### Internet of Things and Medical Management  
The term Internet of Things (IoT) was first proposed by [PERSON] in a speech in 1999 when the communication technology only included RFID communication technology, and the ITU (International Telecommunication Union) report on the Internet of Things [1] mentioned that the Internet of Things technology should not be limited to RFID, but should also be able to apply other communication technologies as the basis of the Internet of Things. The initial definition of the Internet of Things is that all objects in IoT must be defined by a standard protocol to define their global network address. Since then, IoT has started to flourish in various fields, among which the medical care and healthcare field is a very popular field. In this field, the main purpose is to enhance the service quality and efficiency of medical care and healthcare through the application of IoT technology and to accelerate the development of knowledge [7; 27].  
Nowadays, the most frequently proposed application in the management of medical institutions is to connect medical devices through IoT technology to collect various physiological data. For example, [PERSON] et al. [9] proposed the use of IoT technology to observe patients' intravenous injections. [PERSON] et al. [8] and [PERSON] et al. [4] used IoT to monitor patients' ECG and send this information to physicians for condition analysis in real time. These researches are all conducted through IoT technology to collect the physiological data of hospital patients and send the information to healthcare workers so that healthcare workers can monitor the real-time condition of patients in charge at any time and anywhere. In addition, IoT technology can also be applied to equipment resource management; for example, [PERSON] et al. [12] proposed the use of IoT technology to manage the number and location of emergency medical equipment so that the relevant equipment can be prepared as quickly as possible in case of medical emergencies. [PERSON] et al. [28] proposed installing sensing devices on medical equipment, observing the operation of the equipment through IoT technology, and predicting the remaining life of the equipment by the collected data.  
At present, Internet of Things technology has been gradually applied in medical institutions, as it is the collection of physiological information or the management of resources, and it can greatly reduce the burden of medical staff and alleviate their work pressure. However, in medical institutions, with the diversification of IoT application technologies, such as the collection format of patient physiological information and the positioning information of medical equipment, the data format of this information may be different; therefore, healthcare workers may need to constantly switch between different platforms for information exchange and use. Therefore, this study intends to integrate various information formats in medical institutions into one platform so that healthcare workers can be more consistent and convenient in integrating and exchanging information.
