Abstract

Pour limiter les impacts environnementaux, augmenter la sécurité de fonctionnement et diminuer les coûts de fabrication de maintenance et d’exploitation des installations de stérilisation de produits à usages sanitaires, médicaux ou pharmaceutiques utilisant l’oxyde d’éthylène comme agent actif, il est proposé d’ajouter à une enceinte principale (1) rigide et étanche un dispositif de traitement de l’atmosphère intérieure de l’enceinte principale (1) comportant au moins un groupe d’aspiration et de compression (7) et au moins un séparateur membranaire (5) apte à séparer les molécules d’oxygène et les molécules d’azote, le dit dispositif étant configuré de façon à réintroduire les seules molécules d’azote dans l’enceinte principale (1). On prévoit également les moyens (3 et/ou 14) d’introduire de l’oxyde d’éthylène sous forme gazeuse dans l’enceinte principale (1) ainsi que les moyens de chauffage (24) permettant de porter l’atmosphère intérieure de l’enceinte principale (1) à une température d’au moins 45°C. L’invention décrit et revendique également une enceinte secondaire (18) équipée de moyens (17) permettant de faire varier sa température intérieure, cette enceinte secondaire (18) étant utilisée pour séparer le mélange oxyde d’éthylène / eau de l’azote et pour stocker ce mélange sous forme liquide ou solide entre chaque cycle de remplissage et d’utilisation de l’enceinte principale (1). La gestion de l’atmosphère intérieure de l’enceinte principale proposée par l’invention permet notamment de diminuer les contraintes de rigidité de cette enceinte et d’utiliser des traceurs olfactifs.To limit the environmental impacts, increase operating safety and reduce the costs of manufacturing, maintenance and operation of facilities for sterilizing products for sanitary, medical or pharmaceutical use using ethylene oxide as the active agent, it is proposed to add to a rigid and sealed main enclosure (1) a device for treating the interior atmosphere of the main enclosure (1) comprising at least one suction and compression unit (7) and at least one membrane separator (5) capable of separating the oxygen molecules and the nitrogen molecules, the said device being configured so as to reintroduce only the nitrogen molecules into the main enclosure (1). Provision is also made for the means (3 and/or 14) for introducing ethylene oxide in gaseous form into the main enclosure (1) as well as the heating means (24) making it possible to bring the internal atmosphere of the main enclosure (1) at a temperature of at least 45°C. The invention also describes and claims a secondary enclosure (18) equipped with means (17) making it possible to vary its internal temperature, this secondary enclosure (18) being used to separate the ethylene oxide/water mixture from the nitrogen and to store this mixture in liquid or solid form between each cycle of filling and use of the main enclosure (1). The management of the interior atmosphere of the main enclosure proposed by the invention makes it possible in particular to reduce the rigidity constraints of this enclosure and to use olfactory tracers.
