Inspection of the biopsy valve
The biopsy valve is a consumable that should be inspected
as follows before each use. Replace it with a new one if any
irregularity is observed during the inspection. An irregular,
abnormal, or damaged valve can reduce the efficacy of the
endoscope’s suction system, and may leak or spray patient
debris or fluids, posing an infection control risk.
1.
Confirm that the slit and hole on the biopsy valve have no splits, cracks,
deformations, discoloration, or other damage (see Figure 3.8).
