| Popis: | 95 The main propose of the thesis is to acquire the continuous pulse vibration at the patient’s radial artery based on low cuff pressure approach. By introducing the pulse vibration to the low pressure translating formula of dynamic blood pressure tracking capability, continuous blood pressure measurement system based on low cuff pressure approach is achieved. The interface of the system is completed by LabVIEW 7.0. The digital output and the analog input signals are operated by utilizing National Instruments Data Acquisition (USB-6009) Multifunction I/O Card. There are two kinds of signals at the output of the pressure sensor. They are the signal of cuff pressure and the signal of pulse vibration. A filtering and amplifying circuit is introduced to separate the two signals into two analog input channels of USB-6009. Hence, blood pressure can be calculated after acquiring the data. According to the experimental results, it proves the feasibility of measuring continuous blood pressure by low pressure approach. Moreover, a continuous blood pressure measurement system based on low cuff pressure approach of dynamic blood pressure tacking capability is achieved. 24-hours portable continuous blood pressure measurement instrument could be developed to provide more information for research and medical uses in the future. |
