  • Clinical thermometer
    Patent number: 5017018
    Abstract: A clinical thermometer which employs an infrared sensor and is constructed so as to prevent the occurrence of a temperature measurement error caused by a change in temperature of a tip portion (of a housing a temperature measuring portion) during temperature measurement. In one embodiment a heat insulator is attached to the tip portion to prevent a rise in temperature of the tip portion. In a second embodiment, the tip portion is formed of a metal of good heat conductivity in the shape of a net for example to improve the heat radiating property of the tip portion, thereby preventing a rise in temperature of the tip portion. In a third embodiments, a temperature sensor is attached to the tip portion to correct a temperature measurement error caused by a change in temperature of the tip portion.
