Electronic thermometer

摘要

An electronic thermometer includes a hollow probe provided at its longitudinal tip with a temperature measuring unit having a temperature sensor for sensing a temperature, electrodes neighboring to the temperature sensor and arranged in the hollow of the probe, and a determining unit for determining whether temperature measuring unit is in appropriate contact with a measurement target portion of a user or not, based on a change in electrostatic capacity sensed using the electrodes.

主权项

1. An electronic thermometer comprising:
a hollow probe including a temperature measuring unit having a temperature sensor for sensing a temperature at the longitudinal end of said hollow probe; an electrode arranged in a hollow of said probe without being exposed to an outside of said probe and located near said temperature sensor and said electrode being arranged at a distance in a longitudinal direction of the probe from the position where said temperature sensor is arranged; a body temperature predict unit for predicting a user's temperature based on the temperature sensed by said temperature sensor of the temperature measuring unit; and a determining unit for determining whether said temperature measuring unit is in appropriate contact with a measurement target portion of the user or not, based on a change in electrostatic capacity sensed using said electrode and a change in temperature sensed by said temperature sensor.
