An automatic extraction apparatus for a pulse signal and an extraction method thereof are provided. The apparatus comprises a bracket, three lifting devices matched with three parts of Cun, Guan, and Chi of the human body being mounted on the bracket, each lifting device comprising an electric motor vertically fixed on an upper portion of the bracket, a screw being fixed at a lower end of a spindle of the electric motor, a sleeve being connected to screw threads at a lower portion of the screw, the sleeve being mounted at a lower portion of the bracket and only capable of sliding up and down relative to the bracket, and a pressure sensor being fixed at a lower end of the sleeve a fixing component for constraining the apparatus on the three parts of Cun, Guan, and Chi of the human body and a control circuit board for controlling the pressure sensor to collect pulse signals under different pressures. The apparatus is fixed at the three parts of Cun, Guan, and Chi of the human body through the fixing component, the control circuit board controls the lifting devices to boost pressures at the three parts of Cun, Guan, and Chi of the human body respectively, and the pressure sensor acquires a pulse pressure wave form corresponding to each part, thereby implementing automatic extraction of pulse signals at the three parts of Cun, Guan, and Chi of the human body.本發明公開了一種脈搏信號自動提取裝置及其提取方法,該裝置包括支架,支架上安裝有三個與人體寸、關、尺三個部位的位置相匹配的升降裝置,每個升降裝置包括豎直固定在支架上部的電機,電機轉軸下端固定有絲杠,絲杠下部螺紋連接有套筒,套筒安裝於支架下部且只能相對於支架上下滑動,套筒下端固定有壓力傳感器;用於將該裝置束縛於人體寸、關、尺三個部位上的固定部件;用於控制壓力傳感器在不同壓力下進行脈搏信號採集的控制電路板。通過固定部件將該裝置固定於人體寸、關、尺三個部位,通過控制電路板控制升降裝置分別對人體寸、關、尺三個部位進行加壓,由壓力傳感器獲取對應部位脈壓波形,從而實現人體寸、關、尺三個部位的脈搏信號的自動提取。1‧‧‧支架3‧‧‧固定部件6‧‧‧上蓋204301‧‧‧固定底板602‧‧‧鎖銷603‧‧‧鎖孔機構
