Embodiment Construction

[0071] figure 1 is a flowchart of a method for measuring the continuous rate of change of blood pressure according to an embodiment of the present invention. like figure 1 As shown, in this embodiment of the present invention, it mainly includes the step 101 of collecting signals from the human body, the step 102 of signal preprocessing, the step 103 of determining the corresponding waveform feature points in the signal, determining the FY distance, pulse wave transmission time and YG Pitch sequence step 104, step 105 of determining FY pitch rate of change (FYV), pulse wave transit time rate of change (PTTV), heart rate rate of change (HRV), and blood volume rate of change (VR), based on the determined FYV, PTTV , HRV and VR and other parameters to directly calculate the blood pressure change rate (BPV) step 106, calculate the blood pressure relative change rate step 107, use the FY interval (or in combination with other parameters) to calculate the blood pressure step 108, a...

Abstract

The invention discloses a method for measuring blood pressure change rate which comprises the steps of, (1) collecting a series of signals related to human body pulses wave production and transmission characteristics, (2) obtaining characteristic parameter sequence of the collected signal, (3) determining blood pressure parameter according to the obtained signal characteristic parameter sequence.

Description

technical field [0001] The present invention relates to a method for measuring blood pressure, in particular to a method for measuring the change rate of blood pressure corresponding to each or multiple consecutive heart beats. Background technique [0002] Measuring blood pressure is a basic method for understanding health conditions and observing conditions, especially necessary for middle-aged and elderly people suffering from cardiovascular diseases. Blood pressure tends to fluctuate greatly in a day or even in a certain period of time, so it is difficult to provide accurate and reliable data and enough useful information with a single or a small amount of measurement, let alone calculate the blood pressure corresponding to the heartbeat. various rates of change. Specifically, each heartbeat will generate a corresponding blood pressure value, that is to say, the blood pressure value actually changes continuously like the heart rate and corresponds to one of them, so the...
