2-3. PREPARATION JUST BEFORE INSERTION OF ENDOSCOPE
1) If the endoscope has just recently been reprocessed, has been prepared or stored properly and passed all pre-procedure
inspections, the instrument should be ready to use. If necessary, the scope’s insertion tube may be wiped down with a gauze
dampened with 70-90% ethyl or isopropyl alcohol.
2) Gently clean the objective lens with a cotton-tip applicator moistened with 70-90% ethyl or isopropyl alcohol. A lens cleaner
(anti-fogging agent) may also be applied via gauze or other applicator.
3) Check the endoscopic image and confirm that it is of acceptable quality for clinical use. Refer also to the owner’s manual
supplied with the PENTAX video processor for inspection of the image quality.
4) Prior to trans-oral insertion of the endoscope, place a bite-block (mouthpiece) into the patient’s mouth to protect the endoscope
from damage during the procedure. Failure to do so can result in scratches, tears and/or crushing of the insertion portion of the
endoscope.
5) Apply a medical grade water soluble lubricant to the insertion tube. Do not use petroleum based lubricants.
