SPHYGMOMANOMETER, METHOD FOR CONTROLLING SPHYGMOMANOMETER, AND METHOD FOR DETECTING EFFECTIVE PULSE WAVE

Embodiments of the present disclosure disclose a method for detecting an effective pulse wave and provide a sphygmomanometer and a method for controlling the sphygmomanometer. The method for detecting the effective pulse wave may include: selecting a pulse wave controlling parameter; setting an initial pulse wave controlling parameter; determining at least one pulse wave based on the initial pulse wave controlling parameter, determining a corrected initial pulse control parameter by correcting the initial pulse wave controlling parameter based on at least one pulse wave controlling parameter of the at least one pulse wave; determining at least one subsequent pulse wave based on the corrected initial pulse wave controlling parameter, and further correcting the corrected pulse wave controlling parameter based on at least one pulse wave controlling parameter of the at least one subsequent pulse wave; and repeating above iterative process and continuously correcting the initial pulse wave controlling parameter, and extracting at least one effective pulse wave based on the pulse wave controlling parameter after the correction. The present disclosure may be closer to an actual situation of a measured subject by correcting the initial pulse wave controlling parameter continuously, thereby filtering out a detected invalid pulse wave and avoiding missing detection of the effective pulse wave.
