Abstract

The invention relates to the technical field of medical apparatuses, in particular to a method for analyzing pulse wave shape quality. The method sequentially comprises the following steps of A, according to similarity, performing cluster dividing on various pulse wave shapes; B, comparing sample number in each cluster obtained in the step A, and selecting the clusters having the largest sample quantity; and C, if the number of the clusters having the largest sample quantity is one, determining that the pulse wave shape quality to be good, if the number of the clusters having the largest sample quantity is greater than or equal to two or smaller than four, determining that pulse wave shape quality to be medium, and if the number of the clusters having the largest sample quantity is greaterthan or equal to four, determining that the pulse wave shape quality is bad. The pulse wave shape is subjected to cluster dividing, and according to the number of the clusters having the largest sample quantity, the pulse wave shape quality is determined, so that the pulse wave shape quality can be quantified.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a method for analyzing the quality of a pulse wave waveform. Background technique [0002] Many wearable devices detect heart and blood vessel-related parameters such as heartbeat, blood pressure, stroke volume, and arterial elasticity through the waveform of the arterial pulse wave. If the quality of the pulse waveform is not good, that is, the shape of the pulse waveform is incorrect, then the calculated related parameters will also be incorrect, leading to misleading users. Therefore, it is necessary to analyze the quality of the pulse waveform so that the user can know the quality of the pulse waveform and refer to the reliability of various parameters. Contents of the invention [0003] The present invention provides a method for analyzing the quality of the pulse waveform aiming at the problems of the prior art. [0004] The present invention adopts the follow...
