3.3 Preparation and inspection of accessories
Clean and disinfect or sterilize the air/water valve, suction valve, biopsy valve
and auxiliary water tube as described in the endoscope’s companion
reprocessing manual, the “REPROCESSING MANUAL” whose cover lists the
model of your endoscope.
Inspection of the air/water and suction valves
Confirm that the top hole of the air/water valve is not blocked
(see Figure 3.8). If the hole is blocked, air is fed continuously
and patient pain, bleeding and/or perforation can result.
1. Confirm that the holes of the valves are not blocked (see Figures 3.8 and
3.9).
2. Confirm that the valves are not deformed or cracked (see Figures 3.8 and
3.9).
3. Check for excessive scratching or tears in the air/water valve’s seals (see
Figure 3.8).
