The present invention provides a combination drape and carrying bag unit including a singular sheet or plurality of joined sheet of pliable materials, both permeable and impermeable, of size to define a mat to accommodate a working medical procedural area thereon, upon which may be placed in single or combination, medical equipment and patient. The sheet has a drawstring casing extending about its periphery. The casing has openings therein on opposite sides of the mat and a drawstring is received in the drawstring casing and is of size to extend continuously about the periphery of the sheet when it defines a mat. The drawstring is slidably received in the drawstring casing so that when portions of the drawstring are pulled out of the drawstring casing through the openings, the periphery of the sheet forms gathers adjacent the casing to permit the periphery to reduce in size whereby the unit forms a carrying bag. Those portions of the drawstring which are pulled out of the casing may be secured together adjacent the openings to form a handle for the carrying bag.
