摘要： The wound dressing described herein can be used as a contact layer dressing. The wound dressing can be positioned between a wound bed and a secondary dressing. The wound dressing can include a layered construction. Each of the layers can include a bioresorbable sponge enclosed within a collagen-based film. The wound dressing can include a plurality of fluid channels that enable fluid flow from the wound bed toward the environment-face side of the wound dressing.

摘要： The wound dressing described herein includes a backing layer, absorbent layer, and foam layer. The wound dressing also includes one or more visual indicators. The visual indicators are substantially non-visible in their initial, dehydrated state. As the visual indicators absorb fluid they swell and become visible. The visual indicators enable a caregiver to know when the wound dressing has reached, or is about to reach, its fluid capacity.

摘要： An antimicrobial composition may comprise a surfactant. The antimicrobial composition may include about 30 μg/ml to about 1,000 μg/ml of the surfactant, by volume of the antimicrobial composition. The surfactant may comprise a docusate salt such as docusate sodium. The antimicrobial composition may comprise an antimicrobial agent. The antimicrobial composition may include from about 0.01% to about 10% of the antimicrobial agent, by weight of the antimicrobial composition. The antimicrobial agent may comprise polyhexanide (PHMB). In some embodiments, the antimicrobial composition may comprise a matrix-forming material. The antimicrobial composition may include at least 90% of the matrix- forming material, by weight of the antimicrobial composition. The matrix-forming material may comprise collagen, oxidized regenerated cellulose, alginate, carboxymethylcellulose, or combinations thereof.

摘要： The present disclosure relates generally to wound dressings and reduced-pressure wound dressing apparatuses that detect the presence of proteases in a wound upon application. The wound dressings and the reduced-pressure wound dressing apparatus of the present technology can be a visual indicator of the presence of proteases in a wound; and a visual indicator of the wounds healing status.
