Intended Use

The EZTest Smart-Well incubator is designed for the incubation of EZTest (steam) self-contained biological indicators (K930682 and K9630682). The Smart-Read EZTest steam SCBI is used to monitor gravity and pre-vac steam sterilization processes at 121° C, 132° C, 134° C and 135° C. The SCBIs should be placed in the sterilizer load at locations that represent difficult to sterilize positions. Following exposure remove the SCBI from the load, wait approximately 10 minutes until the SCBI is cool enough to handle. Place the SCBI in the activation cavity in the Smart-Well incubator and gently tilt forward to fracture the glass media ampoule inside the plastic vial. This mixes the culture media with the spores if any have survived the sterilization process. Remove the SCBI from the activation cavity and place it into one of the eleven incubation cavities. The Smart-Well incubator maintains temperature of 60 + 2° C which is conducive to growth of Geobacillus stearothermophilus spores. The incubation results are either that the SCBI remains purple (negative) indicating no spore growth or the SCBI turns yellow (positive) which means spores were present and grew. When bacterial spores germinate and grow, they shift the pH of the culture medium. This shift in pH provides the visual color change from purple to yellow. Each incubation cavity is provided with an electronic sensor that alerts the user and conveniently documents when this color change occurs. The user then verifies the visual color change. The electronic signals can be sent to a printer which conveniently documents the visual observation.

indicator (SCBI). The Smart-Read EZTest biological indicator contains 10° spores of Geobacillus stearothermophilus derived from ATCC 7953 inoculated onto a paper carrier. The culture medium is a modified soybean casein digest broth containing bromcreso! purple and meets growth promotion requirements when inoculated with 100 spores or less (K930683 and K963841). This single temperature incubator uses a heated aluminum block to maintain the desired temperature of 60 + 2℃. The incubator has a specifically designed cavity in which to insert and activate the non-activated Smart-Read EZTest unit. The Smart-Read EZTest unit is inserted into this cavity and pulled forward to crush the glass media ampoule and activate the unit. This activated Smart-Read EZTest is removed from this cavity and placed into one of the eleven test cavities. Ten cavities are intended for use with exposed test units and one cavity is intended for use with a positive control. The unit is held in the test cavity for the desired duration of the incubation.

The incubator has telltale LED status lights in front of each test cavity. When a Smart-Read EZTest SCBI is placed into the test cavity, the LED is activated and illuminates amber. The LCD screen will display the particular cavity's test status. This message includes specific cavity number, test status and number of whole hours incubated.

The heated aluminum block provides the temperature desired to allow any surviving spores in the Smart-Read EZTest SCBI to germinate and grow. If viable spores are present in the Smart-Read EZTest SCBI, they will germinate and grow. When growth occurs the cells metabolize sugars and shift the pH of the culture medium to an acid pH. When the pH of the medium shifts to acid it will turn from its purple color to yellow. The monitoring of the color of the Smart-Read EZTest BI is accomplished by a very narrow band width LED. This light is absorbed by the purple color of the medium. However, when the media color shifts to yellow, light is transmitted through the sample and detected by a photo diode behind the sample. When a yellow color is present the photo diode is energized. These results are the same as those visually detected by the human eye under conventional incubation conditions. When the electronics in the cavity detect a yellow color (growth), the status LED will shift from amber to red. The LCD screen will indicate the cavity number, positive test status and the whole number of hours incubated when the test status changed.

If there are no viable spores in the Smart-Read EZTest BI, the incubation will be completed with no change in color status. The Smart-Read EZTest has been tested in accordance with the FDA CDRH protocol for reduced incubation time and meets a 10 hour incubation claim. Upon expiration of the setected incubation time and no cover change was detected (negative); the status LED in front of the cavity will shift from amber to green (no change in purple color). The LCD screen will indicate the cavity number, negative test status and the whole number of hours incubated which is the user selected incubation time duration.

When the test status LED changes from amber to either red or green, an audible prompt is communicated to the user to remove the Smart-Read EZTest SCBI from the cavity and visually observe its color either purple or yellow. The incubator is not making any

decisions as to the acceptability of the test results; it is simply prompting the user to visually observe the samples and make appropriate decisions. The conditions detected by the incubator are 100% verifiable by the user. The results that the Smart-Well incubator vields can be achieved in any microbiological incubator that provides the same environment for the growth of viable spores required by the Smart-Read EZTest SCBI.

