The Umbilical Cord Clamp is a 3D printed device designed to enclose and clamp a newborn's umbilical cord stump, helping prevent sepsis (infection) during the neonatal period. 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).

The clamp is 3D printed using ABS plastic filament and measures approximately 6.2 cm x 4.6 cm in its open state.

About the manuals

Field Ready develops manuals to support both the fabrication and safe use of its products. 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.
