Advanced fabric technology and filters
A filter material for entrapping particles and actively affecting the trapped particles within the filter. The fabric has a blend of hydrophilic superabsorbent fibers and non-superabsorbent hydrophilic fibers that is sufficiently porous as to allow gaseous flow through the fabric. The fabric having a thickness and the fabric has as a coating of a mixture of a chemically or physically active compound and a liquid carrier forming an active composition on both the outer surface of the hydrophilic superabsorbent fibers, and the hydrophilic superabsorbent fibers have a central volume also retaining the active composition. The central volume of the hydrophilic superabsorbent fibers acting as a reservoir for replacement of the active compound into the coating when concentration of active compounds in the coating are reduced to a concentration less than concentrations of the active compound within the central volume; and the liquid carrier is an aqueous liquid.
Chitosan foam medical devices and methods
The invention provides a solid foam wound dressing useful for hemorrhage control and wound repair, as well as methods for making such a wound dressing.
Smart Bandage
A sensing chip attached to a bandage monitors the healing process of a wound by detecting growth factors, thrombin and fibrinogen. The complementary metal-oxide semiconductor includes a functionalized working electrode, functionalized counter electrode and functionalized reference electrode. The healing progress is stimulated by generating oxygen in the wound.
WOUND DRESSING
The present invention relates to a wound dressing composition for use as or in a wound dressing and to methods of making the wound dressing composition. The wound dressing composition comprises wicking material, and superabsorbent material that is punched into the wicking material. The action of punching the superabsorbent material into the wicking material acts to significantly increase the rate of absorption of the combination materials.
Honey impregnated composition dressing having super absorbency and intelligent management of wound exudate and method of making same
A super absorbent, honey-dosed foam/fiber composite, gap patterned wound dressing, comprising: a patterned foam/fiber composite structure having a gap patterned side and a non-gap patterned side, wherein the patterned side includes a pattern of foam/fiber gaps disposed between foam/fiber areas dosed with honey, where the pattern of foam/fiber gaps is formed by the honey-dosed areas, such that the patterned foam/fiber composite structure includes a layer of super absorbent material located substantially adjacent to the honey-dosed areas; and wherein a wound in contact with the gap patterned side discharges an exudate which substantially collects in the individual ones of the foam/fiber gaps causing honey in the individual ones of the honey-dosed areas to be substantially dispersed throughout a wound treatment zone and a portion of the exudate that is collected in the individual ones of the foam/fiber gaps is transferred to and collected in the super absorbent material.
Reduced-Pressure, Composite Manifolds
A reduced-pressure treatment system for treating a wound on a patient includes a composite manifold that may help prevent or minimize injury to a wound edge of the wound being treated with reduced pressure. The composite manifold includes a perimeter manifold member and an inboard manifold member. The perimeter manifold member is designed to not collapse substantially under reduced pressure in a therapy range. The perimeter manifold member may be more rigid with respect to compressibility than the inboard manifold member. A sealing member is used to form a fluid seal over the wound, and a reduced-pressure subsystem provides reduced pressure to the composite manifold. Other systems, methods, and dressings are presented.
Tissue Treatment Systems And Methods Having A Porous Substrate With A Compressed Region And An Expanded Region
A system for treating a tissue site of a patient includes a dressing filler adapted to be positioned at the tissue site. The dressing filler is comprised of a porous substrate having at least one compressed region and at least one expanded region. The compressed region of the porous substrate is held in a compressed state by a first coating capable of dissolving in the presence of a fluid, and the expanded region of the porous substrate is held in an expanded state by a second coating.

Lip and/or Nose Bandage
The invention is directed to a bandage, particularly a lip and/or nose bandage for use on wounds (surgical or traumatic), scratches, sores, cold sores, blisters, fever blisters, ulcers, pimples, lesions, and burns. The lip and/or nose bandage comprises a base sheet layer (on one end associated with at least one skin adhesive); a dressing layer; and either or both of: (the same base sheet layer) on the other end associated with at least one mucosal adhesive; and/or a malleable layer positioned between the base sheet and dressing layers.
