Blood pressure measuring method and embedded device for realizing method

Abstract

The invention provides a blood pressure measuring method. The blood pressure measuring method comprises the steps of obtaining the pulse contour of a measured object and extracting a plurality of characteristic points from the pulse contour according to preset rules; selecting an optimum blood pressure measuring model group from a model library according to the physiological indexes of the measured object and loading the optimum blood pressure measuring model group; running the optimum blood pressure measuring model group to perform calculation according to the characteristic points to obtain the blood pressure parameters of the measured object. Correspondingly, the invention additionally provides an embedded device capable of realizing the blood pressure measuring method. By implementing the blood pressure measuring method, different optimum blood pressure measuring model groups which are suitable for different measured objects can be correspondingly selected aiming at different types of measured objects, so as to obtain more accurate blood pressure parameters.

Description

technical field [0001] The invention relates to the field of medical measuring instruments, in particular to a method for measuring blood pressure and an embedded device for realizing the method. Background technique [0002] Human physiological parameters are a series of indicators to measure the physiological state of the human body in medicine, including pulse parameters, blood pressure parameters, blood oxygen parameters, blood sugar parameters, etc. Physiological parameters reflect the physical condition of the human body macroscopically, and are very important for disease prediction and body maintenance. early warning and guidance. Among them, for the measurement of blood pressure parameters, the following two methods are mainly adopted in the prior art: one is to measure the blood pressure parameters by using a pressure sphygmomanometer, and the other is to use the pulse wave transit time to measure the blood pressure parameters. [0003] Although people can measure ...

AI Technical Summary

Problems solved by technology

[0003] Although people can measure their own blood pressure parameters by using the above two blood pressure measurement methods, there are certain shortcomings in these two blood pressure measurement methods

For the first method, using a pressure sphygmomanometer to measure blood pressure parameters is likely to cause great interference to the human body, and it cannot achieve the purpose of continuous measurement

For the second method, measuring blood pressure using pulse wave transit time has a large error, and systolic blood pressure cannot be measured at the same time
