An umbilical cord clamp may be used to hold the cord in place when a cut is made to separate a newborn baby from the placenta.his procedure usually first involves clamping the cord. The umbilical cord clamp thus refers to the devices used to hold the cord in place when the cut is made, and the clamp may stay on for several days while the remaining cord attached to the baby dries.
The umbilical cord is coated in a substance called Wharton's jelly, which serves to strengthen the cord and protect the blood vessels inside. The maternal end of the umbilical cord is attached to the placenta, which acts as an intermediary between the umbilical cord and the mother's circulatory system. The other end attaches to the fetus in the abdominal area (what will later become a person's navel or belly button).
