Unified default value, or can be according to the human body physiological parameter and the pre-stored Human Physiology of processing unit 30 of each individual
Parameter table corresponding with each numerical value obtains, and is determined to reach higher precision according to Human Physiology information.In some embodiments,
The value of above-mentioned each initial time can also be obtained by actual calibration, and specific scaling method is that user wears the present invention
Described integrated sensor carries out the acquisition of PPG signal and ECG signal, while being set using another blood pressure signal acquisition
It is standby, synchronous acquisition human blood-pressure signal.PTT, PIR, MBP that the period integrated sensor measures are PTT0、PIR0、MBP0, separately
That one blood pressure signal acquisition equipment measures, DBP, SBP are DBP0、SBP0.In this way, more accurate PTT can be obtained0、
PIR0、MBP0、DBP0、SBP0。
In the present invention, one or more pulse wave sensors can be set in each electrocardioelectrode.The arteries and veins
Wave sensor 10 of fighting is arranged with EGC sensor 20 in same test position, and is linked into same processor, therefore
In a certain period, the time interval of pulse wave signal peak value and ECG signal ECG signal peak value is pulse propagation time
PTT, does not need individually to synchronize that allow for pulse wave signal and ECG signal fully synchronized on the time of acquisition signal,
Accurately measure PTT signal.
