Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of human health parameter measurement, and in particular to a system and method for measuring core body temperature and multi-modal health parameters. BACKGROUND

[0002] Currently, most wearable devices mainly focus on the detection of conventional physiological parameters such as heart rate, pulse and blood oxygen. However, core body temperature, as one of the four vital signs of the human body, is not only an important basis for determining the health status of the human body, but also a necessary condition for maintaining normal metabolism and life activities. Therefore, effective monitoring of the core body temperature of the human body has become a crucial research topic.

[0003] In the field of clinical medicine, the core body temperature mentioned refers to the average core temperature, i.e. the temperature measured in a resting state for the main organs of the human body (such as the brain, heart, lungs, liver, etc.), and the core body temperature can better reflect the true state of the internal environment of the human body and is more closely related to human metabolism. However, in daily life, people generally measure the temperature of the armpit, oral cavity and forehead, etc. Strictly speaking, these belong to the body surface temperature, because under this measurement method, the thermometer only reflects the surface temperature of the measurement site, and is easily affected by various factors such as the environment, measurement method, clothing, etc., so there will be certain differences with the core body temperature. In comparison, the measurement of the temperature of the deep layers of human tissue (not less than 5mm deep from the body surface) can more accurately reflect the core body temperature and has more reference significance for indicating the health of the human body.

[0004] In view of the above problems, after comprehensive analysis of the current research status of core temperature monitoring at home and abroad, the existing technology can be summarized into two categories. The first is direct measurement, i.e. measuring the temperature of a part of the human body by direct measurement to approximate the core temperature of the human body. This method is relatively simple to operate, but has large errors and is easily affected by external factors. The second is indirect estimation, which uses physiological data such as body surface temperature and heart rate to calculate and analyze the actual temperature inside the human body by modeling. This method often needs a large amount of experimental data of the population as a reference value, and there are large differences according to the different groups of the measured objects, which cannot be universally applicable.
