Prevention
Check the transducer for cuts, frayed
insulation, kinks, or other
abnormalities.
Cover the patient's teeth with a bite
guard (mandatory). Cover the distal tip
and flexible shaft with a transducer
cover (recommended, but in China and
Japan, mandatory).
Suspend the transducer from a wall-
mounted rack and the distal tip with a
tip protector when not in use.
Never sterilize the transducer by using
bleach, steam, heat, or ethylene oxide
(EtO). Never immerse the steering
mechanism in any disinfectant or liquid.
