Abstract: In one example embodiment, an apparatus may include a panel with integrated fluid channels, wherein the panel and the fluid channel consist only of surfaces that can be manufactured with a straight-pull mold. A port may also be integrated into the panel to facilitate coupling the fluid channel to pneumatic components in an assembly. A seal may be secured to the panel over the fluid channel to form an integrated fluid conductor. The seal is preferably an adhesive label that can also be used for product labeling. Such an apparatus may be used in a control unit of a therapy system, employing several integrated fluid conductors. A method of manufacturing may include molding a panel, wherein the mold forms a channel integral to the panel. The panel and the channel preferably consist of surfaces that can be molded with a straight-pull mold.

Abstract: A method for calculating range of motion of a patient's jointed limb includes providing one or more locators at an upper limb of the jointed limb, and one or more of the locators at a lower limb of the jointed limb. A first image of the patient's joint in a fully extended position a second image of the patient's joint in a fully flexed position are captured with an imaging device. The method includes identifying positions of the locators of both the first image and the second image, and determining an extended angle of the patient's joint based on the identified positions of the locators of the first image. The method includes determining a flexed angle of the patient's joint based on the identified positions of the locators of the second image. The method includes determining a range of motion angle based on the extended angle and the flexed angle.

Abstract: In some examples, a dressing suitable for treating a tissue site may include a fluid management assembly including a fluid restraint configured to reduce a fluid capacity of the fluid management assembly proximate to the fluid restraint. Other features may be associated with the dressing including, by way of example and without limitation, abase layer, an adhesive, one or more wicking layers, and an absorbent layer. Other dressings, apparatus, systems, and methods are disclosed.

Abstract: A dressing for managing an incision and surrounding tissue where edema and swelling may be present post-operation. The dressing may maximize coverage of area in articulating joints, such as a knee or elbow, while allowing for substantial range of motion. In some embodiments, the dressing may comprise an adhesive border configured to be adhered to skin around an articulating joint, a skin-interfacing fabric for minimizing skin irritation, a foam body for manifolding negative pressure and absorbing exudate and other body fluids, and a thin polymer film cap for sealing the assembly so negative pressure can be maintained throughout the dressing.

Abstract: Some illustrative embodiments of an instillation assembly for treating a tissue site may include a fluid distribution lumen and a fluid hub that may define a fluid instillation pathway. The fluid distribution lumen may be defined by a first film layer and a second film layer, and the fluid hub may be positioned in fluid communication with the fluid distribution lumen. The instillation assembly may be used in combination with a reduced-pressure assembly that may define a reduced-pressure pathway separate from the fluid instillation pathway.

Abstract: A treatment system for applying negative pressure therapy and fluid instillation treatment to a tissue site, particularly an abdominal tissue site, is disclosed. In some embodiments, the treatment system may include a dressing member, a plurality of fluid removal pathways, a fluid instillation matrix, a drape, a negative-pressure source, and a fluid instillation source. Instillation fluid may be delivered from the fluid instillation source to the tissue site through the fluid instillation matrix, and negative pressure may be communicated and fluid withdrawn from the tissue site through the plurality of fluid removal pathways.

Abstract: A system for providing instillation fluid to a deep abdominal wound includes an instillation module and a connection structure. The instillation module defines a first surface and a second, abdominal contents-facing surface. The instillation module includes a distribution hub configured to receive instillation fluid from an instillation fluid source. The connection structure includes a first surface, a second, abdominal contents-facing surface; and a flow path extending between the first surface and the second surface. The flow path includes an inlet configured to receive an instillation fluid conduit engaged with the instillation fluid source and an outlet in fluid communication with the instillation module. The flow path defines an axis extending between the inlet and the outlet. The flow path is configured to compress in a direction defined by the axis.

Abstract: A device for generating skin grafts is disclosed, which includes a harvester having a distal end for placement on or in proximity of a portion of a subject's skin, where the harvester includes an orifice plate coupled to the distal end and having one or more openings. The device further includes a lid that is configured for attachment to the harvester to form a chamber and is configured for coupling to a vacuum source for generating a negative pressure in said chamber, thereby raising at least one blister through said at least one opening of the orifice plate. A skin-stretching mechanism is coupled to the harvester for stretching said skin portion so as to facilitate formation of said at least one blister. The harvester further includes a cutter integrated therein for cutting the blister. In some embodiments, the skin-stretching mechanism is coupled to the distal end of the harvester.
