Description

Technical Field

[0001] This utility model relates to the field of medical diagnostic tools, and in particular to a medical stethoscope. Background Technology

[0002] A stethoscope is a medical diagnostic tool used to listen to the internal sounds of the human body. It is frequently used to listen to the sounds of the lungs and heart, and also to listen to blood flow in the intestines, arteries, and veins. Since its invention, the stethoscope has been used to listen to the internal sounds of the human body and has served as an important auxiliary means in diagnosing certain diseases or health conditions.

[0003] During auscultation, in order to accurately repeat and record certain auscultation sites, doctors usually use a marker to draw circular marks on the patient's skin along the stethoscope head as auscultation markers. When making these marks, the patient is often sitting, and the doctor has to bend over or kneel, which causes the doctor's body weight to press on the marker, resulting in the pen tip pricking the patient. Furthermore, if there are many patients or a large number of points to examine, it will also consume too much of the doctor's physical strength.

[0004] Therefore, there is an urgent need for a medical stethoscope to solve the above problems. Utility Model Content
