摘要： A dressing includes a manifold layer and a drape coupled to the manifold layer and configured to seal the manifold layer over a wound. The drape has an opening extending therethrough. A connection pad is positioned at the opening and configured to couple the dressing to a tube. The connection pad includes an outer ring coupled to the drape and a center dimple extending away from the drape and defining a volume between the center dimple and a plane defined by the outer ring. The dressing also includes an absorbent manifolding structure positioned between the center dimple and the manifold layer and formed to substantially match a shape of the volume.

摘要： A therapy system for treating a tissue site with negative-pressure therapy and/or fluid instillation therapy in response to information received from a diagnostic module is disclosed. In some embodiments, the therapy system may include a dressing, a negative-pressure source, a container, and a diagnostic module. The dressing may be adapted to be placed on the tissue site, and the negative-pressure source may be adapted to be fluidly coupled to the dressing. The container may be adapted to be fluidly coupled to the dressing and to the negative-pressure source and to receive fluid from the tissue site. The diagnostic module may be adapted to be exposed to gas associated with the fluid from the tissue site. The diagnostic module may comprise a sensor configured to detect a condition of the tissue site and to generate an output based on the detected condition. The sensor may be configured to detect a volatile organic compound. In some embodiments, the diagnostic module may be positioned on the container.

摘要： A dressing or a tissue interface for treating a tissue site with negative pressure may comprise a fluid control layer, a base manifold, and a closure manifold layer. The fluid control layer may comprise a plurality of fluid restrictions, and the base manifold may be disposed adjacent to the fluid restrictions. The closure manifold may have perforations adjacent to the base manifold layer. Additionally, the base manifold layer may have a first density, and the closure manifold layer may have a second density, wherein the second density is less than the first density. The closure manifold may be configured to deform laterally at a second negative pressure that is less than the first negative pressure.

摘要： Tissue dressing materials and associated methods of forming such dressing materials are disclosed. In one example embodiment, a dressing material may include a foam and a film formed on a first side of the foam. The film may be integrally-formed on the side of the foam. The film may include a plurality of apertures. A method of making the dressing material may include placing a pre-polymer mixture and water into a mold to create the dressing material comprising a foam and an integral film on at least one surface of the foam. The method may further include forming a plurality of openings in at least the integral film, with the openings being formed within the mold or subsequent to removal of the dressing material from the mold.

摘要： A dressing for treating a tissue site with negative pressure may comprise a first polymer film having a plurality of fluid restrictions, and a second polymer film comprising a plurality of standoffs disposed adjacent to the first polymer film. The first polymer film and the second polymer film may be substantially transparent to allow observation of the tissue site. In some embodiments, at least some of the standoffs may be offset from the fluid restrictions. The second polymer film may comprise fluid passages adjacent to the standoffs in some examples.

摘要： This disclosure describes devices, systems, and methods related to a wound closure device. An example of a wound closure device includes a plurality of base members configured to adhere to a tissue site and one or more attachment members for use in combination to create mechanical tension on the edges of a wound to facilitate closure of the wound. The plurality of base members include a first base member that includes light switchable adhesive. The light switchable adhesive is configured to transition from a first state to a second state, and the light switchable adhesive has a first peel strength in the first state that is greater than a second peel strength of the light switchable in the second state. The one or more attachment members are configured to couple to two or more base members of the plurality of base members.

摘要： 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 an ambient port for providing the pressure sensor and the humidity sensor with access to the ambient environment providing readings relative to the atmospheric pressure and humidity.
