A new method for continuous measurement of blood pressure (BP) via selecting characteristic parameters of pulse wave pertinent to BP is presented in this paper. In order to validate the precision of the measurement, we have developed a Tonometer. The results of the instrument based on this method are precise if the subjects are at rest. This instrument could be used for BP monitoring of critically ill patients and in common medical researches; it might be applied to BP monitoring during spaceflight and in daily life after movement artifact being restrained.
