To help the hospital expand its digitalization plan, the label and cap safety concept for pre-filled syringes now also implements automatic inventory and supply chain management, as well as digital first opening instructions. In the process, the new Cap-Lock plus RFID solution provides efficient and reliable product certification and enhanced patient safety.

Injecting syringes of liquid medicines containing RFID tags is a challenge because both the container material and the composition of the liquid may impair the reading of UHF RFID tags. Logo labels protruding from the container are often used for this purpose. However, these usually require extra space, are easily torn off, and must be applied manually.

The Cap-Lock plus RFID chip is integrated in the tag. The cap lock is a combination of cap adapter and label. The adapter is placed on the top of the main closing of the syringe and connected to each other to balance the difference in diameter between the main body of the syringe and the closing. The label is wrapped around the syringe body and the needle cap adapter. Once opened, due to the overall perforation, it can provide irreversible tampering evidence.

The RFID inlay is located at the upper end of the tag, so it is mainly located outside the liquid-filled area, allowing reliable remote reading. Due to the function of RFID, in addition to the purely visual first opening signs provided by the previously destroyed tags, digital first opening evidence is now possible. RFID tags can be automatically processed as part of the normal labeling workflow of the main container.

In automated inventory and supply chain management, in order to monitor and control the logistics process of materials and products in real time, data on syringes with RFID tags can be automatically obtained at various sites. As the selected and placed products are read, the current inventory information is consistently stored in the database. In addition, the integrity of the container, the first opening or tampering can all be digitally monitored through specially developed RFID tags.

In drug management, data stored on RFID tags (such as product name, manufacturer, batch number, and expiration date) can be read individually, or in batches using a simple handheld or dedicated reader, and matched with the database. This enables accurate tracking of inventory and provides transparency for medicines that are missing or close to their expiration dates. This helps protect patients from potential medication errors.
