5 tips to optimize performance and comfort

 

How to Use

Tips for Proper Stethoscope Use

3M™ Littmann® Stethoscopes are known for first-class sound quality and comfort. But there are some simple things you can do to ensure the performance and wearability of your new scope. Check the following:

Headset Alignment

Before placing the eartips in your ears, hold the headset in front of you with the eartubes pointing away (Figure A). Once the eartips are in your ears, they should point forward (Figure B). Not all ear canals are alike. If after inserting the eartips properly the fit still isn’t comfortable, and/or acoustic performance is lacking, grasp each of the eartubes and adjust the headset for a custom fit. Wearing the headset improperly (Figure C) can result in a poor acoustical seal and in some cases, complete sound blockage.

Fit of Eartips

For optimal acoustic performance, it’s important to use the eartip size that best fits your ear. This is especially true when using the soft-sealing eartips. All eartips are available in small and large.

Possible Obstructions

If you usually carry your stethoscope in a pocket or don’t clean it often, lint or dirt may accumulate and obstruct the sound pathway. To prevent debris from accumulating, give your stethoscope routine cleaning and care.

The Seal

Stethoscopes rely on an airtight seal in order to transmit body sounds from the patient to the practitioner’s ears. Loose parts in the chestpiece, loose tubing, or cracked tubing can prevent an airtight seal.

Open the Bell

When using a double-sided stethoscope, you need to open (or index) the bell or diaphragm by rotating the chestpiece. If the diaphragm is open, the bell will be closed, preventing sound from coming in through the bell, and vice versa.

 

Cleaning & Care

How to keep your stethoscope in great shape

Give your stethoscope some love

Your 3M™ Littmann® Stethoscope is designed to provide years of reliable service. Cleaning it routinely ensures optimal acoustic performance, helps extend the life of the scope, and leaves it looking shiny and new.

General Cleaning Tips

If your stethoscope needs to be disinfected, wipe with a 70% isopropyl alcohol solution

Do not immerse your stethoscope in any liquid or subject it to any sterilization process

Keep your stethoscope away from extreme heat, cold, solvents and oils

Eartips can be removed from the eartubes for thorough cleaning

Tubing Care

Most Littmann® Stethoscopes feature tubing made of polyvinyl chloride (PVC). PVC becomes hard when exposed to skin for long periods of time. If you like to wear your stethoscope around your neck, wear it over a collar to keep the tubing flexible.

A 3M™ Littmann® innovation

You’ve earned the right to wear the best. 3M™ Littmann® Stethoscopes are renowned worldwide for unsurpassed quality, performance and innovative design. One of the innovations that makes Littmann stethoscopes unique is our tunable technology.

How Tunable Technology Works

Our tunable, or dual-frequency, stethoscope diaphragms combine the bell (for low frequencies) and the diaphragm (for high frequencies) into a single side of the chestpiece. Move between bell and diaphragm modes by simply varying the pressure applied to the patient—there’s no need to turn the chestpiece over.

Using Bell Mode (for low frequencies)

For low-frequency sounds, rest the chestpiece lightly on the patient. When the diaphragm membrane is suspended, the membrane resonates low-frequency sounds.

Using Diaphragm Mode (for high frequencies)

For high-frequency sounds, use firm contact pressure on the chestpiece. By pressing on the chestpiece, the movement of the diaphragm membrane is restricted. This blocks (or attenuates) low-frequency sounds and allows you to hear higher frequency sounds.
