摘要： The present disclosure relates to wound bandages. More specifically, the present disclosure describes a vacuum sealed bandage having a film layer that is manipulable into a wound by way of negative pressure imparted by a removable medical syringe. The vacuum sealed bandage of the present disclosure does not have a vacuum pump, does not constantly apply negative pressure to the wound through an electro-mechanical device or vacuum pump, and/or does not have chords or tubes positioned to opposite sides of the film layer or extending from one side of the film layer to another side of a film layer where the chord or tube is positioned between the film and the wound.

摘要： A self-sterilizing wound dressing is disclosed. The wound dressing comprises a substrate having a first surface facing at least a portion of a wound or a surgical site and a second surface facing opposite to the first surface. At least one surface of the substrate comprises a sulfonated polymer selected from the group of perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer is sufficiently or selectively sulfonated to contain from 10 - 100 mol % sulfonic acid or sulfonate salt functional groups based on the number of monomer units, for killing at least 90% of microbes in less than 120 minutes of coming into contact with the wound dressing.
