Policies and Procedures on Infection Control
3. Aspirate enzymatic detergent solution alternating with air several times through the
biopsy/suction channel. Finished by suction of air.
4. Irrigate the water/air channel with water, then air, checking for blockage.
(Flushing the biopsy/suction and air/water channels will expel secretion, preclude
drying of organic and inorganic debris on lumen surfaces, and may also remove
large numbers of micro-organisms).
5. Check for bite marks or other surface irregularities.
6. Detach the endoscope from the light source/video-processor pump
7. Attach protective video cap (water resistant cap).
8. Transfer the endoscope to the reprocessing room.
Leakage Testing
Conduct leakage testing according to manufacturer’s instruction before immerse the
endoscope in a disinfectant. This test will detect any damage to the interior or exterior of
the endoscope as to prevent expensive repairs later.
1. Attach leakage tester and turn on the pump to pressurize the scope.
2. Remove all the detachable parts of the endoscope.
3. Prior to immersion, confirm the bending section has expanded.
4. Immerse entire endoscope in clean water.
5. Perform leakage test. Observe at the insertion tube, distal bending section and the
universal cord, looking for bubbles coming from the interior of the scope
6. Angulate the tip in all directions during test
7. Remove endoscope from water.
8. Detach tester after tip has deflated.
Cleaning
1. Immerse the endoscope and valves in a sink/basin filled with low-foaming enzymatic
detergent solution of proven efficacy, at the appropriate dilution and specific time
according to the manufacturer’s instructions.
2. Wash all debris from the outer surface of endoscope by brushing and wiping the
instrument under the detergent as to prevent from splashing of contaminated fluid.
3. Brush the distal end with a soft toothbrush. Special attention is paid to the air/water
outlet nozzle and the bridge/elevator where fitted.
4. Brush all accessible channels (insertion tube, universal cord and cylinder portions of
the suction channel, and instrument channel port) with a brush-tipped wire designed
for this purpose, to remove all organic (eg. blood, tissue) and other residues. Brush
at least three times through each channels, cleaning the brush between each brush.
Clean in detergent with a soft toothbrush each time it emerges.
5. For endoscopes with elevators, brush the elevator-wire channel.
6. Attach all cleaning adapters to suction, biopsy, air and water channels.
