Stethoscope

Abstract

The invention relates to the field of medical apparatus, in particular to a stethoscope. The stethoscope comprises a sound pick-up, a sound transmitting base pipe is connected to the sound pick-up, aU-shaped sound transmitting pipe is connected to the sound transmitting base pipe, sound listening pipes are connected to both ends of the sound transmitting pipe, the sound transmitting pipe comprises a first channel and a second channel, both the first channel and the second channel are provided with a solution column, saline water is put into the solution columns, the outer side of the solutioncolumn on the first channel is sleeved with a freezing pipe, the freezing pipe is rotatably connected to the solution column, the freezing pipe is provided with an inlet hole, a liquid nitrogen box and a driving mechanism making the freezing pipe rotate are arranged at the outer side of the freezing pipe, the liquid nitrogen box is provided with a spray pipe capable of pointing to the inlet hole,and the spray pipe is provided with a valve; the sound pick-up is provided with an operation mechanism controlling the driving mechanism to work and driving the valve to be opened and closed. According to the scheme, the capturing difficulty of pathological feature sound short in lasting time is lowered, and a doctor conveniently operates the stethoscope while the stethoscopy efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the field of medical instruments, 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. [0003] I...

Problems solved by technology

[0004] However, when using the above-mentioned stethoscope, the doctor needs to hold the pickup and also adjust the length of the telescopic tube

Therefore, this stethoscope cannot adjust the length of the telescopic tube at the same time during the auscultation process. To adjust the length of the telescopic tube, the stethoscope needs to be removed from the ear, which may miss short pathological characteristic sounds, thereby prolonging the time of auscultation. Inconvenience to auscultation
