  • Publication number: 20140309574
    Abstract: Wound dressings, methods for their production and components for use therein. A knitted structure comprising a blend of gelling fibres and non-gelling fibres wherein the yarn comprises at least 50% w/w gelling fibres, a three-dimensional textile material comprising gelling fibres, and a yarn comprising a blend of gelling and non-gelling fibres which may be used in their production, the knitted structure and three-dimensional textile material beings suitable for use as wound dressings or as components of composite wound dressings. The wound dressings may be adapted for use in negative pressure wound therapy (NPWT). It has been found that the incorporation of gel-forming fibres provides a material which has a high absorbency, enabling good transfer of exudates away from a wound, which retains structural integrity, and which is non-adherent and easily removed from the wound.

  • Publication number: 20140296763
    Abstract: A protective device configured in accordance with a particular embodiment includes a cover including a first region that extends over a vulnerable site on a patient and a second region that extends over an area on the patient peripheral to the vulnerable site. The first region of the cover is at least generally impermeable to liquid water. The device further includes an adhesive film and a liquid-absorbing element. The adhesive film is configured to form an adhesive bond between the second region of the cover and the patient. The bond has an inner edge portion positioned toward the vulnerable site and an outer edge portion positioned away from the vulnerable site. The liquid-absorbing element is configured to absorb liquid contamination at the outer edge portion of the bond and/or liquid contamination approaching the outer edge portion of the bond when the cover is operably positioned on the patient.

  • Patent number: 8846076
    Abstract: A hemostatic device for promoting the clotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.
