A stethoscope that is easy to capture characteristic sounds

Abstract

The invention provides a stethoscope capable of easily capturing characteristic sounds. The stethoscope comprises a sound pickup device. The sound pickup device is communicated with a sound transmitting base tube. The sound transmitting base tube is divided into a first tube and a second tube. The first tube and the second tube are communicated with independent earplugs respectively. A metal tube / metal tubes is / are connected to the interior of the first tube or / and the interior of the second tube. Each metal tube is wrapped by a tubular semiconductor refrigerating sheet. One heat exchange face of each semiconductor refrigerating sheet surrounds and is tightly attached to the corresponding metal tube, and the other heat exchange face of each semiconductor refrigerating sheet is outward. The semiconductor refrigerating sheets are provided with a power source. By means of the stethoscope, the difficulty for capturing the pathological characteristic sounds with short duration time can be reduced, and the auscultation efficiency and the auscultation accuracy can be easily improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a stethoscope. Background technique [0002] In the medical diagnosis process, a stethoscope is a commonly used medical device, which is mainly used to auscultate the internal signs of the body, such as heart and lung disease problems. Since the human body is a complex system, when listening to the internal sound of the human body, in addition to the specific frequency sound produced by pathological features, it is also accompanied by a large number of ordinary noises. Moreover, the characteristic sounds caused by some pathologies are not continuous and often appear Therefore, it is more difficult to detect pathological characteristic sounds with a relatively short duration, and it may be difficult for inexperienced auscultators to capture and distinguish them. It can be seen that the pathological discrimination ability of ordinary stethoscopes is currently limited. Contents of t...

Since the human body is a complex system, when listening to the internal sound of the human body, in addition to the specific frequency sound produced by pathological features, it is also accompanied by a large number of ordinary noises. Moreover, the characteristic sounds caused by some pathologies are not continuous and often appear It flashes by. Therefore, it is more difficult to detect the pathological characteristic sounds with a relatively short duration. It may be difficult for inexperienced auscultators to capture and distinguish them. It can be seen that the pathological discrimination ability of ordinary stethoscopes is currently limited.
