摘要： The invention concerns a method for sterilisation by plasma of at least a object which consists in: placing the object(s) to be treated (50) in a treating chamber (10) substantially subjected to atmospheric pressure; introducing in said treating chamber one or several non-biocidal gas mixtures whereof at least one contains moisture; generating a plasma producing species from one of the gas mixtures by generating at least with a high voltage power supply (38) an electric discharge between a high voltage electrode (36) and a ground electrode (40), said electrodes being placed in said treating chamber; driving the plasma species outside the inter-electrode zone (30), towards the surface of the object(s) to be treated (50); and discharging the gas residues derived from the treatment outside the treating chamber. Moisture is directly introduced at the object to be treated or into the inter-electrode zone. The gas mixture contains at least 10 % of oxygen and 10 % of nitrogen and it preferably consists of ambient air. A relative moisture content ranging between 50 % and 100 % is present at the object to be treated. The invention also concerns various devices for implementing said method in particular for sterilising all types of medical objects.

摘要： The invention concerns a plasma sterilisation system in the presence of humidity from a non-biocidal gas containing oxygen and nitrogen of at least an object placed outside the discharge in a sealed treatment chamber substantially subjected to atmospheric pressure, said method comprising the following steps: introducing the humidified non-biocidal gas into the treatment chamber, generating a first plasma discharge A for a specific duration ensuring the efficacy of the sterilising species generated during the following phase in the entire chamber; generating a second plasma discharge B for a specific duration ensuring sterilisation of said object and rinsing the treatment chamber for a specific duration to ensure a non-polluting atmosphere when the chamber is subsequently opened. Preferably, the first plasma discharge and the introduction of humidity are simultaneous and the first and second plasma discharges can overlap such that the generation of the second plasma starts before the end of the first plasma discharge. The invention also concerns various devices for implementing said method in particular for sterilising all types of medical objects.
