A kind of blood vessel hardness method for measurement and device,It is to carry out the measurement of blood vessel hardness using a blood vessel hardness measuring equipment,And the method includes the steps of: generating the table shallow artery blood vessel that a string wave vibration signal with a setpoint frequency and a setting maximum displacement amplitude is transmitted to a testee； Sensing reflects the tube wall reagency of the string wave vibration signal and blood pressure pulsations,Frequency dividing amplification Hou obtains the high frequency reagency for reflecting the string wave vibration signal,The numerical digit measurement signal of the reagency sampling value is generated under one sampling frequency of what； The maximum value of the reagency sampling value of corresponding one setting time of what is found out as a maximum reagency； And the maximum reagency is obtained into a blood vessel elastoresistance power divided by the maximum displacement amplitude,Therefore,The maximum reagency that need to only known preset value utilized and measured,Blood vessel elastoresistance power can be calculated.一種血管硬度量測方法及裝置，是利用一血管硬度量測裝置進行血管硬度量測，而該方法包含以下步驟：產生一具有一設定頻率和一設定最大位移振幅的弦波振動信號傳導到一受測者之表淺動脈血管；感測反映該弦波振動信號及血壓脈動的管壁反應力，分頻放大後得到反映該弦波振動信號的高頻反應力，於一取樣頻率下產生該反應力取樣值的數位量測信號；找出對應於一設定時間之該反應力取樣值的最大值作為一最大反應力；及將該最大反應力除以該最大位移振幅以得到一血管抗彈性力，因此，只需利用已知的預設值和所量測之最大反應力，即可算出血管抗彈性力。
