ECRI Institute disseminates its Universal Medical Device Nomenclature System™ (UMDNS) as broadly as possible in support of worldwide needs to improve the technology base for healthcare. At the same time, ECRI Institute must protect the organization and consistency of UMDNS to ensure that we can meet the needs of all UMDNS users, regardless of nation or language.

This agreement sets forth ECRI Institute's policy for use of UMDNS. You are responsible for complying with this policy.

What is UMDNS?

ECRI Institute's UMDNS is an international medical device naming and coding system used in thousands of institutions worldwide. It has been translated into many languages. The U.S. National Library of Medicine incorporates UMDNS into its Unified Medical Language System (UMLS). National medical device regulatory agencies employ UMDNS to organize their information systems. Large device-related databases and many publications use UMDNS for indexing and retrieving information. Thousands of hospitals and other organizations employ UMDNS to organize their equipment inventories in conjunction with the appropriate management systems and software.

UMDNS consists of a unique five-digit universal medical device code (UMDC) number followed by a plain-language description in English or other languages. The key to system consistency and integrity is the precise correlation of code numbers with the specific physical entity. Use these numbers to establish document files and computer-based data retrieval systems, and to index articles, hazard publications, recall reports, regulatory data sets, etc. UMDNS terms are also used in more detailed product classifications.

UMDNS is available as downloadable ASCII and Microsoft Excel files. To obtain a user ID and password for UMDNS, you must first complete a registration form. ECRI Institute will send you an ID and password that is valid through December 31, 2018.
