  • Iodine-based microbial decontamination system
    Patent number: 5772971
    Abstract: A microbial decontamination system includes a chamber for housing items to be decontaminated as well as a source of one or more iodine-containing fluids that are conveyed to the chamber as necessary. The system also includes a detector element for monitoring the concentration of free iodine within the chamber. A signal representative of the free iodine concentration is conveyed to a controller element which communicates with receptacles for housing the iodine-containing fluids so that additional iodine-containing fluids may be added to maintain the free iodine concentration within the chamber at a desired level.

  • Iodine germicides that continuously generate free molecular iodine
    Patent number: 5962029
    Abstract: A method for forming an iodine disinfecting solution that continuously generates free molecular iodine at a controlled average rate of at least 0.2 ppm per hour over a sustained and extended time period. The method involves combining persulfate anions and iodide anions in sufficient quantity in an aqueous medium having a resulting pH of less than about 6.5 so as to create an iodine generating capacity in said aqueous medium of between 1.5 and 6.5 with a generated concentration of at least 5 ppm of free molecular iodine and maintaining this concentration over the course of the extended time period.

  • Methods and pharmaceutical compositions for oral delivery of molecular iodine
    Patent number: 5885592
    Abstract: The invention is a method of administering therapeutic iodine for treating a disorder in a mammal. The invention comprises a step of feeding said mammal an effective amount of an oxidant for an iodine species and an iodine reductant which will cause oxidation-reduction reactions upon contact with the gastric juices present in the stomach of the mammal. This is done such that molecular iodine is generated in vivo at a ratio of molecular iodine to total iodine of above at least about 0.65. The invention also discloses a non-aqueous pharmaceutically acceptable carrier with said oxidant and reductant having the ability to cause oxidation-reduction reactions upon contact with the gastric juices present in the stomach of said mammal and in an amount sufficient to generate molecular iodine, in vivo, at a ratio of molecular iodine to total iodine of above at least about 0.65.
