Method, logic operation device and system for approximating patient pulse wave based on non-invasive blood pressure measurement

摘要

The present invention relates to a method for approximating a patient's pulse wave based on non-invasive blood pressure measurement. The method comprises (a) non-invasively measuring a series of n = 1 to N pulse signals pulsen_measured (t) of a patient while applying a clamping pressure clampn (t), and (b) a weighting function. And weighting the measured pulse signal pulsen_measured (t) to obtain a weighted pulse signal pulsen_weighted (t), and (c) adding the weighted pulse signal pulsen_weighted (t) Obtaining an approximate pulseapprox (t) of the patient's pulse wave. The present invention also relates to a logical operation device and system for approximating a patient's pulse wave based on non-invasive blood pressure measurement.
