Systems and apparatuses for administering reduced pressure treatment to a tissue site include a reduced pressure source, a drape having a plurality of projections for contacting the tissue site, and an adhesive connected to at least a portion of the drape for sealing the drape to a portion of a patient's intact epidermis.

A dressing configured to be positioned adjacent to a tissue site is disclosed herein. The dressing may include oxidized regenerated cellulose (ORC), collagen, and at least one nutrient including glutamine. Methods of treating a tissue site are also disclosed herein.

A cranial cap dressing for dressing a craniotomy wound comprising a breathable elastic outer layer sized to fit snuggly on a human head of a patient and an absorbent inner layer attached to the breathable elastic outer layer.

This disclosure includes wound dressings and systems with high-flow therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; and a gas-occlusive layer configured to be disposed over the manifold and coupled to the tissue such that an interior volume containing the manifold is defined between the gas-occlusive layer and the tissue and the gas- occlusive layer limits escape of therapeutic gas from the interior volume; wherein the gas- occlusive layer includes: a first opening configured to allow communication of therapeutic gas into the interior volume; and one or more second openings configured to allow communication of therapeutic gas out of the interior volume.

A dressing consists substantially of a hydrophilic membrane layer, a superabsorbent material positioned on the hydrophilic membrane layer, and a film layer coupled to the hydrophilic membrane layer and configured to confine the superabsorbent material between the film layer and the hydrophilic membrane layer. The film layer has a high moisture vapor transfer rate.

A vented chest wound seal for a penetrating chest wound includes a flexible sheet including a top surface and a bottom surface, an adhesive hydrogel layer covering a portion of the bottom surface of the flexible sheet, and a plurality of vent channels. The adhesive hydrogel layer includes an inner perimeter and an outer perimeter, and the outer perimeter forms a continuous perimeter of hydrogel along a bottom surface of the flexible sheet. A plurality of vent channels, each including a first opening to a space inside of the inner perimeter, extend radially outward to an outer terminal end vent to the top surface of the flexible sheet. The outer terminal end is spaced apart from the outer perimeter of the adhesive hydrogel layer towards the central portion of the chamber.

A wound dressing includes a superabsorbent layer, a backing layer, and a charcoal layer. The superabsorbent layer is configured to absorb wound fluid and has a first side and a second, wound-facing side. The backing layer also has a first side and a second, wound-facing side. The backing layer is substantially impermeable to liquid and substantially permeable to vapor. The charcoal layer is positioned between the first side of the superabsorbent layer and the second, wound-facing side of the backing layer. The charcoal layer is configured to increase a moisture vapor transmission rate of the wound dressing.

A cranial cap dressing for dressing a craniotomy wound comprising a breathable elastic outer layer sized to fit snuggly on a human head of a patient and an absorbent inner layer attached to the breathable elastic outer layer.

A dressing configured to be positioned adjacent to a tissue site is disclosed herein. The dressing may include oxidized regenerated cellulose (ORC), collagen, and at least one nutrient including glutamine. Methods of treating a tissue site are also disclosed herein.

In some examples, a dressing suitable for treating a tissue site may include a sealing member having a periphery and a central portion. The central portion of the sealing member may include a breathable zone having a higher vapor permeability than the periphery of the sealing member. Other features may be associated with the dressing including, by way of example and without limitation, a base layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.
