2, portable blood pressure monitor for home use is mainly composed of MCU, display panel, air pressure sensor, cuff, air pump, battery, etc., and its principle of operation is based on the air cuff in the process of decompression of the fluctuating changes in blood pressure in the arterial vasculature, calculated systolic pressure, diastolic blood pressure, average arterial pressure.
3. Monitor the fluctuating changes of blood pressure in the arterial vasculature through the self-compensated temperature-compensated SIC160 pressure sensor, convert it to frequency, processed by the filtering algorithm, calculate systolic, diastolic, and average arterial pressures, and drive the LCD panel to display the value of the blood pressure and the number of pulses, and broadcast the measurement results by automatic voice.
