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 processing element for processing the fluid data, and transmitting the data to another component in the system.

Abstract: A dressing assembly for use with a reduced pressure treatment system, the dressing assembly develops a directed force under reduced pressure. The directed force may be a radial force or a closing force. The dressing assembly includes a shaped dressing bolster having a shaped extremity that is operable to evenly deliver the radial force and to distribute reduced pressure. Numerous shapes may be used for the shaped extremity. The dressing assembly may further include an over-drape to assist in creating a seal over the shaped dressing bolster and against a portion of a patient's epidermis.

Abstract: A dressing for treating a tissue site, particularly a peritoneal or abdominal site, is disclosed. The dressing may comprise: a substrate; an adherent layer coupled to a surface of the substrate; and a fibrous layer comprising fibers coupled to a surface of the adherent layer opposite the substrate. Typically, the fibrous layer satisfies one or more of the following: at least 75% of the fibers are coupled approximately perpendicular to the surface of the substrate; at least 95% of the fibers in the fibrous layer have a length to diameter aspect ratio from about 10 to about 1000; and no more than 10% of the fibers are coupled approximately tangential to the surface of the substrate. Optionally, the fibrous layer may be formed by a flocking process. Methods of treating various tissue sites using the dressings and negative-pressure therapy are also disclosed.

Abstract: A system for providing reduced-pressure treatment to a moveable tissue site, such as a joint, includes a flexible dressing bolster. The flexible dressing bolster has a first side and a second, inward-facing side, and a plurality of flexion joints formed on the flexible dressing bolster. The system further includes a sealing subsystem for providing a fluid seal over the flexible dressing bolster and the patient's epidermis and a reduced-pressure subsystem for delivering a reduced pressure to the sealing subsystem. The sealing subsystem and reduced-pressure subsystem are operable to deliver a reduced pressure to the moveable tissue site. The flexible dressing bolster is operable to allow articulation or movement of the moveable tissue site. The sealing subsystem may include a drape with folds. Other systems, apparatuses, and methods are presented.

Abstract: Dressings, systems, and methods are disclosed, in some embodiments, that involve treating a tissue site with reduced pressure, wherein the dressing includes a dressing reduced-pressure indicator that allows one to ascertain that the reduced pressure applied at the dressing is greater than a threshold reduced pressure. The dressing reduced-pressure indicator may include a moving member that is adapted to move under reduced pressure and a visual indicator associated with the moving member. Another embodiment uses an electro-mechanical indicator to provide a powered visual alert or audible alert or another output signal. Other dressings, systems, and methods are disclosed.

Abstract: This disclosure describes devices, systems, and methods related to therapy devices including pumps that are operable in multiple operating modes. An exemplary wound therapy device includes a pump configured to be worn by a user and a controller coupled to the pump and configured to transition the pump from operating in a first operating mode to operating in a second operating mode responsive to a pressure of the wound therapy device satisfying a first pressure threshold. The first operating mode is associated with a first drive voltage that is different from a second drive voltage associated with the second operating mode.
