Communication between Medication and Medical Device

The Lock-and-Key Principle

The lock-and-key principle refers to two components that have to be precisely matched in order to start a process or enable the use of a product following a digital exchange of information. In the pharmaceutical industry and medical device technology, the lock (an RFID reader) is installed in a medical or laboratory device while a consumable equipped with an RFID_Label—such as a medication, sample or reagent container—holds the matching key.

The key may be invisibly embedded and is read in the background in a contactless and fully automatic process. The reader controls the mutual communication: For the delivery of a medication, the medical device reads the data stored on the RFID chip, such as the product code and dosage, and initially checks the drug’s expiration date and authenticity. This information is utilized to configure the device and stored for subsequent deliveries of the medication, which are then controlled by the device using the information transmitted by the chip.

In addition to “classic” RFID chips, Schreiner MediPharm offers flexible chips by PragmatIC as a particularly cost-effective means of consumables identification. The flexibility of the chips additionally enables easy application to particularly small bending radii.

Possible Uses

Medical devices:

  • Blood pumps
  • Infusion pumps
  • Insulin pumps
  • Pens
  • Adherence aids
  • Laboratory equipment
  • Diagnostic devices

Consumables:

  • Pens
  • Autoinjectors
  • Vials
  • Syringes
  • Carpoules
  • Plastic components

Benefits

  • Enhances patient safety during administration of medicines and self-medication
  • Prevents use of expired, wrong or falsified medicines or consumables
  • Helps avoid errors in medication use or dosing
  • Prevents reuse and misuse of original containers

Interaction between patient and device

The Swiss company Ypsomed has designed the SmartPilot™—an electronic add-on for the UnoPen™ and the YpsoMate® autoinjector—as an innovative means of assisting patients. An NFC-Label from Schreiner MediPharm applied to the injection aid serves as the communication interface. It connects the SmartPilot™ with the pen or autoinjector and thus turns it into a smart tool for self-medication.

Low-Cost RFID

With label-integrated RFID technology, products or medicines can be clearly identified, traced and authenticated according to the lock-and-key principle. However, conventional RFID/NFC solutions have mainly been adopted in high-value use cases.

In order to be able to offer smart Pharma-Labels also for low-cost medicines and high-volume requirements, Schreiner MediPharm entered into a strategic partnership with PragmatIC, a world leader in low-cost flexible electronics.
