Fitting the eartip on the probe
1.
Select an eartip that fits the patient's ear canal. You may have to try out a number of sizes in order to select the appropriate size.
2.
Gently push the eartip onto the probe tip until it rests firmly against the base of the probe. It is much easier to attach and remove the
eartip if you turn it gently. When you do so, make sure that you hold the probe by the probe body and
not by the cable
.
Caution: Make sure that you gently push the eartip onto the probe tip until it rests firmly against the base of the probe.
Note: Accurate testing is only guaranteed if you use the eartips provided.
Note: The eartip can be used for both ears. If you suspect infection in one ear, change the eartip and clean the probe tip, or replace it with a
spare, before you continue testing on the other ear.
Caution: Using a probe with an unsuitably sized eartip or applying excessive force may irritate the ear canal.
Note: In case of a probe error, make sure that the probe tip channels are clear (see
) and that the probe is
connected. See also
4.4.2
Inserting the probe with eartip in the patient’s ear canal
When you have fitted an eartip on the probe, grasp the pinna and gently pull back and slightly away. Insert the probe in the ear canal, with a
slight pressure, twisting the probe slightly as you insert it.
Verify visually the correct fitting.
The probe can be inserted with the probe cable pointing either upwards or down, depending on the direction that fits best.
Make sure the probe fits well. Any leakage may increase the test duration due to sound leakage, excessive noise, or both.
Attach the clip to the patient's clothing or bedding to secure the probe cable.
Note: Make sure that the cable is not in contact with any vibrating surfaces during testing.
Caution: In case of ear or ear canal trauma, do not start any measurements.
