Abstract

A self adherent window dressing includes a fabric tape layer having an adhesive side and an opposite non-adhesive side. The fabric tape layer has an opening therein to allow viewing of a wound or injection site therethrough. A semipermeable transparent film layer closes the opening in the fabric tape layer. The transparent film layer has an adhesive side and an opposite non-adhesive side. The film layer adhesive side is adhered on the non-adhesive side of the fabric layer around the opening. An absorbent fiber layer having an opening generally corresponding to the opening in the fabric tape layer is mounted on the adhesive side of the fabric tape layer such that the openings in the absorbent fiber and fabric tape layers are in alignment and the fabric tape layer extends beyond the periphery of the absorbent fiber layer. A non-adherent porous film layer of a shape generally corresponding to the shape of the absorbent layer is adhered to the fiber layer.

Claims

1. A self adherent window dressing comprising:

a fabric tape layer having an adhesive side and an opposite non-adhesive side;

said fabric tape layer having an opening therein to allow viewing therethrough;

a skin adhering, gas permeable, liquid impermeable transparent film layer closing said opening in said fabric tape layer and having an adhesive side and an opposite non-adhesive side;

said film layer adhesive side being adhered on the non-adhesive side of said fabric tape layer around said opening and on the surface of the skin on which it is mounted for maintaining normal skin function;

a wicking fiber layer having an opening generally corresponding to said opening in said fabric tape layer, said fiber layer mounted on the adhesive side of said fabric tape layer such that said openings in said wicking fiber and fabric tape layers are in alignment and said fabric tape layer extends beyond the periphery of said wicking fiber layer; and

a non-adherent porous film layer of a shape generally corresponding to the shape of said wicking fiber layer adhered to said wicking fiber layer.

2. The window dressing of claim 1 including a removable paper of a shape corresponding to the shape of said fabric tape layer, said paper disposed over said absorbent and non-adherent porous film layer against the adhesive side of said fabric tape layer extending beyond said absorbent fiber layer periphery.

3. The window dressing of claim 2 wherein said paper is silicone-coated.

4. The window dressing of claim 1 wherein said gas permeable, liquid impermeable transparent film layer comprises a liquid impermeable polyurethane film coated with a medical grade adhesive.

5. The window dressing of claim 4 wherein said polyurethane film is impermeable to microcontaminants.

6. The window dressing of claim 1 wherein said fabric layer adhesive side is coated with a hypoallergenic adhesive.

7. The window dressing of claim 1 wherein said wicking fiber layer is a lint free, nonwoven fabric.

8. The window dressing of claim 1 wherein said wicking fiber layer includes an opening therein.

9. The window dressing of claim 1 wherein said non-adherent porous film layer comprises polyethylene film.

10. The window dressing of claim 9 wherein said polyethylene film is heat laminated to said absorbent fiber layer.

11. A self adherent window dressing comprising:

a fabric tape layer having an adhesive side coated with a hypoallergenic adhesive and an opposite non-adhesive side;

said fabric tape layer having an opening therein to allow viewing therethrough;

a gas and moisture vapor permeable, liquid impermeable transparent film layer closing said opening in said fabric tape layer and having an adhesive side and an opposite non-adhesive side;

said film layer adhesive side being adhered on the non-adhesive side of said fabric layer around said opening;

a wicking, nonwoven fiber layer having an opening generally corresponding to said opening in said fabric tape layer, said fiber layer mounted on the adhesive side of said fabric tape layer such that said openings in said fiber and fabric tape layers are in alignment and said fabric tape layer extends beyond the periphery of said wicking fiber layer; and

a non-adherent porous film layer of a shape generally corresponding to the shape of said wicking fiber layer adhered to said fiber layer.
