I. Routine Cleaning: Perform after each use.
Alcohol Wipe: Wipe the diaphragm, earpiece, and tubing with a 75% alcohol wipe, keeping them moist for at least 30 seconds. This effectively kills bacteria.
Note the details: Do not rinse with water, and do not use sharp tools to clean the sound outlet. Use a dedicated small brush or cleaning hook.
II. Professional Maintenance: Every 3-6 months.
Deep Maintenance: It is recommended to have a professional inspection done at a fitting center every 3-6 months, such as ultrasonic cleaning or drying.
Inspect Components: Regularly check the tubing, earpiece, and earpiece for damage and ensure proper connections.
III. Special Scenarios: Frequent cleaning in humid environments.
Summer Sweating: Wipe the outer shell frequently with a soft cloth to prevent corrosion.
Winter Condensation: The sound tube of behind-the-ear stethoscopes is prone to water accumulation. Remove it, shake dry, and then reinstall. IV. Storage Environment: Dryness and Ventilation are Key
After use, store in a dry, clean place, avoiding contact with acids, alkalis, or corrosive substances.
It is recommended to hang it flat to prevent the tubing from tangling or coming into contact with other items.
V. Common Misconceptions: Avoid These Pitfalls
Rinsing with Water: Stethoscopes are precision instruments and are easily damaged by water. Only wipe with alcohol.
Not Replacing the Desiccant: Color-changing silica gel desiccants must be replaced once they change color (e.g., from blue to pink). Ordinary desiccants should be replaced every 1-2 months.
Cleaning with Sharp Tools: Do not use toothpicks or hairpins to poke the stethoscope, as this can easily damage the sound outlet. Use a special small brush or cleaning hook.
VI. Summary: Three Steps to Maintenance
Daily Cleaning: Wipe with alcohol, keeping it moist for 30 seconds.
Professional Maintenance: Perform deep cleaning every 3-6 months.
Storage Environment: Dry and ventilated, avoid corrosion.
