Abstract: A system, method, and apparatus for treating a tissue site with reduced pressure includes a dressing adapted to be positioned proximate the tissue site. An absorbent may be adapted to be fluidly coupled to the manifold, and an ion exchange member may be adapted to be fluidly coupled between the manifold and the absorbent. A sealing member may be adapted to cover the tissue site to form a sealed space having the manifold disposed therein. A reduced-pressure source may be adapted to be fluidly coupled to the manifold.

Abstract: Sealing members and methods of manufacturing the same are described. A first film layer and a second film layer each having a first side and a second side can be provided. A first adhesive can be coupled to the second side of the first film layer to form a first adhesive layer. A second adhesive can be coupled to the second side of the second film layer to form a second adhesive layer, and a third adhesive can be coupled to the first side of the second film layer to form a third adhesive layer. One or more perforations can be formed through the third adhesive layer, the second film layer, and the second adhesive layer. A first side of the third adhesive layer can be coupled to a second side of the first adhesive layer.

Abstract: A system that may be adapted to distribute reduced pressure to a tissue site may include a dressing and a sealing member. The dressing may include a manifold layer, a storage layer, and a plurality of retainers. The manifold layer may be adapted to be positioned proximate the tissue site, and the storage layer may be positioned proximate the manifold layer. The plurality of retainers may be disposed in the storage layer. Each of the retainers may define a fluid communication channel through the storage layer. The retainers may be adapted to substantially preclude deformation of the storage layer into the fluid communication channels. The sealing member may be adapted to cover the dressing and to provide a fluid seal between the sealing member and the tissue site.

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: Some illustrative embodiments of a dressing for treating a tissue site may include a fluid hub, a plurality of elongate fluid members, and a separable joint. The plurality of elongate fluid members may be positioned in fluid communication with the fluid hub. Each of the plurality of elongate fluid members may include a proximal end, a distal end, and an elongate side between the proximal end and the distal end. The elongate side of the elongate fluid members may extend longitudinally outward from the fluid hub. The separable joint may be coupled between the elongate side of one of the plurality of elongate fluid members and the elongate side of another of the plurality of elongate fluid members. Other dressings, systems, and methods are disclosed.

Abstract: A system for treating a tissue site includes a pressure source to apply reduced pressure, and a manifold in fluid communication with the pressure source to provide reduced pressure to the tissue site. The system includes a drape for adhering to the tissue site to cover the tissue site and the manifold. The drape has a film layer having a thickness less than about 15 microns, and an adhesive coupled to the film layer. The adhesive seals the film layer to the tissue site to create a sealed space having the manifold therein. The adhesive is sufficiently thick to limit leaks between the film layer and the tissue site.

Abstract: A negative pressure wound therapy system includes at least one sensor coupled to a wound dressing for a wound of a patient, and a control circuit. The at least one sensor is configured to output an indication of a displacement of the wound dressing. The control circuit is configured to receive the indication of the displacement of the wound dressing, calculate a therapy parameter corresponding to the indication of the displacement, and output the therapy parameter.

Abstract: A system for providing a force to a desired area on a curved body part of a person includes a dressing assembly shaped and configured to be placed on the desired area of the person, a releaseable circumferential member surrounding the curved body part that holds the dressing assembly against the desired area, a sealing subsystem for providing a fluid seal over the dressing assembly and the person's skin, and a reduced-pressure subsystem for providing a reduced pressure to the dressing assembly. When reduced pressure is supplied, the system generates the force against the desired area on the curved body part.

Abstract: A reduced-pressure treatment system for applying reduced pressure to a tissue site at a limited-access location on a patient includes a reduced-pressure source, a treatment manifold for placing proximate the tissue site and operable to distribute reduced pressure to the tissue site, and a sealing member for placing over the tissue site and operable to form a pneumatic seal over the tissue site. The reduced-pressure treatment system also includes a reduced-pressure bridge and a moisture-removing device on at least portion of the reduced-pressure bridge. The reduced-pressure bridge includes a delivery manifold operable to transfer the reduced pressure to the treatment manifold, an encapsulating envelope at least partially enclosing the delivery manifold and having a patient-facing side, and a reduced-pressure-interface site formed proximate one end of the reduced-pressure bridge.
