INSTRUCTIONS FOR USE Operating Instructions Start-up

Readout Procedure

Place unit on a firm level surface. Plug unit into an appropriate AC grounded outlet.

Follow this procedure for every RRBI to be read:

Allow a 30 minute warm-up period before placing RRBIs into the incubation wells. The C1 caution code will disappear when proper incubation temperature is reached. It is recommended that the unit be left on to eliminate warm-up periods. The unit may be turned off when it is anticipated that it will not be used for an extended period.

Step 1. While wearing gloves and safety glasses, CLOSE RRBI cap by pressing down.

Step 2. CRUSH the glass ampule (containing growth media) in the designated crushing well built into the incubator.

Step 3. Hold the RRBI by the cap and TAP bottom of the vial on a tabletop until media wets spore strip at bottom of vial. Do not tap vial on unit.

WARNING

Step 4. Open the cover and PLACE the RRBI into an incubation/reader well.

Step 5. CLOSE the cover on the Attest 290 Auto-reader and wait for either the red or green indicator light to signal the result.

Do not remove or change placement of RRBI once it is placed into a well. Doing so may result in loss of results and the RRBI test may be invalid.

Attest 290 Auto-reader

INSTRUCTIONS FOR USE

Wells are color coded to match the cap of each type of biological indicator; i.e. the 1291 RRBI with a blue cap goes into a blue well and the 1292 RRBI with a brown cap goes into a brown well. A yellow light will come on to indicate the RRBI is incubating in the reader well and should not be touched. A yellow light indicates the results are not available and incubation is in progress. Do not remove RRBIs until the red (+) or green (-) light indicates the test is complete. Note: If RRBIs are inadvertently removed before the incubation period is complete, an alarm will sound and all three lights (+, •, and -), for that incubation well will light. C2 Caution code will also be displayed. You must return the RRBI to the reader well within 10 seconds or the results will be lost.

WARNING Do not remove or change placement of RRBI once it is placed into a well. Doing so may result in loss of results and the RRBI test may be invalid.

All red, yellow and green lights will flash for one second when the cover is opened demonstrating they are functional. The cover should only be opened when placing additional RRBIs into incubation wells or when removing RRBIs at the completion of the designated incubation period. A positive result (+) will automatically be shown as soon as it is detected. The full incubation period is required before a negative result (-) is shown. The Attest 1291 RRBI requires 1 hour of incubation and the Attest 1292 RRBI requires 3 hours of incubation before a negative (-) result will be shown. The negative result will be shown automatically after completion of the required incubation time. The processed indicator and the positive control may also be further incubated for a visual pH color change. The final negative reading (media remains purple) for a visual color change is made at 24 hours (1291) or 48 hours (1292). The positive control should show a yellow color change of the growth media. For any incubation beyond 24 hours (1291) or 48 hours (1292), RRBIs should be moved to a humidified environment. Each facility must establish final readout time in its policy and procedures. The policy should be based on manufacturer’s instructions for use, scientific knowledge, current recommendation practices, applicable compliance requirements, inventory levels, and the risk to the patient if the medical device is not sterile.

Attest 290 Auto-reader

INSTRUCTIONS FOR USE Positive Control Crush, tap and incubate at least one non-processed Attest 1291 or 1292 RRBI to use as the positive control each day that a processed RRBI is incubated and read by the unit. Write a “C” (for “control”) and the date on the label. The positive control can be placed in any incubator well of the unit. The positive control should be the same part number, from the same manufacturing date and lot number as the processed RRBI in the unit.

It is good practice to use a positive control each day a sterilized RRBI is processed. This helps ensure: - correct incubation temperatures are met. - viability of spores has not been altered due to improper storage temperature, humidity, or proximity to chemicals - capability of media to promote rapid growth, and - proper functioning of Attest 290 Auto-reader components.

Interpretation of Results Each incubation/reader well has three corresponding indicator lights: a red (+), yellow (•) and green (-) light. After placing a RRBI into a corresponding color-coded well, a yellow light will illuminate to indicate that incubation/reading is in progress.

The final negative processed RRBI reading for a fluorescence change (green light -) after 1 hour (1291) or 3 hours (1292) indicates an acceptable sterilization process. The positive control should read positive (red light +).

A red light (+), will illuminate and an alarm will sound (if the sound feature is turned on), as soon as a positive RRBI result is detected.

If the processed RRBI is further incubated for a visual pH color change, when special studies are desired, the media color change from purple to yellow will also indicate a sterilization failure. The positive control should show a yellow color change at 24 hours (1291) or 48 hours (1292). A final negative color change result (no color change), media remains purple , is made at 24 hours (1291) or 48 hours (1292).

At the end of the specified incubation time, if a negative RRBI result is detected, the green light (-) will illuminate indicating an acceptable sterilization process. After either the green or red light comes on, the RRBI can be removed from the well. The RRBI should not be removed or touched when the yellow light is on. The positive (unprocessed) control RRBI must provide a positive fluorescent result (red light +). Processed RRBI results are not valid until the positive control reads fluorescent positive (red light +). With the processed RRBI, a positive (red light +) result means a sterilization process failure may have occurred.

Act on any positive result immediately. The positive result indicates a sterilization process failure may have occurred. Determine the cause of the positive RRBI following current facility policies and procedures. Always retest the sterilizer and do not use the sterilizer for processing loads until 3 consecutive RRBI results are negative.

Disposal Dispose of the used Attest RRBI according to your healthcare facility policy.

You may wish to sterilize any positive RRBI prior to disposal.

Attest 290 Auto-reader

FEATURES, CARE AND CLEANING Features Audible Alarm An audible alarm will sound and the positive red (+) light will illuminate for the designated incubation/reader well when a positive result is detected. This provides results in the least amount of time without the need to manually take frequent readings. An alarm will also sound if a RRBI is removed from the Attest 290 Auto-reader well before a final result has been detected. Data will be lost if the RRBI is not replaced in the reader/incubation well within 10 seconds. Alarm On/Off The audible alarm for positive results can be turned off or on for a particular RRBI. This is accomplished by pressing the "alarm off" button after the alarm has sounded. This will turn off the alarm for that RRBI only. Any positive RRBI results detected in other wells will result in the alarm sounding. Removing the RRBI will reactivate the alarm for that well. Pressing the “alarm off” button will not silence the alarm for error or caution code alarm warnings.

To turn the alarm function back on, press the "alarm off" and "time remaining" buttons at the same time. The yellow period on the display panel will turn off, indicating that the alarm is again active. Time Remaining When the “time remaining” button is pressed, the incubation time remaining for each individual incubation/reader well that contains a RRBI will be displayed. All three lights for each individual incubation/reader well will illuminate as the time remaining is displayed. The process begins with the incubation/reader well containing a RRBI on the left and proceeds to the right. The time remaining appears in hours until there is less than an hour remaining when it displays minutes remaining. Temperature Monitoring The Attest 290 Auto-reader contains an internal temperature self-diagnostic program. Should the temperature fall outside the specified range (60ºC +/-2ºC) an error code will be displayed. Power Cord Retaining Clip

To turn alarm function off (disable), press both the "alarm off" and "time remaining" buttons at the same time. A yellow period will appear on the lower right corner of the display panel to indicate the alarm is disabled. The alarm will be disabled for all positive RRBIs, error codes, and caution code alarm warnings.

Place the power cord through the power cordretaining clip on the rear of the Attest 290 Autoreader near the plug in. This will help to ensure that the power connection does not become inadvertently disconnected.
