A dressing for treating a tissue site with negative pressure, having an integrated sensor comprising a force or load measurement sensor. The sensor may telemeter to a therapy system the deformation of the dressing as the dressing is pushed into the tissue site during the application of negative pressure to the tissue site. The sensor may measure the force that is applied to the dressing. Measurements of the force applied to the dressing may be taken using the sensor on a periodic basis during negative-pressure therapy to enable monitoring of the fill level of the tissue site as granulation tissue fills the tissue site. Monitoring of the force applied to the tissue site over the course of negative-pressure therapy may assist a clinician in making decisions on how to manage and treat the patient, as well as providing confirmatory data about the efficacy of the therapy.

In another aspect a two-piece dressing includes a drape and a pad. The pad is configured to be coupled to the drape and to a light source, and the pad includes a light switchable adhesive configured to couple the pad to the drape.

A first check valve may be fluidly coupled to the absorbent and the blister and configured to prevent fluid flow from the blister into the absorbent if the blister is moved from the expanded position to the collapsed position. A second check valve may be fluidly coupled to the blister and the ambient environment and configured to prevent fluid flow from the ambient environment into the blister if the blister is moved from the collapsed position to the expanded position.

Low acuity dressing with integral pump

Systems, apparatuses, and methods for providing negative pressure with 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, a system may comprise a tissue interface adapted to be coupled to a source of instillation fluid and a dressing interface having a therapy cavity that includes a pH sensor to provide data indicative of acidity/alkalinity at the tissue site. Such apparatus may further comprise algorithms for processing such data for providing information relating to the progression of healing of wounds at the tissue site.

Systems and methods for controlling fluid instillation therapy using pH feedback

An apparatus for conducting fluid may comprise a first layer, a second layer, and a third layer sealed to form a first fluid pathway and a second fluid pathway in a stacked relationship. An aperture may be disposed at a first end of the second fluid pathway. Upon the application of a negative pressure, fluid may be drawn through the third aperture, into the second fluid pathway, and through the first fluid pathway. The apparatus may be fluidly coupled to a dressing at a tissue site. At least a portion of the third layer may be configured to allow moisture to evaporate from a periwound into the second fluid pathway. The fluid drawn through the third aperture may aid in removal of the evaporated moisture within the second fluid pathway, as well as moisture directly from the periwound, to reduce the risk of maceration to the periwound.

Low-profile fluid conductors with moisture management features

This disclosure describes devices, systems, and methods related to dual switchable adhesives, the manufacture thereof, and the use thereof. An exemplary dual switchable adhesive includes one or more polymers, photo initiators configured to cause the one or more polymers to cross-link responsive to receiving light, and polymerization initiators configured to cause the one or more polymers to cross-link responsive to receiving moisture.

In some examples, a dressing suitable for treating a tissue site may include a sealing member configured to form a sealed enclosure relative to the tissue site. A fluid buffer may be configured to be positioned at a sealing member aperture in fluid communication between the sealed enclosure and an ambient environment external to the sealed enclosure. Other dressings, apparatus, systems, and methods are disclosed.

Dressing including outlet connection fluid buffer

Systems, methods, and apparatuses for debriding a tissue site are described. The system includes a manifold and a cover adapted to form a sealed space over the tissue site for providing negative pressure. The system also includes a debridement tool positioned between the manifold and the tissue site. The debridement tool having a tissue-facing surface and a plurality of holes separated from each other by walls. The walls have transverse surfaces extending between the tissue-facing surface and an opposite surface that form cutting edges. The holes have a perforation shape factor that allows the holes to collapse from a relaxed position to a contracted position in response to the application and removal of negative pressure from the sealed space. The cutting edges debride the tissue site in response to movement between the relaxed position and the contracted position.
