Design and Application of System for Skin Temperature Oscillation Analysis and Microvascular Function Evaluation
摘要
Abstract
Objective To design and achieve a skin temperature oscillation analysis system for the evaluation of microvascular regulatory functions.Methods The local thermal stimulation was used by skin temperature oscillation analysis system,composed of portable instruments and analysis software to induce human skin to produce congestion reaction.The skin temperature change signals before and after congestion reaction were collected in real time,and the amplitude of skin temperature oscillation based on continuous wavelet transform was analyzed,and the evaluations of skin microvascular endothelial,nerve and myogenic regulatory functions were realized finally.Results Experimental studies using developed system found that thermal stimulation at 40-41℃significantly enhanced the intensity of skin temperature oscillations.The fluctuation amplitude of skin temperature in the endothelium(0.0095-0.0200 Hz),neurogenic(0.02-0.05 Hz)and myogenic(0.05-0.14 Hz)frequency bands were 2.20,4.28 and 2.77 times of those without thermal stimulation,respectively.Conclusion This study verifies the enhanced amplitude of skin temperature oscillations under thermal stimulation conditions,which can be used to quantify the functions of skin microvascular movement regulation.The skin temperature oscillation analysis system designed and developed in this paper provides an effective tool for the evaluation of microvascular regulatory functions.关键词
