Origin of stethoscope.

On the way from home to the hospital, Lannick saw some children playing the game of scratching one end of wood with pins while listening to sounds at the other end. He was greatly inspired. He temporarily found a thin book with a paper cover, rolled it into a cylinder, and placed one end of the cylinder at the patient’s heart. As a result, he was greatly surprised, so the sound he heard was clearer than before. Lannick’s invention can be said to be the initial prototype of stethoscope.

1. Before the advent of the stethoscope, Western medicine auscultated pleural and cardiopulmonary diseases by attaching it directly to the patient’s chest with ears. When this method meets obese patients, it seems powerless, or even nothing. In 1816, a young and obese female patient was admitted to the ward of the famous French doctor Lannick. Lannick suspected that she was suffering from heart disease, but could not confirm it by auscultation with her ears attached to the patient’s chest.

2. One day, on his way from home to the hospital, Lannick saw some children playing with pins and scratching one end of wood while listening to sounds at the other end. He was greatly inspired. He quickly walked to the hospital ward, temporarily found a thin book with a paper cover, rolled it into a cylinder, and placed one end of the cylinder at the patient’s heart and the other end on his ear. As a result, he was greatly surprised, so the sound he heard was clearer than before. Lannick’s invention can be said to be the initial prototype of stethoscope, when he was only 35 years old.

3. Later, after continuing to think and experiment, Lannick designed and manufactured the world’s first wooden stethoscope. This stethoscope has a straight tubular shape with a çİş heart, a length of 30 cm, a cylinder diameter of 3 cm and a lumen diameter of 5 mm. Two sections can be separated in the middle of the cylinder for portability. At that time, Lannick called this kind of receiver “chest detector”, which was derived from the Greek words “chest” and “examination”. However, because the appearance of this kind of straight-tubular receiver is quite like a flute, people once called it “the flute of the healer”. Until now, a wooden stethoscope similar to the original straight tube is still very popular in obstetrics, because it has certain advantages in listening to fetal sounds. From this point of view, its function is still the same.
