Abstract:
A wound dressing for mass casualty burn injury events is provided that is capable of being stockpiled for long periods of time without special storage conditions, may be applied by persons with little or no training, immediately restores skin barrier function and reduces pain, manages wound exudate, accommodates edema, and is transparent. The dressing does not integrate into the wound while simultaneously providing antimicrobial activity, thereby avoiding complication of the wound condition when proper medical attention is delayed for significant - periods of time.
Abstract:
A roll (80) of carrier substrate (20) is passed through a reservoir (9) of liquid PDMS (10). Doctor blade (90) meters-off excess PDMS leaving coating (11). The ePTFE sheet (30) is applied from the ePTFE unwind (31) and idler roller (33) to coating (11) in carrier substrate (20) just prior to the textile fabric (40) being applied from the fabric unwind (41) and idler roller (43). The upper surface (35) of the textile fabric (40) contacts down-line machine parts such as rollers to avoid sticking, and is passed over the support idler (46) and serpentined and "S-wrapped" over and under the rollers (70) and passed to the oven (60).
Abstract:
This invention relates to a novel method of reducing dermal scars resulting from various types of dermal injuries. Particularly, this invention relates to wound dressings and to scar management products each of which incorporate an active pharmaceutical ingredient to reduce and/or prevent dermal scarring.
Abstract:
This invention relates to a novel wound dressing design. Particularly, this invention relates to a wound dressing which incorporates multiple distinct layers, each providing useful features and together providing a novel method of managing a variety of wound types. Moist healing, exudate management, ease of use and patient comfort are provided. In a preferred embodiment, the new dressing comprises a thin layer of gel continuously coated onto a thin film material which is laminated to an apertured mesh. Preferably, the gel coated thin film material is fenestrated or perforated. This construction improves dressing fixation, provides a semi-occlusive wound environment while simultaneously managing copious amounts of exudate.
Abstract:
A microporous membrane is described comprising at least two layers, wherein each layer is characterized by nodes interconnected by fibrils, the layers are bonded by means of plastic flow at temperatures below the melting point of either membrane material, and the pore architecture is formed in situ by an expansion process. A stratified microporous membrane is produced wherein the pore architecture of each layer may be discretely controlled. The article is useful for filtration and medical applications where a pore size gradient is required.

Abstract:
Plaster or bandage has a backing sheet provided with adhesive and the sheet being a gas permeable, water impermeable membrane, made of a semi-interpenetrating polymer network. Pref. the polymer comprises fibrillated polytetrafluoroethylene and crosslinked polyorganosiloxane. The backing sheet may be transparent or translucent and is pref. waterproof upto 200 p.s.i. The adhesive is pref. pressure sensitive. Absorbent gauze can be provided.
