  • Patent number: 10842502
    Abstract: A system 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.

  • Publication number: 20140371650
    Abstract: A unique multi-functional emergency bandage is introduced, wherein bleeding is stopped by: (1) optimizing mechanical properties and preventing ischemia and/or necrosis while applying enough pressure to help stop bleeding, and (2) incorporating inorganic anti-bleeding nano-structures (embedded within a gauze and/or microbial cellulose) with almost infinite life-time. Additionally, pathogen passage through the bandage is prohibited (via an intermediate filter layer). Together with the overall anti-microbial character of the bandage, the unique multi-functional bandage offers all these vital features within a single design. The unique bandage can be applied by using a single hand and bandaging direction can be changed using a unique binding apparatus.

  • Patent number: 8907153
    Abstract: The present invention is drawn to adhesive peel-forming formulations for dermal delivery of a drug. The formulation can include a drug, a solvent vehicle, and a peel-forming agent. The solvent vehicle can include a volatile solvent system having one or more volatile solvent, and a non-volatile solvent system having one or more non-volatile solvent, wherein the non-volatile solvent system has a solubility for the drug that is within a window of operable solubility for the drug such that the drug can be delivered at therapeutically effective rates over a sustained period of time. The formulation can have a viscosity suitable for application to a skin surface prior to evaporation of the volatile solvents system. When applied to the skin, the formulation can form a solidified peelable layer after at least a portion of the volatile solvent system is evaporated.

  • 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.
