Abstract
Abstract A disposable double-clamp device for severing an umbilical cord while maintaining the severed ends thereof in a clamp. Two clamps are held together in a side-by-side relation by a shear pin. A cutting blade is located between the abutting clamps, its forward cutting motion being impeded by said shear pin. After the device is brought into a clamped position, further pressure is exerted upon the blade, which breaks the shear pin. A wedge on the blade provides outward lateral pressure to the two clamps, thereby stretching the umbilical conduit at the end of the cut as well as provide for clamp separation. The blade's cutting edge then easily cuts and severs the umbilical cord. Further downward pressure causes the wedge to separate both clamps, with the ends of each portion of the severed cord being clamped by one of the pair of clamps.
