1. blood pressure measuring method based on the photoplethaysmography signal that adopts temperature-compensating is characterized in that may further comprise the steps:

  • 1) carries out blood pressure measurement when calibration, measuring and recording blood pressure is measured required photoplethaysmography signal and determined the formula that embodies of blood pressure measurement formula according to described signal, also writing down the characteristic parameter of described photoplethaysmography signal itself simultaneously;

    And2) when carrying out the actual blood pressure measurement, the described blood pressure measurement formula that the photoplethaysmography signal substitution that the actual blood pressure measurement that records is required is determined by step

         1) is to calculate pressure value, utilize the characteristic parameter of described photoplethaysmography signal itself that blood pressure measurement is carried out the temperature-compensating correction simultaneously, thereby obtain accurate blood pressure measurement.
