Abstract
Trimmable conformable wound dressings, kits containing the same and methods of using the same. The wound dressings may protect a treatment site from microbial contamination or other disturbances while a wound heals or to enable the application and maintenance of vacuum over the treatment site. The wound dressings may include first and second sections of support layer material on opposite sides of one or more intermediate sections of support layer material. The first and second sections of support layer material meet the intermediate sections of support layer material along peel tab junctions that provide peel tabs.
Claims19
A wound dressing comprising:
- an elastic film backing comprising a first major surface, a second major surface opposite the first major surface, and a perimeter that includes a first end, a second end opposite the first end, first and second lateral edges, the lateral edges extending from the first end to the second end, and a longitudinal axis extending from the first end to the second end;
- adhesive disposed on the first major surface of the backing;
- and
- a support layer attached to the second major surface of the backing, wherein the support layer comprises a first section, a second section, and an intermediate section, wherein each of the first, second, and intermediate sections extend from the first end to the second end, wherein the first section extends from the first lateral edge of the backing to a first tab junction with the intermediate section, wherein the second section extends from the second lateral edge of the backing to a second tab junction with the intermediate section;
- wherein the support layer of the first tab junction comprises a first separation feature extending from the first end to the second end along the first tab junction;
- wherein the support layer of the second tab junction comprises a second separation feature extending from the first end to the second end along the second tab junction;
- wherein the intermediate section of the support layer comprises an intermediate frame that extends around at least a portion of the perimeter of the intermediate section, and a plurality of intermediate windows arranged along the longitudinal axis, wherein the second major surface of the backing is exposed within each intermediate window of the plurality of intermediate windows, and wherein each pair of adjacent intermediate windows is separated from each other by an intermediate strut.
