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 entering the wound area in an opposite direction. Several embodiments of the invention are shown for firmly holding tracheostomy tubes to the dressing.
