3M ™ Littmann ® Classic III ™ Stethoscope User Manual

Intended Use:

The 3M™ Littmann ® Classic III™ Stethoscope is intended for use by healthcare professionals for medical diagnostic purposes
only. It can be used for auscultation of heart, lung, and other body sounds.
Please report a serious incident occurring in relation to the device to 3M and the local competent authority (EU) or local regulatory authority.
Instructions for Use (see Figures pp. 1):
• Place the Stethoscope in Your Ears: The eartips should point forward toward your nose (Figure 1).
• Adjust the Headset Tension for Comfort and Sound Quality: Pull the eartubes apart (Figure 2) or squeeze them together (Figure 3).
• Select the Active Side of the Chestpiece: A mark on the stem identifies which side of the chestpiece is acoustically active. Rotate the
chestpiece to change which side is active.
Use the large side of the chestpiece for adults. Use the small side for pediatric or thin patients, around bandages, and for carotid assessment.
o
• Listen to Low and High Frequency Sounds with Littmann Tunable Diaphragms:
To emphasize lower frequency sounds, use light pressure against the patient (Figure 4).
o
To emphasize higher frequency sounds, use firm pressure against the patient (Figure 5).
o
• Convert to a Traditional Open Bell:
To remove the diaphragm from the small side, hold the large side of the chestpiece in one hand. While wearing an exam glove on your other hand,
use your gloved thumb to peel the pediatric diaphragm off the small side of the chestpiece (Figure 6). Install the non-chill sleeve on the open bell
(Figure 7).
Cleaning, Disinfection and Storage
Clean between exams using a 70% isopropyl alcohol wipe or disposable wipe with soap and water. A 2% bleach solution may be used to disinfect
your stethoscope; however, the tubing may become discolored after exposure to bleach.
The diaphragms, non-chill bell sleeve, and eartips may be removed for cleaning (Figure 6, 7 and 8). Ensure all parts and surfaces are dry before
reassembly. To attach the eartips, push the small side firmly onto the eartube until it snaps fully into place (Figure 9). To prevent ear canal injury,
be sure eartips are firmly attached to the headset before inserting them into your ears.
To prevent stethoscope damage, do not: immerse your stethoscope in any liquid, subject your stethoscope to any sterilization process, or store in
extreme heat. To prevent staining of stethoscope tubing, avoid contact with pens, markers, newsprint, or other printed material. It is good practice
to wear your stethoscope over a collar whenever possible.
Disposal: Dispose of contents/container in accordance with the local/regional/national/international regulations.
