Research Abstract

The deep body thermometer of the non-heating type when covered the skin surface with a different insulation material of the thickness was developed to measure subcutaneous deep body temperature. The subcutaneous thermal resistance can be neglected from the difference of temperature of a skin body surface and the metal upper side and the thermal resistance ratio of the insulation material. The average of subcutaneous deep body temperature measurements taken using both the non-heating type and then the zero-heat-flow thermometers from the foreheads of 17 healthy subjects were 37. 08℃and 37. 02℃, respectively. In addition, the correlation coefficient between the values obtained by the 2 methods was 0. 970(p<0. 001). These results showed that the non-heating type thermometer can be used for monitoring the deep body temperature as accurately as the conventional method.
