A wound dressing is selectively configurable for use in a pressure gradient wound therapy system and for use without a pressure gradient wound therapy system. The wound dressing can include a covering layer, an aperture and a microbial barrier. The microbial barrier can be arranged to cover the aperture.

Hemostatic devices for promoting blood clotting can include a substrate (e.g., gauze, textile, sponge, sponge matrix, one or more fibers, etc.), a hemostatic material disposed thereon such as kaolin clay, and a binder material such as crosslinked calcium alginate with a high guluronate monomer molar percentage disposed on the substrate to substantially retain the hemostatic material material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood to accelerate clotting. Moreover, when exposed to blood, the binder has low solubility and retains a majority of the clay material on the gauze. A bandage that can be applied to a bleeding wound to promote blood clotting includes a flexible substrate and a gauze substrate mounted thereon.

A liquid film cleavage agent having a spreading coefficient of 15 mN/m or more to a liquid having surface tension of 50 mN/m, and a water solubility of 0 g or more and 0.025 g or less.
