The invention concerns a method for sterilizing objects (19), in particular medical or surgical instruments, which consists in subjecting a gas stream circulating in a chamber wherein an industrial vacuum is created to the action of an electric field so as to create a gaseous plasma whereof the post-discharge stream which is derived therefrom is admitted into a sterilizing chamber where it is contacted with the surface of the objects to be treated. Said device is characterized in that the gas stream consists of a mixture of nitrogen, and of an amount of hydrogen less than 5 %. It comprises means for heating said objects capable of bringing the latter, during treatment, to a temperature not less than 60 °C. The invention also concerns a method using said device.
La présente invention concerne un dispositif de stérilisation d'objets (19), notamment d'instruments médicaux ou chirurgicaux, du type dans lequel on soumet un flux gazeux circulant dans une enceinte dans laquelle on crée un vide de niveau industriel à l'action d'un champ électrique de façon à créer un plasma gazeux dont le flux de post-décharge qui en est issu est admis dans une chambre de stérilisation où il est mis en contact avec la surface des objets à traiter. Ce dispositif est caractérisé en ce que le flux gazeux est constitué d'un mélange d'azote, et d'une quantité d'hydrogène inférieure à 5%. II comprend des moyens de chauffage desdits objets aptes à porter ces derniers, en cours de traitement, à une température d'au moins 6O0C. La présente invention concerne également un procédé de mise en oeuvre de ce dispositif .
