Abstract

The invention provides a blood pressure estimating method and device, and relates to the technical field of medical care. The blood pressure estimating method comprises the following steps of obtaining input parameters, wherein the input parameters comprise an encode signal, characteristic parameters and multi-scale entropy, the encode signal is a signal obtained after first signal data is encodedby a self encoding machine, the first signal data comprises a first electrocardiosignal and a first pulse wave signal, the first electrocardiosignal is an electrocardiosignal of a user, the first pulse wave signal is a pulse wave signal of the user, the characteristic parameters are physiologic signal indexes of the first signal data, and the multi-scale entropy represents the complexity of the first signal data; and inputting the input parameters to a blood pressure estimation model to obtain an estimated blood pressure, wherein the estimated blood pressure has corresponding relation with the encode signal, the characteristic parameters and the multi-scale entropy. According to the blood pressure estimating method disclosed by the invention, extraction of various types of data is performed on the first signal data of the user, and various types of data is used for estimating the blood pressure of the user, so that the precision rate of blood pressure estimation can be improved.

Description

technical field [0001] The present invention relates to the field of medical technology, in particular to a method and device for estimating blood pressure. Background technique [0002] As an important physiological parameter of the human body, blood pressure can reflect the physiological health of the human body and is also an important basis for evaluating the health of the heart and blood vessels. Therefore, timely attention to changes in blood pressure is related to people's health. [0003] In the prior art, there are many methods for measuring blood pressure. Among them, a more convenient method is: collect pulse wave and blood pressure value to train the model, and estimate the blood pressure value through the trained model. [0004] Although the modeling method in the prior art can estimate human blood pressure conveniently and quickly, its accuracy needs to be improved. Contents of the invention [0005] The object of the present invention is to provide a meth...
