医用压力换能器是目前医学上用得最多的一种医用换能器,被心血管、呼吸、脑神经、消化道、泌尿、妇产、骨科、五官和齿科等科系广泛应用。它在临床应用中起着犹如五官对人体的作用,敏捷感知外界压力信息,将人体内的这种生理信息(一般是非电物理量),转换成其他工程上可容易测定的量(一般是电量即电信号),然后输入医用仪器中,通过电子电路或电子计算机进行数据处理,从而将人体压力信息正确地显示出来,以此对疾病进行诊断和治疗。大部份医用压力换能器的结构,是由压力弹性元件和位移传感器两部份组成,如图1所示。前者
Medical pressure transducer is the most used medical transducer in medicine at present. It is widely used in cardiovascular, respiratory, cranial nerves, digestive tract, urinary tract, obstetrics and gynecology, orthopedics, facial features and dentistry. It plays a role in the clinical application as if the facial features on the human body, agile perception of external pressure information, the human body of this physiological information (usually non-electrical physical), can be easily converted into other engineering measurements (usually electricity that is Electrical signals), and then enter the medical equipment, through electronic circuits or electronic computers for data processing, so that the body pressure information correctly displayed in order to diagnose and treat the disease. Most of the medical pressure transducer structure is composed of two parts of the pressure elastic element and the displacement sensor, as shown in Figure 1. former