The Smart-Well incubator also has the provision to add a printer to document the testing events. The printer will document the change in status of the incubated Smart-Read EZTest unit. Information captured by the printer includes the incubator cell number, incubation start time and date, time of status change condition (positive or negative). The printer has the capability to print user pre-selected descriptions, as a convenience and if desired by the user, which include descriptions of the exposure conditions to which the Smart-Read EZTest SCBI was exposed. These options include the following:

- a) cycle temperature
- b) cycle type (pre-vac/gravity)
- c) cycle exposure time
- d) BI lot number
- e) sterilizer number
- f) user identification

If none of the above information is selected, the printer will leave blanks or print "?" mark to indicate that no information was selected.

The information that is sent to the printer can also be forwarded to a PC or data acquisition network.

The incubator functions exactly as described above if no printer is attached or no connection is made to a PC or data acquisition network.

Substantial Equivalence: The EZTest Smart-Well incubator is substantially equivalent to the Steris Verify" incubator. The Smart-Well and Verify incubator have the same intended use and similar features which include: incubation of self-contained biological indicators; use of visible light spectra to assist the user in observing the color change to yellow. This is substantially equivalent to the single cavity in the Verify which illuminates a broad spectrum white light to assist the user in observing the color change to yellow. The Smart-Well incubator has a narrow band LED and an electronic sensor in each cavity to indicate a yellow color change. It also has status LEDs for each cavity to indicate 1) test in progress; 2) yellow color observed (positive); and 3) incubation duration timed out with no color change detected (negative). The Smart-Well also has the capability to have a printer to document the timing of status changes in the color of the biological indicator. The printer also provides a convenient means to document each biological indicator tested. SGM has concluded that the function of the Smart-Well incubator is substantially equivalent to the Steris Verify incubator.

# TAB 7 Indications for Use

#### 510(k) Number (if known): K091950

Device Name: Microbiological Indicator

Smart-Well Incubator

Indications for Use:

The Smart-Well incubator is intended for use with the Smart-Read EZTest selfcontained biological indicators (SCBI). The Smart-Read EZTest - steam SCBI is used for monitoring the efficacy of gravity or pre-vac saturated steam sterilization processes. This SCBI contains 105 spores of Geobacillus stearothermophilus derived from ATCC #7953. Performance characteristics were established in accordance with USP 32 and ISO 11138-1 for the 121°C steam process. Additional saturated steam sterilization conditions are also tested and appear on the Certificate of Analysis for Smart-Read EZTest - steam. These include 132°C, 134℃, and 135℃.

The operational principles of the device are as follows. The Smart-Read EZTest steam SCBI is placed into a difficult to sterilize position in the load and a sterilization cycle appropriate for the particular type of load is run. As sterilization conditions are met, the bacterial spores are destroyed by logarithmic thermal death principles. 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 places the SCBI in the activation cavity of the Smart-Well incubator. The SCBI is then gently tilted forward towards the operator to fracture the glass media ampoule inside the plastic sleeve. This allows the culture media to mix with any surviving spores in the SCBI. The activated BI is then placed into one of the ten incubator cavities. The Smart-Well incubator provides a constant pre-set temperature of 60 + 2°C which is conducive to growth of any bacterial spores which may have survived the sterilization process. The unit is also supplied with an NIST traceable thermometer to independently indicate the incubator block temperature. 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 all spores have been killed, the media will remain clear and purple. The media meets the requirements for growth promotion.

When the activated SCBI is placed into one of the incubation cavities the LED in front of the cavity will illuminate amber, which indicates that the incubator electronically recognizes the Smart-Read EZTest SCBI unit for incubation. Each incubation cavity also has an electronic monitoring system that detects if the BJ is either purple or vellow.

7.1

{7}------------------------------------------------

The Smart-Well incubator can also be supplied with a printer which documents each individual EZTest steam SCBI tested. The printer can also display information that is normally entered into a log book. The recommended incubation hold time of 10 hours has been established using the FDA CDRH Reduced Incubation Time protocol. The printer can also be configured to display BI exposure information that includes 1) exposure time and temperature; 2) cycle type; 3) sterilizer number; 4) BI lot number; and 5) user identification. These are optional entries. If no selection is made, the printed report will default to the previously entered information of place a "?" mark or blank indication to selection was made.

The printed record will always indicate real time and date, incubation cavity being a reported, the incubation start time when the SCBI was placed into the incubation (surely) and the time the test status changed. The result options are 1) NEGATIVE (purple) - incubation time completed with no detectable color change in the Smart-Read EZTest unit, 2) POSITIVE (yellow) – time that a yellow color was detected in the Smart-Read EZTest unit, or 3) TESTING - when a printout is requested and event 1) or 2) have not happened. These results are easily verified by the user as performed in all conventional incubators without printers.

The incubated SCBI should be properly disposed of after the results have been properly recorded. The recommended disposal is to "sterilize by steam 121" for not less then 30 minutes" of follow your institution's practice for disposal or biological waste.
