UDI marking

Unique Device Identification (UDI) made easy

With the complete turnkey package from TRUMPF you can mark medical devices permanently and reliably using lasers and software from a single source. Medical technology products and devices now need to bear a unique device identification code, or UDI, that is legible across the entire supply chain. The most important requirement is for markings to be permanently legible, something that is frequently achievable only with laser marking.

What does Unique Device Identification (UDI) mean?

Unique Device Identification (UDI) refers to a global standard system for identification in medical products. A UDI marking consists of two parts – a machine-readable code and a human-readable code. The machine-readable part is represented either as a linear barcode or as a 2D Data Matrix Code, and the human-readable part with numbers and letters.

What is the purpose of the UDI system and what requires marking?

Patient safety is the top priority in medical technology. Clear and consistent medical-device labeling is fundamental to this - from manufacturers to retailers and from hospitals to the patient. This maintains full transparency along the supply chain. Unique Device Identification enables those responsible for procurement and materials management to access regulatory specifications held in central databases. Serial numbers and expiration dates are examples of this. When a medical device is marked "UDI-compliant", no further details are required. In the foreseeable future, all medical devices in any risk class will require clear and machine-readable labeling.

Do all medical devices require UDI marking?

All medical devices intended for sale in the United States or on the European market must have a UDI code. The goal is clear: a globally standardized UDI system. The medical technology industry in every market is being advised to label their products with UDI codes in anticipation of new legal requirements.

Which standards exist for UDI labeling?

UDI labeling of medical devices is based on specific standards. To this end, the US Food and Drug Administration (FDA) has accredited three organizations as UDI issuing agencies: GS1, Health Industry Business Communications Council (HIBCC), and the International Council for Commonality in Blood Banking Automation (ICCBBA). Generally labels always consist of two parts: the "DI" (Device Identifier) and the "PI" (Production Identifier). The DI, which is identical for each item, includes the ID of the manufacturer or labeler as well as the reference code of the product. In contrast, the PI is dynamic, containing information such as expiration and manufacturing dates and serial numbers. The global data exchange network Global Unique Device Identification Database (GUDID) enables manufacturers to forward product information to the American FDA UDI database.

Which UDI regulations exist within the EU?

In contrast to the US FDA regulation, the EU introduced a new identifier based on the European Union Medical Device Regulation (EU MDR) – "Basic UDI-DI". This enables medical devices with similar characteristics to be grouped in the EU approval database EUDAMED. The device can only be submitted to the authorities responsible for approval after the medical device manufacturer or an authorized representative has allocated the new identifier.

Where can I find out more about current deadlines and regulations on UDI-compliant marking of medical products?

All information on US regulations is available on the website of the US authority, the US FDA.

All key European regulations are summarized on the EU MDR website.

Equipped for the future

Ensure operational readiness for UDI compliance in 2020 and beyond with passivation resistant laser marking solutions.

Automated

With a database connection, send sequenced UDI device identification (DI) and production identifiers (PIs) to the TruTops Mark software to automatically populate a recognized UDI barcode readable throughout the device’s intended lifetime.

Process reliability

With our VisionLine Mark image processing, you can easily recognize, capture and verify UDI content.

Efficient

Verify the laser marked content and apply a customized grading for quality assurance to reduce time to clearance.

Certified

TRUMPF is a recognized GS1 Solution Partner. GS1 is one of four authorities which develops and awards UDI codes as per accredited standards in order to guarantee the traceability of medical products.

1. Access to database

The software is linked to databases. Reading information into the system via external hand scanners is also possible.

2. Production data input

Data is available from the database or read out using a hand-held scanner.

3. Create UDI code

The UDI module creates a UDI-compliant code with relevant data and individual production extensions.

4. Component and position recognition

The image processing programs VisionLine Detect or VisionLine Model detect the component and its exact location and position. The software forwards the information to the controller which makes the marking in the precise position.

5. Marking laser

The TRUMPF laser marks the workpiece with a durable, corrosion-resistant and high-contrast marking that remains machine-readable and visible to the human eye even after numerous cleaning cycles.

6. Optional code content capture

Subsequent quality control is also very easy with TRUMPF process sensors. With the TRUMPF image processing solution, VisionLine, UDI-compliant codes can be recognized, read out and evaluated for quality using various methods.

7. Optional marking data check

Using the image processing programs VisionLine OCT (for character recognition) or VisionLine Code (for 1D/2D codes), marked data can be compared against the database and stored for documentation purposes with additional information if desired.   This includes information on UDI code content and quality, or on the machines involved in the process. This ensures proper documentation of the component and marking even after many years.
