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.
