Electronic clinical thermometer with quick temperature estimating device

摘要

An electronic clinical thermometer has one of two temperature measuring devices each for measuring a live body temperature. A temperature estimating device estimates an equilibrium body temperature from a first data item related to change in temperature measured by the temperature measuring device during an initial period within a specified time such as about 20 seconds from the start of a measurement and a second data item related to a change in temperature measured by the temperature measuring device after the initial period. If two temperature measuring devices are used, the first data item may be related to the difference between temperatures measured by these two temperature measuring devices and the second data item may be related to the time-rate of change in temperature measured by either of the two temperature measuring devices. The first data item may be a value obtained from the linear relationship between the temperature value measured by either of the two temperature measuring devices and the difference between them.
