Abnormal body temperature detection method and detection system

Abstract

The invention relates to a human body physiological parameter detection technology and particularly discloses an abnormal body temperature detection method and detection system. The detection method comprises the following steps of: detecting the body temperature data of a human body part to be measured in real time; calculating a body temperature data statistic value in an early warning window based on a preset algorithm, comparing the body temperature data statistic value with a preset threshold value, and generating an alarm prompt signal when the body temperature data statistic value exceeds the preset threshold value; and alarming according to the alarm prompt signal. The detection system comprises a body temperature probe, a controller and an alarm, wherein the body temperature probe is used for detecting the body temperature data of the human body part to be measured in real time; the controller is used for calculating the body temperature data statistic value in one early warning window based on the preset algorithm, comparing the body temperature data statistic value with the preset threshold value, and generating the alarm prompt signal when the body temperature data statistic value exceeds the preset threshold value; and the alarm is used for carrying out sound, light or electric signal alarm according to the alarm prompt signal. The detection method and the detection system adopt a contrast body temperature measurement mode and can truly reflect the comprehensive body temperature state of the current measured body.

Description

technical field [0001] The invention relates to the detection technology of human physiological parameters, in particular to a detection method and detection system for abnormal body temperature. Background technique [0002] Body temperature is an important manifestation of human life activities and an important physiological parameter of human metabolism. Studies have found that the temperature of the human body is relatively constant, and the body temperature of normal people fluctuates slightly within 24 hours, generally with a difference of no more than 1 degree. During the day and night, the body temperature fluctuates periodically, with the lowest body temperature at 2-6 o'clock in the morning and the highest temperature at 1-6 o'clock in the afternoon, and the fluctuation amplitude generally does not exceed 1 °C. This kind of circadian rhythm is called circadian rhythm or diurnal cycle. . In medical terms, the temperature of the outermost layer of the body surface,...

Problems solved by technology

[0004] There are also body surface temperature measurements, which are very convenient and fast, but the measurement results are easily affected by the ambient temperature

For example, when the ambient temperature is low, the body surface of the human body will feel very cold. If the body surface temperature at this time is used to reflect the body temperature state of the human body, it is often inaccurate; Blood circulation also affects the body surface temperature

Therefore, although the body surface temperature measurement method can conveniently realize long-term and convenient temperature measurement, and has more measurement positions than the oral cavity, armpit, anus, etc., but because the absolute value of the body surface temperature is more susceptible to Affected by various factors, it cannot accurately reflect the current real body temperature state of the measured body

[0005] Generally speaking, the previous absolute body temperature measurement methods often need to be measured in specific parts (armpit, oral cavity, anus, etc.), which are not suitable for long-term body temperature detection; although the absolute body temperature detection based on the body surface can be better However, since different human bodies and different parts of the same human body have different body surface temperatures, and there is no public literature to clarify the relationship model between the body surface temperature and the actual body temperature, it is difficult to pass the Measure the absolute time value of the body surface temperature somewhere on the body to reflect its real body temperature
