Cleaning, Disinfection and Storage
Clean your stethoscope in-between each patient
with either a 70% isopropyl alcohol wipe or using
a disposable wipe with soap and water. It is a best
practice to use a disposable wipe when cleaning the
stethoscope to remove organic material.
A 2% bleach solution may be used to disinfect your
stethoscope. However, stethoscopes that contain
red pigments in the tubing color (Burgundy, Pink,
Plum, Peach, Raspberry, Orange, etc) experience
slight discoloration after exposure to bleach. Due to
the destructive nature of bleach, only use a bleach
solution on a limited basis and/or when necessary.
The tunable diaphragms, nonchill bell sleeve and
eartips may be removed for thorough cleaning
(ensure all parts and surfaces are dry before
reassembly). To remove the eartips from the headset,
pull firmly. To assemble the eartips, push the small
side of the eartip firmly onto the eartube until it
snaps fully into place.
Do not immerse your stethoscope in any liquid.
Do not subject your stethoscope to any
sterilization process.
Avoid storing your stethoscope in extreme heat.
