A probe and method for non-invasive human body core temperature detection

Abstract

The invention provides a non-invasive human body core temperature detection probe and method, including a probe heat conduction layer, at least three heat transfer units with different heights and a control unit; by setting the heat transfer unit and heater, according to the heating treatment, the establishment of thermal balance is accelerated, Improve the rapidity of human body core temperature detection; improve the ability of the detection device to resist environmental factors by using an adaptive filter based on the minimum gradient algorithm; through the combined compensation of at least three heat transfer units in the human body core temperature detection probe due to the uneven lateral heat flow of the human body The measurement error caused by uniformity improves the detection accuracy.

Description

technical field [0001] The invention belongs to the field of medical physiological signal detection instruments and equipment, in particular to a non-invasive human 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 medical process, it is sometimes necessary to monitor the temperature change for a long time to reflect the physical health of the person. Body temperature includes body surface temperature and human core temperature. Among them, the core temperature of the human body 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 temperature detection needs to...

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
