Abstract: A disc pump system includes a pump body having a substantially cylindrical shape defining a cavity for containing a fluid, the cavity being formed by a side wall closed at both ends by substantially circular end walls, at least one of the end walls being a driven end wall. The system includes an actuator operatively associated with the driven end wall to cause an oscillatory motion of the driven end wall and an isolator is operatively associated with the peripheral portion of the driven end wall to reduce dampening of the displacement oscillations. The isolator comprises a flexible printed circuit material that includes a strain gauge. The strain gauge measures data that may be used to determine the amount of pressure provided by the pump.

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 (J) 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.

Abstract: Systems, methods, and dressing are presented for treating a tunnel wound on a patient. In one instance, a reduced-pressure, tunnel-wound dressing (102) includes a longitudinal core member (118) formed from a closed-cell foam that is surrounded by a first longitudinal concentric member (120) formed from a manifolding material. When subjected to reduced pressure, the longitudinal core member expands and the first longitudinal concentric member compresses. These actions create intimate contact between the tunnel wound and the dressing, oppose collapse of the tunnel, and when reduced pressure is removed provide clearance to remove the dressing. Other embodiments are presented.

Abstract: A disc pump includes an elliptical pump base (110) having at least one aperture (125) extending through the pump base (110). The pump base (110) comprises a first end wall (111) and a sealing surface (121). The disc pump includes an isolator (150) overlying the pump base (110) and having an isolator valve aperture (155) extending through the isolator (150) at or near the periphery of the isolator (150) and partially overlying a cavity (115) formed by the pump base (110) to form an outlet. In addition, the disc pump includes a valve flap (130) disposed between the pump base (110) and the isolator (150). The valve flap (130) has apertures (533) arranged about its periphery, beyond the periphery of the cavity (115) but underlying an isolator valve aperture (155). The valve flap (130) seals against the sealing surface (121) to close the pump outlet and prevent fluid from flowing from the outlet into the cavity (115) and flexes away from the sealing surface (121) to allow fluid to pass from the cavity (115) through the pump outlet.

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: A reduced-pressure medical treatment system for treating a tissue site on a patient includes a medical drape that has an holographically-formed polymer dispersed liquid crystal (H-PDLC) device that changes visual appearance when experiencing strain. The change in visual appearance of the H-PDLC device allows identification of the existence of strain and may allow a quantitative assessment of the range of stress involved. In other aspects, a dressing conduit connector, canister, and reduced-pressure interface use a holographically-formed polymer dispersed liquid crystal (H-PDLC) device to help determine the existence and perhaps the amount of stress experienced. Other systems, methods, and devices are presented.
