Background

Clinically, the body temperature is an average temperature in a deep part of a human body, i.e., a central temperature, and is relatively stable and uniform. As the temperature in the center of the body is not easy to measure, in clinical diagnosis and treatment, the mercury thermometer is generally used for measuring the temperature of armpits, sublingual parts and other parts of the human body so as to realize body temperature measurement. Under the influence of various factors such as blood vessel distribution of a temperature measurement part, operation proficiency of a temperature measurer, cooperation of the temperature measurer and the like, the sublingual temperature measurement accuracy is generally considered to be superior to armpit temperature measurement. Compared with the sublingual oral cavity, the deep oral cavity blood vessels are densely distributed and are not easily influenced by external cold and hot air, so that the deep oral cavity temperature changes little, the temperature distribution is uniform, the body temperature of a human body can be accurately reflected, meanwhile, the effective area of the temperature measurement in the oral cavity is large, the measurement is convenient, and the oral cavity deep region is selected as a target point for measuring the body temperature, so that the sublingual oral cavity deep blood vessels have the advantages of convenience, accuracy, effectiveness and the like. In addition to the central temperature, the body also has a body surface temperature, i.e., the temperature of the outermost skin surface of the body. Generally, the body surface temperature is lower than the central temperature, obvious temperature gradients exist in the interior and the surface, large temperature differences exist in the body surface temperatures of different parts, the head is the highest, the limbs are the lowest, and the body surface temperature is easily influenced by multiple factors such as environmental temperature, individual difference, day and night change, age, muscle activity, mental factors, food intake and the like.

The non-contact temperature measurement method commonly used in the market is an infrared body surface temperature measurement method, the body surface is selected as a temperature measurement area, the temperature measurement principle is that the body surface temperature of an individual is measured and then converted into the actual body temperature, and the body surface temperature is susceptible to various factors, so that the measurement precision far cannot meet the requirement of clinical temperature measurement precision, and the method cannot be used in related fields such as clinical diagnosis and treatment. According to the literature data, the existing non-contact infrared oral cavity temperature measurement technology has the defects that the measurement precision cannot meet the clinical temperature measurement requirement due to large errors caused by the measurement of infrared radiation drift, and the technology cannot be used in the related fields of clinical diagnosis and treatment and the like.
