Schreiner develops RFID labels for prefilled syringes

Both companies presented newly developed prefilled syringes with RFID for the first time during the recent PDA Universe of Prefilled Syringes and Injection Devices Conference in California. Combining syringes and smart labels opens many opportunities to optimize hospital routines.

What makes the new RFID labels special is the combination of marking the syringe with its unique digital identity. This enables optimized processes in hospital inventory management, patient care and documentation, and the identification of a medication and a medical device. In addition, a digital first-opening indication to protect the integrity of the syringe is possible.  

To successfully implement this innovation and to ensure RFID functionality in terms of good performance and adequate range, various characteristics of the prefilled syringe must be considered. Aside from the material such as COC, PP, or glass, which can affect the range and reading of the tag, syringe size and diameter play a decisive role. The smaller the syringe, the less space for product marking and integration of the RFID chip. Plus, the smaller the tag, the shorter usually its read range. In addition, the curvature may affect performance, especially in the case of small syringe diameters.  

The dielectric properties of the medications in the syringe also play a role. Especially water-based active ingredients have a negative impact on the radio transmission performance of a tag. This requires precise positioning of the RFID-Label and integrated inlay according to the liquid and fill level. Additionally, specific data standards for identification and tracking on the unit level, such as UnitVisID or GS1, must be considered, enabling all relevant stakeholders to interpret and use the data and integrate it into the respective infrastructure.

Schreiner MediPharm and Schott Pharma adapt the technology to the customer’s requirements to ensure optimal functionality from production to final use. This helps enhance product safety and avoid potential medication errors.
