Abstract
Abstract To prevent contact with the wound, a semi-rigid cylindrical hollow open-ended collar is mounted to an adhesive label by a flexible sheet. The sheet is sealed to the periphery of the lower end of the collar and ring-welded or adhesively attached to the surface of the label. The periphery of the sheet has an outwardly extending accordion-like section which expands to permit the label to accommodate the contours of the body. Irrigation ports may be situated in the collar wall. A drain port may be situated in the flexible sheet. The upper open end of the collar is designed to receive a removable cover which may have a transparent portion. Alternatively, the cover member may be provided with a flexible section surrounding an opening adapted to receive a catheter.
