## Abstract

A multi-element surgical drape includes a bottom sheet that is placed over a patient and a top sheet that is reversibly secured to the bottom sheet. The two sheets each have a fenestration, and the fenestrations are aligned to provide access to the surgical site. After the surgical procedure has been completed the two sheets are separated. The top sheet is contaminated ("red-bag") medical waste, while the bottom sheet can be disposed of as non-contaminated waste, recycled, or processed for reuse. The invention permits a substantial reduction in the volume of red-bag waste generated by surgery.

## Claims

### Claim 1

A multi-element surgical drape, comprising
a) a bottom sheet for placement over a patient and comprising
i) a bottom surface for contacting the patient,
ii) a top surface for facing away from the patient after placement,
iii) attachment receptor means on the top surface, and
iv) a fenestration;
b) a top sheet comprising
i) a bottom surface facing the bottom sheet and a top surface facing away from the bottom sheet,
ii) attachment means on the bottom surface that attach to the receptor means on the bottom sheet to removably secure the top sheet to the bottom sheet, and
iii) a fenestration smaller than, and aligned with, the fenestration in the bottom sheet; and
c) a pouch on the top surface of the top sheet, near the fenestration, for collecting fluid runoff during surgery, the pouch comprising
i) a top edge and bottom edge joined by two opposing side edges, the side edges and bottom edge being sealed closed,
ii) means for detachably sealing the top edge to permit opening the pouch to receive fluid and then closing the pouch to prevent leakage of the fluid.

### Claim 2 (depends on 1)

The surgical drape of claim 1 in which the bottom sheet comprises a polyethylene nonwoven fabric.

### Claim 3 (depends on 1)

The surgical drape of claim 1 in which the attachment means is a releasable adhesive and the attachment receptor means is a release layer that contacts the adhesive and facilitates separation of the sheets.

### Claim 4 (depends on 1)

The surgical drape of claim 1 in which the attachment receptor means and attachment means in combination form a hook-and-loop fastener system.

### Claim 5 (depends on 1)

The surgical drape of claim 1 in which the bottom sheet further comprises guide means to indicate a preselected position on the top surface and the top sheet is placed in the preselected position.

### Claim 6 (depends on 1)

The surgical drape of claim 1 in which the top edge of the pouch has a flexible surface that may be pressed against a facing surface and the means for detachably sealing comprises a raised ridge on one surface for sealingly engaging a corresponding channel on the other surface.

### Claim 7 (depends on 1)

The surgical drape of claim 1 in which the pouch further comprises a sealable drainage port through which fluid may be drained from the pouch.
