With the extension of life expectancy, the decline of birth rate and people's concern for health, people in modern society need a better medical system. In this way, telemedicine and electronic health (e-health) are very urgent. With the help of Internet of Things/cloud computing technology, expert system of artificial intelligence, and intelligent equipment of embedded system, we will build a perfect medical system of Internet of Things, so that all people can enjoy top-level medical services equally, and solve or reduce the phenomenon of difficulty in seeing a doctor, tense doctor-patient relationship and frequent accidents caused by insufficient medical resources.
As early as 2004, the Internet of Things technology was applied to the medical industry. At that time, the US Food and Drug Administration (FDA) took a lot of practical actions to promote the implementation and popularization of RFID, and relevant government agencies passed legislation to regulate the application of RFID technology in drug transportation, sales, anti-counterfeiting and tracking systems. American hospitals adopt a newborn management system based on RFID technology, and use RFID tags and readers to ensure the safety of newborns and pediatric patients. At the end of 2008, IBM put forward the concept of "smart medical care", and envisaged that the Internet of Things technology would be fully applied to the medical field to realize medical information interconnection, clinical innovation, diagnostic science and public health prevention.
