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.
