Insert phone
Caution
•
Never insert the contralateral phone into the patient's ear without first inspecting the patient's ear
canal.
Warning
•
The eartip can be used for both ears. If you suspect infection in one ear, use a clean eartip and probe
tip before you continue testing on the other ear.
Warning
•
Do not use the contralateral insert phone in an ear with discharge. Use a supra-aural phone instead.
Warning
•
To prevent cross-infection, use new eartips when you test the next client.
1. Fit a suitably sized foam eartip on the contralateral
insert phone.
2. Before inserting the eartip in the patient's ear, com-
press the foam eartip to make it smaller. Insert the
eartip in the patient's ear until the outer surface of
the eartip is flush with the ear canal entrance.
The eartip will expand in the ear canal within a few
seconds.
Supra-aural phone
1. Fit the supra-aural phone on the patient's head so
that the center of the phone is directed towards the
entrance of the ear canal.
Caution
•
Some ear canals may collapse and pre-
vent the stimulus from entering the ear. In such
cases either use the insert phone or follow local
recommendations.
