Abstract: Systems, methods, and apparatus are provided for detecting leaks in systems for treating a patient with reduced pressure. In one instance, a system includes a distribution manifold for disposing proximate to the tissue site and a sealing member for disposing over the distribution manifold and at least a portion of intact epidermis of the patient. The sealing member has at least a portion that is substantially transparent. The system further includes a reduced-pressure source associated with the distribution manifold for providing reduced pressure to the distribution manifold and a leak-detection member sized and configured to substantially surround the distribution manifold. The leak-detection member includes a detection material that develops a color contrast when a portion is exposed to air and a portion is not exposed to air. The leak detection member works with even low flow systems. Other systems, methods, and apparatus are presented.

Abstract: Systems and methods for a reduced-pressure interface for providing reduced pressure through a sealing member to a distribution manifold includes a housing having a flange portion and a cavity wall portion such that the cavity wall portion forms a cavity having a tissue-facing cavity opening. A conduit port is coupled to the cavity wall and has a conduit aperture, such that the conduit port is adapted to receive a reduced-pressure delivery conduit. An attachment device is coupled to a tissue-facing side of the flange portion of the housing such that the attachment device couples the housing to the sealing member. Additionally, a cutting element is at least temporarily coupled to the housing proximate to the tissue-facing cavity opening such that the cutting element is adapted to form an aperture in the sealing member when the cutting element is driven into the sealing member with a driving force.

Abstract: A manually-actuated, constant reduced-pressure apparatus for use with a reduced-pressure system for treating tissue at a tissue site includes a flexible, collapsible member that is operable to move between a compressed position and an extended position. The collapsible member may be disposed between a carrier member and a slider member that move between a compressed position and an extended position. The carrier member and slider member are urged away from each other by a constant-force biasing member, e.g., a constant force coil spring. As the apparatus moves from the compressed position to the extended position, a constant reduced-pressure is generated and delivered to a reduced-pressure port. Methods of manufacturing a manually-actuated, constant reduced-pressure apparatus and methods of treating a tissue site are also provided.

Abstract: Manifold structures, systems, and methods are disclosed that include using longitudinal members and one or more shaped projections to cause microstrain at a tissue site. In one instance a manifold structure includes a plurality of spaced longitudinal members and at least one shaped projection coupled to at least one of the plurality of longitudinal members for creating a microstrain at a tissue site. The at least one shaped projection includes a columnar member having a distal end and includes an enlarged member positioned at the distal end of the columnar member. The columnar member has a first outer diameter (D1) and the enlarged member has a second outer diameter (D2). The second outer diameter of the enlarged member is greater than the first outer diameter of the columnar member (D2>D1). Other systems, methods, and structures are presented.

Abstract: A reduced pressure dressing for applying reduced pressure treatment to a tissue site includes an interface layer adapted to be positioned at the tissue site. An absorbent layer is in fluid communication with the interface layer to absorb liquid from at least one of the interface layer and the tissue site. A pump is in fluid communication with the absorbent layer to deliver a reduced pressure to the tissue site. A cover is positioned over the pump, the absorbent layer, and the interface layer to maintain the reduced pressure at the tissue site, and a liquid-air separator is positioned between the absorbent layer and the pump to inhibit liquid from entering the pump.

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 disc pump system includes a pump body having a substantially cylindrical shape defining a cavity for containing a fluid. The cavity having a resonant cavity frequency is formed by an internal sidewall and substantially closed at both ends by a first end wall and a driven end wall. The disc pump system includes an actuator that is driven a frequency (f) that corresponds to the fundamental resonant frequency of the actuator. The internal sidewall is configured to expand and contract in response to changes in temperature, thereby causing the actuator and cavity to have approximately the same resonant frequencies over a range of operating temperatures.
