Background Art

[0002] In clinical infusion scenarios, nurses need to monitor multiple patients at the same time and face the following problems: 1. Risk of delayed dressing change: According to statistics, the average number of patients monitored by nurses in tertiary hospitals is 15-20. Due to the large number of patients, it is difficult for nurses to monitor the infusion progress of each patient in real time. The delay rate of dressing change at the end of infusion exceeds 12%, which can easily lead to safety accidents such as blood return and air embolism (data source: "China Nursing Management" 2022 statistics); 2. Existing technical defects: Currently, there are infusion monitoring methods such as weighing method (relying on high-precision sensors, high deployment cost per bed, and susceptible to environmental vibration interference), counting method (unable to adapt to different drip rates of liquid medicine, high false alarm rate), and heating method. However, these methods usually require complex equipment deployment or deep connection with hospital information systems, high implementation costs, and difficult to popularize; In response to the above problems, the present invention proposes an intelligent management system for infusion without accompanying persons based on the Internet of Things.
