Abstract: A tissue interface configured to be positioned at a tissue site is provided. The tissue interface may include a first tissue interface layer, a second tissue interface layer, and a bonding layer disposed between the first tissue interface layer and the second tissue interface layer. The bonding layer may couple the first tissue interface layer to the second tissue interface layer. The interface layers may be bonded together lightly such that the bonding layer is sufficiently strong to hold together a first interface layer and a second interface layer, but weak enough to allow the first tissue interface layer to be separated or detached from the second tissue interface layer when pulled apart by a user. This allows a user to add or remove any number of tissue interface layers to adjust the height of the tissue interface 108 in order to accommodate the depth of a tissue site.

Abstract: A negative pressure wound therapy system includes at least one sensor coupled to a wound dressing for a wound of a patient, and a control circuit. The at least one sensor is configured to output an indication of a displacement of the wound dressing. The control circuit is configured to receive the indication of the displacement of the wound dressing, calculate a therapy parameter corresponding to the indication of the displacement, and output the therapy parameter.

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: An apparatus for filling a wound can include an array of at least four truncated ellipsoids interconnected to define at least one fluid path through, for example perpendicular to, the array. The longest principal axis of each ellipsoid may be perpendicular to the array. Each truncated ellipsoid may be a spheroid and/or may include an approximately elliptical contact surface at each contact surface between two interconnected ellipsoids. Each fluid pathway may have four continuously-curved concave sides and may have a parallelogram-shaped cross-section with continuously-curved concave edges. A dressing may include the apparatus, a dressing layer coupled to the apparatus, a backing layer disposed over a surface of the dressing layer opposite the apparatus, and an attachment device disposed on at least a margin of the backing layer. Methods of treating various tissue sites using the apparatus or dressing with negative-pressure therapy are also disclosed.

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.

Abstract: A system for applying reduced pressure to tissue includes a multi-lumen reduced pressure delivery tube having a proximate end, a distal end, a primary lumen extending through the conduit from the proximate end to the distal end, and an ancillary lumen extending through the conduit from the proximate end to the distal end. A vacuum pump is coupled to the proximate end of the primary lumen, and a reduced pressure adapter is coupled to the distal end of the reduced pressure delivery tube. The adapter includes channels to direct liquid away from the ancillary lumens and into the primary lumen.

Abstract: A dressing for treating a tissue site with negative pressure may comprise a tissue interface comprising a three-dimensional textile of polyester fibers and a polymer coating on the polyester fibers. In some examples, the three-dimensional textile may be a three-dimensional weave of polyester fibers, and the polymer coating may be hydrophobic. In more particular embodiments, the polymer coating may be silicone or polyethylene, for example. The dressing may additionally include a drape disposed over the tissue interface and a port fluidly coupled to the tissue interface through the drape. The tissue interface may be applied over a tissue site, and therapeutic levels of negative pressure may be applied to the tissue site through the tissue interface.

Abstract: Systems and methods are provided for moving fluids from a patient to a canister and lowering or eliminating the bio-burden of the canister. In one instance, a method for removing fluids from a patient includes using reduced pressure to remove fluids from a patient, delivering the fluids into a reduced-pressure conduit and into a fluid reservoir, exposing the fluids removed from the patient to a UV light source to kill pathogens to create disposable fluids, and disposing of the disposable fluids. Other systems, devices, and methods are presented.
