| Abstract: | The blood pressure value is an important parameter to determine the patient's condition, thus a real time non invasive monitoring module for the continuous blood purification system application is designed in this work. To achieve a non invasive real time measurement of blood pressure in the circulation line, the monitoring module uses the gas pressure sensor as the detection of blood pressure, low power microcontroller MSP430F449 as the processing core and high precision AD7714 as the analog digital converter module. The experimental results show that the real time blood pressure monitoring module can achieve accuracy of 0.12% , the input and output has good linear relationship, and can reflect the accurate changes of blood pressure in real time. |
