    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: 8864748
    Abstract: A reduced pressure treatment apparatus includes a charging chamber storing a first pressure less than an ambient pressure and a regulated chamber storing a second pressure less than the ambient pressure. The first pressure is less than the second pressure. A conduit provides fluid communication between the regulated chamber and the charging chamber. A regulator member is operably associated with the conduit to prevent fluid communication through the conduit when the second pressure is less than or equal to a desired therapy pressure and to allow fluid communication through the conduit when the second pressure exceeds the desired therapy pressure.

  • Patent number: 8853486
    Abstract: Embodiments of the invention relate to a wound covering having a first strip-like element forming a first periphery and a second strip-like element that faces away from the first periphery, runs approximately parallel thereto, forming a second periphery, and is joined to the first strip-like element, there being formed between the first inner periphery of the strip-like element, facing away from the first periphery, and a second inner periphery of the second strip-like element, facing away from the second periphery, a drainage chamber, the depth of which in a depth direction extending at right angles to the periphery ensures a capillary action on bodily fluids received in the drainage chamber, in particular exudates.

  • 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.

  • Patent number: 8802916
    Abstract: A reduced-pressure treatment system for treating a wound on a patient includes a composite manifold that may help prevent or minimize injury to a wound edge of the wound being treated with reduced pressure. The composite manifold includes a perimeter manifold member and an inboard manifold member. The perimeter manifold member is designed to not collapse substantially under reduced pressure in a therapy range. The perimeter manifold member may be more rigid with respect to compressibility than the inboard manifold member. A sealing member is used to form a fluid seal over the wound, and a reduced-pressure subsystem provides reduced pressure to the composite manifold. Other systems, methods, and dressings are presented.

  • Patent number: 8784876
    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.
