Abstract
Abstract An assembly for permitting a sterile person to control adjustable equipment in a sterile field without contamination to the person or the field. The assembly includes a cover having two halves which can be folded together over the handle of the equipment in a closed position to isolate the handle from the sterile field. A flap on the cover isolates a control panel on the equipment from the sterile field. The assembly also includes a container in which the cover is sterilized and with which the cover is so applied to the handle following sterilization that the container provides a barrier against contamination of the exterior of the cover during such application. The container is structured to maintain the cover in a partially closed position and is adapted to be so deformed that the container can move the cover from the partially closed position to a closed position around the handle.
