Reduced-pressure systems and methods employing a leak-detection member

A drape for disposing over a distribution manifold and at least a portion of intact epidermis to form a sealed space, the drape comprising:

• a film, the film being substantially transparent and configured to have an entry point;
• a first annulus of hydrophilic adhesive coupled to the film and configured to develop a color contrast in response to a leak, the first annulus of hydrophilic adhesive comprising a first plurality of rectangular deposits of hydrophilic adhesive disposed circumferentially around the entry point;
• and
• a second annulus of hydrophilic adhesive coupled to the film and configured to develop a color contrast in response to a leak, the second annulus of hydrophilic adhesive comprising a second plurality of rectangular deposits disposed circumferentially around the first annulus of hydrophilic adhesive;
• wherein the color contrast indicates a location of the leak.

A method of manufacturing a sealing member for treating a tissue site, the method comprising:

• providing a film, the film being substantially transparent;
• forming a first ring of hydrophilic adhesive in a first pattern, the first pattern comprising a plurality of rectangular deposits of hydrophilic adhesive disposed circumferentially around an entry point, each rectangular deposit having a short edge proximate to the entry point;
• coupling the first ring of hydrophilic adhesive to the sealing member;
• and
• coupling a second ring of hydrophilic adhesive to the sealing member formed in a second pattern, the second pattern comprising a plurality of rectangular deposits of hydrophilic adhesive disposed circumferentially around the first ring of hydrophilic adhesive;
• wherein the first ring of hydrophilic adhesive and the second ring of hydrophilic adhesive are configured to develop a color contrast in response to a leak.
