Abstract
Description
Technical Field
[0001] This utility model belongs to the field of consumable inventory technology, and relates to a consumable inventory device, and more particularly to a medical consumable inventory device based on RFID identification technology. Background Technology
[0002] RFID technology, as an emerging automatic identification technology, has significant advantages such as non-contact operation, long-distance reading, batch identification capability, and large information storage capacity. Currently, many medical consumables have RFID tags affixed to their packaging before entering hospital departments for acceptance, aiming to achieve efficient and accurate management through this technology.
[0003] However, the general-purpose reading devices currently widely used in hospitals, which are based on infrared identification technology, cannot fully leverage the advantages of RFID technology when faced with RFID tags, and have the following drawbacks: Infrared reading has poor stability. Medical environment conditions are complex and changeable. Strong light in the operating room, electromagnetic interference from instruments, and obstructions caused by personnel movement can all interfere with the accuracy of infrared scanning and easily lead to incomplete data entry. Medical consumables vary in size, shape, and material, and have different requirements for the attachment position and recognition angle of the label. Infrared devices cannot achieve effective recognition from all directions without blind spots. Infrared recognition can only read one tag at a time, and the data reading speed is relatively low, which increases the workload of medical workers in managing consumables to some extent.
[0004] During the data integration process of medical consumables management systems, the data transmission security of infrared devices is weak. Simple encryption methods, or even unencrypted data transmission, are insufficient to meet the stringent data security requirements of medical information systems. Using infrared scanning for medical consumables management also faces bottlenecks in terms of speed and accuracy, increasing the workload of medical staff.
