Introduction
Welch Allyn's MicroTymp 2 tympanometry
instrument produces an accurate, objective measurement of middle ear status.
It helps detect otitis media, perforated tympanic membrane, patent tympanostomy
tube, ossicular disruption, tympanosclerosis, and cholesteatoma
 |
Product Overview
and Description
Diagnosing chronic otitis media is often a difficult task. Sometimes the
fluid is visible, often it isn't. The delivery of sound and air pressure
to the ear, precisely measured by advanced microelectronic components like
those used in the Welch
Allyn MicroTymp 2, brings otitis media into sharp focus. You can expect
the most efficient and complete data from this portable tympanometric instrument.
This next generation in tympanometry provides a one second analysis of middle
ear function and a five second printout. In addition to speed, the MicroTymp
2 offers increased ease of operation, increased data and a high capacity
battery for extended use on a single charge.
Middle ear infection and other pathologies produce abnormal tympanograms
that are clearly visible on both the MicroTymp 2 LCD screen and printout.
Foreground and background contrast on its supertwist green LCD screen make
it easy to see at any angle. Word-prompts on the unit direct the operator,
facilitating testing. Asterisks alert the operator to gradient/width abnormalities.
The MicroTymp 2 has an auto erase feature, which means you don't have to
waste time erasing memory. Erasure is accomplished automatically as you
store the next test. This technologically advanced instrument is ideal for
the office practice, the clinic, and mass screenings.
The MicroTymp 2 printer provides complete documentation of middle ear function.
Three forms of information can be selected in the following formats: tympanogram,
tympanogram plus data, and tympanogram plus data and interpretation. The
tympanograms print middle ear function measurements side-by-side and left
to right for quick comparisons. Multiple copies can be produced for parent
consultation or referral. As with the screen on the handle, the printout
also uses asterisks to alert the operator of abnormalities.

Use and Procedure
 |
1. |
Press the test button, then insert the probe tip into the ear. It
is important to examine the patient's ear canal for size prior to
selecting a tip. Also, make sure you select a tip large enough to
create a seal at the entrance of the canal. |
| 2. |
For
a young child the pinna should be pulled back and down. For Adults,
the pinna should be pulled up for proper technique.. |
| 3. |
Watch
the MicroTymp 2 LCD screen as it completes a tympanogram in as little
as one second. The quickness is ideal for the uncooperative patient.
|
| 4. |
Return
the MicroTymp 2 handle to the Printer/Charger and push "Print".
A printout quietly appears in five seconds. |
