摘要：
This invention provides an apparatus and method for noninvasive and cuffless blood pressure measurement, which comprises a photoplethysmography amplitude operation unit, a time difference operation unit, a speed operation unit, and an operation unit. The method includes the following steps: calculating the amplitude differences between the characteristic points of photoplethysmography waveform calculating the time point differences between the peak of electrocardiography waveform and the characteristic points of photoplethysmography waveform and calculating the time differences between the characteristic points of photoplethysmography waveform performing operation based on the hand length and the time difference values of electrocardiography and photoplethysmography to obtain the pulse wave transmission speed and, performing operation based on one of the pulse wave transmission speed, the amplitude differences of characteristic points, and the time differences of characteristic points to obtain systolic and diastolic blood pressure values.一種非侵入且非加壓式血壓波量測裝置及方法,該裝置包括:一光體積血容積振幅運算單元,一時間差運算單元,一速率運算單元,以及一運算單元。該方法包括下列步驟:計算光體積血容積波形之特徵點之間的振幅之差;計算心電波形之波峰與光體積血容積波形之特徵點的時間點之差,並計算光體積血容積波形之特徵點之間的時間點之差;根據手長度與心電與光體積血容積時間差值進行計算,以獲得脈波傳遞速率;以及根據脈波傳遞速率、特徵點振幅差值及該等特徵點時間差值中之一進行計算,以獲得收縮與舒張血壓值。10‧‧‧非侵入且非加壓式血壓波量測裝置12‧‧‧光體積血容積量測器14‧‧‧心電圖量測器16‧‧‧特徵點分析單元18‧‧‧光體積血容積振幅運算單元20‧‧‧時間差運算單元22‧‧‧速率運算單元26‧‧‧運算單元28‧‧‧顯示器
