Ear type clinical thermometer of infrared ray utilization

摘要

(57) Abstract As for the ear type clinical thermometer of infrared ray utilization, the thermopile sensor (40) and the thermister (44) and it includes with the temperature decisive circuit (14) where it is installed in the detection head housing (12) and the concave section and the concave section which were formed to the heat sink (30) and the heat sink (30). The concave section picture forming does the aperture where sight of the thermopile sensor (40) is restricted. Calorific capacity and conductivity of the thermopile sensor (40) and the heat sink (30) are selected, during thermometry in order for the output signal of the thermopile sensor (40) to be stabilized. The temperature decisive method of using the ear type clinical thermometer continuous measurement, remembered measurable quantity in the up time window, levelled the measurable quantity inside the movable window, it decides, outputs average temperature whether or not mean value was stabilized. The method of calculating object temperature decides the temperature of the cold junction of the thermopile, (40) inspects the inclination and bias of the thermopile (40) on the basis of the temperature of the cold junction, measures the output of the thermopile, (40) calculates object temperature on the basis of the rectilinear relationship with object temperature and output. The relationship in this straight line the picture is formed by bias and inclination.
