Physiological parameter measurement mechanism

Abstract

The present invention discloses a physical parameter measuring device. The present invention comprises a first judging module, the first judging module is used to judge whether the changes of the pulse wave characteristic value are in line with the set conditions, if yes, a prediction module is triggered to calculate the blood pressure prediction value, and if no, a blood pressure value measuring module is triggered to regain the reference blood pressure value; a second judging module, the second judging module is used to judge whether the regained reference blood pressure value is within the prediction range, if yes, the prediction module is triggered to calculate the blood pressure prediction value, and if no, a generating module is triggered to regenerate the blood pressure prediction rules. The present invention can make continuous synchronous measurement of the physical parameters which reflect the function of the cardiovascular system and adopts a continuous synchronous calibrating mechanism particularly for blood pressure measurement, thus not only reducing the impact of the changes of other physical parameters on the relationship between the pulse wave characteristic value and the blood pressure, but also automatically starting the measurement of the reference blood pressure value in the continuous measuring process so as to ensure more accurate continuous measurement.

Description

technical field [0001] The invention relates to a physiological parameter measuring device, in particular to a physiological parameter measuring device which can be used for continuous measurement. Background technique [0002] The monitoring of physiological parameters, especially the daily monitoring of key physiological parameters reflecting the function of the cardiovascular system, can enable people to early detect cardiovascular diseases that may lead to serious consequences. Physiological parameters that reflect the function of the cardiovascular system usually include arterial blood pressure, rate of change of arterial blood pressure, heart rate, rate of change of heart rate, respiratory rate, rate of change of respiratory rate, and blood oxygen saturation. In the prior art, the monitoring of physiological parameters such as heart rate, respiratory rate and blood oxygen saturation has achieved continuous and non-destructive measurement, while the measurement of blood...

Problems solved by technology

However, using this measurement method has the following disadvantages: First, the cuff will cause discomfort to the measured subject

If the cuff is used frequently, the tissue and blood vessels under the cuff may be damaged due to frequent compression; second, because the cuff takes a certain amount of time to inflate and deflate, the cuff-type device takes a long time to complete a measurement , so they cannot achieve continuous measurement of blood pressure; third, because the inflation and deflation of the cuff will affect the tension of blood vessels, thus affecting the accuracy of measurement
