Abstract
Abstract A disposable double-clamp device for severing an umbilical cord while maintaining the severed ends thereof in a clamp. The clamps are held together in a side-by-side relation by a shear pin. A cutting blade is hingeably 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 and severs the umbilical cord.
