Document Type and Number:
WIPO Patent Application WO/2000/035339
Kind Code:
A1
Abstract:
A radiation clinical thermometer capable of measuring the body temperature more accurately than conventional by considering the infrared radiation emitted from the end of a probe part and reflected by the ear drum and external canal. The thermometer has temperature calculating means for calculating the body temperature according to a predetermined calculation equation based on the emissivities of the ear drum and external canal which are below one, the output of infrared sensing means, and the output of temperature measuring means.
