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.

Claims

1. A transparent dressing for a tracheostomy tube comprising:

a frame having an opening substantially surrounded by said frame;

a transparent non-adhesive membrane positioned below said frame and over said opening wherein a perimeter of said frame substantially surrounds said transparent membrane, said membrane having a central aperture for accommodating said tracheostomy tube through said aperture;

an adhesive layer on a bottom 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 such that said transparent dressing is adhered to a patient'"'"'s skin by said adhesive border; and

a pair of ties each having a first end attached to said frame and a second end adapted to attach said tracheostomy tube extending through said central aperture to said frame.

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

3. The transparent dressing according to claim 2, wherein said transparent membrane consists of an air permeable flexible material such that said transparent dressing allows visual observation of tracheostomy wound.

4. The transparent dressing according to claim 2, further comprising a liner located below said 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 for contact with such patient'"'"'s skin.

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

6. The transparent dressing according to claim 1, wherein said frame and said transparent membrane are substantially rectangular.

7. The transparent dressing according to claim 1, wherein said frame, and said transparent membrane and opening are substantially circular.

8. The transparent dressing according to claim 1, wherein said central aperture contacts a slit that extends from one edge of said central aperture to an edge of said transparent dressing such that said central aperture can hold said tracheostomy tube to such skin while accommodating curvatures in a patient'"'"'s neck and still prevent contaminants or liquid from entering a wound site.

9. The transparent dressing according to claim 8, further comprising a semi-rigid flexible collar surrounding said tube hole and located on the top and bottom surfaces of said transparent membrane.

10. The transparent dressing according to claim 9, wherein said collar comprises a top collar member located above all transparent membrane and a bottom collar member located below said transparent membrane whereby said top and bottom collar members have respective adhesive surfaces enabling said collar members to be adhered to said top and bottom surfaces of said transparent membrane, to a patient'"'"'s skin and to said tracheostomy tube.

11. The transparent dressing according to claim 10, wherein said first end of each of said ties includes a loop material and said second end of each of said ties includes a hook material whereby a respective second end is adapted to mate with a respective first end of each of said ties.

12. The transparent dressing according to claim 11, wherein each of said second ends is adapted to loop through a slit located on said tracheostomy tube and back toward said respective first end of each of said tie thus firmly securing said tracheostomy tube to said transparent dressing.

13. A dressing for a tube, comprising:

a frame member surrounding a window;

a transparent membrane attached to said frame member, and covering said window and having a tube opening for accommodating a tracheostomy tube;

an adhesive border formed on said frame around the perimeter of said transparent membrane such that when adhered to a patient'"'"'s skin, a chosen area of such skin shows through said membrane covered window opening; and

a pair of ties attached to said frame member wherein each of said ties is adapted to secure said tube to said frame thereby holding said tube in place in said tube opening.

14. The dressing according to claim 13, wherein said frame member incorporates a slit extending from said tube opening to an end of said frame member to prevent lifting up of said dressing when said tube is inserted into said dressing and to insure said dressing is sealed around said tube such that contaminants and fluids are prevented from entering said dressing.
