Description

technical field [0001] The invention belongs to the field of medical physiological signal detection instruments and equipment, and in particular relates to a non-invasive human body core temperature detection probe and method. Background technique [0002] With the development of the times and the advancement of technology, the field of medical devices has also made great progress. In the course of medical treatment, it is sometimes necessary to monitor the change of body temperature for a long time to reflect the health status of a person. Body temperature includes body surface temperature and human body core temperature. Among them, human body core temperature can more accurately reflect the health status of the human body, and is more concerned by medical staff. [0003] According to whether it is invasive to the human body, the detection methods of the core temperature of the human body can be divided into invasive detection and non-invasive detection. Invasive core te...

Problems solved by technology

[0006] The advantage of this measurement device is that it can realize non-invasive detection of the core temperature of the human body, and eliminates the influence of different thermal resistances of different measurement objects on the measurement results. It completely relies on the heat conduction of human body temperature to achieve it. It takes a long time to obtain the temperature of the human body, and it takes more than 20 minutes to obtain a more accurate temperature of the human body; secondly, the anti-interference ability of the device is poor. When the law changes, the original thermal stability of the heat transfer unit will be broken, resulting in a decrease in the accuracy of the core temperature measurement of the human body; in addition, when detecting a curved surface such as the forehead of the human body, only two heat transfer units cannot overcome the horizontal temperature of the human body. The influence of uneven heat flow on detection leads to increased detection error
