1. Brand and quality: Electronic stethoscopes of well-known brands and good quality often use better materials and more advanced technologies, and their service life may be relatively long.
2. Frequency of use: Frequent and high-intensity use will accelerate the wear and aging of components, thereby shortening the service life.
3. Use environment: If it is often used in harsh environments, such as high temperature, humidity, dust, etc., it may cause damage to the internal electronic components.
4. Maintenance: Regular cleaning, disinfection, proper storage, and operation and maintenance in accordance with the instructions will help extend the service life.
5. Technology update: With the continuous advancement of technology, the emergence of new functions and better performance may make the original electronic stethoscope relatively backward in function and thus be replaced in advance.
