The biopsy valve is a consumable item that should be
inspected before each use. Replace it with a new one if
irregularities are observed by following 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 valves have no splits, cracks,
deformation, discoloration or other damage (see Figure 3.8).
