Abstract
A surgical dressing comprises a slab or strip of open-cell synthetic foam material sandwiched between layers of gauze. The foam slab provides good absorption capacity and homogeneity to the dressing while reducing adherence to dried wounds. The foam slab also adds some rigidity to a strip of dressing which can then be used to form compressing and stabilizing bandages.

A surgical dressing for protecting a wound and immobilizing a body joint during healing which comprises a pad including:
- a top sheet of surgical gauze;
- a bottom sheet of surgical gauze;
- an intermediary slab of open-cell synthetic foam material said slab having substantially flat and parallel top and bottom surfaces in contact with said top and bottom sheets respectively;
- means for holding said sheets and slab in a layered configuration;
- said pad having a rigidity sufficient for immobilizing said body joint when said pad is wrapped around said joint;
- wherein said sheets and slab are substantially commensurate;
- wherein said slab comprises a length of said foam material having a given, substantially uniform width;
- and
- which further comprises a strip of surgical gauze having a width substantially double said given width, said strip being transversally wrapped over said length of foam to form said top and bottom sheets.
