Systems, methods, and apparatuses for increasing liquid absorption are described. Some embodiments may include a dressing having an absorbent layer containing super-absorbent material as well as ionic-exchange media (IEM). In some embodiments, the absorbent layer may include absorbent fibers. The absorbent fibers may each include a super-absorbent core surrounded by a water-permeable layer onto which ionic-exchange media (IEM) may be grafted. As liquid comes into contact with the IEM, its ionic nature may be reduced, therefore protecting the absorbent qualities of the super-absorbent material.

The present disclosure relates to a dermal drug delivery platform comprising: a primary wound dressing comprising three-dimensional polymer protuberances that extend upward from the dressing surface to engage the wound. The protuberances comprise at least one biocompatible and/or biodegradable polymer and medicinal nanoparticles. In one embodiment, the medicinal nanoparticles may be metallic and provide surface-area-enhanced galvanic action to drive medicinal ions into the wound bed. Various methods of making the disclosed dermal drug delivery platform, as well as three-dimensional methods of treating a wound using the platform are also disclosed.

Disclosed is a wound dressing material comprising a substrate, about 2.5% to about 8% by weight of a bicarbonate, and a film-forming agent, the film-forming agent serving as a binder for said bicarbonate to said substrate, the film-forming agent and the bicarbonate being present in a ratio of between 1:2 and 2:1 with respect to one another. Also disclosed are a method for preparing a wound dressing material and a method for treating a wound.

A wound dressing is provided in some embodiments of the present disclosure. The wound dressing includes a porous substrate and a functional layer disposed on the porous substrate. The functional layer is charged or has conductivity. A method of manufacturing a wound dressing is further provided in some embodiments of the present disclosure.

A wound dressing includes a hydrophilic foam layer, a drape layer, superabsorbent projections, and printed indicators. The hydrophilic foam layer is configured to engage a wound bed and has a first side and a second side, the second side configured to face the wound bed. The drape layer has a first side and a second side, the second side configured to face the first side of the hydrophilic foam layer. The plurality of non-contiguous superabsorbent projections are fixed to and extend from the first side of the hydrophilic foam layer towards the second side of the drape layer. The one or more non-contiguous printed indicators surround one or more of the plurality of superabsorbent projections.

A method for impregnating a film, including the following steps feeding the film to be impregnated, immersing the film into an impregnating agent, and partially separating the impregnating agent from the film in order to achieve a predefined loading of the film with impregnating agent. Furthermore, a device for impregnating a film by means of an immersion basin filled with impregnating agent, a film guiding, and a separating device for separating the impregnating agent from the film in order to achieve a predefined loading of the film with impregnating agent. Furthermore, a method for manufacturing a transdermal therapeutic system.

A method of preparing an occlusive wound dressing involves preparing a slurry of an occlusive composition with a hydrophobic compound and a bacteriostatic agent, applying the occlusive composition on a fabric to produce a coated fabric, disposing the coated fabric in packaging, adding water onto at least one of the coated fabric and the packaging, sealing the packaging containing the coated fabric, and irradiating the sealed package to sterilize and produce the occlusive wound dressing. The occlusive wound dressing has from about 60 wt % to about 75 wt % hydrophobic compound, from about 2 wt % to about 5 wt % bacteriostatic agent, from about 2 wt % to about 5 wt % water, and from about 5 wt % to about 36 wt % fabric.

The invention relates to a wound dressing for absorbing exudate from a wound on which the wound dressing is placed. The wound dressing includes a porous, highly absorptive fiber dressing and a negative surface charge on a surface of the dressing.

A method (400) of manufacturing a wound dressing includes obtaining alginate fibers (108) and the step (404) of spraying either the alginate fibers (108) or a dressing or dressing layer (610) of the alginate fibers with an aqueous solution (801) comprising a polysaccharide, which can be carboxymethylcellulose. The step of spraying can occur while the alginate fibers, dressing, or dressing layer are wet. A step (405) of flash drying can follow to remove the solute of the aqueous solution to leave the polysaccharide along the alginate. The step of spraying can be selective, such that only portions of the dressing layer include the polysaccharide.

A method of preparing an occlusive wound dressing involves preparing a slurry of an occlusive composition with a hydrophobic compound and a bacteriostatic agent, applying the occlusive composition on a fabric to produce a coated fabric, disposing the coated fabric in packaging, adding water onto at least one of the coated fabric and the packaging, sealing the packaging containing the coated fabric, and irradiating the sealed package to sterilize and produce the occlusive wound dressing. The occlusive wound dressing has from about 60 wt % to about 75 wt % hydrophobic compound, from about 2 wt % to about 5 wt % bacteriostatic agent, from about 2 wt % to about 5 wt % water, and from about 5 wt % to about 36 wt % fabric.
