As an alternative, solution can be drawn into the instrument channels by attaching tubing from an aspirator to the
suction nipple, as long as the aspirator is turned on, detergent solution can be suctioned through the scope.
6) Prior to rinsing, attach the previously removed adapters and components, and purge all internal channels with
air (using a syringe) to expel residual detergent solution out from each channel.
7) Using clean water, immerse the entire endoscope as well as all removed components and thoroughly rinse all
items.
8) With all cleaning adapters, including irrigation tube, still attached to the endoscope, flush all previously air
purged channels with 200 mL clean water. All internal channels must be thoroughly rinsed to remove resid-
ual detergent and debris. Then remove the endoscope and its components from the solution.
9) Rinse water remaining within the channels should be purged using air to prevent dilution and/or adulteration
of antimicrobial agents to be used in the subsequent disinfection or sterilization process.
10) Gently dry all external surfaces of the endoscope with a soft gauze or the like. Dry the objective lens with a
cotton tip applicator. Do not put tension on the insertion tube on the endoscope while drying since the outer
cover of the bending section may be excessively stretched.
WARNING:
Avoid introduction of air during the flushing process.
Confirm that no air bubbles exit from the channel openings at the scope distal tip. The presences of the
air bubbles could prevent contact of the deterfent with channel surfaces.
WARNING:
The enzymatic detergent solution should remain in contact with ALL internal channels and external
scope surfaces for the time period recommended by the manufacturer of the detergent.
WARNING:
It is important that ALL internal channels (air, water, instrument, etc.), external scope surtaces and com-
ponents be thoroughly rinsed with clean water to remove residual detergent solution.
NOTE:
70-90% ethyl or isopropyl alcohol for disinfection followed by compressed air, not greater than 165 kPa
(1.69 kg/cm
2
, 24 PSI), may be used to facilitate drying.
WARNING:
Prior to disinfection or sterilization, it is imperative that any solutions previously used in the cleaning
process be thoroughly rinsed and dried. Failure to do so, could result in ineffective or incomplete disin-
fection and sterilization.
CAUTION:
Never subject the endoscope to ultrasonic cleaning methods employing high-frequency ultrasound.
