Abstract:
Objective:To discuss the topical action characteristics of the biological transmission of moxibustion heat via temperature collection and numerical modeling.Methods:Temperature of moxibustion was measured at multiple points at a distance of 3 cm to obtain the moxibustion temperature field nephograms by the high-accuracy temperature measure array.Finite element analysis was used to imitate the three-dimensional dynamic distribution of temperature in acupoint tissues.Results:Through numerical analysis,the one-dimensional,two-dimensional and three-dimensional distributions of temperature in human acupoint tissues at 5 min of moxibustion were established.The result showed that moxibustion heat mainly transmitted from the surface of the tissue to the internal,and the influence of moxibustion heat decreased with the depth of the tissue.The analysis of the nephograms of acupoint tissue temperature at 5,10,15 and 20 min of moxibustion showed that with the increase of the moxibustion time,the temperature in acupoint tissues constantly rose,and the transmission depth of moxibustion heat also further expanded inside acupoint.Conclusion:By establishing the three-dimensional dynamic model of heat transmission inside acupoint tissues with the biological parameters of human tissues and the temperature values obtained,this study used finite element analysis software ANSYS 14.0 and discovered the rules in the transmission of heat in body tissues during moxibustion,and the features in moxibustion heat transmission (from the proximal to the distant) and heat penetration (from the surface to the internal).This study provides theoretical and experimental support for the application of moxibustion in clinical practice.
