Design of electronic sphygmomanometer based on pulse wave

Blood pressure is an important data about our health. Accurately measuring blood pressure and controlling blood pressure within the normal range is of great significance to our health. Know whether your blood pressure is in the normal range at any time to reduce the incidence of blood pressure diseases. According to the pulse wave theory and oscillographic method, a blood pressure measurement system is designed by amplifying small signals and detecting and processing technology. The basic principle is: the blood pressure sensor detects the pressure value in the air bag, and the air pressure in the air bag decreases slowly. At this time, the air pressure sensor converts the collected human pulse wave signal into a voltage signal, which is amplified and filtered, and then transmitted to the system for data processing. Finally, the blood pressure is displayed and the measurement is completed.
