Public View

Universal Medical Device Nomenclature System™ (UMDNS) is a standard, free of charge, monthly updated, international nomenclature and computer coding system to help you better manage medical devices. UMDNS is the worldwide nomenclature that has been officially adopted by many nations.

UMDNS facilitates identifying, processing, filing, storing, retrieving, transferring, and communicating data about medical devices. The nomenclature is used in applications ranging from hospital inventory and work-order controls to national agency medical device regulatory systems and from e-commerce and procurement to medical device databases.

If you need monthly updates and access to downloadable files you need UMDNS Plus.
