Title (EN) VAPOR STERILIZATION USING INORGANIC HYDROGEN PEROXIDE COMPLEXES
(FR) STERILISATION PAR VAPEUR A L'AIDE DE COMPLEXES DE PEROXYDE D'HYDROGENE NON ORGANIQUES
Abstract:
(EN) An apparatus and process for hydrogen peroxide vapor sterilization of medical instruments and similar devices make use of hydrogen peroxide vapor released from an inorganic hydrogen peroxide complex. The peroxide vapor can be released at room temperature and atmospheric pressure; however, the pressure used can be less than 50 torr and the temperature greater than 86 °C to facilitate the release of hydrogen peroxide vapor. Preferred hydrogen peroxide complexes for use in the invention include Na4P2O7.3H2O2 and KH2PO4.H2O2. The heating rate can be greater than 5 °C. Optionally, a plasma can be used in conjunction with the vapor.
(FR) Cette invention concerne un appareil et un procédé permettant d'effectuer une stérilisation par vapeur de peroxyde d'hydrogène d'instruments médicaux et d'autres dispositifs similaires, lequel processus fait appel à de la vapeur de peroxyde d'hydrogène libérée par un composé de peroxyde d'hydrogène non organique. Cette vapeur de peroxyde peut être libérée à la température et la pression atmosphérique ambiantes. La pression utilisée peut toutefois être inférieure à 50 torr et la température supérieure à 86° C, ceci de manière à faciliter la production de la vapeur de peroxyde d'hydrogène. Les complexes de peroxyde d'hydrogène préférés et utilisés dans cette invention comprennent du Na4P2O7.3H2O2 et du KH2PO4.H2O2, la vitesse de chauffage pouvant être supérieure à 5° C. Un plasma peut éventuellement être utilisé en même temps que la vapeur.
