in installations in the agro-food industries (canneries, farms, etc.) by spraying disinfectant solutions.
- the devices currently marketed for such an application include a nozzle for spraying the disinfectant composition, generally consisting of a solution with or without formalin.
- a nozzle for spraying the disinfectant composition generally consisting of a solution with or without formalin.
- the nozzle clogs up due to deposits which accumulate there, these deposits resulting in particular from the polymerization of the constituents of the disinfecting solution. It is therefore necessary to regularly clean the nozzle or even to replace it, which leads to an uneconomic loss of time due to the unavailability of the premises which results therefrom.
- the disinfection devices produced at present are not suitable for disinfecting large technical rooms, which are encountered more and more frequently, especially in modern hospitals where there are technical platforms comprising 4 to 5 operating rooms whose total volume can be around 500 m 3 , while the maximum capacity of existing disinfection devices does not exceed 150 m 3 .
- the periods of immobilization of the existing devices, necessary for cleaning or replacing the spray nozzles do not make it possible to ensure the speed required now for disinfection, this requirement arising from the need to reduce to a minimum the periods of non-use of technical premises such as operating theaters.
- the present invention has therefore set itself the objective of providing a method and a device for disinfection which does not have the above-mentioned drawbacks of devices according to the prior art.
- this invention relates firstly to a method of disinfection by spraying a disinfectant composition using a nozzle, characterized in that it consists in successively spraying, through said nozzle, said disinfectant composition, then a rinsing composition ensuring self-cleaning of said nozzle.
- the rinsing composition comprises from 0.05 to 10% by volume of quaternary ammonium, from 0 to 5% of propanol-2, from 0.02 to 5% of a nonionic surfactant, the rest being purified water.
- the invention secondly relates to an automatic device for implementing the method as specified above. This device is characterized in that it comprises:
- a turbine positioned above the spray nozzle in order to ensure diffusion and mixing in the air of the sprayed composition
- this device is provided with a remote control which makes it possible to ensure control from a location located outside the enclosure to be disinfected.
- this spraying device is in the form of an autonomous unit mounted on swivel casters enabling it to be positioned in any desired location.
- this device comprises two storage tanks, 10 and 12, intended respectively to receive the disinfecting composition and the rinsing composition which must ensure self-cleaning of the spray nozzle 14, with which this device is provided. known manner.
- the disinfecting and rinsing compositions are delivered to the nozzle through a conventional system of solenoid valve 16, compressor 18, and pump 20.
- this device there is provided, under the spray nozzle 14, a turbine 22 driven by an electric motor 24.
- the assembly constituted by the turbine and the spray nozzle 14 is positioned in an enclosure 26 open only at the top of the device. Thanks to this arrangement, the sprayed composition (disinfectant and self-cleaning) is mixed and distributed in the air, which in particular makes it possible to improve the effectiveness of the disinfection by obtaining high humidity.
- the device is also provided with a microprocessor making it possible to carry out all the functions of the device so that the user is kept informed, in real time, of the progress of each stage of disinfection.
- the device is preferably provided with a remote control allowing the user to start up this device outside the enclosure to be disinfected, thereby improving safety of use.
- this device operates according to successive sequences of two stages: - a disinfection stage during which the spray nozzle
- the device according to the invention can be used with any disinfection compositions currently known.
- a disinfectant composition can be used consisting of a mixture of germicides chosen from the following families:
- aldehydes formaldehyde, glyoxal, propionaldehyde, butyraldehyde, glutaraldehyde, etc.
- - aliphatic alcohols ethanol, methanol, propanol, butanol etc.
- - polyalcohols methylglycol, ethvieneglycol, propylene glycol, butylglycol, etc.
- a disinfectant composition containing less than 3% by volume of formaldehyde can be used.
- composition can be used:
- - tertiary butyl alcohol from 0 to 20%, preferably 2%; - ethanol from 0 to 20% and preferably 7%;
- - thymol from 0 to 5% and preferably 0.5%
- the invention proposes the following formula:
- - quaternary ammonium from 0.05 to 10% by volume, preferably 1%;
- - propanol-2 from 0 to 5% and preferably 0.3%;
- - nonionic surfactant from 0.02 to 5%, preferably 0.1%; - purified water: supplement.
- the device according to the present invention brings in particular the following advantages: - possibility of using formalin-based compositions without damaging the electronic equipment present more and more often in the enclosures to be disinfected (in particular operating theaters), which was not previously not possible with known devices;
- the disinfection capacity of the device of the invention is 50 to
- the device of the invention thanks to its accelerated diffusion by turbine allows to save up to at least two hours compared to the devices according to the prior art;
- the official approval control of such devices leads to verification that the contact time recommended by the manufacturer for the surfaces to be disinfected corresponds to the desired microbial destruction.
- This contact time depends closely on the quantity of disinfectant product released during the first phase of the process.
- Tests relating to a device which is the subject of the invention in order to determine the number of milliliters per cubic meter necessary for obtaining the result wanted, allowed to keep over time the same calibration of the perforations of the nozzle, that is to say the same quality of disinfection, while with the devices according to the prior art, the nozzles are blocked gradually until complete failure, which results in the fact that disinfection is no longer ensured well before the final failure.
