Attaching the biopsy valve
If the biopsy valve is not properly connected to the instrument
channel port, it can reduce the efficacy of the endoscope’s
suction system and may cause patient debris to leak or spray
from the endoscope.
Attach the biopsy valve to the instrument channel port with its tab near side in the
illustrated direction.
Push the upper part of the biopsy valve down slantingly onto the instrument
channel port until the valve snaps into place (see Figure 3.8).
At low temperatures, the housing may become stiff and
difficult to attach.
