Window dressing
First Claim
1. A self adherent dermal wound window dressing for the protection of an indwelling catheter access site, and which provides the simultaneous absorption and continuous mitigation of moisture vapor, visualization of the skin/cannula exit point and mechanical securement of the indwelling catheter, the window dressing comprising:
- a fabric tape layer having an adhesive skin adhering side and an opposite non-adhesive side;
said fabric tape layer having an opening therein to allow viewing therethrough;
a semipermeable transparent film layer closing said opening in said fabric tape layer and having an adhesive skin adhering side and an opposite non-adhesive side;
said film layer non-adhesive side being adhered on the adhesive side of said fabric layer around said opening such that said fabric layer extends beyond the periphery of said transparent film layer; and
an absorbent fiber layer having an opening generally corresponding to said opening in said fabric tape layer, said fiber layer being mounted on the adhesive skin adhering side of said transparent film layer such that said openings in said absorbent fiber and fabric tape layers are in alignment and said transparent film layer extends beyond the periphery of said absorbent fiber layer.

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

2. A self adherent dermal wound window dressing for the protection of an indwelling catheter access site, and which provides the simultaneous absorption and continuous mitigation of moisture vapor, visualization of the skin/cannula exit point and mechanical securement of the indwelling catheter, the window dressing comprising:
-
a fabric tape layer having an adhesive skin adhering side and an opposite non-adhesive side;
said fabric tape layer having an opening therein to allow viewing therethrough;
a semipermeable transparent film layer closing said opening in said fabric tape layer and having an adhesive skin adhering side and an opposite non-adhesive side;
said film layer non-adhesive side being adhered on the adhesive side of said fabric layer around said opening such that said fabric layer extends beyond the periphery of said transparent film layer; and
an absorbent fiber layer having an opening generally corresponding to said opening in said fabric tape layer, said fiber layer being mounted on the adhesive skin adhering side of said transparent film layer such that said openings in said absorbent fiber and fabric tape layers are in alignment, and said absorbent fiber layer shares the same outer periphery shape and size of said transparent film layer;
the absorbent fiber layer void of adhesive is thereby held proximal to the skin by the said adhesive transparent film layer in the central opening and continually adjoining the skin beyond the said absorbent fiber layer by the said adhesive fabric tape layer extending beyond the shared outer periphery of the said absorbent fiber and adhesive film layers.

3. A self adherent dermal wound window dressing for the protection of an indwelling catheter access site, and which provides the simultaneous absorption and continuous mitigation of moisture vapor, visualization of the skin/cannula exit point and mechanical securement of the indwelling catheter, the window dressing comprising:
-
a fabric tape layer having an adhesive skin adhering side and an opposite non-adhesive side;
said fabric tape layer having an opening therein to allow viewing therethrough;
a semipermeable transparent film layer closing said opening in said fabric tape layer and having an adhesive skin adhering side and an opposite non-adhesive side;
said film layer non-adhesive side being adhered on the adhesive side of said fabric layer around said opening such that said fabric layer extends beyond the periphery of said transparent film layer; and
an absorbent fiber layer having an opening generally corresponding to said opening in said fabric tape layer, said fiber layer being mounted on the adhesive skin adhering side of said transparent film layer such that said openings in said absorbent fiber and fabric tape layers are in alignment, and the outer perimeter of said absorbent fiber layer is unequal in size to said transparent adhesive film layer and extends beyond at least one edge of said film layer concurrently contacting and adhering to the adhesive side of the larger said adhesive fabric tape layer;
the absorbent fiber layer void of adhesive is thereby held proximal to the skin by the said adhesive transparent film layer in the central opening, and by the larger said adhesive fabric tape layer continually adjoining the skin beyond the said fiber layer concurrently contacting and adhering to the said fiber layer extending beyond at least one edge of said transparent film layer.

4. A self adherent dermal wound window dressing for the protection of an indwelling catheter access site, and which provides the simultaneous absorption and continuous mitigation of moisture vapor, visualization of the skin/cannula exit point and mechanical securement of the indwelling catheter, the 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 semipermeable transparent film layer void of adhesive closing said opening in said fabric tape layer and having a periphery greater than a periphery of said opening and less than a periphery of said fabric tape layer; and
an absorbent fiber layer void of an adhesive having an opening generally corresponding to said opening in said fabric tape layer, said fiber layer being mounted on the adhesive side of said fabric tape layer such that said openings in said absorbent fiber and fabric tape layers are in alignment and said absorbent fiber layer extends beyond the periphery of said transparent film layer and said fabric tape layer extends beyond the periphery of said absorbent fiber layer.
