Wound dressings and systems with high-flow therapeutic gas sources for topical wound therapy and related methods

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.

Shear resistant wound dressing for use in vacuum wound therapy

A cover layer for a vacuum wound therapy dressing includes a backing layer formed from a flexible polymeric membrane and an adhesive layer for affixing the backing layer over a wound bed to provide a substantially fluid-tight seal around a perimeter of the wound bed. The cover layer is reinforced with a reinforcement layer extending to a peripheral region of the backing layer to distribute forces associated with evacuating a reservoir, as defined by or within the cover, to stimulate healing of the wound bed.

Occlusive chest wound seal with a one-way vent for preventing and treating tension pneumothorax

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.
