Disclosed herein are several embodiments of a wound treatment apparatus employing glue on the backing layer of a wound dressing. In some embodiments, the glue limits saturation of an absorbent layer beneath the backing layer.

An evaporative bridge dressing that may be used with negative-pressure treatment of tissue. The evaporative bridge dressing may have one or more fluid transfer layers comprised of high-density wicking material enclosed between layers of film having high moisture-vapor transfer rates to manage liquid storage and pressure drop. The evaporative bridge may have an absorbent in some embodiments. An evaporation channel may be disposed adjacent to or combined with the evaporative bridge. A means for measuring pressure across the evaporative bridge may include a feedback path. A support means may reduce or prevent collapse of one or more of the evaporative bridge, the evaporation channel, the feedback path.

A cover for protecting a tissue site may comprise a shell layer, an adhesive disposed on the shell layer, and a contact layer disposed adjacent to the adhesive. The contact layer may have a first pattern of apertures and bridges, and the shell layer may have a second pattern of apertures overlaying the bridges. In some examples, the adhesive may have a bond strength that is greater than the tensile modulus of the shell layer. The contact layer may have an open area of about 40 percent to about 50 percent of the total area of the contact layer. A release liner may be disposed adjacent to the contact layer. Perforations through the shell layer and the contact layer can define a sacrificial segment configured to be separated from the shell layer and the contact layer. A handling bar may be coupled to the sacrificial segment.

A system, method, and apparatus are disclosed for dressing a wound and for minimizing scarring. The apparatus promotes scar-minimizing healing of a wound where negative pressure wound therapy is applied, and comprises a wound contact layer containing silicone, polysiloxanes, or other related compounds.

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

This disclosure relates to a wound care device which contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device contains a perforated adhesive layer.

In some examples, a dressing suitable for treating a tissue site may include a fluid management assembly configured to offload fluid extracted from the tissue site away from an articulation area at the tissue site. Other features may be associated with the dressing including, without limitation, a base layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.

In some examples, a dressing suitable for treating a tissue site may include a fluid management assembly including a fluid restraint configured to reduce a fluid capacity of the fluid management assembly proximate to the fluid restraint. Other features may be associated with the dressing including, by way of example and without limitation, abase layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.

A method and apparatus are disclosed for dressing a wound. The apparatus comprises an absorbent layer for absorbing wound exudate, a liquid impermeable, gas permeable filter layer over the absorbent layer, a cover layer comprising at least one orifice and a first liquid and gas permeable transmission layer underlying the absorbent layer. The transmission layer is in fluid communication with the filter layer.

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein and a stabilizing structure that may aid in wound closure.
