MAINTENANCE OF TRANSDUCERS
Do not use liquids or sprays to clean the tympanometer.
Do not allow dust to collect on the transducers. Also:
- The cushions of headphones are made of biocompatible material
but are not sterile: before being used on a new patient, these items
must be sanitized by wiping the surfaces with a proprietary
hypoallergenic disinfectant, following the maker's instructions.
This will prevent the spread of infection.
- The earpieces of the probe are made of biocompatible material and
must be used once only, then discarded in compliance with current
waste disposal regulations.
Earpieces are not sterile. Reusing unsterilized earpieces can cause
ear infections.
CLEANING THE PROBE
To guarantee accurate compliance measurements, the three channels
incorporated into the probe must be kept properly clean. In effect, these
three channels carry the compliance measurement system, the stimulus
speaker, and the pressurization system.
As illustrated below, the probe comprises a main body rigidly attached to
the instrument, a tip (to which the earpiece is fitted) and a screw collar,
which keeps the tip of the probe firmly secured to the body.
The procedure for cleaning the probe will now be described.
