Abstract: This research is based on data from clinical information systems such as HIS, EMR, LIS, etc, based on the functions of the traditional paper bedside card, relying on wired network technology, using the Internet of Things technology to design and develop a multi-functional intelligent interactive electronic bedside card system for inpatients. The functional framework of the system is introduced and discussed in detail, and the design is carried out from several aspects of system architecture, network architecture, software architecture, database and software system. The results show that the system has stable performance and can ensure the real-time and accuracy of medical information. The implementation of the system can fully meet the needs of clinical first-line ward management, reduce the workload of nursing staff, improve work efficiency, and reduce the possibility of medical accidents. At the same time, it can facilitate patients to see their own health information, improve patient experience. It has important guiding significance for the development of ward management and hospital information construction.
