1. Sound-transmitting tubing
This is the component most susceptible to damage. Typically made of PVC, it has poor tensile strength; frequent bending and pulling during daily use can easily lead to cracking or breakage due to material aging, directly impairing sound transmission.
2. Chestpiece diaphragm
Prolonged friction and compression make it prone to damage and aging. This can result in unclear sound transmission and potential air leaks, making it a frequently damaged component.
3. Eartips
Frequent removal and cleaning can cause them to become loose, lose elasticity, or even crack and break, directly affecting wearing comfort and sound reception.
After use, it is recommended to hang the stethoscope flat to minimize unnecessary bending of the tubing; this can effectively extend the lifespan of these vulnerable components.
