摘　　要：目的:通过对电容压力传感器与电子血压计的结构、原理进行分析,修复受损的电容压力传感器,并对修复后的血压计进行校准。方法:利用常见的正常血压计做为标准压力计,使两血压计处于同一压力水平来校准血压计。结果:电容压力传感器修复后经过对血压计的校准达到其使用标准。结论:电容压力传感器在电子血压计中相对为易损元件且参数易改变,本文所采用的修复方法及校准电子血压计的方法易于普及。Objective： By analyzing the structure and principle of capacitive pressure transducer and electronic sphygmomanometer, the study solves the problems of repairing damaged capacitive pressure transducer and calibration of sphygmomanometer after repair. Methods： This study uses two ordinary sphygmomanometers as the standard manometer, and by making them the same pressure level to calibrate the sphygmomanometer. Results： By calibrating the sphygmomanometer, the capacitive pressure transducer reaches the using standard after repair. Conclusion： In the electronic sphygmomanometer, capacitive pressure transducer is a relatively vulnerable device. Its parameter is easy to change. Comparing with the standard capacitive pressure transducer, this method is easy to promote and popularize.
