Abstract: Systems and methods for treating a plurality of tissue sites include a multi-port therapy unit. The multi-port therapy unit includes a plurality of patient-side ports each fluidly coupled to a plurality of conduits and a fluid reservoir fluidly coupled to the plurality of ports. A plurality of pressure sensors are associated with the plurality of patient-side ports to determining a pressure associated with each conduit. A controller is operatively coupled to the plurality of pressure sensors to receive treatment pressure data, monitor pressure for each pressure sensor of the plurality of pressure sensors, and signal an alarm condition if the pressure is outside of a pre-selected range. The system includes a reduced-pressure source fluidly coupled to a dressing at each tissue site through the multi-port therapy unit.

Abstract: A fluid delivery system, method, and apparatus for providing instillation therapy with a negative-pressure source is described. The apparatus includes a housing having an ambient chamber and a negative-pressure chamber fluidly isolated from each other. The apparatus also includes a moveable barrier disposed in the housing between the ambient chamber and the negative-pressure chamber. The moveable barrier is operable to move between a charge position and a discharge position in response to negative pressure. A fluid source is disposed in the negative-pressure chamber and is collapsible in response to movement of the moveable barrier to the discharge position. The apparatus also includes a fluid outlet in fluid communication with the fluid source, a negative-pressure port in fluid communication with the negative-pressure chamber and configured to be coupled to a negative-pressure source, and a vent formed in the housing and fluidly coupled to the ambient chamber.

Abstract: As an example, in some embodiments is a dressing that may comprise a manifold, a bioresorbable component, and a degradation-modulating component. The degradation-modulating component may cover two or more surfaces of the bioresorbable component. The degradation-modulating component may be further configured to modulate degradation of the bioresorbable component.

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 treatment system for debriding a treatment area of a tissue site and applying negative pressure is disclosed. In some embodiments, the treatment system may include an ultrasonic bubble generator fluidly coupled to a negative-pressure source, fluid source, and a dressing. Fluid may be drawn from the fluid source to the ultrasonic bubble generator, whereby micro-bubbles and ultrasonic waves may be generated in the fluid before the fluid is instilled to the dressing.

Abstract: Dressings for treating a tissue site with negative pressure are disclosed, which may include a dressing having at least three layers assembled in a stacked relationship. In one example embodiment, a first film may comprise a non-porous material and a plurality of fluid restrictions. A first manifold layer may be adjacent to the first film and may comprise a second film of a transparent material having blisters and a manifold area. The first manifold layer may further comprise apertures configured to allow fluid transfer through the second film. A second manifold layer may be adjacent to the first manifold layer and may comprise foam having a contact area that is less than the manifold area of the first manifold layer.

Abstract: This disclosure describes devices, systems, and methods related to a connector for a dressing, such as a dressing of a hyperbaric oxygen therapy system. An example of a connector includes a connector body configured to define at least a portion of a first channel. The connector also includes a viewing member coupled to the connector body. The connector further includes a deformable member positioned within the first channel. The deformable member is configured to deform based on a pressure associated with the deformable member and to provide a visual indication, via the viewing member, of the pressure.

Abstract: A reduced pressure tissue treatment system includes an applicator having an aperture, a first pad section, and a second pad section substantially covering the aperture and positioned substantially adjacent the first pad section. A fabric layer is located at least partially between the second pad section and the drape, and the fabric layer includes a woven or non-woven fabric made from a fiber material. A drape substantially covers the first pad section, the second pad section, the fabric layer, and the applicator. A reduced pressure source is in fluid communication with at least one of the first pad section and the fabric layer for providing reduced pressure to the aperture.

Abstract: A system and method for performing tissue therapy may include applying a reduced pressure to a tissue site of a patient. A fluid parameter associated with applying a reduced pressure to the tissue site may be sensed. An audible fluid leak location sound may be generated in response to sensing the fluid parameter. The audible fluid leak location sound may be altered in response to sensing that the fluid parameter changes. By altering the audible fluid leak location sound in response to sensing a change of the fluid parameter, a clinician may detect location of a fluid leak at the drape by applying force to the drape. The force applied to the drape may be a clinician pressing a finger onto an edge of the drape.
