Abstract: Embodiments herein provide hemostatic compositions comprising a plurality of liquid-expandable articles arranged on a backing material. In general, embodiments include methods for treating hemorrhagic injuries. More specifically, there is provided a method to effect rapid hemostatic response and control hemorrhage by introducing a hemostatic composition into a bleeding wound cavity. An embodiment also provides a method of preparing or manufacturing such a hemostatic composition.

Abstract: Embodiments provide a tourniquet that may be used as a daily wear belt. A tourniquet belt may include an elongate belt having a first end and a second free end; a securing element coupled to the elongate belt at the first end of the elongate belt; and a separate tightening element coupled to the elongate belt, wherein the tightening element is selectively actuable to tighten or loosen the tourniquet belt.

Abstract: Provided herein are self-expanding wound dressings that include a first outer layer, a second outer layer, and a liquid-expandable layer disposed between the first outer layer and the second outer layer, wherein the liquid-expandable layer includes a plurality of liquid-expandable articles retained by a substrate, wherein the plurality of liquid-expandable articles expand to form expanded articles upon contact with a liquid. Also provided is a method of treating an individual having a bleeding wound, the method including applying a self-expanding wound dressing to the wound. Also provided are methods of manufacturing a wound dressing, the methods including forming an absorbent material into a plurality of liquid-expandable articles, coupling the plurality of liquid-expandable articles to a substrate to form a liquid-expandable layer, and positioning the liquid-expandable layer between a first outer layer and a second outer layer to form the wound dressing.

Abstract: Disclosed herein are compression bandages that include one or more fluid bladders (such as an air bladder) disposed in or on a bandage, such as an elastic bandage. In various embodiments, the one or more bladders may be adapted to apply focused pressure to a wound site, for example where direct pressure is required in order to stop or slow bleeding. In various embodiments, such a fluid bladder may permit sufficient pressure to be applied where needed, while also preventing the over-application of pressure to other tissues in proximity to the wound.
