摘要

血管方面的疾病為國人的前十大死亡病因之ㄧ，其死亡的年齡分布主要發生於65到84歲之間，但由於生活環境因素與生活作息不正常等等原因導致因高血壓性疾病而死亡的年齡有下降的趨勢。本研究自製一台量測血壓的裝置，其與傳統血壓計不同處，在於壓力感測器和流量感測器皆為數位式感測器，並利用數位濾波器來取代傳統類比濾波器，同時以動態的收縮壓、舒張壓比值來取代傳統理論的收縮壓、舒張壓比值，結果我們將所得到估測的收縮壓、舒張壓與平均血壓，與聽診器所得到實際收縮壓、舒張壓與平均血壓來做比較，其相關度分別為0.84、0.90、0.88。

In Taiwan, people die in Blood vessel disease have higher ratio, the age distribution of death occurs mainly between 65-84 years, but, due to the living environment factors and abnormal rhythms of life, leading to death Age of hypertensive disease have downward trend. In this study , we made a device of measurement of blood pressure, differences with the traditional sphygmomanometer is the pressure sensor and flow meter sensor are all digital sensors, and use the digital filter to replace the traditional analog filter, , then the dynamic ratio of systolic and diastolic to replace the traditional theory of systolic and diastolic ratio, finally, we use estimate the systolic, diastolic and mean blood pressure to comparison with the stethoscope actual systolic, diastolic and mean blood pressure, relevance were 0.84,0.90,0.88.
