Body temperature abnormity detection device

The utility model relates to a human body physiological parameter detection technology, and particularly discloses a body temperature abnormity detection device, which comprises a body temperature probe, a controller and an alarm, wherein the body temperature probe is used for detecting the body temperature data of a to-be-detected part of a human body in real time; the controller is used for calculating body temperature statistic in a certain early warning window according to a preset algorithm, comparing the body temperature data statistic with a preset threshold value to obtain a compared result, and generating an alarm prompting signal if the compared result indicates that the body temperature data statistic surpasses a preset threshold value; and the alarm is used for alarming according to the alarm prompting signal. In the body temperature abnormity detection device, a relative body temperature measuring way is adopted, so that the comprehensive body temperature state of a current detected body can be reflected truly.
