An improved skin substitute is presented comprised of a silicone layer backed up with a woven nylon fabric layer, the silicone layer possessing a regular pattern of slits that permit the porosity of the skin substitute to be adjusted by clinicians by means of applying tension to the skin substitute that differentially opens the slits. A variety of therapeutic substances can be applied to the skin substitute to promote healing, including aloe and other medicinal preparations. A layer of water soluble or water insoluble anti-scar compound is also present, the preferred compound being salinomycin.

Embodiments disclosed herein are directed to the treatment of wounds using negative pressure. Some embodiments disclosed herein provide for a foam pad, which may be suitable for use in abdominal wound sites, and which may be sized in a dimensionally-independent manner. Additional embodiments provide for a wound contact layer, as well as a system for the treatment of abdominal wounds.

A securement device for an infant including a lower layer having a silicone adhesive and a center opening configured to receive an umbilical cord of the infant. An upwardly extending first securement tab and an upwardly extending second securement tab are positioned on opposing sides of the center opening. The first securement tab and the second securement tab define a bridge capturing an umbilical line. The lower layer includes a first antimicrobial, and the first securement tab includes a second antimicrobial.

A dressing for treating tissue may be a composite of dressing layers, including a contact layer, a manifold layer, and an adhesive drape. The manifold layer may include one or more layers of felted open-cell foam in some examples. The manifold layer may be relatively thin to reduce the dressing profile and increase flexibility, which can enable it to conform to difficult geometry and other tissue sites under negative pressure. The dressing may have a length and a width less than the length. The manifold layer may include a population of holes extending at least partially therethrough, wherein the holes may be configured to promote anisotropic contraction of the dressing parallel to its width. The population of holes may have a circular, ovoid, triangular, square, hexagonal, irregular, or morphous shape. The dressing may be a bolster that may anisotropically contract to provide a closing force to a linear wound.

In one example embodiment, an apparatus for treating a tissue site may include a contact layer formed from a compressible material. The contact layer may include a plurality of apertures extending at least partially through the contact layer. The contact layer may be configurable such that at least a portion of the apertures include a first plurality of orifices having a diameter in a first diameter range and such that at least a portion of the apertures include a second plurality of orifices having a diameter in a second diameter range. The first diameter range may be from about 2 mm to about 6 mm. The second diameter range may be from about 8 mm to about 15 mm. The apparatus may include a cover configured to form a sealed space including the contact layer and the tissue site.

A medical dressing to treat sucking chest wound, and methods of forming the medical dressing. The methods include the steps of overlaying a cover layer on an intermediate layer and the intermediate layer on a base layer such that openings in the intermediate and base layers are aligned and the cover layer overlays the openings; fusing together the cover layer, the intermediate layer and the base layer by applying an annular welding tool face to at least one of the cover layer and base layer and applying welding energy to the template; and applying an adhesive layer on a side the base layer opposite to the intermediate layer, wherein the adhesive layer extends entirely around the opening.
