Related background:

As a teenager, Lei Naike liked mechanical engineering very much. However, influenced by his uncle, Lei Naike finally chose unknown medicine as his future career. With the help of his uncle, 14 years old entered the Affiliated Hospital of Nantes University and began to study medicine.

After becoming a doctor, when Lei Naike was walking in the Louvre Square, he saw several children playing games. A child put his ear to one end of a long piece of wood, and he could hear the code scraped out by another child with a pin at the other end. Lei Naike immediately drew a horse-drawn caravan and went straight to the neck hospital. The diagnosis problem that troubled him for a long time was solved, so the stethoscope was born.

After Lei Naike personally made the first stethoscope, some people called it "soloist", others called it "medical trumpet", and his uncle suggested naming it "chest apparatus". After careful consideration, Lei Naike finally decided to name it "Stethoscope".
