The system uses vital sign monitoring system management software and IoT data engine as software platforms, and wireless intelligent mattresses and temperature tags as hardware platforms,Relying on advanced technology The Ocamar OneNet Unlimited® medical dedicated wireless IoT platform. Through wireless intelligent mattresses, patients' pressure ulcers, heart rate, respiratory rate, body movement, turning over, and out of bed data can be dynamically and continuously collected, analyzed, and statistically analyzed. Connected to the platform through the Internet of Things, the platform will standardize and convert the received physical sign data, achieving bed monitoring and real-time alarm reminders for abnormal events. To achieve the purpose of monitoring in bed, analysis reports and other automatic insertion into nursing records provide new data support for teaching and research in clinical departments.

Combined with the hospital's nursing system, continuous monitoring and analysis of patient signs, turnover, and other conditions are conducted to comprehensively assess the risk of pressure ulcers, and provide data on pressure ulcer related nursing performance and sensitive indicators; Keep track of the patient's physical signs and out of bed status at all times to reduce the workload of night rounds. Remind nurses to assist high-risk pressure ulcer patients in turning over based on the level of pressure ulcer risk; Record patients at risk of pressure ulcers or pressure ulcers through physical activity monitoring; Automatically remind nurses to take pressure ulcer measures and evaluate pressure ulcers. Reducing the workload of nurses, improving the hospitalization experience of patients in the hospital, and enhancing the modern standards of intelligent nursing in the hospital are indispensable parts of modern clinical nursing.

· Automatic collection of intelligent mattresses, non-contact collection of vital sign data such as patient breathing and heart rate;

· Multiple standard interface docking methods, including directly controlled I/O ports, low-power Internet of Things interfaces, standard USB interfaces, and Bluetooth interfaces, enable rapid data collection by sign collection devices;

· Automatically prompt for pressure ulcer risk and remind nurses to proactively handle pressure ulcer risk assessment.
