The design of electronic sphygmomanometer with function of hemodynamic parameters detecting

The electronic sphygmomanometer with function of hemodynamic parameters detecting is designed in this paper, it can not only measure systolic and diastolic blood pressure, but also calculate cardiovascular hemodynamic parameters. It adopts the C8051F020 single-chip microcomputer as the core of calculating and processing of the device. The method of oscillometric is used to get the mean arterial pressure, systolic blood pressure and diastolic blood pressure. The electronic sphygmomanometer with the function of hemodynamic parameters detecting can measure the systolic and diastolic blood pressure accurately, and it can also get the result of hemodynamic parameters from people. The systolic and diastolic blood pressure and the hemodynamic parameters can be got in the same time with the instrument which is designed in this paper, the instrument provides more reliable evidence for the diagnosis of disease, and it enriches the functionality of electronic sphygmomanometer, and expands the application scope of the electronic sphygmomanometer.
