Problems solved by technology

[0004] However, for blood pressure measurement methods based on ECG and PPG signals, whether the signal processing and analysis is effective directly determines whether the blood pressure measurement results obtained are accurate. It is very likely that different blood pressure calculation models are used for ECG and PPG signals collected under the same conditions. Blood pressure results with large differences will be obtained; on the other hand, blood pressure measurement cannot get rid of the human body's own conditions, and using a single model to deal with blood pressure measurements of various groups of people will inevitably cause inadaptability and cause large errors

Embodiment Construction

[0041] In order to understand the content of the present invention more clearly, it will be described in detail with reference to the drawings and embodiments.

[0042] Such as figure 1 Shown is a schematic flow chart of the method for generating a blood pressure calculation model based on ECG and PPG signals in the present invention, which mainly includes the following steps:

[0043] Set several disjoint classification subsets based on user attributes; the user attributes include age, history of hypertension, and gender; the classification subsets include A minor, B adult male with a history of hypertension, and C with a history of hypertension Adult female, D adult male without history of hypertension and E adult female without history of hypertension;

[0044] Screen the objects of data collection for each classification subset, that is, screen and determine the suitable data collection volunteers for each classification subset;

[0045] Collect the blood pressure value ...

Abstract

The invention relates to a blood pressure calculation model generation method based on ECG and PPG signals and a blood pressure measurement system, according to a regression analysis principle, characteristics of the ECG and PPG signals are comprehensively analyzed to calculate time and heart rates of pulse waves reaching different positions of a human body, and a human body blood pressure calculation model is established in combination with information such as gender, age and health condition of a subject.

Description

technical field [0001] The invention relates to the technical field of physiological data acquisition devices, in particular to a method for generating a blood pressure calculation model based on ECG and PPG signals and a blood pressure measurement system. Background technique [0002] Blood pressure is a common means to assess a person's health status. The commonly used inflatable sphygmomanometer technology is mature, but the measurement process is cumbersome, and the user experience is poor when used for clinical monitoring. It is difficult for non-professional users to operate accurately by themselves, and the measurement process will cause users Pressure discomfort. [0003] A better alternative is to use ECG and PPG signal sensors for blood pressure measurement, which can achieve non-invasive and continuous blood pressure measurement, and can completely get rid of the shackles of additional components such as cuffs that are necessary for inflatable blood pressure monit...
