Abstract
A method and system for sterilizing an iodine antiseptic solution is disclosed. The iodine antiseptic solution can comprise iodine crystals and/or povidone-iodine (PVP-I). The method includes providing the iodine antiseptic solution to a closed container. And during a sterilization cycle, the method further includes heating the iodine antiseptic solution in the closed container to a sterilization temperature sufficient to generate free elemental iodine in the closed container. The method further includes applying a positive pressure in the closed container to pressurize the free elemental iodine to produce sterilized iodine within the closed container.
Claims21
A method for sterilizing an iodine antiseptic solution, the iodine antiseptic solution comprising iodine crystals and/or povidone-iodine (PVP-I), the method comprising:
- providing the iodine antiseptic solution to a closed container;
- and
- during a sterilization cycle:
- heating the iodine antiseptic solution in the closed container to a sterilization temperature sufficient to generate free elemental iodine in the closed container;
- and
- applying a positive pressure in the closed container to pressurize the free elemental iodine to produce sterilized iodine within the closed container.
A system for disinfecting epithelium of a living organism, the system comprising:
- a device having a surface configured for being placed in proximity to the epithelium of the living organism;
- and
- a container in contact with the device, the container containing sterilized iodine and being pressurized to a positive pressure, the container being configured to release the sterilized iodine under the positive pressure to disinfect the surface of the device prior to or while the surface is placed in proximity to the epithelium of the living organism to disinfect the epithelium in proximity thereof.
A sterilization system for sterilizing an iodine antiseptic solution, the iodine antiseptic solution comprising iodine crystals and/or povidone-iodine (PVP-I), the system comprising:
- a plurality of containers, each of the plurality of closed containers containing a portion of the iodine antiseptic solution;
- and
- a chamber configured to host the plurality of containers, the chamber further configured to execute a sterilization cycle to sterilize the portion of the iodine antiseptic solution in each of the plurality of closed containers, the sterilization cycle comprising:
- heating the iodine antiseptic solution in each of the plurality of containers to a sterilization temperature sufficient to generate free elemental iodine in each container;
- and
- applying a positive pressure in each of the plurality of containers to pressurize the free elemental iodine to produce sterilized iodine within each container.
