Physiological parameter detection system and detection method based on optical fiber pad

Abstract

The invention relates to a physiological parameter detection system and a detection method based on an optical fiber pad. The detection system comprises an optical fiber pad, an analysis device, a communication module, a mobile client and a data analysis module. The optical fiber pad feels tiny pressure of a vibration signal of a human body. The pressure exerted on the optical fiber and changes the transmission of light. The analysis device converts the optical signal obtained from the human body pressure on the optical fiber into a voltage signal. The waveform parameters and physiological parameters are transmitted to the mobile client through the communication module. The measured data are stored and displayed. The data analysis module analyzes the measured data, tracks the physiologicalparameter information of the user, judges the physiological status of the user and provides guidance and suggestions. The physiological parameter detection system and method are non-inductive measurement, and stable measurement of respiration and heart rate is realized on the signal processing method, and have good application prospect in the field of health monitoring and chronic disease management.

Description

technical field [0001] The invention belongs to the technical field of physiological parameter detection, and in particular relates to a physiological parameter detection system and detection method based on an optical fiber pad. Background technique [0002] The current detection method of physiological parameters generally adopts electrocardiogram ECG and blood oxygen pulse wave PPG. The sensing unit of the existing detection method needs to stick electrodes on the skin or clamp the probe on the finger to detect the physiological signals. The problem is that Electrodes or probes in contact with the skin for a long time may cause discomfort. [0003] In recent years, non-contact detection methods have attracted much attention. The advantages of the optical fiber sensing detection method are: anti-electromagnetic interference, it can still be used normally in the MRI environment of the hospital or even in a more complex environment, secondly, it is not easy to damage, and t...
