Abstract: A citric acid containing dressing for treating a tissue site with negative pressure may comprise a cover, a manifold, and a perforated polymer film and/or a sealing layer. The sealing layer can be a perforated silicone gel having a treatment aperture. The dressing can further contain an adhesive. The cover, the manifold, and the perforated polymer film and/or the sealing layer may be assembled in a stacked relationship with the cover and the sealing layer enclosing the manifold. Citric acid may be present on or incorporated in, for example, the perforated polymer film and/or the sealing layer.

Abstract: An evaporative bridge dressing that may be used with negative-pressure treatment of tissue. The evaporative bridge dressing may have one or more fluid transfer layers comprised of high-density wicking material enclosed between layers of film having high moisture-vapor transfer rates to manage liquid storage and pressure drop. The evaporative bridge may have an absorbent in some embodiments. An evaporation channel may be disposed adjacent to or combined with the evaporative bridge. A means for measuring pressure across the evaporative bridge may include a feedback path. A support means may reduce or prevent collapse of one or more of the evaporative bridge, the evaporation channel, the feedback path.

Abstract: Systems, apparatuses, and methods for providing negative pressure and/or instillation fluids to a tissue site are disclosed. Some embodiments are illustrative of an apparatus or system for delivering negative-pressure and/or therapeutic solution of fluids to a tissue site, which can be used in conjunction with sensing properties of fluids extracted from a tissue site and/or instilled at a tissue site. For example, an apparatus may comprise a dressing interface or connector that includes a pH sensor, a humidity sensor, a temperature sensor and/or a pressure sensor embodied on a single pad within the connector and proximate the tissue site to provide data indicative of acidity, humidity, temperature and pressure. Such apparatus may further comprise algorithms for processing such data for detecting leakage and blockage as well as providing information relating to the progression of healing of wounds at the tissue site. An illustrative method may comprise positioning a dressing interface having a pH sensor, a temperature sensor, a humidity sensor, and a pressure sensor at a tissue site, and applying reduced pressure to the dressing interface to draw fluids from the tissue interface in contact with the sensors to sense the pH, temperature, humidity, and pressure properties of the fluids flowing from the tissue site. The method may further comprise providing fluid data indicative of such properties to a control device for processing the fluid data and transmitting the data to another component in the system.

Abstract: An apparatus for treating a tissue site includes a dressing, an oxygen source, a valve, and a negative-pressure source. The dressing is configured to be sealed around the tissue site. The oxygen source is fluidly coupled to the dressing and configured to provide a low flow of oxygen. A first port of the valve is fluidly coupled to the dressing and the valve moves between a closed position preventing flow through the valve and an open position permitting flow through the valve. The negative-pressure source is fluidly coupled to a second port of the valve and provides negative pressure to the second port of the valve at a non-therapeutic level. The valve separates the negative-pressure source from the dressing and selectively opens when a positive pressure is applied on an upstream side of the valve.

Abstract: A method may include forming a mesh comprising a plurality of strands meshed together. Each of the plurality of strands may include a polymeric film. The method may include perforating the mesh to form a perforated mesh having one or more perforations. The method may further include texturing the perforated mesh to form at textured and perforated mesh having at least one of a dimple or a channel. A system may include a cover configured to form a seal over the tissue site. The system may also include a reduced-pressure source configured to provide reduced pressure through the cover at the tissue site. The system may further include a tissue interface configured to be disposed underneath the cover at the tissue site. The tissue interface may include a textured mat having a plurality of strands of polymeric film matted together and at least one of a dimple or a channel.
