Problems solved by technology
[0004] The disadvantage of the above two methods is that the blood pressure measurement models established by different subjects are easily affected by individual differences. In order to reduce the influence of individual differences on the blood pressure prediction results, blood pressure calibration is usually carried out with the help of cuff blood pressure during implementation. Continuous changes in blood pressure are monitored on the basis of calibration values, but the method of calibrating with cuff blood pressure itself will greatly increase the inconvenience of the user

The present invention provides a non-invasive blood pressure measurement method, device, equipment and system. The method includes: acquiring the personal physical sign data of the user to be tested; acquiring the electrocardiographic signal and pulse wave signal of the user to be tested; wherein, the electrocardiographic signal It is a synchronous signal with the pulse wave signal; the feature value is extracted according to the ECG signal and the pulse wave signal; the personal sign data and the extracted feature value are input into the pre-established blood pressure measurement model to calculate The blood pressure measurement information of the user to be tested is obtained. The present invention directly inputs personalized information related to blood pressure, such as age, height, weight, and body mass index, as features into the training model, and the user can measure blood pressure without calibration when measuring blood pressure, avoiding the inconvenience caused by calibration to the user. inconvenient.
Description
technical field [0001] The present invention relates to the technical field of blood pressure measurement, and in particular, to a non-invasive blood pressure measurement method, device, equipment and system. Background technique [0002] Arterial pressure is an important physiological parameter for diagnosing diseases, observing treatment effects and reflecting the state of the human circulatory system in clinical practice. In the current blood pressure measurement methods such as auscultation method and oscillometric method, the cuff needs to be manually or automatically inflated and deflated to assist the measurement. Such measurement methods will cause discomfort to the user, and the blood pressure value can only be measured once in a period of time. , continuous measurement is not possible. The catheterization method can perform continuous blood pressure monitoring, but it is an invasive blood pressure measurement method, which requires a sensor to be used in the body,...
