Attorney, Agent or FirmInternational ClassH61L 015/00AbstractA transparent bandage 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 is such that air and vapors can permeate the material in a first direction and contaminants and fluids are prevented from entering the wound area from an opposite direction. A flap can be secured to the frame such that a user cannot see any of the wound covered by the transparent material when the flap is closed. Several embodiments of the invention are shown consisting of different shapes for different medical needs. A third and fourth embodiment are included for holding tracheal or other types of tubes to a patient such that the area around which the tube is inserted can be readily observed.Other References
