Dermal wound window dressing securement system

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 or cannula exit point and mechanical securement of the indwelling catheter, the 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;
• an absorbent, 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 absorbent fiber layer;
• a non-adherent porous film layer of a shape generally corresponding to the shape of said absorbent fiber layer having an adhesive side and an opposite non-adhesive side and adhered to said fiber layer by said adhesive side of said non-adherent porous film layer;
• and
• an overt notch formed by removal of a portion of the fabric tape layer extending beyond the periphery of said absorbent fiber layer for receiving a catheter tube extending from under the dressing.
