    Abstract: A method and device for reducing the damaging effects of radiant energy, blast, or concussive events includes applying pressure to at least one jugular vein to reduce the egress of blood from the cranial cavity during or before the incidence of the imparting event. Reducing blood outflow from the cranial cavity increases intracranial volume and/or pressure of the cerebrospinal fluid to reduce the risk of traumatic brain injury and injuries to the spinal column. Reducing blood outflow further increases the intracranial pressure and volume, and thereby increases the pressure and volume of the cochlear fluid, the vitreous humor and the cerebrospinal fluid to thereby reduce the risk of injury to the inner ear, internal structure of the eye and of the spinal column. In addition, increasing intracranial pressure and volume reduces the likelihood of brain injury and any associated loss of olfactory function.

  • Patent number: 8822751
    Abstract: The adhesive bandage consists of a support with one surface having pressure sensitive adhesive and a wound covering pad placed centrally on it, which are covered by two protective detachable tear away tabs. The tear away tab consists of a single layer over the adhesive surface of the support and becomes two layered over the pad region. The two layers are fused at the zone of fusion near the margin of the pad, but are otherwise free from each other. The layer close to the pad, called inner barrier layer, completely covers the pad area. The outer layer, also called grasping layer, partially covers the barrier layer and the pad, and is folded upon itself to give sufficient length. When the outer layer is grasped to pull apart the releasable tear away tabs the inner barrier layer prevents contact of the finger to the pad. As one pulls apart the tear away tabs the barrier layers unfold and prevent contact of the fingers with the wound and wound exudates, preventing cross contamination.

  • 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.
