Indications for Use
Smart-Read EZTest – Steam self-contained biological indicators (SCBI) are for monitoring the efficacy of pre-vacuum saturated steam sterilization processes. Performance characteristics are established in accordance with USP 31 for the 121°C steam process. Additional pre-vacuum saturated steam sterilization temperatures are also included in the Certificate of Analysis. Smart-Read EZTest – steam SCBIs are also appropriate for use in processes of 132°C, 134°C and 135°C. The Smart-Read EZTest - steam SCBI is placed into a sterilizer load in a horizontal position in a location that is judged to be the most difficult to sterilize. A sterilization cycle appropriate for the particular type of load is run. Following the sterilization cycle, the operator removes the SCBI from the load and waits approximately 10 minutes until the device has cooled so it can be comfortably handled. The operator then activates the self-contained ampoule by placing it into the activation well in the Smart-Well incubator and gently pulling forward. This action mechanically flexes the side wall of the plastic vial to break the glass ampoule containing the culture medium. The activated Smart-Read EZTest – steam SCBI is then placed in an incubator at 60 ± 2°C for 10 hours which provides conditions conducive to growth of any bacterial spores which might have survived the sterilization cycle. Microbial growth of the indicator organisms will produce acid in the microbiological culture medium containing bromcresol purple, thus lowering the pH of the solution and invoking a yellow color change of the media components. If sterilization conditions are met the spores have been killed and the media will remain clear and purple at the conclusion of the 10 hour incubation time.
Device Story
Self-contained biological indicator (SCBI) for steam sterilization monitoring; contains Geobacillus stearothermophilus spores on paper carrier and glass ampoule of bromcresol purple culture medium within polypropylene vial. Device placed in sterilizer load; after cycle, operator cools device, then activates by flexing vial to break internal ampoule. Activated unit incubated at 60°C for 10 hours. If spores survive, microbial growth produces acid, turning medium yellow; if sterilized, medium remains purple. Provides visual confirmation of sterilization efficacy to healthcare personnel.
Clinical Evidence
Bench testing only. Reduced incubation time (10 hours) validated by exposing 100 biological indicators to steam processes reducing spore population to ~1 spore/unit. Performance met USP 31 and ANSI/AAMI/ISO 11138-1 requirements, with 97% of results available at 10 hours compared to 7-day incubation.
Technological Characteristics
Self-contained biological indicator; polypropylene vial (1.75" x 0.34"); Geobacillus stearothermophilus spores (ATCC 7953) on Whatman filter paper; Type I borosilicate glass ampoule with soybean casein digest medium and bromocresol purple; autoclavable filter paper vent. Complies with USP 31 and ANSI/AAMI/ISO 11138-1.
Indications for Use
Indicated for monitoring the efficacy of pre-vacuum saturated steam sterilization processes (121°C, 132°C, 134°C, and 135°C) in healthcare settings.
Regulatory Classification
Identification
Biological sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor adequacy of sterilization. The device consists of a known number of microorganisms, of known resistance to the mode of sterilization, in or on a carrier and enclosed in a protective package. Subsequent growth or failure of the microorganisms to grow under suitable conditions indicates the adequacy of sterilization. Physical/chemical sterilization process indicator: A device intended for use by a health care provider to accompany products being sterilized through a sterilization procedure and to monitor one or more parameters of the sterilization process. The adequacy of the sterilization conditions as measured by these parameters is indicated by a visible change in the device.
