Abstract
Providing a probe for an electronic clinical thermometer, which can measure a surface temperature and a deep body temperature of a human body securely in short time, the probe includes a cylindrical housing, a bottomed metal pipe fitted into a top end of the cylindrical housing, and a substrate having two thin-film heat-sensitive elements arranged perpendicularly on an inner wall of the bottomed metal pipe so as to fix one side edge of the substrate tightly on the inner wall. By measuring heat flux between the two thin-film heat-sensitive elements, the surface and the deep body temperatures of the human body can be predicted by applying the measured values into a heat conduction equation without waiting the sensor to reach in heat balance.
Claims7
A probe for an electronic clinical thermometer, comprising:
- a cylindrical housing;
- a metal pipe having a closed end and being fitted with an end of said cylindrical housing;
- and
- a temperature sensor being inserted and fixed in said metal pipe for measuring heat flux according to heat flow between a human body and the temperature sensor to predict a body temperature;
- wherein said temperature sensor includes a substrate and two thin-film heat-sensitive elements being formed on the substrate along the heat flow from a side edge of the substrate,
- wherein said substrate is arranged perpendicularly on an inner wall of the metal pipe so as to fix the side edge of the substrate tightly on the inner wall for thermally coupling the inner wall of the metal pipe and the substrate.
