Background

The stethoscope is the most commonly used diagnostic tool for internal and external gynecologists, is the mark of the physicians, and the modern medicine is the invention of the stethoscope. Its appearance and sound transmission mode are continuously improved, but its basic structure is not changed greatly, and mainly is formed from sound-pick-up portion (chest piece), transmission portion (rubber tube) and sound-listening portion (ear piece). The stethoscope types currently include a single-use stethoscope, a dual-use stethoscope, a three-use stethoscope, a stand-type stethoscope, a multi-use stethoscope, and a newly-appearing electronic stethoscope; the color can be selected from various colors. And are generally divided into various types by different combinations of auditory heads. The flat stethoscope head is commonly used for auscultating high-tone murmurmurs and has the double functions of large and small flat stethoscope head and is used for detecting low-frequency heart sounds, dilating sounds, third sounds and first and second heart sounds, and children's heart sounds can be heard. The bell-shaped stethoscope head is commonly used for auscultating the high noise of the bass bar and can hear the heartbeat of the baby in the abdomen. The watch type stethoscope head is commonly used for auscultating pulse sounds of wrists.

Traditional stethoscope is in the use, because medical personnel exert oneself violently easily to lead to its listening part to break down to traditional stethoscope's rubber tube can't effectively arrange in order, leads to its shortcoming of inconvenient carrying to appear, consequently, in order to solve this type of problem, we have proposed a prevent stretching out and warp and portable's stethoscope.
