Present apparatus system changes pressure using the air bag of sphygmomanometer, cun,guan,chi position is taken with the array sensor of its lower installation again, measurement is floating, in, the signal amount of eddp pulse, resulting signal amount is first passed through into high pass and low-pass filter filtering, signal digitlization is transferred to computer using analogy Hou and is shown over the display. 本裝置係利用血壓計之氣囊改變壓力，再以其下加裝之陣列式感測器取寸、關、尺位置，測定浮、中、沉脈的訊號量，將所得的訊號量先經過高通及低通濾波器過濾，再經過類比後將訊號數字化轉入電腦顯示在顯示器上。
