Abstract: Focusing on the requirements of visual traceability for reprocessing of reused medical devices under the background of deep integration of intelligent medical treatment, a quality and safety traceability system for disinfection of reused medical devices is developed. The multi-dimensional data of the reprocessing chain of reusable medical devices are acquired in real time by the RFID mobile terminal handset and stored temporarily. The data package is formatted based on LoRa protocol and uploaded to the management and control platform in multi-threaded transmission mode for in-depth analysis and traceability. The corresponding prototype system is developed. The first-line operation and maintenance test results show that the prototype system has strong cooperation, strong operation robustness, and obvious advantages in the identification rate and other layers of sterile equipment package.
