一次,法国医生雷奈克散步时,看见一群孩子在一根大圆木旁玩,当一个孩子用铁钉在圆木的一端轻轻敲击时,几个无意间把耳朵贴在另一端的孩子高兴得跳了起来,因为他们听到了轻轻而有节奏的敲击声。雷奈克想,铁钉敲击圆木一端的声音可以很清晰地传到另一端,那么病人身体里的声响也应该可以通过某种工具传到医生的耳朵中。他经过反复实验,发明了听诊器。
Once, when French doctor Lenaine walked, she saw a group of children playing beside a log, and when a child nailed it with an iron nail at one end of a log, several children accidentally put their ears on the other end Pleased jumped up, because they heard the gentle and rhythmic percussion. Renek thought that the sound of a nail-tailed log at one end of the log could be clearly transmitted to the other end, and the sound of the patient’s body should also be able to reach the doctor’s ear through some sort of tool. After repeated experiments, he invented a stethoscope.
