Laser Marking for UDI

UDI is an abbreviation of Unique Device Identification. 

Identifying medical devices helps improve safety in the medical field, including in the distribution stage. This operational system was designed to make providing the optimal treatment even easier. 

In December 2013, the International Medical Device Regulators Forum (IMDRF) the UDI Guidance document in order to ensure global consistency in adoption of the UDI system. 

At present, only the US is subject to the UDI rules, but other countries are also gradually adopting the UDI system.

Put into effect in the US in September 2013, the UDI system gradually became mandatory a year later in September 2014. Adoption of the UDI system began on the following dates in other countries where production of US-bound medical devices exists.

[Class II]

Endoscopes, X-ray diagnostic equipment, ultrasonic image diagnosis equipment

Need for direct marking

Medical instruments such as steel instruments and endoscopes are generally compact and precise. Repeated use after washing and sterilising is common, so usual display labels such as paper or film are problematic due to limited space for affixing and long-term durability. 

There are also unacceptable risks in terms of medical practices, such as the label coming off during surgery and becoming residual foreign particles within a patient’s body. 

These concerns have resulted in a growing need to establish a system that incorporates a direct marking method.

 

Need for direct marking

Advantages

Managing medical equipment through the use of direct marking carries the following advantages.

 

Quality maintenance through tracking of usage frequency

Optimisation of replacement/order timing

Improved efficiency and standardisation of instrument sets

Tracking of processes for each instrument (location management)

Reduction in excess inventory

Analysis of loss/theft

Advantages

What kind of marking is necessary?
