Definitions
- the present invention relates to a radiation thermometer.
- the outer ear which is a hole in the living body, is selected as a measurement site, and the body temperature of the living body is measured by detecting infrared rays from the eardrum and ear canal to be measured with an infrared sensor
- a radiation thermometer has been proposed as a radiation thermometer.
- This radiation thermometer is a thermometer in which a probe is inserted into the external auditory canal, which is a hole in a living body, and infrared light incident on the probe is detected by an infrared sensor. Even if the probe is inserted into the ear canal, it does not face the eardrum completely, so both the eardrum temperature and the eardrum temperature are measured. A temperature close to the eardrum temperature can be measured.
- thermometer measures the temperature at the moment when the measurement switch is pressed with the probe inserted in the ear canal in advance. It is measured only once. However, the probe is usually left indoors before measurement, so the temperature is often lower than the eardrum temperature, but when the probe was inserted into the ear canal, the temperature was almost the same as the eardrum temperature until then. The phenomenon occurs that the ear canal is cooled by the probe. Therefore, the radiation thermometer disclosed in the above-mentioned publication measures the temperature of the cooled ear canal together with the temperature of the eardrum, and cannot measure the temperature of the eardrum accurately.
- the actual c this radiation clinical thermometer radiation thermometer for measuring a near have temperature the eardrum temperature is disclosed in JP-A-2 2 6 3 1 2 5 No. peak hold It has a circuit and is configured to display the highest temperature among the measured temperatures. To do so, the temperature measurement is started by pressing the measurement switch before inserting the probe into the ear canal. This Since the temperature is measured before the probe is inserted into the ear canal by the above operation, the temperature of the ear canal before the ear canal is cooled before the probe is inserted is not measured instead of the eardrum temperature and the cooled ear canal temperature. A temperature close to the eardrum temperature, that is, a peak temperature can be measured.
- the peak hold circuit of the radiation thermometer disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 2-263125 is designed to be reset each time the measurement switch is pressed and the temperature measurement operation is started. If the probe is inserted into the ear canal and the measurement switch is pressed again, the maximum temperature detected at the time of insertion will be reset, and the maximum temperature measured after the second operation of the measurement switch Is displayed, but this display temperature is also the eardrum temperature and the ear canal temperature cooled by the probe, and there is a problem that the temperature becomes lower than the actual body temperature.
- the present invention has been made in view of the above points, and the temperature measurement is started by operating the measurement switch before inserting the probe into the ear canal, and the highest temperature among the measured temperatures is defined as the body temperature.
- the displayed radiation thermometer a radiation thermometer that determines whether the measurement switch has been operated properly and notifies the operator of an erroneous operation or that does not display the temperature measured due to erroneous operation should be provided. It is intended to provide.

Since the ear canal becomes higher than the value T f (for example, 32 ° C) and then the ear canal is cooled by the probe, the second and third temperature data T 2 and T 3 are smaller than the first measurement data T 1 become. Therefore, the comparing means 63 is determined to be an erroneous operation.
