A multifunctional stethoscope

technical field

The invention relates to the technical field of medical equipment, in particular to a multifunctional stethoscope.

Background technique

The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists and children, and is a symbol of doctors. Modern medicine began with the invention of the stethoscope. Since the stethoscope was used clinically on March 8, 1817, its shape and sound transmission method have been continuously improved, but its basic structure has not changed much. It mainly consists of the sound pickup part (chest piece), the conduction part (rubber tube) and the listening part (Earpieces) composition, stethoscope types currently include single-purpose stethoscope, dual-purpose stethoscope, three-purpose stethoscope, vertical stethoscope, multi-purpose stethoscope; colors are also available in a variety of colors. It is generally divided into various types by different combinations of listening heads. The flat stethoscope head is often used to auscultate high-pitched murmurs. The double-function flat stethoscope is used to detect low-frequency heart sounds, expansion sounds, third sounds, and first and second heart sounds. Children's heart sounds can already be heard. The bell-shaped auscultation head is often used to auscultate the high murmur of the bass bar, and can hear the heartbeat of the baby in the womb. The dial-type auscultation head is often used to auscultate the pulse sound of the wrist.

Existing stethoscope has following drawback:

1) When it is necessary to check the patient's heart rate, the patient can only count the number of seconds silently in his heart while counting the patient's heartbeat. The operation is relatively difficult and error-prone;

2) The auscultation head is generally made of metal, and the patient will feel a little uncomfortable when touching the patient's skin for auscultation, especially in winter, it will make the patient feel very uncomfortable;

3) Electronic stethoscopes on the market are difficult to sterilize due to complex structure and poor water resistance.
