Embodiment Construction

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] The pulse signal waveform refers to the pressure that the heart causes the blood to flow in the artery to form a periodic change in the arterial wall during the contraction and relaxation process. By using a specific sensor to record the data of this pressure change in real time, use these data to draw The graph of is called pulse wave. Relevant research results show that the human pulse wave signal will change significantly with the change of blood pressure, so there is a corresponding relationship between human blood pressure and human pulse wave signal, and the pulse wave signal can be used to perform soft blood pressure measurement.

[0034] Such as figure 1 As shown, it is a schematic flowchart of a met...

Abstract

The invention relates to a blood pressure prediction method and in particular relates to a human body blood pressure prediction method based on pulse wave. The human body blood pressure prediction method comprises performing filtering and accumulation and superposition processing and effectiveness judgment on a pulse wave signal and constructing a regression prediction model of blood pressure values by use of the least square method with the harmonic amplitude of the effective pulse wave signal as a characteristic parameter; the prediction process is simple and the prediction error is low; the blood pressure prediction method can be widely applied to family life.

Description

technical field [0001] The invention relates to a method for predicting blood pressure, in particular to a method for predicting human blood pressure based on pulse waves. Background technique [0002] As an important parameter of human physiology, blood pressure can reflect the condition of the human heart and the function of blood vessels. People can diagnose the disease through abnormal blood pressure, and can also use it to observe the effect of treatment, or to predict the future of the disease. forecast changes. The change of human blood pressure is related to many reasons, such as: menstrual cycle, emotional changes, and various internal diseases or external stimuli. In the process, it is inevitable that there will be some discrepancies with the actual situation, but when using the uninterrupted measurement method, these fluctuations can be eliminated, and the judgment can be made by looking at the blood pressure changes within a period of time, which is more accurat...
