1. A dressing interface for connecting a negative-pressure source to a dressing, the dressing interface comprising:
a coupling member configured to be coupled to a cover of the dressing, the coupling member comprising:
a contact layer comprising a first aperture;
a shell layer coupled to the contact layer and configured to be opposite the cover, the shell layer having a second aperture;
a first adhesive region having a first region peel strength;
a second adhesive region having a second region peel strength less than the first region peel strength;
a hinge line between the first adhesive region and the second adhesive region, with the first adhesive region located on a first side of the hinge line and the second adhesive region on a second side of the hinge line, the second side opposite the first side; and
an aperture formed by the first aperture and the second aperture, the aperture located in the second adhesive region on the second side of the hinge line; and
a negative-pressure port for the delivery of negative pressure, the negative-pressure port comprising:
a flange coupled to the shell layer located in the first aperture of the contact layer; and
a conduit housing coupled to the flange and extending through the second aperture in the shell layer.
