    摘要: A releasable medical drape, and systems and methods having the same, includes at least a liquid-impermeable, vapor-permeable layer, a pressure-sensitive adhesive layer, and a soft-gel layer having a plurality of apertures. The soft-gel layer is configured to be disposed adjacent to a tissue site. A portion of the pressure-sensitive adhesive layer extends through the plurality of apertures in the soft-gel layer to contact the tissue site. The soft-gel layer forms a good seal with the tissue site and the pressure-sensitive adhesive layer extending through the plurality of apertures forms a firm—but releasable—coupling with the tissue site.

    摘要: In some embodiments, a dressing assembly may include a dressing bolster, an interface seal, and a base layer. The dressing bolster may include a first side, a second side, and a periphery. The interface seal may be coupled at the periphery of the dressing bolster. The base layer may include a base layer flange configured to be coupled to the dressing and to extend beyond the periphery of the dressing bolster. The dressing assembly may be suitable for treating a tissue site with reduced pressure and for creating an apposition force between a first portion of the tissue site and a second portion of the tissue site. Other systems, apparatus, and methods are disclosed.

    摘要: An apparatus (1) for negative pressure wound therapy comprises a source of reduced pressure (10) and first (22a) and second (26a) chambers, the first chamber being in fluid communication with the source of reduced pressure such that a negative pressure may be generated in the first chamber, the negative pressure being prevented from exceeding a predetermined value by way of a pressure release means (30), and the second chamber comprising means (28) for establishing a fluid connection with a wound. A valve (24) between the first and second chambers permits the negative pressure in the second chamber to increase in response to an increase in the negative pressure in the first chamber and prevents the negative pressure in the second chamber from dropping in response to a drop in the negative pressure in the first chamber.

    摘要: A system for applying negative pressure to a joint positioned in a treatment area. The system includes a negative pressure dressing. The negative pressure dressing includes a compressive layer and a sealing layer. The compressive layer includes a first surface and a second, treatment area-facing. The compressive layer further includes a first elongated portion configured to be positioned proximate the joint. The first elongated portion includes a first end and a second end. The compressive layer further includes a second elongated portion spaced from the first elongated portion and configured to be positioned proximate the joint. The second elongated portion includes a first end and a second end. The compressive layer further includes an interconnecting portion extending between the first elongated portion and the second elongated portion. The interconnecting portion is configured to overlie at least a portion of the joint. The compressive layer further includes a plurality of channels formed in the first surface and extending proximate the second surface. The plurality of channels is formed in at least one of the first end and the second end of the first elongated portion and at least one of the first end and the second end of the second elongated portion. The sealing layer is configured to form a seal around a perimeter of the negative pressure dressing.

    摘要: Systems, apparatuses, and methods for providing negative pressure to a tissue site are disclosed. Illustrative embodiments may include an apparatus or system for delivering negative-pressure to a tissue site, which can be used in conjunction with low-profile distribution components for wound therapy. Such apparatus may include a low-profile dressing interface or connector comprising at least two side-by-side fluid pathways fluidly coupled to a recessed space of the connector, one for providing negative pressure to a tissue interface or manifold and the other for sensing the negative pressure within the recessed space adjacent the tissue interface. In some embodiments, for example, the apparatus may comprise a first layer of polymeric film having an outer surface, an inner surface, and a plurality of features extending from the inner surface, and a second layer of polymeric film coupled to the first layer. The second layer may have an outer, tissue-facing surface and an inner surface coupled to the first layer and covering the plurality of features to form an enclosed space with the inner surface of the first layer and a plurality of flow channels within the enclosed space. The second layer also includes an aperture defining the recessed space adapted to fluidly coupling the enclosed space to the tissue interface.
