  • Publication number: 20230181049
    Abstract: A blood pressure measurement system according to the present invention comprises: a sensor unit for detecting a human arterial pulse wave and a variable pressure arterial pulse wave; and a blood pressure calculation unit which calculates a blood pressure value using the human arterial pulse wave and the variable pressure arterial pulse wave, wherein the sensor unit senses the pulse wave at a part to which a variable pressure is applied in order to detect the variable pressure arterial pulse wave. Since a blood pressure value calculated from the arterial pulse wave detected at one part of a human body and the variable pressure arterial pulse wave detected at another part of the human body to which the variable pressure is applied can be output, blood pressure can be calculated faster than when using existing oscillometric sphygmomanometers which take at least 40 seconds to measure blood pressure, and thus an accurate blood pressure value can be calculated.
