It is intended for single, one-time use only and must be applied by a trained birth attendant, including physicians, nurses, midwives, or traditional birth attendants (TBAs).{{Project data\n| type = Medical Supply\n| authors = Mark Mellors\n| location = Haiti\n| status = Deployed\n| verified-by = Field Ready\n| years = 2016\n| made = Yes\n| tools = 3D Printer\n| cost = USD4.13\n}}The clamp is 3D printed using ABS plastic filament and measures approximately 6.2 cm x 4.6 cm in its open state.\n\n[[File:HL001 Image CAD.jpg|thumb|CAD Image of the Umbilical Cord Clamp]]\n\n{{Device data|design-files=https://www.appropedia.org/File:HL001_Eng_Dwg.zip|schematics=https://www.appropedia.org/File:HL001_CAD.zip|oshwa-uid=US000203}}\n\n{| class=\"wikitable\"\n! colspan=\"2\" |More Product Information\n|-\n| Author Code\n| HL001\n|-\n| Documentation License\n| CC-BY-4.0\n|-\n| Open Hardware License\n| CERN\n|-\n| OSHWA Certification\n| January 3, 2020\n|-\n| OSHWA UID\n| US000203\n|-\n| Start Date (Development)\n| April 29, 2016\n|-\n| End Date (Development)\n| April 29, 2016\n|-\n| Designer\n| Mark Mellors\n|-\n| Maker\n| Mark Mellors\n|-\n| Main Materials\n| ABS Plastic\n|}\n\n== Readiness Levels ==\n\n''Levels are identified based on this reference:'' [[Field Ready Readiness Levels]]\n\n{| class=\"wikitable\"\n!

A maker manual provides step-by-step instructions for replicating the design, including materials, tools, and assembly guidance, so that makers in different locations can build the product accurately and consistently. A user manual, where applicable, explains how to properly set up, use, and maintain the product once it is built, helping ensure it performs safely and as intended for the end user. Together, these manuals make the design accessible to both fabricators and the people who ultimately rely on the product.\n}}{{Page data\n| part-of = Global Field Ready Portfolio\n| keywords = Medical Spare Part\n| sdg = SDG03 Good health and well-being\n| authors = Charles Vincent Barrete\n| organizations = Field Ready\n| license = CC-BY-SA-4.0\n}}"}
