Title (EN) SYSTEM FOR MEASURING THE EFFICACY OF A STERILIZATION CYCLE
(FR) SYSTEME DE MESURE DE L'EFFICACITE D'UN CYCLE DE STERILISATION
Abstract:
(EN) A system is used for determining efficacy of a sterilization cycle. A biological sterilization indicator exhibits fluorescence in response to biological activity which is indicative of bacterial growth in the biological sterilization indicator. The biological sterilization indicator is exposed to the sterilization cycle and is placed in a fluorescence reading apparatus. The fluorescence from the biological sterilization indicator is read to obtain a first fluorescence reading. The fluorescence from the biological sterilization indicator is re-read to obtain a second fluorescence reading. The efficacy of the sterilization cycle is determined based on the first and second fluorescence readings.
(FR) L'invention concerne un système de détermination de l'efficacité d'un cycle de stérilisation. Un indicateur de stérilisation biologique expose une fluorescence en réponse à une activité biologique indiquant une croissance bactérienne dans l'indicateur de stérilisation biologique. L'indicateur de stérilisation biologique est exposé au cycle de stérilisation et est placé dans un appareil de lecture de fluorescence. On lit la fluorescence de l'indicateur de stérilisation biologique pour obtenir un premier relevé de fluorescence. On relit la fluorescence de l'indicateur de stérilisation biologique pour obtenir un deuxième relevé de fluorescence. L'efficacité du cycle de stérilisation est déterminée sur la base du premier et du deuxième relevé de fluorescence.
