Abstract: A bodily fluid collection system may include a canister fluidly connected to a dressing at a tissue site through an inlet. The canister may also be fluidly connected to a reduced pressure source through an outlet. At least a portion of the wall of the canister may be a membrane and may have the open edge of a flexible bag container fixed to the canister surrounding the perimeter of the membrane. The flexible bag may contain an osmotic agent capable of drawing absorbent from bodily fluid in the canister through the membrane and into the flexible bag.

Abstract: The illustrative embodiments described herein are directed to an apparatus, system, and method for storing liquid from a tissue site. The apparatus may include a drape having an aperture, and a fluid pouch coupled to the drape such that the fluid pouch is in fluid communication with the aperture. In one embodiment, the fluid pouch is operable to transfer reduced pressure to the aperture such that the liquid from the tissue site is drawn into the fluid pouch. The fluid pouch may have a cavity that stores the liquid that is drawn from the tissue site. In another embodiment, the fluid pouch may include at least one baffle. The fluid pouch may also include a fluid channel at least partially defined by the at least one baffle. The fluid channel may be operable to store liquid from the tissue site when reduced pressure is applied through the fluid channel.

Abstract: A flexible dressing for applying to a tissue site for determining the extent of debridement required to remove non-viable tissue is disclosed. Some embodiments of the dressing may be in the form of a multi-layer drape having an integrated tissue viability indicator system. Some embodiments may also include a system of shapes or a grid pattern printed or embossed on a surface of the drape for providing guidance during an ensuing debridement or amputation procedure.

Abstract: A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.

Abstract: Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.
