Good
things can get even better!
First released in 2001, the AT235h clinical middle ear
analyzer (the “h” indicates the additional
high-frequency probe tones) has a proven track record
for reliability and a solid reputation worldwide. This
year a number of features have been updated which make
it an extremely attractive choice for both clinical
and screening purposes.
With
manual and automatic test modes, programmable test sequences
for tympanometry, acoustic reflex and reflex decay testing,
plus intelligent pump and probe features, it has become
the ideal tool for impedance testing in most situations.
It can even function as an air-conduction-only, pure
tone screening audiometer when needed.
The
AT235h is designed for speed and convenience:
The
intelligent pump system automatically
compensates for slight pressure leaks, completing the
test for as long as the required pressure can be maintained.
It also modifies pump speed according to tympanogram
gradient, ensuring accurate peak compliance readings
even at high speed. And there is a manual mode for those
who prefer it.
The
unique exchangeable probe system
allows a screening (pencil) probe to be replaced with
a clinical probe in seconds. The AT235h will automatically
recognize the change and adjust the calibration values.
The
AT235h has two independent programmable
automatic test sequences. You can program
these in many ways. One example would be where the instrument
was used as a screening device and then later for clinical
work. Protocol A would be for screening; protocol B
for the more extensive clinical tests. The programmable
reflex protocols allow presentation levels to be set
at fixed levels or to increase until threshold is identified.
Stimuli can also be presented in a defined sequence
(e.g. to display reflex growth). Ipsi- and contralateral
reflexes can be tested in any order and with pure tones
or noise. Reflex decay can also be tested ipsi- or contralaterally.
In fact, more than 40 reflexes can be recorded per ear.
And, with the press of a button, you can do reflex testing
manually. Tympanogram and reflex test results are displayed
simultaneously.
For
young children, there is a Moving Train
function to catch their attention while
tests are running.
Two
tests of Eustachian tube function (one
for intact and one for perforated tympanic membranes)
are included, with patient instructions conveniently
given on the display.
The
AT235h has a built-in thermal printer
for immediate printout and now has a standard USB socket
for even easier connection to a PC. It is fully compatible
with the NOAH database and handles data transfer and
storage with ease.
At
2.8kg (6lbs) the AT235h is easily portable. And when
you travel, the AT235h has a hard-walled
lightweight case for the unit and all
its accessories.
It
isn’t difficult to see why the AT235h is so popular!
