<p>The invention relates to a steam sterilisation or steam disinfecting method and to a device for treating sterile items inside a chamber. A gas medium present in the chamber, such as the air which enters the chamber when the sterile items are introduced into it is essentially eliminated in a preparatory stage. This is followed by a sterilisation stage during which steam is introduced into the chamber, to destroy any germs present. The steam is maintained in the chamber in a specified state for a predetermined period of time before being essentially eliminated from the chamber during a drying stage for drying the sterile items, the drying stage being part of the end phase of the sterilisation process. Once the pressure in the chamber has been adjusted to the ambient pressure, the chamber is opened and the treated sterile items are removed. According to the invention, a non-condensable gas medium, especially air, is introduced into the chamber during the drying stage before the pressure is reduced to the dry pressure level, the chamber not yet being filled with steam. This allows the steam to be essentially displaced from the chamber and enables the high vacuum required for the drying stage to be produced using an uncooled pump.</p> |
