Abstracts: The current non-contact measurement tools used in body temperature detection are mainly infrared thermometers, which are safe, convenient to use, rapid detection, no cross-infection, won the favor of clinical medical staff, security personnel for temperature monitoring in public places and families, etc. Infrared thermometer is easily affected by environmental factors, how to improve the measurement accuracy of infrared thermometer has become the main direction of infrared thermometer research and development. In this paper, the status of patent applications for infrared body temperature detection was statistically analyzed, and the main patent technologies for infrared body temperature detection were studied.
Keywords: infrared temperature detection;thermal effect;photoelectric effect;patent technology application
當前,常用的体温计主要有水银体温计、电子体温计、红外体温计和红外热成像仪[1]等。体温检测的部位主要有人体腋窝、耳内、前额、手腕、口腔、手心、直肠等处。水银体温计具有示值准确、稳定性高、价格低廉的优点,但也存在易碎、读数不直观的缺点;电子体温计具有安全经济、温度波动小、读数方便准确、携带方便的优点,但也存在易受电子元件及供电等因素影响,稳定性不高的缺点;红外体温计和红外热成像仪具有采集体温简单、方便、快捷、无须直接接触使用等优点,但也易受环境温度影响[2]。红外体温检测为非接触式地实现对人体温度的测量,应用广泛,因此,对红外体温检测专利技术进行研究,以提高当前红外体温检测设备的稳定性和精度是十分必要的。
