Abstract:
The illustrative embodiments described herein are directed to a system and method for administering reduced pressure at a tissue site. The apparatus includes a reduced pressure source. The reduced pressure source generates a reduced pressure. The apparatus includes a tube having a plurality of lumens. The plurality of lumens includes at least one collection lumen. The reduced pressure source applies the reduced pressure to the tissue site through the plurality of lumens such that the at least one collection lumen receives fluid from the tissue site. The at least one collection lumen stores the fluid received from the tissue site.
Abstract:
A connectable component module for a reduced pressure treatment system is provided. The module includes a housing with a rim, a recessed end surface, and an extension. A mounting assembly is fixed to the recessed end surface and includes extendable latches. The latches include a fastener bar that is flush with the rim when the latches are not extended. The module also generally includes a control system contained within the housing. The control system has a communication controller, a communication plug coupled to the communication controller and protruding through an aperture in the mounting assembly and recessed end, and a communication port coupled to the communication controller and exposed to an aperture in the extension.
Abstract:
A reduced pressure delivery system for applying a reduced pressure to a tissue site is provided. The system includes a manifold having a plurality of flow channels. The manifold is configured to be placed adjacent the tissue site. A first conduit is in fluid communication with the flow channels of the manifold to deliver a reduced pressure to the flow channels. A second conduit is in fluid communication with the flow channels of the manifold and is operably connected to a valve. The valve selectively purges the second conduit with ambient air when the valve is positioned in an open position, and a controller is operably connected to the valve to place the valve in the open position for a selected amount of time at a selected interval during delivery of reduced pressure through the first conduit.
Abstract:
A reduced pressure treatment system is provided that includes a canister that is fluidly connected to a tissue site and is configured to receive fluid drawn from the tissue site under the influence of a reduced pressure. A reduced pressure source provides the reduced pressure and is fluidly connected to the tissue site by a fluid communication path, which may include a source conduit, the canister, and a target conduit. A sensing device communicates with the source conduit and is configured to sense a pressure in the source conduit. A valve communicates with the source conduit and is configured to vent the reduced pressure. A processing unit communicates with the sensing device and the valve and is configured to open the valve for a selected amount of time, determine a decay of reduced pressure, and determine a fill status of the canister based on the decay of reduced pressure.
Abstract:
A tissue treatment system including a processing unit executing software, an electronic display in communication with the processing unit, and a storage unit in communication with the processing unit. The software may be configured to cause the processing unit to manage a patient history database, treatment history database, and image history database. The processing unit may further be configured to enable a clinician to access and display information stored in any of the databases.
Abstract:
In one example embodiment, a dressing connector is described that provides a first fluid path between a first connector and a second connector, and a second fluid path between a third connector and a fourth connector. A liquid barrier may be disposed in the first fluid path. The first fluid path and the second fluid path are generally exposed to an exterior surface of the dressing connector. In some embodiments, a tube may also be bonded to the third connector to provide a third fluid path between the dressing connector and another component. In more particular embodiments, the liquid barrier may be a filter, such as a hydrophobic bacterial filter, a sintered polymer filter, and/or a charcoal filter.
Abstract:
Dressings, systems, and methods are disclosed that, in some embodiments, relate to treating a tissue site. In one embodiment, a dressing may include a manifold, a retention pouch, a sealing member, and a conduit interface. The manifold may be adapted to distribute reduced pressure to the tissue site, and the retention pouch may be adapted to retain and manage fluid extracted from the tissue site. The sealing member may cover the retention pouch and the manifold to provide a sealed space with the tissue site. The conduit interface may be in fluid communication with the sealed space and an exterior surface of the sealing member. The dressing may be utilized with a therapy device operable to control reduced pressure in the dressing and fluid flow over the sealing member.
Abstract:
A disc pump valve (10) for controlling the flow of fluid through a disc pump includes a first plate (16) having first plate apertures (20) and a second plate (14) having second plate apertures (18) both extending generally perpendicular through the first plate (16) and the second plate (14), respectively. The second plate apertures (18) are substantially offset from the first plate apertures (20). The disc pump valve (10) also includes a sidewall (11) disposed between the first plate (16) and second plate (14). A valve flap (17) is disposed and moveable between the first plate (16) and second plate (14). The valve flap (17) includes flap apertures (22) substantially offset from the first plate apertures (20) and substantially aligned with the second plate apertures (18), and low-mass areas (21). The low-mass areas (21) are offset from the first plate apertures (20) and second plate apertures (18). The valve flap (17) moves between the first plate (16) and second plate (14) in response to a change in direction of differential pressure of the fluid outside the disc pump valve (10).
Abstract:
A two-cavity pump (10) has a side wall (22) closed by two end walls (12,19) for containing a fluid. An actuator (40) is disposed between the two end walls (12,19) and functions as a portion of a common end wall (21) of the two cavities (16,23). The actuator (40) causes an oscillatory motion of the common end wall (21) to generate radial pressure oscillations of the fluid within both cavities (16,23). An isolator (30) flexibly supports the actuator (40). The first cavity (16) includes the single valve (35) disposed in one of a first and second apertures (25,27) in the end wall (12) to enable fluid flow in one direction. The second cavity (23) includes the bidirectional valve (36) disposed in one of a third and fourth apertures (26,28) in the end wall (19) to enable fluid flow in both directions.
Abstract:
Systems, methods for manufacturing, 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.
