E Z CLAMP is ready to use immediately. the user simply presses and closes the clamp (exactly as done with the regular Umbilical Cord Clamp), the clamp will close and cut the cord, then it will automatically separate into two parts - one will be the regular Umbilical Cord Clamp that will stay with the baby and the second part will be attached to the placenta. The E Z Clamp is composed of two regular Umbilical Cord Clamps and a Stainless Steel Knife that is combined together into one instrument which looks, feels and operates as a regular Umbilical Cord Clamp. The E Z Clamp will separate after use into two or three parts - one will be a regular Umbilical Cord Clamp, and the second part with the knife will clamp the placenta. Please look at the inside of the white clips. You can notice the spatial unique design. A sticking out bulge on one side and the opposite side has depression (female and male). This insures that after the closing, the female and male will go in one another and make cretin for good holding of cord.
