More Information
Summary: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.
