Before manual cleaning
Prepare the scope and perform the leakage test
Complete preparation and leakage testing before channel brushing or powered flushing.
Scope preparation
- Confirm that bedside pre-cleaning is complete and that the balloon has been removed and discarded.
- Detach the suction valve and biopsy valve for separate reprocessing.
- Confirm that the MAJ-2295 ultrasound connector cap is dry, clean, and securely attached before immersion.
- Prepare the MAJ-222 suction-cleaning adapter; it will be used for the instrument/suction pathway.
Leakage-test sequence
- Fill a clean basin with reprocessing water and connect the MB-155 leakage tester to the MU-1 maintenance unit.
- Turn the MU-1 on, depress the pin in the tester connector cap, and confirm that air is emitted.
- Confirm that both the tester cap and the scope venting connector are completely dry, then connect the tester.
- Completely immerse the endoscope and observe it for approximately 30 seconds while angulating the bending section.
- Confirm that no continuous stream of bubbles emerges from any location. If a leak is found, remove the scope with the tester still attached and follow Olympus repair instructions.
- After a passing test, remove the scope from the water with the tester attached, disconnect the tester from the MU-1, and wait 30 seconds or until the bending section returns to its normal size.
- Detach and thoroughly dry the leakage tester.
Model-specific sequence
Complete manual-cleaning workflow
Manual brushing remains required. ScopeBuddy Plus supports the subsequent aspiration, measured flushing, rinse, and air-purge stages when connected and programmed for the BF-UC190F.

Prepare fresh detergent
Detergent basin • PPE- Prepare fresh medical-grade detergent at the concentration and temperature specified by the detergent manufacturer.
- Use a basin large enough to completely immerse the endoscope without coiling it too tightly.
- Keep the BF-UC190F completely immersed during the manual-cleaning steps unless a step specifically directs removal.
Clean and inspect all exterior surfaces
Lint-free cloths • brushes or sponges- Completely immerse the scope and thoroughly wipe the insertion section.
- Remove the insertion section from the solution and inspect the objective lens, ultrasound transducer, distal end, and all other external surfaces.
- Repeat wiping until no visible debris remains.
- Immerse and thoroughly clean the control section, boots, universal cord, connector section, and MAJ-2295 cap.
- Inspect every cleaned surface and repeat the cleaning action wherever debris remains.
Brush the instrument and suction pathways
BW-411B or BW-15B • opening brush- From the suction cylinder, advance the channel brush with short strokes until it exits the distal end.
- Clean debris from the bristles in the detergent, pull the brush back through the channel, and repeat until no debris appears.
- From the instrument channel port, advance the channel brush with short strokes until it exits the distal end.
- Clean the bristles, pull the brush back, and repeat until no debris appears.
- Brush the suction cylinder with the opening brush inserted halfway; rotate one full revolution, withdraw, clean, and repeat until clean.
- Brush the instrument channel port with the opening brush fully inserted until the handle reaches the opening; rotate one full revolution, withdraw, clean, and repeat until clean.
Brush the balloon channel and grooves
BW-400B or BW-7B • opening brush- Insert the balloon-channel brush into the irrigation port and advance it with short strokes until it exits the distal end.
- Clean the bristles in detergent, carefully pull the brush back through the channel, and repeat until no debris appears.
- Brush the irrigation-port opening with both the short and long ends of the channel-opening brush, rotating each one full revolution.
- Repeat the irrigation-port brushing until no debris appears.
- Brush both balloon grooves at the distal end until all visible debris is removed.
Connect ScopeBuddy Plus for this EBUS scope
SB-110-HU1016 • MAJ-222- Confirm that the ScopeBuddy Plus daily setup, dosing verification, pump tubing, and facility-approved BF-UC190F program are ready.
- Attach the MAJ-222 suction-cleaning adapter to the scope.
- Use the SB-110-HU1016 universal hookup tubing—not the SB-110-HU1007 GI tubing set.
- Connect the universal hookup tubing to the ScopeBuddy Plus pump tube and to the BF-UC190F exactly as shown on the Olympus EBUS page of STERIS Connection Guide M11952EN.
- Seat the two MAJ-222 legs on the suction port and biopsy/instrument port.
- Connect Connector 3 to the MAJ-222 inlet and leave its pinch clip open.
- Connect Connector 4 directly to the balloon-port Luer fitting.
- Leave the red suction connector and Connector 2 disconnected from the scope, and close both of their pinch clips.
- Confirm that the MAJ-2295 cap remains secure and that all tubing is fully seated, unkinked, and routed without tension.
Aspirate detergent through the instrument/suction path
ScopeBuddy Plus aspiration • MAJ-222- Remove the scope from the detergent only as needed to make the verified hookup, then immerse the distal end in detergent.
- Use the ScopeBuddy Plus aspiration function through the MAJ-222 pathway for approximately 30 seconds or more.
- Confirm that detergent is moving through the intended instrument/suction pathway.
- Do not substitute the conventional Olympus EUS two-stage-valve aspiration wall chart; the BF-UC190F uses the EBUS hookup in the STERIS connection guide.
Fill both channel pathways with detergent
Powered detergent flush- Completely immerse the endoscope and MAJ-222 in detergent solution.
- Run the facility-validated ScopeBuddy Plus fill/flush step that delivers the Olympus-required equivalent of 30 mL once through the instrument/suction pathway.
- Run the verified balloon-channel connection to deliver 30 mL once through the balloon channel.
- Observe the distal openings and confirm unobstructed detergent flow.
- Do not disconnect an immersed pathway until the programmed step is complete.
Wipe and soak
Detergent contact time- While the scope remains immersed, wipe all exterior surfaces again.
- Soak the scope and immersed reusable cleaning adapter for the detergent manufacturer’s required time and temperature.
- The powered flushing aid does not replace the detergent contact time.
Rinse the exterior
Fresh rinse water- Transfer the scope and cleaning equipment to a basin of clean reprocessing water.
- Completely immerse the items and gently agitate them to rinse all external surfaces.
- Move the ScopeBuddy Plus fluid intake to the clean rinse water according to its operator manual and the validated facility procedure.
Aspirate rinse water and air
Instrument/suction pathway- With the MAJ-222 and verified EBUS hookup attached, aspirate clean water through the instrument/suction pathway for 30 seconds or more.
- Remove the scope from the rinse water while keeping the approved hookup attached.
- Aspirate air through the instrument/suction pathway for 20 seconds.
- Confirm that residual water is expelled from the distal opening.
Flush and air-purge the balloon channel
Balloon-port Luer • measured delivery- Using the verified balloon-port connection, flush 30 mL of clean water through the balloon channel five times for a total of 150 mL.
- Remove the scope from the water and use the ScopeBuddy Plus air-purge function to deliver 30 mL of air five times for a total of 150 mL.
- Confirm that water is expelled from the balloon-channel outlet and that the programmed measured delivery is complete.
Disconnect, dry, and inspect
Clean lint-free cloths- Disconnect the universal hookup tubing and MAJ-222 according to their current instructions.
- Thoroughly wipe and dry every external surface of the BF-UC190F and reusable cleaning adapter.
- Inspect the objective lens, ultrasound transducer, distal end, ports, channel openings, balloon grooves, and all exterior surfaces.
- If any debris remains, repeat the complete manual-cleaning procedure.
- Continue with the next required reprocessing stage and process reusable accessories separately.
- Retain or replace the ScopeBuddy Plus 24-hour tubing according to the current STERIS instructions and facility policy.
