CA 2522057

The invention relates to a sterilization testing device comprised of a housing with a test chamber, an indicator placed therein, and with a supply for supplying the sterilization medium. According to the invention, the sterilization testing device consists of at least two housing parts (3) and (5) that are matched to one another. A supply channel (4) is made inside the housing part (3) and serves to supply the sterilization medium. The supply channel (4) is configured in such a manner that it forms the base body of the test chamber (1). The test chamber (1) accommodates the indicator (2) that indicates the completion of the sterilization process. Alternatively to this solution, the invention provides a variant, which is very effective with regard to manufacturing and which permits a quantitative statement regarding the sterilization. Webs are formed inside the housing in the at least partially meandering and/or spiral configuration of the supply channel. These webs, together with, at least in part, the lateral part(s) of the housing parts (3) and/or (5), form a portion of the supply channel (4). A supply channel (4) formed in this manner accommodates the indicator (2).

L'invention concerne un dispositif d'essai de stérilisation comprenant un boîtier comportant une chambre d'essai, un indicateur introduit dedans et une conduite d'amenée pour le milieu de stérilisation. Selon l'invention, le dispositif d'essai de stérilisation comporte au moins deux parties de boîtier (3) et (5) adaptées l'une à l'autre. Une tranchée de conduite d'amenée (4) est incorporée dans la partie de boîtier (3) servant à acheminer le milieu de stérilisation. A cet effet, la tranchée de conduite d'amenée (4) est disposée de manière à former le corps de base de la chambre d'essai (1). Ladite chambre d'essai (1) loge l'indicateur (2) qui affiche la fin du processus de stérilisation. En solution de rechange, il est prévu selon l'invention une autre variante, très efficace en matière de technique de fabrication, qui permet d'effectuer une estimation quantitative quant à la stérilisation. Il se forme dans la configuration au moins en partie sous forme de méandres et/ou de spirales de la tranchée de conduite d'alimentation, des entretoises, à l'intérieur du boîtier, qui constituent, au moins en partie, conjointement avec la/les partie(s) latérale(s) des parties du boîtier (39 et/ou (5), une partie de la tranchée de conduite d'alimentation (4). Une tranchée de conduite d'alimentation (4) ainsi formée loge l'indicateur (2).
