Description
技术领域 technical field
本实用新型涉及医用诊断仪器，具体涉及一种无线网络化数字听诊装置。 The utility model relates to a medical diagnostic instrument, in particular to a wireless networked digital auscultation device.
背景技术 Background technique
听诊器是一种医学仪器，用来聆听人体或动物体内的声音。目前医院医生实际使用的听诊器属于非数字设备，其原理就是物质间振动传导，通过听诊器中的铝膜和空气导管将人体静脉、动脉、心(20-600Hz)、肺(100-1500Hz)、肠(20-1500Hz)内部的声音信号传送到医生的耳膜，医生要根据自己的经验来判断是否异常并计算心率。但这种方式传导的声音经过人耳，只能听到人耳能听到的范围，而不能将人体静脉、动脉、心、肺、肠内部的20-2000Hz范围的信号全部真实地表现出来。现有的各种电子式无线网络化数字听诊装置仅仅是使用拾音器将这些信号拾取、放大、数字化处理显示，同时将模拟放大的信号在本地回放给医生听，无法实现医生对病人远方听诊。 A stethoscope is a medical instrument used to listen to sounds inside the human or animal body. At present, the stethoscope actually used by hospital doctors is a non-digital device. Its principle is the vibration conduction between substances, and the human veins, arteries, heart (20-600Hz), lung (100-1500Hz), intestine (20-1500Hz) The internal sound signal is transmitted to the doctor's eardrum, and the doctor should judge whether it is abnormal and calculate the heart rate based on his own experience. However, the sound transmitted in this way passes through the human ear, and can only hear the range that the human ear can hear, but cannot truly express all the signals in the range of 20-2000 Hz in the veins, arteries, heart, lungs, and intestines of the human body. Various existing electronic wireless networked digital auscultation devices only use pickups to pick up, amplify, and digitally process and display these signals, and at the same time replay the analog amplified signals locally to the doctor, which cannot realize the remote auscultation of the patient by the doctor.
