| Abstract |
The main purpose of this paper is to propose a new type of Chinese Medicine pulse-acquisition system, and applied to pulse wave velocity measurement. Unlike the past, most of the pulse diagnosis instrument acquisition unit is the use of pressure transducers or micro-actuators, etc., belong to a rigid mechanical pulse diagnosis instrument. We use conductive polymer as a material made of sensors, because it has a soft, plastic characteristics can be made of non-rigid pulse diagnosis instrument. In addition, considering the stability of the measurement, the system is also combined with a wrist pulse method to retrieve the pulse. In practice, due to cardiovascular disease is often accompanied by abnormal pulse wave velocity, so the pulse wave velocity is analyzed to verify the feasibility of this system. In signal processing, through the NI ELVIS II data acquisition (DAQ) function, the measure to the radial artery pulse signal acquisition to the LabVIEW platform, the pulse signal waveform reconstruction. Finally, the program will measure the actual number of samples and by experts (medical institutions) interviews to compare the results of implementation, analysis and performance evaluation. |
