在现代医学中,正在广泛应用各种各样的电子测量技术,特别是在诊断方面,为了掌握人体的各种生理参数,了解有关人体各系统的功能,利用电子技术对病人的脉搏、血压、心电、呼吸、体温、心音、血氧等自动测定或连续监测配合过限报警,以获得可靠的资料,便于迅速、准确地掌握病情,及时抢救病人,具有十分重要的医疗价值。医用电子测量仪器基本上是由医用换能器、医用电子放大器和医用电子记录器三个主要部分组成。而医用换能器的作用是把要测定的生理参数转换成工程技术上较易测定的电信
In modern medicine, a wide range of electronic measurement techniques are being widely used, especially in diagnosis. In order to grasp various physiological parameters of the human body, understand the functions of various human systems, use electronic techniques to measure the pulse, blood pressure, ECG, respiration, body temperature, heart sound, blood oxygen and other automatic measurement or continuous monitoring with over-alarm, reliable information to facilitate rapid and accurate grasp of the disease, timely rescue of patients, has a very important medical value. Medical electronic measuring instruments are basically medical transducers, medical electronic amplifiers and medical electronic recorders composed of three main parts. The role of medical transducers is to determine the physiological parameters to be converted into engineering and technology easier to determine the telecommunications
