The present disclosure provides wound dressing compositions that disrupt biofilm formation in a wound upon application. The wound dressing composition includes a first layer comprising a homogeneous mixture of a collagen, an oxidized regenerated cellulose (ORC), and at least one bacteria reducing active ingredient and a second layer comprising a homogeneous mixture of a collagen, an oxidized regenerated cellulose (ORC), a silver compound, and at least one bacteria reducing active ingredient, and the uses thereof. Also disclosed herein are kits comprising the wound dressing compositions of the present technology, and instructions for use.

Layered collagen dressing with extended bacteria and biofilm reducing capabilities

An assembly includes a drape substantially sealable over a wound bed and a trackpad configured to couple a tube to the drape and allow the tube to provide suction to the wound bed. The assembly also includes a vent opening in the drape, a filter coupled to the drape and communicating with the vent opening, a cover coupled to the drape and movable between a first position to cover the vent opening and filter and a second position to uncover the vent opening and the filter, and a fluid indicator coupled to the drape and operable to provide a visual indication that fluid build-up is present in the wound bed.
