Decontamination method and system implementing it
View Patent ↗The method of microbiological decontamination of a machine comprising an enclosure for treating a support and a conveyor comprising a shuttle, comprises the steps of obtaining a container adapted to be received on the shuttle and to diffuse biocidal agent in the enclosure, of placing the container on the shuttle, of moving the shuttle within the enclosure, and of evacuating the agent. The microbiological analysis system comprises a container, a microbiological analysis machine comprising at least two stations for treatment of the support, a conveyor comprising a shuttle adapted to receive and to move the support, the container being adapted to be received on the shuttle, as well as means for evacuating the biocidal agent.
1. A method of microbiological decontamination of a machine comprising an enclosure for treating a support to analyze and a conveyor comprising a shuttle for moving said support within said enclosure in order for it to be treated by successive treatment stations of said machine, comprising the steps of:
obtaining a container adapted to be received on said shuttle and to diffuse biocidal agent in said enclosure;
placing said container containing said biocidal agent on said shuttle;
moving said shuttle within said enclosure between said stations such that said biocidal agent contained in said container diffuses into said enclosure to decontaminate said enclosure; and
evacuating said agent from said enclosure.
2. A method according to claim 1 , wherein the step of placing said container on said shuttle is implemented by disposing said container at the intended location on said shuttle to receive a support to analyze.
3. A method according to any one of claim 1 or 2 , comprising, prior to the step of placing said container on said shuttle, the step of selecting, as said container, a support that is identical to those intended to be analyzed.
4. A method according to claim 1 , further comprising the step of selecting, as said conveyor, a conveyor of which the shuttle is adapted to receive a support comprising a membrane and a tubular body surrounding said membrane.
5. A method according to claim 1 , comprising, prior to the step of placing said container on said shuttle, the step of depositing in said container a precursor agent of the biocidal agent and, between the step of placing said container on said shuttle and the step of moving said shuttle within said enclosure between said stations, the step of activating said precursor agent.
6. A method according to claim 5 , wherein said step of activating said precursor agent is implemented by a step of heating said precursor agent.
7. A method according to claim 6 , wherein the heating is heating by microwaves.
8. A method according to any one of claims 5 to 7 , comprising the step of selecting hydrogen peroxide in liquid phase as said precursor agent.
