Abstract: This disclosure describes devices, systems, and methods related to oxygenated hemoglobin, the generation thereof, and the use thereof. An exemplary oxygenated hemoglobin therapy system includes an oxygen source configured to provide oxygen and a hemoglobin source configured to provide topical hemoglobin. The therapy system may also include a mixer which has a first inlet, a second inlet, and an outlet. The mixer is configured to mix the oxygen and the topical hemoglobin to form a mixture and to provide the mixture to a dressing via the outlet. The therapy system may further include the dressing. The oxygenated hemoglobin therapy systems described herein are suitable for use in medical devices, such as bandages, drapes, dressings, and wound closures.

Abstract: This disclosure describes devices, systems, and methods related to therapy devices including pumps that are operable in multiple operating modes. An exemplary wound therapy device includes a pump configured to be worn by a user and a controller coupled to the pump and configured to transition the pump from operating in a first operating mode to operating in a second operating mode responsive to a pressure of the wound therapy device satisfying a first pressure threshold. The first operating mode is associated with a first drive voltage that is different from a second drive voltage associated with the second operating mode.

Abstract: A system or apparatus including a dressing, a dressing interface, and a humidity sensor may be suitable for use with systems and methods for treating a tissue site. Embodiments of the apparatus are provided for treating a tissue site with reduced pressure provided by a source of reduced pressure. The dressing may include abase layer, a sealing member disposed proximate the base layer to define an enclosure providing a sealed space over the tissue site, and an absorbent member disposed within the enclosure. The dressing interface may comprise a reduced-pressure port configured to be coupled to the source of reduced pressure and a therapy port covered by a hydrophobic filter defining a reduced-pressure pathway between the hydrophobic filter and the source of reduced pressure. The humidity sensor may comprise a sensing portion fluidly coupled to the reduced-pressure pathway and an output for providing a humidity signal that indicates the amount of fluid extracted from the tissue site and stored by the absorbent member. Other dressings, systems, and methods are disclosed.

Abstract: A sampling interface may comprise an inlet port, an outlet port, and a sampling chamber between the inlet port and the outlet port. The apparatus may also comprise a sampling port and at least one split seal between the sampling port and the sampling chamber. The split seal may comprise a first sealing member and a second sealing member that converge to a sealing line. The apparatus may additionally include at least one fluid collection channel disposed interior to the split seal. A lateral flow strip for sampling fluid removed from a tissue site may comprise an acquisition surface and a migration medium fluidly coupled to the acquisition surface. At least one test medium may be fluidly coupled to the migration medium, and a liquid-impermeable cover may enclose the migration medium and the test medium. The acquisition surface is preferably not enclosed.

Abstract: A portable therapy system for treating a tissue site, particularly a venous leg ulcer, is disclosed. In some embodiments, the therapy system may include a bridge, a dressing, or both, which contain a material suitable for binding bacteria and/or protein. Such a binding material may be used in conjunction with one or more manifold or wicking layers disposed within the bridge or the dressing to help contain bacteria and/or protein present in fluid extracted from the tissue site, such as wound exudate. By binding the bacteria and/or protein present in wound exudate, particularly wound exudate that may possess a high viscosity due to a greater concentration of proteins, blockages and associated pressure drops across the components of the therapy system may thus be minimized or avoided.

Abstract: Provided herein is a system and method for mitigating premature light deactivation of light deactivated adhesive drapes. One aspect provides a system comprising a drape, an adhesive layer, and a release agent, where the system is adapted to be coupled to a tissue site and released therefrom upon or after exposure to an external stimulus such as certain wavelengths of light. The system may have a photochromic layer that may transition between a blocking transmittance state and a non-blocking transmittance state to block or allow certain wavelengths of light to pass through. Some systems may use a combination of a photochromic layer and a filter layer to prevent the adhesive from being exposed to deactivation wavelengths prematurely. Another aspect provides a method for application and removal of a drape using by removing one or more of a photochromic layer and a filter layer and applying light to the drape to deactivate the adhesive layer and promote easy, clean, and less painful removal of the drape.

Abstract: A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

Abstract: This disclosure includes wound dressings and systems with high-flow therapeutic gas sources for topical wound therapy and related methods. Some dressings, which are configured to be coupled to tissue to facilitate delivery of therapeutic gas to the tissue, comprise a manifold that defines a plurality of gas passageways, the manifold configured to allow communication of therapeutic gas to the tissue; and a gas-occlusive layer configured to be disposed over the manifold and coupled to the tissue such that an interior volume containing the manifold is defined between the gas-occlusive layer and the tissue and the gas- occlusive layer limits escape of therapeutic gas from the interior volume; wherein the gas- occlusive layer includes: a first opening configured to allow communication of therapeutic gas into the interior volume; and one or more second openings configured to allow communication of therapeutic gas out of the interior volume.

Abstract: A canister for use in administering reduced pressure to a tissue site includes a center body, a first end cap, and a second end cap. The center body includes a first end, second end, and a number of fluidly separate body conduits. The first end cap is connected to the first end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The first end has a port for receiving a conduit in fluid communication with the tissue site. The second end cap is connected to the second end of the center body and includes a number of return conduits fluidly connecting one body conduit to another. The second end cap has a port for receiving a conduit in fluid communication with a reduced pressure source. The fluid connection between the body conduits and the return conduits creates a continuous, tortuous pathway.
