Application of RFID tags in smart medicine cabinets
In the drug access link, RFID technology realizes the whole-process automatic control. After medical staff open the intelligent medicine cabinet through identity verification, the drugs with RFID UHF anti-liquid tags will be recognized in real time by the reader-writer inside the cabinet. When taking drugs, the system automatically records the drug name, specification, quantity taken and personnel information without manual entry. For liquid medications such as injections and eye drops, the label's liquid-resistant properties ensure stable data transmission even when the label is on the surface of the liquid medication, preventing information loss. After implementation at a top-tier hospital, the accuracy of medication dispensing records increased to 100%, and dispensing time was reduced by 40%.
Intelligent inventory management is another core application. The intelligent medicine cabinet regularly conducts automatic inventory of internal drugs through RFID readers. The system compares the inventory data with the preset threshold in real time, and automatically issues replenishment and expiration warnings when the drugs are below the minimum inventory or approaching the expiration date. The UHF manufacturers developed by rfid tag manufacturers support simultaneous identification of multiple tags, reducing the inventory time of the entire cabinet of drugs from the traditional 2 hours to within 10 minutes. At the same time, the unique code stored in the tag can be associated with the whole life cycle information of the drug, realizing the seamless connection between inventory data and the hospital HIS system.
In addition, RFID technology has also strengthened the drug traceability and anti-counterfeiting capabilities. The circulation track and handler of each box of drugs are synchronized to the system through the RFID tag. Once a drug quality problem occurs, the whole chain traceability can be completed within 30 seconds. The encryption technology of the tag also effectively prevents counterfeit drugs from flowing in, ensuring drug safety. These applications promote the intelligent medicine cabinet to realize "automatic access, precise inventory, and full-process traceability", and the technological innovation of UHF tag manufacturers provides continuous motivation for this change.
