Abstract: A disposable drape for use in covering dual-tier surgical carts used in hospital operating rooms. The drape is adapted to be placed upon both shelves of a surgical or medical cart having two shelves—an auxiliary shelf situated above a larger main shelf or table. The drape is intended to be sterile, and is provided with absorbent surfaces at locations corresponding to the tup surfaces of the cart's shelves when the drape is properly installed upon the cart. The drape is seamless. Pull tabes are provided to aid in the installation of the drape upon a cart without compromising drape sterility.

Abstract: An auxiliary shelf that can be attached to existing operating room carts to provide additional sterile space upon which instruments may be placed for access during surgery. The auxiliary shelf is located above the main shelf area of the cart. The auxiliary shelf can be swivelled between a collapsed position parallel against the back of the cart when not in use to permit storage of the cart in less space. The vertical position of the shelf can be adjusted, and a lift assist is provided to reduce the effort required to raise the auxiliary shelf from the lower collapsed storage position to the horizontal use position above the main shelf of the cart. There also is provided special custom drape for placement upon the auxiliary shelf to provide a sterile covering for the auxiliary shelf. The drape includes several special features which permit it to be handled, placed upon the auxiliary shelf, and secured in place with minimal challenges to sterility and to maintain the sterile filed in the operating room.
