I. Maintenance of Sound-Conducting Tubing
1. Cleaning: Gently wipe the surface with a soft cloth dampened with 75% alcohol; do not soak in water or expose to highly corrosive agents for extended periods.
2. Storage: Lay flat or hang up; avoid prolonged folding or wrapping around the neck to prevent the tubing from twisting or cracking.
3. Environmental Precautions: Keep away from heat sources and direct sunlight; avoid contact with oils or degreasers to delay rubber aging and hardening.
II. Maintenance of Chestpiece Diaphragms
1. Usage: Control pressure during auscultation; avoid excessive force that could deform or damage the diaphragm.
2. Cleaning: Gently wipe with a cotton swab dipped in a small amount of alcohol; prevent liquid from seeping inside the diaphragm, which could impair sound transmission.
3. Protection: Avoid placing heavy objects on the chestpiece during storage and protect the diaphragm from scratches caused by sharp objects.
III. Tips for Extending Eartip Lifespan
1. Cleaning: Wipe with a soft cloth and clean water; avoid strong acidic or alkaline cleaners to prevent the silicone or rubber material from hardening.
2. Replacement Cycle: Replace eartips every 6 months to avoid loss of elasticity and reduced sealing performance due to prolonged use.
3. Storage: Keep away from substances that accelerate material aging, such as alcohol or oils, to delay hardening.
IV. General Guidelines for Extending Lifespan
1. Disinfect skin-contacting parts promptly after each use to prevent residual bodily fluids from corroding the components.
2. Conduct a thorough inspection of all vulnerable parts every 1–2 months; address any minor cracks or signs of hardening immediately.
3. When not in use for extended periods, clean the stethoscope, place it in a sealed bag with a desiccant, and store it properly to prevent humidity from accelerating rust and aging.
