Safe Supply Chain in Hospitals with RFID

Safe and efficient medicine management!

Whether in warehouse management or during the preparation of medicine trays: The fast-paced activities in daily hospital settings require efficient, error-free medicine management. RFID labels provide a viable solution for this purpose.

However, on syringes or vials containing liquid medications, reading of UHF RFID labels positioned close to the liquid is impaired. That is why flag labels protruding from the container are frequently used. In many cases, they can be reliably read but usually have to be applied to the container manually at the hospital, which is very time-consuming.

The new RFID label solutions from Schreiner MediPharm solve this problem: They are suitable for fully automatic processing and minimize the negative effect of liquids.

The main challenge with UHF RFID labels specifically for syringes and vials with liquid medications lies in reliable reading of the chip, because both the container material and the composition of the liquid may negatively affect readability. Flag labels by and large circumvent this problem.

However, the disadvantage of these solutions is that the protruding RFID labels may tear, require additional space, and entail inconvenient handling and cost-intensive manual application. Especially for syringes and vials, Schreiner MediPharm has designed two new, very robust label constructions.

In both cases, the antenna is largely located outside of the area filled with liquid, which allows for a longer read range. The label-integrated RFID inlay is located in the area of the cap and can be automatically processed during the normal labeling process of the primary container. In addition, both RFID solutions simplify bulk reading and can optionally be complemented by digital first-opening indication.

Cap-Lock for Syringes

The Cap-Lock cap adapter is placed on top of the primary closure of the syringe and interlinked with it in order to equalize the differing radii of the syringe body and closure. The label wraps around the syringe body and the cap adapter for tamper evidence. The RFID inlay adapted to the application is integrated in the upper part of the label at the level of the cap.

Flexi-Cap for Vials

Flexi-Cap combines a marking label and a film cap for irreversible first-opening indication and ensures the integrity of the vial. Complemented by an RFID inlay at the level of the cap, it turns into an identification tool for each individual container.

Using simple handheld or special readers, the data stored on the RFID labels—such as product name, manufacturer, batch number and expiration date—can be automatically read and synchronized with a database.

This enables accurate tracking of the inventory and provides transparency about medicines that may be lacking or should be used soon. Thus, patients are protected against possible medication errors and potential misuse of critical medicines by healthcare staff is prevented.
