Technical Field

The invention belongs to the technical field of medical electronics, and particularly relates to a rapid brain core temperature measuring instrument.

Background

In combination with the reports at home and abroad and the knowledge of the people in practice, the monitoring of the core body temperature is considered to be an important means for early judging the heat shooting disease (serious heatstroke) and other febrile diseases, although the existing body temperature detection modes are various, the existing body temperature detection modes have different standards, the detection parts of the peripheral body temperature such as axillary temperature, forehead temperature and the like are extremely unstable and have a larger difference with the core body temperature of a human body, and the novel body temperature measurement mode also has the limitation, such as a convenient and quick tympanic membrane infrared ray temperature measuring instrument and a temporal artery temperature measuring instrument, which are also found to have small correlation with the rectal temperature in the heat shooting disease body temperature detection. Rectal temperature is still the recommended site for measurement for the internationally recommended heat stroke. The thermometer which can measure the rectal temperature at present is inconvenient to use, the applied mercury thermometer takes long time (needs 3-5min) for measurement, and the mercury thermometer cannot be kept in the rectum of a patient for a long time due to the possibility of rectal perforation. Therefore, medical staff mostly detect the body surface temperature, which may cause missed diagnosis or delayed diagnosis of some febrile cases, and cause the patients to miss the best diagnosis and treatment opportunity, thereby increasing the difficulty of subsequent treatment, especially for the heat-shooting disease, the disability rate and the fatality rate of the heat-shooting disease are increased without active early treatment. Theoretically, the ideal human body core temperature measurement site is in the brain, but the measurement of the brain core temperature using the invasive direct contact method is difficult to realize. We find that the zero heat flow temperature detection method can realize the detection of the core temperature of the brain at the forehead, and based on the zero heat flow principle, a circuit system for detecting the core temperature can be designed by adopting a constant current source method so as to realize the portable and rapid measurement of the core temperature.

Therefore, the invention provides a rapid brain core temperature measuring instrument.
