    Abstract: Apparatus and associated methods for a wound valve assembly provide an annular space extending radially around a central portion of a valve, which valve acts to substantially relieve pressure build up in a thoracic cavity when applied to a thoracic wound. In an illustrative example, the valve assembly may form an annular space that extends radially in all directions around a check valve. In some examples, gasses and exudates may flow substantially radially and/or parallel to the patient's local body. Various embodiments may advantageously provide open fluid communication for the gasses and exudates escaping from the wound when the valve assembly is partially covered (e.g., body armor, clothing, blankets), or when the patient may be lying down on the side of the body with the wound, for example.

  • Patent number: 8362315
    Abstract: A wound shield to manage repetitive access stress may include a conformable substrate to circumscribe a wound. Any suitable dressing may be secured to the conformable substrate providing separation between the wound and the dressing. The wound substrate may provide a site for attachment of adhesive dressings to shield the patient's skin from the pain of repetitive access and or removal of the dressings. A conformable substrate may be composed of one or more layers of any suitable material and may include adhesive on one or more surfaces to secure the substrate to the wound site and or to secure the dressing to the conformable substrate. A wound substrate may include strong adhesive to secure the substrate to the patients skin. The conformable wound substrate will be formed of any suitable non-absorbent material to permit long term application adjacent a wound. Thus many dressings may be applied and removed from a single wound substrate shielding the patient's skin from repetitive insult.

Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. The patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices come in a variety of configurations including sheet, rolled sheet, folded sheet and polygonal solids including extruded shapes. The devices are capable of serving as carriers for thrombogenic or anti-pathogenic agents. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding, and may further comprise antimicrobial or thrombogenic regions.

  • Patent number: 8263116
    Abstract: A method for producing a silver-bonded antimicrobial moist wound dressing. A silver-containing compound is added to a 0.1-30% aqueous solution of an alkaline solvent to dissociate silver ions from the silver-containing compound, dissolving CMC in water or an organic solvent to obtain a CMC solution, the silver ion-containing solution is mixed with the CMC solution so that the hydrogen ions (H+) of the hydroxyl groups of the CMC are replaced by the silver ions to prepare a silver-CMC compound, the silver-CMC compound is dispersed and absorbed in a medium, and the medium is dried.

  • Publication number: 20120226212
    Abstract: A tissue contacting material comprising a plurality of regions comprising an outer region serving as a protective barrier, one or more inner regions, and a tissue contacting region. The plurality of regions each comprise one or more of a plurality of polymers selected from the group consisting of a first polymer comprising a crosslinked hydrophilic polymer and a second crosslinked polymeric matrix, formed of a crosslinkable polymer adapted to incorporate the first polymer without substantially reacting or crosslinking with the first polymer. The first and/or second polymers provide the respective regions with one or more properties including swellability in the presence of water, active agent content, permeability to the diffusion of active agent from or through the layer, moisture vapor permeability, and adhesion to tissue.

  • Patent number: 8257732
    Abstract: A device for promoting the clotting of blood comprises a clay material in particle form and a receptacle for containing the clay material. At least a portion of the receptacle is defined by a mesh. Another device comprises a gauze substrate and a clay material disposed on the gauze substrate. Another device is a bandage comprising a substrate, a mesh mounted on the substrate, and particles of a clay material retained in the mesh. A hemostatic sponge comprises a substrate, a hemostatic material disposed on a first surface of the substrate, and a release agent disposed on a second surface of the substrate. The release agent is disposed on the wound-contacting surface of the substrate. When treating a bleeding wound, application of the hemostatic sponge causes at least a portion of the hemostatic material to come into contact with blood through the release agent and through the substrate.

  • Patent number: 8252344
    Abstract: A composition for promoting the formation of clots in blood comprises a zeolite and a binder. The zeolite is adjusted to have a specific moisture content. Processes by which the moisture content is adjusted include drying, re-hydrating, and combinations of drying and re-hydrating. A method of forming the composition comprises the steps of providing a zeolite and adjusting the moisture content such that upon application of the composition to a wound, a heat of hydration is reduced and heat transferred to the wound is reduced. A method of clotting blood flowing from a wound comprises the steps of applying the zeolite to the wound and maintaining the zeolite in contact with the wound for a predetermined amount of time, the zeolite having an adjusted moisture content and being capable of producing a controllable exothermic effect on the wound.

  • Patent number: 8252970
    Abstract: Devices and methods are disclosed for achieving hemostasis in traumatized patients. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery or military setting. In such cases, the patient may have received trauma to abdominal viscera, the thoracic cavity or the periphery. The devices utilize fluid impermeable outer surfaces and distributed pressure to achieve tamponade and hemostasis, primarily by exertion of pressure. The devices are flexible, bendable, and conformable in their wet or dry state so that they exert distributed pressure on the wound. Peripheral haemostatic packing devices include optional adhesive structures to attach one packing device to another. The hemostatic packing devices may be placed and removed by open surgery or laparoscopic access without generating excessive re-bleeding. The devices can be inserted into a wound and filled with fluid, gel, or particulates through an axially elongate tube to generate pressure to tamponade the wound.

  • Patent number: 8237007
    Abstract: Wound dressings and methods of manufacturing wound dressings are provided. The wound dressings include portions that are converted from a moisture vapor permeable material to a material having reduced moisture vapor permeability. The conversion may be accomplished in a variety of ways. In some embodiments, a solvent is used to dissolve a porous material to thereby form a non-porous film. In other embodiments, heat is applied to melt a porous material to thereby form a non-porous film. The heat may be applied using a heated gas or a heating element to directly or indirectly heat the material.
