Description

Technical Field

[0001] The present invention 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 Art

[0002] Currently, most wearable devices focus on detecting conventional physiological parameters such as heart rate, pulse and blood oxygen. However, core body temperature, as one of the four major 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, achieving effective monitoring of human core body temperature has become a crucial research topic.

[0003] In the field of clinical medicine, the core body temperature mentioned usually refers to the average core temperature, that is, the temperature measured from the main organs of the human body (such as the brain, heart, lungs, liver, etc.) in a resting state. The core body temperature can better reflect the true state of the human internal environment and is more closely related to human metabolism. However, in daily life, people generally measure the temperature of the armpits, mouth, forehead and other parts. Strictly speaking, these belong to the surface temperature of the body, because under this measurement method, the thermometer only reflects the surface temperature of the measurement part, and it is easily affected by various factors such as the environment, measurement method, clothing, etc., so there will be a certain difference from the core body temperature. In comparison, the measurement of the temperature deep in the human tissue (no less than 5mm deep from the body surface) can more accurately reflect the core body temperature and is more meaningful for indicating human health.

[0004] In response to the above problems, after a comprehensive analysis of the research status of core temperature monitoring at home and abroad, the existing technology can classify the measurement methods into two categories. The first is the direct measurement method, that is, the temperature of a certain part of the human body is measured directly to approximately replace the core temperature of the human body. Although this method is relatively simple to operate, it has large errors and is easily affected by external factors. The second is the indirect estimation method. This method uses physiological data such as human body surface temperature and heart rate to infer the actual temperature inside the human body through modeling, calculation and analysis. This method often requires a large amount of population experimental data as a benchmark value, and it is easy to have large differences depending on the different groups of subjects being measured, and it cannot be universally applied. Summary of the invention

[0005] In order to solve the problems in the above-mentioned prior art, the present invention provides a system and method for measuring core body temperature and multimodal health parameters. The invention collects the heat flux density and body surface temperature of the human body through a thermoelectric device module, and uses the heat flux method to construct a heat transfer model of the human body to infer the core body temperature. The test error is small, which improves the measurement accuracy of the system. Secondly, the thermoelectric device module is wrapped with a thin copper sheet and an insulating plastic layer on the outside, which can overcome interference from the environment and guide the heat flow to be transferred along the thickness direction, thereby improving the anti-interference ability of the system.
