Sterility maintenance cover and instrument support

A device for maintaining the sterility of a patient and supporting medical instruments during both invasive and non-invasive procedures, which device includes a generally L-shaped member having a base panel for fitting beneath a patient and a supporting surface such as an operating table, an upward-standing side or end panel extending from the base panel and provided with an open window for accessing the patient and a horizontally-oriented instrument platform extending from the end panel parallel to the base panel above the patient's head, neck and shoulders, for receiving and deploying a drape and/or instruments during surgery. Gussets may extend from each edge of the base panel along the end panel to the instrument platform to strengthen the instrument platform. The device facilitates draping of the patient's head and upper body to insure a sterile operating field which is maintained throughout the procedure and the instrument platform facilitates deployment of surgical and other instruments in an efficient manner. In a preferred embodiment, the instrument panel, end panel and base panel are constructed of a single piece of transparent, radiolucent material such as ABS plastic.
