The present invention relates to a sponge dressing for treating wounds comprised of a polymer sponge containing a plurality of antimicrobial dyes with at least one dye being gram positive and at least one other dye being gram negative and a silicon adhesive secured to a sponge surface. The sponge dressing can be exposed initially to gamma radiation and later sterilized by ethylene oxide or alternatively it can be sterilized by ethylene oxide and later irradiated by gamma radiation. The sponge dressing has a morphology characterized by an average pore throat diameter of 0.5-500 μm and a porosity ranging from about 60% to about 99.5%. The sponge dressing can also contain at least one biofilm reducing agent, at least one chelating agent and an ionic and non-ionic surfactant.

Provided is a hemostatic dressing. The hemostatic dressing includes: a porous matrix layer including a biocompatible polymer; a hemostatic layer loaded on the porous matrix layer and including a polymer in which polyhydric phenol-containing moieties are introduced; and a binding layer interposed between the porous matrix layer and the hemostatic layer to prevent the porous matrix layer from being separated from the hemostatic layer.

A knit hemostatic bandage provided herein can include a continuous rayon fiber and a continuous glass fiber. The knit hemostatic bandage can have a gauge of between 10 and 30 stitches per inch. The knit hemostatic bandage can have a Young's modulus of elasticity of less than 50 MPa.

A wound dressing for wireless communication with a transceiver includes a radio-frequency antenna circuit disposed on a flexible substrate, and an electrochemical moisture sensor circuit disposed on a surface of the flexible substrate. An adhesive is provided to attach the wound dressing skin of a user. The electrochemical moisture sensor is arranged between the adhesive and the flexible substrate.

A topical cushion configured to be worn in proximity to a surgical site of a patient. Such a topical cushion may be further configured to allow free movement at or near the surgical site, while preventing painful or otherwise unwanted contact.

Wound dressing compositions comprising of a bioresorbable sponge encapsulated within a polysaccharide envelope. The bioresorbable sponge is preferably comprised of collagen and oxidised regenerated cellulose. The outer polysaccharide envelope is preferably comprised of chitosan. The outer polysaccharide envelope functions to modulate the rate at which the bioresorbable sponge breaks down within a wound.

Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a spacer layer with an upper portion and a lower portion. The spacer layer can be configured to be wrapped around at least one edge of the absorbent layer with the upper portion of the spacer layer being above the absorbent layer and the lower portion of the spacer layer being below the absorbent layer. In some embodiments, a negative pressure wound therapy apparatus can include a first and second spacer layer and an absorbent layer. The first spacer layer can be positioned below the absorbent layer and the first spacer layer can have a perimeter larger than a perimeter of the absorbent layer. The second spacer layer can be positioned above the absorbent layer. The second spacer layer can have a perimeter larger than the perimeter of the absorbent layer.

A super-absorbent dressing assembly for use with a reduced-pressure wound treatment system includes a breathable, fluid restricted dry layer for placement against a wound, a super-absorbent layer, and a non-breathable layer, and a drape extending over the non-breathable layer. A reduced-pressure interface is available to fluidly couple the super-absorbent layer to a reduced-pressure subsystem. The super-absorbent dressing assembly preferably supplies a compressive force when placed under reduced pressure. A reduced-pressure treatment system uses a super-absorbent bolster to treat wounds, e.g., linear wounds.

The disclosed technology relates to a wound dressing comprising a vertically lapped material. The disclosed technology further relates to methods and uses of the wound dressing.

A wound cover device can include a backing, a micro-structure device, and one or more of a wound dressing and a skin replacement layer. The backing can be stretchable. The micro-structure device can include a plurality of fasteners, such as micro-staples, micro-pins, micro-barbs and the like, that can be used to attach the wound cover device to tissue such as skin. The micro-structure device can be stretchable to stretch with the backing. The micro-structure device can be configured such that the fasteners are positioned in a two-dimensional pattern or fill-in an interior portion of the wound dressing or skin replacement layer. The fasteners of the micro-structure device can extend through the wound dressing or skin replacement layer. The micro-structure device can additionally be placed around a perimeter or edge region of the backing.
