Abstract

The invention relates to an analysis method for quantifying a physiological state of the human body, which comprises the following steps: finding n index vectors closest to an input vector in an index database G, and forming a matrix D by the n index vectors; finding an optimization parameter w; solving an estimation vector Vest by utilizing the optimization parameter w, wherein Vest is equal to Dw; for each index vector xj of the matrix D, finding n index vectors closest to the index vector xj, forming a matrix Dj, and finding an optimization parameter wj; solving an estimation vector Vjest by using the optimization parameter wj, wherein Vjest is equal to Djwj; calculating a difference value between the input vector and an estimation vector thereof as a first difference value Vre; calculating a difference value between each index vector xj in the matrix D and an estimation vector Vjest thereof, and taking the difference value as a second difference value; all the second difference values form a difference value library Gre; and calculating a state change index according to the distribution condition of the first difference value Vre in the difference value library Gre.

Description

technical field [0001] The present invention relates to the monitoring and analysis technology of human physiological parameters, in particular to a method and equipment for obtaining basic physiological signals of registration objects through wearable devices, learning continuous physiological signals, and then quantitatively analyzing physiological state changes. Background technique [0002] Guardianship technology has appeared in the last century. From early bedside monitoring, to mobile monitoring, and now to wearable physiological monitoring. In the field of physiological monitoring, an important concept is how to describe and quantify changes in physiological states. Traditional methods often rely on human experience to observe the absolute value changes of one or several physiological indicators. When the observed indicators exceed a certain threshold, the observer will think that the state is abnormal and make the next step. contingency measures. This subjective ...
