    "inventor_name": "Joseph Landolina",
    "publication_year": 2014,
    "device_name": "Veti-Gel Bandage",
    "goal": "Rapidly stop traumatic internal and external bleeding (hemostasis) without applying pressure.",
    "problem_addressed": "Uncontrolled bleeding in veterinary and (later) human wounds, where current bandages are slow or require pressure.",
    "concept_summary": "A plant-derived gel composed of haemophilic polysaccharide polymers that cross-link in situ to form a mesh that adheres to blood, sealing the wound within seconds.",
    "detailed_description": "The gel contains a mixture of polyanionic polymers (e.g., alginates, hyaluronates) and polycationic polymers (e.g., chitosan, DEAE-Dextran) that, when combined with a cross-linking agent such as calcium chloride, solidify on contact with a wound. The resulting hydrogel matrix captures blood cells, accelerates clot formation, and creates a biocompatible barrier. The product is supplied in a syringe-type applicator for direct topical use. A version is being developed that can be left in the body and gradually absorbed.",

        "A graduate from Polytechnic Institute of New York University (NYU) has invented a gel that can stop bleeding and seal serious wounds in just 15 seconds.",
        "The gel is the brainchild of Joe Landolina... when you mix them together, they become a solid mass. That was the Eureka moment for me.",
        "The veterinary version of Vetigel will hopefully be available from early 2015 in the US and UK, followed by Europe, Asia, Australia and Africa.",
        "For the first FDA approval, Vetigel will need to be removed by a doctor or surgeon and the wound will need to be stitched up or treated the usual way in a hospital."
