Inspection of the mouthpiece (MA-651)
Figure 3.15
Do not use a mouthpiece that is damaged, deformed or reveals other irregularities.
Doing so may cause patient injury and/or equipment damage.
Placing the mouthpiece in the patient’s mouth before the procedure prevents the
patient from biting and/or damaging the endoscope’s insertion section.
1 Confirm that the mouthpiece is free from cracks, deformation or discoloration.
2 Using your fingers, check all surfaces of the mouthpiece for scratches, cracks, or
other irregularities.
