簡化測量血壓程序的信號頂端點搜尋方法與線路

Summary: 本發明提供了一種簡化測量血壓程序的信號頂端點搜尋方法與線路，用於測量信號頂端點出現的準確時間。本發明方法與線路包括多具運算放大器、數種電容、電阻、可變電阻、二極管及晶體管。其測量的信號可以是由人體所發放的心電圖信號（Electrocardiogram－ECG）或是光體積變化描記信號（Photoplethysmograph－PPG）。本發明方法與線路能準確測量心電圖信號以及光體積變化描記信號的頂端點出現時間。本發明方法與線路可用於但不限於無損式、連續式及無腕帶氣囊式血壓計，目的在於簡化後期的信號處理，例如信號頂端點搜尋程序。因此可選用一些運算速度比較慢的信號處理器作信號分析。與常用的信號處理器相比，不但價錢比較低和省電，而且由於程序簡化了，開發處理器的時間亦相對减少，大大增加成本效益。
