Proper storage of your stethoscope is important to increase its lifespan and prevent damage to its functional and aesthetic aspects. There are many ways of storing your stethoscope for extended periods of time or in harsh environments – here are some of them.
Where to store your stethoscope:
• In the box that it came in.
• In a natural position inside a cool and dry cupboard, drawer or locker.
• Do not expose your stethoscope to extreme heat or cold.
• Store your stethoscope away from direct sunlight as continuous exposure will harden its tubing.
• Do not place/keep your stethoscope near solvents and oils.
• Do not place heavy objects on your stethoscope as it could excessively warp or bend.
• Do not store it tightly folded in pockets.
Your stethoscope will be one of your most-used instruments at work, which makes it susceptible to wear and tear after some time. Here are some common indicators that it may be time to repair your 3M™ Littmann® Stethoscope, find replacement parts, or invest in a new stethoscope.
1. Its parts are worn and torn, or weather-beaten from sunlight exposure.
2. Its tubing becomes hard or cracked due to being exposed for long periods of time to skin oils.
3. Loss of functionality due to e.g. immersion in water
4. Damage to the diaphragm(s), eartips, and non-chill bell sleeves.
• To improve the longevity of your stethoscope, wear it with a collar to minimize skin contact.
