A vital sign measurement device includes a sensor fixation device, an optical sensing system, and an output unit. The sensor fixation device is adapted to be placed against an anatomical location of a subject, within which is an artery. The optical sensing system includes an optical source, an optical refractor, and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device. The optical sensing system is positioned with respect to the sensor fixation device to sense movement corresponding to an arterial pulse when the sensor fixation device is placed against the anatomical location of the subject. The optical sensing system can sense anatomical pulse from the movement, bending or compression of at least one portion of the optical sensing system relative to other portions of the other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector. The output unit receives, from the optical sensing system, an input indicative of movement corresponding to an arterial pulse and generates, using the input, a measure of the vital sign.一種生命徵象測量裝置包含一感測器固定裝置、一光感測系統及一輸出單元。該感測器固定裝置係經調適以設置靠在一試驗體之解剖位置上,而其內係一動脈。該光感測系統包含一光源、一光折射器及一光偵測器,所有該等裝置皆由該感測器固定裝置所固持,並且隨著該感測器固定裝置而移動。該光感測系統係經相對於該感測器固定裝置所定位,藉以在當該感測器固定裝置被設置靠在該試驗體之解剖位置上時,能夠感測到對應於一動脈脈搏的移動。該光感測系統可自該光感測系統之至少一部分相對於該光感測系統之其他部分的移動、彎折或壓縮而導致該光偵測器所接收之光信號的變化,感測到一動脈脈搏。該輸出單元自該光感測系統接收一表示對應於一動脈脈搏之移動的輸入,並且利用該輸入產生一生命徵象的測量值。102...感測器固定裝置104...光感測系統106...輸出單元108...電線112...試驗體114...顯示裝置116...通管
