A novel information retrieval method based on R-tree index for smart hospital information system

With continuous development of the internet of things (IoT) technology in various fields, it plays an increasingly important role in medical technology Smart medical care is a new medical model characterized by medical information and "medical maintenance integration"[2]. "Internet +" medical has made the diagnosis and treatment services more convenient, more efficient and smarter The core is a smart hospital information system for wise information technology, whose kernel is internet of things. IoT include sensor, body area network [4], radio frequency identification (RFID) [5], wireless communication, data processing, network, video detection and recognition and global positioning system (GPS). It's the fact that these comprehensive technologies are applied for exchanging information and communication in the whole medical administrative system, in order to implement a kind of network technology of intelligent identification, location, trace, surveillance, management. Therefore, the hospital information system established through the IoT is more real-time, accurate and efficient than the system without IoT.
