The invention relates to slit absorbent articles and the use of slits in absorbent materials to provide improved liquid intake rate, flexibility and softness compared to the unmodified material. The absorbent material, including superabsorbent materials, are particularly useful as absorbent cores in disposable absorbent articles such as diapers, incontinent products, sanitary napkins and the like.

An apparatus, system, and method for closing an opening through a surface of a tissue site is described. The apparatus includes an apposition layer adapted to be positioned over the opening. The apposition layer is formed from a material having a firmness factor, and has a plurality of holes extending through the apposition layer. The holes form a void space and have a perforation shape factor and a strut angle configured to collapse the apposition layer in a first direction relative to a second direction. A sheet having a plurality of perforations is configured to surround the apposition layer, the sheet having a plurality of perforations. The apposition layer generates a closing force in the first direction that is substantially parallel to the surface of the tissue site to close the opening in response to application of a negative pressure.

Dressings for tissue treatment with negative pressure and methods of using the dressings for tissue treatment with negative pressure, which may comprise a dressing having at least three layers assembled in a stacked relationship. The first layer may comprise or consist essentially of a polymer film having a plurality of fluid restrictions that are normally unstrained or closed. The second layer may comprise a manifold, and the third layer may comprise or consist essentially of a polymer drape. A fourth layer, which may be coupled to the first layer opposite the second layer, may comprise or consist essentially of a silicone gel having a plurality of apertures. In some examples, the plurality of apertures in the fourth layer may be registered with the fluid restrictions of the first layer.

A dressing may comprise a manifold having a first planar surface and a second planar surface opposite the first planar surface, and a first layer adjacent to the first planar surface and a second layer adjacent to the second planar surface. The first layer and the second layer may be laminated to the first planar surface and the second planar surface, respectively. Pressure-responsive fluid restrictions through at least one of the first layer and the second layer may be adjacent to the manifold. The first layer and the second layer may also form a sleeve or an envelope around the manifold in some embodiments. At least one of the first layer and the second layer may be configured to be disposed between the manifold and a tissue site in use. In some examples, the dressing may have a smooth or matte surface configured to contact a tissue site.

A three-dimensional film for use as a transfer layer in an absorbent article has a continuous surface and a discontinuous surface disposed generally parallel to and spaced from said continuous surface; both the continuous surface and the discontinuous surface have large scale apertures defined by sidewalls originating on the surface and extending outwardly therefrom and sized to permit acquisition of fluids by gravity, and optionally each surface also includes small scale apertures sized to acquire fluids by capillary action.

An activated composite web includes a nonwoven layer, and a formed film layer attached to the nonwoven layer. The formed film layer includes a plurality of first apertured protuberances having a mesh count of at least 35, and a plurality of second apertured protuberances. Each of the second apertured protuberances has a cross-sectional area larger than each of the first apertured protuberances. A plurality of first lanes are aligned in a first direction and have a first width extending in a second direction substantially perpendicular to the first direction. The first apertured protuberances are located in the first lanes. A plurality of second lanes are aligned in the first direction and have a second width, less than the first width, extending in the second direction. The first lanes and the second lanes alternate with each other in the second direction. The second apertured protuberances are located in the second lanes.

An absorbent article for personal hygiene is disclosed with an absorbent core sealed between a liquid impermeable garment-side liner and a liquid permeable body-side cover together with an attached bacterial isolation pad, consisting of an absorbent layer sealed between an extension of the liquid impermeable garment-side liner and a liquid permeable topsheet which can be positioned to overlay the anal region of the body-side cover. A detachable bacterial isolation pad from the absorbent article and from the body-side cover is provided. Hygienic gripping tabs at the front-facing end of the absorbent article and at the rear-facing end of the bacterial isolation pad allow sanitary handling during removal of a soiled article.

An absorbent article (10;100;200) includes a topsheet layer (16,17), a backsheet layer (18) and a subjacent layer (20, 20A-20D) between the topsheet layer (16,17) and the backsheet layer (18). A compressible fluid management layer (22;110;210) is positioned between the topsheet layer (16,17) and the subjacent layer (20, 20A-20D). The compressible fluid management layer (22;110;210) has an inner edge (22A) that defines an annular opening (28), with the annular opening (28) extending entirely through the compressible fluid management layer (22;110;210). The compressible fluid management layer (22;110;210) includes a first embossed feature (24) positioned at least at portions, within the annular opening (28), and adjacent to the inner edge (22A) of compressible fluid management layer (22;110;210), shaped to conform the shape of the inner edge (22A). A first embossed feature (24) is positioned within the topsheet layer (16,17) and the subjacent layer (20, 20A-20D). The absorbent article (10;100;200) also includes a second embossed feature (26) positioned lateral to the peripheral edges (31,33) of the compressible fluid management layer (22;110;210).
