Cleaning Procedure for Battery Handles, Otoscope and
Ophthalmoscope Heads
Prepare a 70% isopropyl alcohol solution and soak a lint-free sterile cloth. Wipe down
the exterior of the battery handle, otoscope head, and ophthalmoscope head. Care
should be taken to prevent excess liquid from seeping into the devices.
Isopropyl alcohol may be substituted with commonly used hospital disinfectant wipes
for cleaning purposes if desired. Please refer to the directions provided by the manu-
facturer of the wipes for appropriate contact time to ensure effective cleaning and low-
level disinfection.
Care must be taken during cleaning to avoid contacting the magnifying lenses on the
otoscope or ophthalmoscope head with any cleaning solution. Solution residue may
decrease device performance. The lenses of the instrument heads may be cleaned with
a lint-free cloth or lens paper.
Cleaning Procedure for Bent Arm Illuminator, Otoscope Accessories
(Including: Welch Allyn Specula Adapter, Reusable Specula, Nasal Specula), and Bent
Arm Illuminator Accessories (Including Laryngeal Mirrors, Tongue blade, and Tongue
blade holder).
Prepare Enzol
®
, or equivalent enzymatic cleaning solution as per manufacturer’s in-
structions and soak for ten minutes. (Enzol
®
is typically prepared at one ounce of
product per gallon of water or two ounces of product per gallon of water for cleaning
devices with dried-on matter. Enzol
®
will not be effective unless the soaking process is
a minimum of one minute long, although ten minutes is recommended. For devices
with dried on matter, manual cleaning may be necessary to fully remove all contami-
nants and material.) Cleaning solution may be substituted for a 70% isopropyl alcohol
solution. Rinse accessories with lukewarm running tap water for one minute to remove
any residual solution after cleaning. Dry with a clean, lint free cloth. Note: Always
allow components to completely dry before disinfection or use. Do not reuse acces-
sories between patients without proceeding with high level disinfection instructions
outlined in this manual.
Note: When cleaning the Bent Arm Illuminator, the lamp should not be removed dur-
ing the cleaning process.
