Abstract

A 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.

Claims

1. A dressing for covering a patient'"'"'s skin comprising:

an outer skin-contacting layer having an opening substantially surrounded by said outer layer

a pliable transparent inner skin-contacting membrane positioned throughout said opening wherein a perimeter of said outer layer substantially surrounds said membrane; and

an adhesive layer on a bottom surface of said outer layer such that said membrane is secured to a portion of said outer layer and said perimeter of said outer layer forms an adhesive perimeter in order that said dressing is adhered to such patient'"'"'s skin only at said adhesive perimeter.

2. The dressing according to claim 1, wherein said outer layer is formed of a semi-rigid foam material.

3. The dressing according to claim 2, wherein said transparent membrane consists of an air permeable pliable material such that said dressing allows visual observation of such patient'"'"'s skin.

4. The dressing according to claim 2, further comprising a liner located below said membrane and attached to said adhesive perimeter, exposing said adhesive perimeter for contact with such patient'"'"'s skin.

5. The dressing according to claim 4, wherein said liner consists of a paper material.

6. The dressing according to claim 1, wherein said outer layer, said membrane and said opening are rectangular.

7. The dressing according to claim 1, wherein said outer layer, said membrane and said opening are circular.

8. The dressing according to claim 1, wherein said outer layer further comprises a pair of finger portions, each pair extending from opposed ends of said outer layer such that said outer layer forms a substantially "H" shaped dressing.

9. A dressing for a patient'"'"'s skin, comprising:

an outer layer surrounding a window opening;

a pliable transparent inner skin-contacting layer attached to said outer layer and extending throughout said window opening; and

an adhesive border formed on said outer layer around the perimeter of said inner layer such that when adhered to such patient'"'"'s skin a chosen area of skin shows through said window opening.

10. A method for applying a dressing comprising a pliable transparent membrane attached at its perimeter to a semi-rigid adhesive border having a liner secured to said adhesive border, comprising the steps of:

removing said liner from said adhesive border in order to expose a tacky adhesive surface;

centering said transparent membrane over a wound such that said window contacts such wound; and

applying said dressing to such wound in order that said tacky adhesive surface substantially contacts skin surrounding such wound rendering such wound entirely visible through said transparent membrane as well as isolated from contact with said semi-rigid adhesive border.

11. A dressing for covering a patient'"'"'s skin, comprising:

an adhesive frame having an opening substantially surrounded by said adhesive frame; and

a pliable transparent non-adhesive skin-contacting membrane attached to said frame and extending throughout said opening where a portion of said adhesive frame extends beyond said membrane and forms an adhesive border to substantially adhere said transparent dressing to such skin at said adhesive border.

12. The dressing according to claim 11, wherein said adhesive frame is formed of a semi-rigid foam material.

13. The dressing according to claim 11, wherein said adhesive frame consists of a single piece of material.

14. The dressing according to claim 11, wherein said adhesive frame substantially retains the shape of said dressing when packaged.

15. The dressing according to claim 11, wherein said transparent membrane consists of an air permeable pliable material such that said dressing allows visual observation of a patient'"'"'s wound.

16. The dressing according to claim 11, wherein said transparent membrane is hypo-allergenic allowing the passage of vapor and gases through said transparent membrane in one direction and blocking contaminants and moisture coming into said transparent membrane in a second direction.

17. The dressing according to claim 11, further comprising a liner located on a skin contacting surface of said transparent membrane and attached to said adhesive border such that said liner is adapted to be peeled off of said adhesive border, exposing said adhesive border and transparent membrane to a patient'"'"'s skin.

18. The dressing according to claim 17, wherein said liner consists of a paper material.

19. The dressing according to claim 11, wherein said adhesive frame is coated with a hypo-allergenic synthetic acrylic pressure sensitive adhesive of sufficient tackiness to seal a wound from a liquid and/or air seepage into said dressing.

20. The dressing according to claim 19, wherein a first adhesive is employed to adhere said transparent membrane to said adhesive frame and a second adhesive is employed to adhere to said transparent dressing to such patient'"'"'s skin.

21. A transparent dressing for covering a patient'"'"'s wound, comprising:

a frame having an opening substantially surrounded by said frame;

a transparent non-adhesive skin-contacting membrane positioned below said frame and throughout said opening wherein a perimeter of said frame substantially surrounds said transparent membrane;

an adhesive layer on a skin contacting surface of said frame such that said membrane is secured to a portion of said frame and said frame portion that extends beyond said membrane forms an adhesive border enabling said transparent dressing to be adhered to a patient'"'"'s skin at said adhesive border; and

a flap for substantially covering said opening.

22. The dressing according to claim 21, wherein said flap is formed integrally with said frame.

23. The dressing according to claim 21, wherein said flap is made of a substantially air permeable material.

24. The dressing according to claim 21, wherein said flap has a plurality of air holes such that gas passes through said flap.

25. The dressing according to claim 21, wherein the perimeter of said flap is larger than the perimeter of said opening.
