  • Publication number: 20140272030
    Abstract: A method and a system for producing a change in a medium. The method places in a vicinity of the medium an energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The energy modulation agent has a normal predominant emission of radiation in a first wavelength range outside of a second wavelength range (WR2) known to produce the change, but under exposure to the applied initiation energy produces the change. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.

  • Publication number: 20140263091
    Abstract: Improved fluid sanitization assemblies are provided. More particularly, the present disclosure provides improved fluid/water sanitization assemblies utilizing UV light and/or ozone. The UV light and/or ozone can be generated via light emitting diodes (“LEDs”) (e.g., via UV LEDs). In certain embodiments, by emitting light at a wavelength of about 250 nm to about 270 nm (e.g., 253.7 nm), the fluid sanitization assemblies thereby disinfect and/or sanitize fluid/water. The present disclosure provides for a fluid sanitization assembly including a pressure vessel configured and dimensioned to house fluid; a plurality of light emitting diodes (“LEDs”) mounted with respect to the pressure vessel, each LED mounted with respect to the pressure vessel via an optic member; wherein each optic member is configured and dimensioned to focus and direct UV light emitted from its associated LED to the fluid within the pressure vessel for sanitization purposes.

  • Patent number: 8747764
    Abstract: An inline intravenous (IV) fluid sterilization system can be located within directly upstream of the patient's access point, downstream of any breach points, so as to ensure fluid sterility. The chamber space between the walls is accessed by a fluid inlet port and a fluid outlet port between which the fluid flows. The inlet port is connected to a conduit/tubing from the fluid source and the outlet port is interconnected with a conduit/tubing that is free of breach points and interconnects to the patient access point. The inner wall allows for transmission of UV light into the fluid space. The walls define a space therebetween that is relatively small radially, allowing for a sufficient flow rate, but providing a large surface area and small fluid depth for exposure to the UV light. The UV light is provided by an elongated lamp within a cavity of the inner wall.
