摘　　要：目的建立一种简便易行的,通过皮肤温度估计体核温度的连续、动态、长时间无创体温监测新方法。方法提出通过人为改变环境温度(Te)而获得个性化的绝热材料热阻(Re)对体表组织热阻(Rc)比值的途径,实现从皮肤温度(Ts)中扣除环境温度(Te)影响,从而达到从皮肤温度(Ts)测值中估计体核温度(Tc)的方案和具体测量方法,并用自行设计的模拟体温发生器对此方案进行了可行性和准确性验证。结果体核温度估算值和体核温度测量值的相关系数为0.996,估值误差小于0.2℃。结论该方案估计的体核温度很好地反映并跟随实际体核温度变化,在实现体温各异性测量中消除了环境温度变化所带来的影响,实现了体核温度长期、动态、无创的监测。Objective To establish a new method of noninvasive core temperature measurement estimated from the skin temperature for continous, dynamic, long time body temperature monitoring. Methods In order to estimate core temperature（Tc） from skin temperature（Ts） ,the paper simulated an environmental temperature（Te） change. From the change, the paper obtained the thermoresistance ratio of adiabator（Re） and body surface tissue（Rc）, at the same time, deducted environmental temperature（Te） influences from the skin temperature（Ts）. The feasibility and accuracy of the method was tested by a self-made body temperature simulator. Results The coefficient correlation of the estimated core temperature and the real core temperature was 0. 996. The measurement error was smaller than 0.2℃. Conclusion The estimated core temperature reflects and follows the real core temperature changes well. The method reflects the individual variation in core temperature measurement and deducts the environmental temperature change influences, it realizes continuous, dynamic, long time core temperature monitoring.
