目的:研究维医沙疗治病中的热量传递规律.方法:建立维医沙疗过程中人体及沙体中热量传递过程的局部和整体热物理模型,数值模拟沙疗中人体及沙体的温度变化.结果:得到了沙疗过程中人体组织和沙层局部温度随时间的变化规律;在沙疗初始阶段,沙体表面和人体表面处沙子的温度变化较大,而深度5 cm以下的沙子温度变化很小;皮肤层温度在沙疗初始阶段明显升高,之后略有下降;当埋沙厚度大于10 cm后,增加埋沙厚度对沙疗过程中人体内温度变化的影响不大;沙疗温度过高会对人体产生热损伤,当沙体温度高于64.6 ℃,沙疗进行30 min时,人体皮肤将会产生I度烧伤.结论:在沙疗时应合理地选择沙体温度、埋沙厚度和治疗时间.

Objective To investigate the mechanism of heat transfer process in sand therapy in Uyghur medicine. Methods A mathematical model was developed to describe the heat transfer process between human body and the sand during sand therapy. Temperature field was numerically simulated and analyzed based on this model. Results Temperature field in both human tissues and sand was calculated. The surface temperature of the sand and skin surface changed significantly at the beginning of the sand therapy, while sand temperature (5 cm deep) almost kept constant. The skin temperature dramatically increased at the beginning of the sand therapy and then slightly dropped. When sand was deeper than 10 cm, the thickness of sand would not influence the temperature field in human tissues during sand therapy. High initial temperature of sand might cause harmful skin burn. Threshold skin burn occurred if initial temperature of sand was higher than 64.6 ℃ and if the therapy lasted more than 30 minutes.Conclusion Temperature fieled in human tissues varies significantly with the initial temperature of sand, thickness of sand, and duration of therapy.
