Title
(EN) PROCESS FOR CONCENTRATING A STERILANT AND STERILIZING ARTICLES THEREWITH
(FR) PROCEDE DE CONCENTRATION D'UN STERILISANT ET STERILISATION D'ARTICLES AVEC LEDIT STERILISANT
Abstract
(EN)
The present invention relates to a process for sterilization of medical instruments by concentrating a sterilant such as hydrogen peroxide inside of a sterilization chamber and sterilizing articles therewith. The sterilant is concentrated by removing more water from the sterilization chamber than peroxide.
(FR)
L'invention porte sur un procédé de stérilisation d'articles médicaux consistant à concentrer un stérilisant tel que de l'eau oxygénée dans une chambre de stérilisation puis à y stériliser les articles avec le concentré. La concentration de l'eau oxygénée s'obtient en retirant de la chambre plus d'eau qu'il n'y entre d'eau oxygénée.
