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.Appareil dextraction automatique dun signal de pouls et procédé associé, lappareil comprenant un support, trois dispositifs de levage correspondant à trois parties du corps, à savoir le pouce (cun), la barrière (guan), et le pied (chi), montés sur le support, chaque dispositif de levage comprenant un moteur électrique fixé vertical sur une partie supérieure du support, une vis fixée à une extrémité inférieure dun axe du moteur électrique, un manchon raccordé aux filets de la vis dans une partie plus basse de la vis, le manchon étant monté sur une partie inférieure du support et ne pouvant coulisser que vers le haut
