This invention provides compositions and methods of treating subjects with wounds. Compositions include dressings comprising a sheet and an adhesive, wherein the adhesive is adhered to the sheet, and wherein the sheet has channels. In some embodiments, the channels comprise two different classes of channels (e.g. liquid channels and air channels). These dressing can be applied to various kinds of skin injuries and remain affixed, protecting the injury from contaminants and at the same time, allowing exchange of exudates on the proximal (injury) side to the distal side and exchange of topical agents applied from the distal side of the dressing to the wound while also allowing exchange of gasses from the injury to the air and air to the wound.

A device comprising: a breast bandage hosting a cup portion, a reservoir portion, a gauze portion, and an adhesive portion, wherein the cup portion hosts the reservoir portion, wherein the gauze portion extends about the reservoir portion, wherein the adhesive portion is external to the reservoir portion.

A medical dressing for prevention of pressure ulcers is described. The dressing has a backing layer, a pad, and a body contact layer, wherein the pad is arranged between the backing layer and the body contact layer. The body contact layer has an adhesive skin contact layer and an anisotropic layer having a first (x) direction and a second (y) direction perpendicular to the first (x) direction. The anisotropic layer is stiffer in the second (y) direction than in the first (x) direction. The dressing reduces shear and compression forces on the skin and in the underlying soft tissue layers and prevents the onset of pressure ulcers.

The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.

A wound or access location dressing device can be used with a transcutaneous medical device such as a cannula, a catheter, or other transcutaneous interventional device. The dressing device is formed at least partially of a flexible hydrophillic polyurethane matrix, an antimicrobial agent contained within or coupled to the matrix, and a hemostatic agent contained within or coupled to the matrix.

Embodiments of apparatuses, systems, methods for monitoring wound pH are disclosed. In some embodiments, a wound dressing includes one or more optical sensors configured to measure a change in color of a pH-sensitive adhesive that changes color in response to changes in wound exudate pH. In some embodiments, the wound dressing may further comprise hydrophilic channels that direct wound exudate to a pH-sensitive material over the optical sensors. Such dressings may also be used in combination with a negative pressure wound therapy system.

A dressing for treating a tissue site, particularly a peritoneal or abdominal site, is disclosed. The dressing may comprise: a substrate; an adherent layer coupled to a surface of the substrate; and a fibrous layer comprising fibers coupled to a surface of the adherent layer opposite the substrate. Typically, the fibrous layer satisfies one or more of the following: at least 75% of the fibers are coupled approximately perpendicular to the surface of the substrate; at least 95% of the fibers in the fibrous layer have a length to diameter aspect ratio from about 10 to about 1000; and no more than 10% of the fibers are coupled approximately tangential to the surface of the substrate. Optionally, the fibrous layer may be formed by a flocking process. Methods of treating various tissue sites using the dressings and negative-pressure therapy are also disclosed.

An adhesive bandage is provided which has at least four arms instead of standard two where two of which being of a different length than other two to resist its removal from skin by a baby. The adhesive bandage includes a first and a second bandage arms and a third and a fourth bandage arms. The first and second bandage arms are transverse to the third and fourth bandage arms. The first and second bandage arms are longer in length to the third and fourth bandage arms. The adhesive bandage further includes a medicated pad at an intersection of the first and second bandage arms and the third and fourth bandage arms. In one embodiment, the new bandage includes an adhesive strip and a clip such that the adhesive strip is looped through the clip. In another embodiment, the new bandage includes an adhesive strip and a Velcro strap such that the adhesive strip is looped through the Velcro strap.

Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure. In one embodiment, a reduced-pressure dressing may include a dressing bolster, a retention pouch, and a sealing member. The dressing bolster may be adapted to apply a compressive force to the tissue site capable of closing a wound or incision therein. The retention pouch may be adapted to retain and manage fluid extracted from the tissue site to keep the tissue site substantially free of fluid and to prevent clogging of the reduced-pressure dressing. The sealing member may provide a seal over the retention pouch, the dressing bolster, and a portion of the epidermis of the patient. Other dressings, systems, and methods are disclosed.
