1. Remove debris
If the stethoscope is kept in the pocket or is not maintained regularly, the lint, fiber or dust of the clothing may block the ear tube of the stethoscope. Regular maintenance and cleaning can avoid the occurrence of the above situations.
2. Check airtightness
The high-quality sound transmission effect of the stethoscope is related to the closeness between the stethoscope and the patient's body surface, and between the stethoscope and the ear canal of the listener. Loose ear parts, loose Y tube, and damage to Y tube will affect the tightness. The better the fit, the more accurately the sound from the patient's body can be transferred to the listener's ears. So check the status of the stethoscope frequently.
3. Double-sided stethoscope
When using a stethoscope with dual ear heads, the user needs to switch the clock face or membrane face mode of the ear head to use. When using the membrane face, the clock face will be closed to avoid interference. vice versa.
