Cleaning and Maintenance
General Care
The Kuduwave is a highly sensitive, state of the art device that must be treated with care. It must be
cleaned and disinfected regularly and care should be taken not to damage any of the sensitive
microphones or speakers when cleaning or handling the device.
Cleaning Procedure
The Kuduwave must be thoroughly cleaned and disinfected after each and every use (i.e. before each
new patient is tested) with a cleaning and disinfection wipes complying with EN1276 that are intended
for use on plastic items.
When Cleaning the Kuduwave:
1.
Disconnect all USB cables and use an antibacterial wipe to clean the Kuduwave headset, ear
cups, sound tubes, response button and the bone vibrator (if it was used).
2.
It is important to ensure that during cleaning no liquid enters any holes in the ear cups.
3.
Used foam eartips must be disposed of after each test as medical waste.
4.
When cleaning the device, avoid bending or twisting any of the cables or sound tubes.
5.
If any permanent sharp bends, cracks or holes in the sound tubes are visible, replace them
with spares provided. Calibration can be verified using the standard daily biological
calibration check routine.
6.
Check that the sound tube or stainless steel ear-tip coupler has not become blocked or
obstructed over time.
Warning:
Never use acetone based cleaning products when cleaning the Kuduwave.
Note:
Ear wax and debris can collect in the ear probe. Make sure that there is no debris on the ear
probe or inside the disposable ear tip before placing an ear tip. Once debris or any foreign material has
lodged into the little holes of the ear probe, it may be possible to remove the debris from the holes. If
debris enters the holes, then the debris must be removed, cleaned and disinfected and the calibration
should be verified using the standard biological calibration verification routines.
Warning:
Make sure that there is no debris on the ear probe or inside the disposable ear tip
before placing an ear tip onto the ear probe.
Note:
The recommended daily biological calibration routine is as follows: Put the Kuduwave on your
head and do an automatic Kuduwave pure tone threshold test of all the octave frequencies. Save the
test results. Remove the Kuduwave, turn it around so that the left side is on the right ear and the right
side is on the left ear and redo the automatic Kuduwave pure tone threshold test. Compare the left and
right thresholds of the two tests with each other. None of the thresholds of the compared sides may
differ with more than 10 dB.
Note:
Disposable ear tips of different sizes act as a barrier between the ear probe and the patient.
Never reuse disposable ear tips because old ear wax and cleaning solutions can damage the ear probe
permanently. Cleaning solutions also damage the foam of the eartips and can lead to incorrect readings.
