Title
(EN) BIOLOGICAL STERILIZATION INDICATOR AND METHOD OF USING SAME
(FR) INDICATEUR DE STÉRILISATION BIOLOGIQUE ET SON PROCÉDÉ D'UTILISATION
Abstract
(EN)
A biological sterilization indicator (BI) and a method of using same for assaying the lethality of a sterilization process. The BI can include a housing, which can include a first portion (104), and a second portion (106), which can be movable with respect to the first portion between a first and second position. The BI can further include a frangible container (120) comprising a liquid. The BI can further include a spore reservoir (114) and a projection (158) positioned in the housing. The projection can be configured to fracture the container when the second portion of the housing is moved from the first position to the second position. The method can include maintaining a minimal cross-sectional area of space around the container when the second portion of the housing is in the first position, and fracturing the container in response to moving the second portion between the first and second positions.
(FR)
L'invention porte sur un indicateur de stérilisation biologique (BI) et sur un procédé d'utilisation de celui-ci pour évaluer la létalité d'un processus de stérilisation. L'indicateur de stérilisation biologique (BI) peut comprendre un boîtier, qui peut comprendre une première partie (104) et une seconde partie (106), qui peut être mobile par rapport à la première partie entre des première et seconde positions. L'indicateur de stérilisation biologique (BI) peut en outre comprendre un récipient cassable (120) contenant un liquide. L'indicateur de stérilisation biologique (BI) peut en outre comprendre un réservoir à spores (114) et une protubérance (158) positionnée dans le boîtier. La protubérance peut être conçue pour casser le récipient lorsque la seconde partie du boîtier est déplacée de la première position à la seconde position. Le procédé peut consister à maintenir une zone d'espace transversale minimale autour du récipient lorsque la seconde partie du boîtier est dans la première position, et à casser le récipient suite au déplacement de la seconde partie entre les première et seconde positions.
