ELECTRONIC THERMOMETER AND BODY TEMPERATURE MEASUREMENT METHOD

摘要

An electronic thermometer includes first and second body surface temperature measurement portions to measure first and second values of a measurement object, first and second reference temperature measurement portions to measure values at each position having a predetermined thermal resistance relative to a measurement position of the first and second values, and having a first and second thermal resistance relative to the open air, third temperature measurement portion to measure a third value at a different position from the previous values, correction portion to correct the obtained values; and core body temperature calculation portion to calculate a value of the object using the obtained values.

1. An electronic thermometer comprising:
first body surface temperature measurement portion subjected to measure a first body surface temperature of a measurement object; first reference temperature measurement portion subjected to measure, as a first reference temperature, a temperature at a position having a predetermined thermal resistance value relative to a measurement position of the first body surface temperature, and having a first thermal resistance value relative to the open air; second body surface temperature measurement portion subjected to measure a second body surface temperature at a body surface position different from the measurement position of the first body surface temperature; second reference temperature measurement portion subjected to measure, as a second reference temperature, a temperature at a position having a predetermined thermal resistance value relative to the measurement position of the second body surface temperature, and having a second thermal resistance value different from the first thermal resistance value relative to the open air; third temperature measurement portion subjected to measure a third temperature at a different measurement position from the first body surface temperature and the second body surface temperature; temperature correction portion subjected to correct the first body surface temperature, the first reference temperature, the second body surface temperature, and the second reference temperature using the third temperature; and core body temperature calculation portion subjected to calculate a core body temperature of the measurement object using the first body surface temperature, the first reference temperature, the second body surface temperature, and the second reference temperature corrected by the temperature correction portion.
