An absorbent composite includes a porous base layer, a core layer, and a superabsorbent laminate layer. The core layer has a fluff pulp layer and superabsorbent polymer particles. The core layer is disposed on the base layer. The superabsorbent laminate layer is disposed on the core layer. The base layer, the core layer, and the superabsorbent laminate layer are compressed together and embossed under heat and pressure to form a plurality of embossed depressions. The embossed depressions are arranged across a major surface area of the superabsorbent laminate layer. The embossed depressions extend through the composite from the superabsorbent laminate layer and into the core layer and the base layer. A thin, soft, and pliable absorbent composite suitable for a variety of applications including wound care is thereby provided.

The present invention is directed to a hemostatic textile, comprising: a material comprising a combination of glass fibers and one or more secondary fibers selected from the group consisting of silk fibers; ceramic fibers; raw or regenerated bamboo fibers; cotton fibers; rayon fibers; linen fibers; ramie fibers; jute fibers; sisal fibers; flax fibers; soybean fibers; corn fibers; hemp fibers; lyocel fibers; wool; lactide and/or glycolide polymers; lactide/glycolide copolymers; silicate fibers; polyamide fibers; feldspar fibers; zeolite fibers, zeolite-containing fibers, acetate fibers; and combinations thereof; the hemostatic textile capable of activating hemostatic systems in the body when applied to a wound. Additional cofactors such as thrombin and hemostatic agents such as RL platelets, RL blood cells; fibrin, fibrinogen, and combinations thereof may also be incorporated into the textile. The invention is also directed to methods of producing the textile, and methods of using the textile to stop bleeding.

Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

Some embodiments have a pump assembly mounted to or supported by a dressing for reduced pressure wound therapy. The dressing can have visual pressure, saturation, and/or temperature sensors to provide a visual indication of the level of pressure, saturation, and/or temperature within the dressing. Additionally, the pump assembly can have a pressure sensor in communication with the flow pathway through the pump, and at least one switch or button supported by the housing, the at least one switch or button being accessible to a user and being in communication with the controller. The pump assembly can have a controller supported within or by the housing, the controller being configured to control an operation of the pump. The pump can be configured to be sterilized following the assembly of the pump such that all of the components of the pump have been sterilized.

An absorbent wound dressing (1) comprising a superabsorbent material (13) that is in fluid communication with the surface of a wound to which the dressing is applied when in use. The superabsorbent material (13) is enclosed in an envelope (14,15) having a wound-facing surface that is knitted or woven from a yarn comprising gelling fibres.

A conduit for treating a tissue site with reduced pressure may include a primary lumen and at least one secondary lumen. A wall of the conduit may include a first wall material and a second wall material. The first wall material may comprise a substantially non-absorbent material that is vapor impermeable and liquid impermeable. The second wall material may comprise an absorbent material that is vapor permeable and liquid impermeable. The second wall material may be positioned in fluid contact with the at least one secondary lumen. Other systems, apparatus, and methods are disclosed.

An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

An absorbent pad. A first side of the absorbent pad is configured to abut a patient at a fluid discharging area or other location. Discharging fluid passes through a fluid-permeable liner of the absorbent pad into absorbent material. Liquid may be placed in the absorbent material prior to placing it on a patient and heated or cooled. An overwrap may be wrapped around the patient to hold the hot or cold compress in place while absorbing discharging fluid from the patient. A fluid barrier at a second side of the absorbent pad, parallel with the first side, prevents liquid from passing out of the absorbent pad at the second side. A coupler having hooks is disposed on the second side of the absorbent pad and is configured to engage with fibers of the overwrap in order to secure the absorbent pad in place with respect to the patient and overwrap.

The present disclosure relates generally to tubular wound dressings that include a superabsorbent component that can be used to treat exuding wounds. The tubular wound dressings may include a superabsorbent component sandwiched between two tubular elastic and resilient components. Alternatively, the dressing may be concentrically arranged to include at least three components, including a superabsorbent component, and two elastic and resilient components. Also disclosed herein are kits including the tubular wound dressings of the present technology, and instructions for use.
