  • COPPER BACTERICIDE / VIRUCIDE ASSEMBLY
    Publication number: 20200147275
    Abstract: A copper bactericide/virucide assembly for killing invasive bacteria and viruses in a nostril includes a wire that is comprised of copper. In this way the wire can kill bacteria and viruses on contact. The wire is insertable into a nostril thereby facilitating the wire to contact mucous membranes within the nostril. Thus, the wire can kill invasive microbes, bacteria and viruses on the mucous membranes thereby reducing the likelihood of developing an upper respiratory infection.
