Blood vessel ageing index measuring and analyzing system, and measuring and analyzing method thereof

A blood vessel ageing index measuring and analyzing system, comprising:

• a pressure applying unit operable in one of a pressure-applying mode, where said pressure applying unit is configured to apply external pressure to a limb of a subject, and a pressure-releasing mode, where said pressure applying unit is configured to release the limb of the subject from the external pressure;
• a measuring unit associated operatively with said pressure applying unit and configured to output a standard radial artery pulse signal based upon a pulse of the subject that was measured prior to operation of said pressure applying unit in the pressure-applying mode, and to output a comparative radial artery pulse signal based upon a pulse of the subject that was measured after operation of said pressure applying unit in the pressure-releasing mode;
• a front end signal processing unit coupled to said measuring unit, configured to perform filter processing upon the standard radial artery pulse signal and the comparative radial artery pulse signal outputted by said measuring unit to obtain processed standard and comparative radial artery pulse signals, and further configured to digitize the processed standard and comparative radial artery pulse signals to generate a digital standard radial artery pulse signal and a digital comparative radial artery pulse signal;
• and
• a back end signal analyzing unit coupled to said front end signal processing unit, configured so as to determine an average value of a standard pulse area with reference to the digital standard radial artery pulse signal, and so as to determine a maximum value of a comparative pulse area with reference to the digital comparative radial artery pulse signal, and further configured to obtain a first blood vessel ageing index based on the average value of the standard pulse area and the maximum value of the comparative pulse area determined thereby.
