48 Routine Maintenance Welch Allyn TM286 Auto Tymp
Cleaning patient contact reusable devices
To help ensure patient safety, prevent cross infection and provide effective service, Welch
Allyn patient contact devices must be properly maintained. Maintenance should include
cleaning before each use.
The earphone cushions and patient hand switch can be wiped with a slightly damp cloth
containing soap and water, isopropyl alcohol, ammonia based cleaners or bleach based
cleaners. Gently wipe the earphone cushions with the slightly damp cloth taking care not
to get moisture in the speaker portion of the earphones.
We recommend eartips be discarded after use. We do not recommend cleaning and re-
using the rubber probe eartips for tympanometry or the foam eartips used with the insert
earphones.
Probe care - Tymp/Reflex Probe
With normal use, cerumen can work its way inside the probe nose cone (probe tip).
During the warm-up period each day and throughout the day, inspect the probe tip to
make sure it is clean and free of cerumen. Refer to the following instructions for cleaning
and maintaining the instrument's probe.
Probe nose cone cleaning
Remove the nose cone portion of the probe:
1. Hold the body of the probe in one hand (e.g., left) near the tip and grasp the nose
cone of the probe in the other hand (e.g., right).
2. Rotate the nose cone portion of the probe counterclockwise until the nose cone is
completely separated from the probe (See
“Probe nose cone removal” below).
3. Place the probe body securely on a table and inspect the nose cone for cerumen. Use
floss cleaning thread to remove any cerumen by inserting the floss cleaning thread
through the back portion of the nose cone and pulling it through the front opening. It
may be necessary to repeat this several times to remove all the cerumen.

Allyn service representative only. Malfunctions resulting from improper
maintenance or repair by anyone other than an authorized Welch Allyn
representative will be the responsibility of the user.
Note The probe nose cone can be sterilized via conventional methods including
autoclaving.
