| Abstract |
Pulse refers to the fluctuation caused by the pressure of blood passing through the arterial wall when the heart contracts. Different physical conditions have different pulse wave signatures. Therefore, the pulse signal signature has a reference value in Chinese and Western medicine. However, most of the existing pulse diagnosis devices are bulky and expensive. Although portable pulse diagnosis devices have been developed, most of them are fixed-point use and are not suitable for remote home use. The main reason is that the pulse diagnosis device presents three pulse points: cun, guan, and chi, these three signals need to be transmitted synchronously through wireless, and the receiving end must also be able to dissociate these three signals simultaneously. In this way, it has medical reference value. For this reason, this paper proposes a pulse diagnosis instrument with long-distance transmission function. The focus of this research is to reduce the size of the three-terminal electronic pulse diagnosis instrument that is developed by the self-developed imitating traditional Chinese medicine pulse method, and replace the large-area hardware by Arduino programming, and use the Labview platform to achieve long-distance transmission. In the development, due to consideration of lightness and portability, a reflective light sensor is used as a pulse sensing component, an amplifier and a filter are used to form a pulse diagnosis sensing circuit, and a common Arduino microcontroller is used as an analog/digital signal. Convert, and finally perform wireless transmission through WIFI. It is implemented on the Labview platform on the human-machine interface presentation; this research can be installed on various assistive devices in the future to make it more practical. |
