高精度温度制御加熱装置による温熱治療とその評価

摘要

Moxibustion, one of thermal therapy of oriental medicines, has several problems such that temperature distribution is not uniform, treatment temperature cannot be controlled and smoke is emitted. Therefore, in order to solve these problems, we developed precise thermal heat transfer control device and applied it to clinical medicine as a substitute of conventional moxibustion. Numerical simulation of temperature distribution under the skin when abdominal region is heated is carried out. The abdominal heating controller developed in this study has the effect equal to moxibustion and can heat the treatment region of human skin uniformly. The treatment effect of the device was evaluated on clinical experiment, then it was found that these devices can treat ileus, diarrhea and so on. Optimal temperature for thermal therapy was examined about parameters of sex, BMI and age. Temperature distribution of heated abdominal region is calculated by 2 D axisymmetric model considering bio-heat generation. It is confirmed that thermal effect cannot reach the viscera from the calculation result.%灸治療は，中国を中心にアジア各地で何千年以上rnの間，漢方医学における温熱治療の手法のーつとしrnて用いられてきた．灸治療は，ヨモギの葉の要かrnら取れるもぐさを皮膚上部で燃焼させることによっrnて径穴（いわゆる「ツボ」）や患部を加熱し，様々rnな症状を軽減するという治療である．
