20100260824 | Antimicrobial Foam Compositions, Articles and Methods - Articles may be formed including: at least one layer of foam, the foam layer and at least one antimicrobial agent associated with foam layer, the antimicrobial agent including PHMB, PEHMB, or derivatives thereof; at least one non-adherent layer disposed on at least a portion of the foam layer, the non-adherent layer being permeable to moisture; and a film disposed on at least another portion of the foam layer, the film being breathable to allow escape of moisture, but substantially impermeable to bacteria. Another article may include at least one layer of foam, the foam having pores of different sizes, at least some of the pores at least partially filled with at least one elutable antimicrobial agent, the pores of different sizes forming a gradient with the foam layer. Yet another article may include a foam matrix and a plurality of dissolvable members disposed with the foam matrix, at least one antimicrobial agents associated with the dissolvable members such that upon dissolution thereof the antimicrobial agent is eluted and pores or voids are created in the foam matrix. Wound dressings formed from the above articles are also described. | 10-14-2010 |
20100331797 | SELF CONTAINED WOUND DRESSING APPARATUS - The composite wound dressing apparatus promotes healing of a wound via the use of a vacuum pump. The vacuum pump applies a vacuum pressure to the wound to effectively draw wound fluid or exudate away from the wound bed. The vacuum pump is tethered to the wound dressing and is portable, preferably, carried by the patient in a support bag, which permits patient mobility. Moreover, the patient does not need to be constrained for any period of time while exudate is being removed from the wound. | 12-30-2010 |
20120089069 | Medical Dressing Containing Antimicrobial Agent And Related Methods Therefor - A medical dressing containing an antimicrobial agent is disclosed. The medical dressing comprises a layered fabric comprising an inner layer of substantially hydrophilic material, an outer layer of substantially hydrophobic material on both sides of the inner layer; and an antimicrobial agent. The antimicrobial agent may be releasably impregnated into the fabric, coated on said fabric or a combination thereof. The antimicrobial agent may be a biguanide, such as polyhexamethylene biguanide (PHMB). The fabric inner layer material may be substantially a cellulose fiber, preferably substantially rayon, and the fabric outer layer material may be substantially polyester, e.g., a combination of textile matrix grade polyester fiber and amorphous binder grade polyester fiber. The fabric is preferably treated with an aqueous solution of surfactant and PHMB to have about 1500-3500 ppm of extractable PHMB. | 04-12-2012 |
20120177720 | MULTI-LAYER WOUND DRESSINGS - A wound dressing includes one or more layers containing a first anti-microbial agent and optionally at least one of: a chelating agent, a second anti-microbial agent, a zinc-containing agent, a cell-signaling agent, and an additional active ingredient or agent. | 07-12-2012 |
20120310186 | Dressings and Related Methods Therefor - The present disclosure relates to dressings, such as adhesive bandage, which can have an absorbent pad, and non-stick film secured thereto which has at least two different polymeric materials, a first polymeric material and a second polymeric material having a lower melting point than the first polymeric material. | 12-06-2012 |
20130085434 | Wound Dressing And Related Methods Therefor - A wound dressing includes a substrate fabricated from first and second yarns. The first yarns include at least one of a bast fiber, a cellulosic fiber, and combinations thereof and the second yarns include at least one alternative polymeric fiber. | 04-04-2013 |
20130150764 | Non-Adherent Wound Dressings and Related Methods Therefor - A wound dressing is disclosed. The wound dressing includes an oil emulsion and a substrate including a plurality of first yarns and a plurality of second yarns, wherein the plurality of first yarns includes a plurality of first fibers comprising a cellulosic material and the plurality of second yarns includes a plurality of second fibers comprising a non-adherent polymeric material. In other cases, the substrate can be a woven substrate, a nonwoven substrate, or a knitted substrate of nonadherent polymeric fibers or yarns. | 06-13-2013 |
20130331822 | SELF CONTAINED WOUND DRESSING APPARATUS - The composite wound dressing apparatus promotes healing of a wound via the use of a vacuum pump. The vacuum pump applies a vacuum pressure to the wound to effectively draw wound fluid or exudate away from the wound bed. The vacuum pump is tethered to the wound dressing and is portable, preferably, carried by the patient in a support bag, which permits patient mobility. Moreover, the patient does not need to be constrained for any period of time while exudate is being removed from the wound. | 12-12-2013 |
20140039349 | URINE COLLECTION SYSTEM, APPARATUS AND METHOD - A urine collection system includes a collection bag defining a fluid reservoir including a fluid inlet and a fluid outlet, an in-line vent positioned upstream of the collection bag and being fluidly coupled to the collection bag, the in-line vent including an outlet end, a sampling port adapter positioned upstream of the in-line vent and being adapted to be fluidly coupled to a urinary catheter; and a compressible tube defining a fluid channel fluidly connecting the sampling port adapter and the in-line vent, the compressible tube being clampable to seal the fluid channel. | 02-06-2014 |
