ABSTRACT A transparent dressing for substantially sealing a wound consisting of a semi-rigid frame for defining an opening and a resilient transparent membrane member substantially covering the opening in order to form a transparent window. The transparent material allows air and vapors to permeate the material in a first direction and prevent contaminants and fluids from enter-ing the wound area in an opposite direction. Several embodi-ments of the invention are shown for firmly holding tracheostomy tubes to the dressing. |
