Description

Technical Field

[0001] The utility model relates to the technical field of body temperature detection instruments, in particular to an ear canal temperature measuring probe. Background Art

[0002] The core body temperature detection technology of the human body is not mature yet. The existing detection methods will be slow to respond, have reduced accuracy, and be susceptible to interference when dealing with large-scale changes in human body temperature, changes in ambient temperature, and human activities. In response to the above problems, researchers found that no matter what detection method is used, a relatively closed detection environment is more conducive to accurate data reading, and the ear canal is an ideal temperature measurement site that meets the conditions of human movement.

[0003] Studies on ear canal temperature measurement have shown that the bottom of the ear canal is deep in the brain and close to the hypothalamus, and has a rich blood supply around it, so the temperature of the eardrum is approximately the core body temperature of the human body. However, the structure of the ear canal varies from person to person, with different lengths and apertures. There is also a temperature gradient directly from the eardrum to the external auditory canal, and the temperature gradient is related to the structure and length of the ear canal. This makes it difficult to measure the temperature in the ear canal, so an ear canal temperature measurement device that can effectively detect the ear canal temperature to support the calculation of the eardrum temperature is a product that is urgently needed on the market.
