Wireless Electronic Sphygmomanometer Automatic Upper Arm Style
Electronic blood pressure monitor principle
Electronic sphygmomanometer is the principle of the oscillometric method, its principle is briefly described as follows: first of all, the cuff is tied to the arm, the cuff is automatically inflated, to a certain pressure (generally higher than the systolic pressure of 30 ~ 50mmHg) after stopping the pressure, start deflating, when the air pressure to a certain extent, the blood flow can pass through the blood vessels, and there is a certain oscillatory wave, the oscillatory wave propagates through the air tube to the pressure sensor, the pressure sensor can detect in real time The pressure and fluctuation in the measured cuff. Gradually deflating the air, the oscillation wave becomes larger and larger. As the contact between the cuff and the arm becomes looser, the pressure and fluctuation detected by the pressure sensor becomes smaller and smaller.
