  • Patent number: 10058106
    Abstract: According to the present invention, a sterilant can be injected into a container without residual water on an object to be sterilized. The method includes decreasing a pressure in the container to a pressure higher than the triple point pressure at which water freezes. The method further includes comparing an actual time required for decreasing the pressure and a reference time, or comparing an actual rate of pressure increase and a reference rate to detect residual water on the object. If the residual water is detected, the pressure in the container is increased to the atmospheric pressure or the quasi-atmospheric pressure and the object is heated, and then the pressure is decreased to drain the residual water through the decompression boiling. The step of draining the residual water is repeatedly performed until no residual water is detected on the object and subsequently the sterilant is injected into the container.

  • Patent number: 8871146
    Abstract: An object of the present invention is to efficiently sterilize microorganisms present in or on a surface of a liquid. Plasma is generated in a vicinity of or in a manner to make contact with a liquid whose pH value is adjusted to become 4.8 or lower, more preferably 4.5 or lower. The plasma is generated in an atmospheric gas containing nitrogen, e.g., in the air. Superoxide anion radicals (O2?.) that are generated by the plasma react with protons (H+) in the liquid to form hydroperoxy radicals (HOO.). Further, nitrogen and oxygen included in the air are combined together by the action of plasma to form nitrogen oxide such as nitric oxide (NO.). The nitric oxide (NO.) combines with the hydroperoxy radicals (HOO.) to become peroxynitrite (ONOOH(ONOO?)) having a high microbiocidal activity.

    Abstract: An apparatus and method of producing an atmospheric non-equilibrium plasma (ANEP) in a sealed container having a selected working gas and an object to be treated is described. A variety of working gas mixtures including air, O2, N2, CO2, He and Ar, in combination with a range of ionization gradients, voltages and ANEP column lengths was investigated so as to establish effective ranges of the variables using the sterilization of a sample as a measure of effectiveness. Certain combinations of working gas, voltage gradient, voltage and ANEP column length were found to have greater effectiveness. The approach may be used for food products, medical equipment, or other objects where treatment with reactive gas atmospheres is effective.

  • Patent number: 8623274
    Abstract: A microfibrillar high molecular weight chitosan-based textile can be used as a hemostat. The chitosan has been treated in a nitrogen field by applying energy to ionize nitrogen in and around the chitosan textile. A single or multiple such treatments may be employed. For example, the chitosan textile may be irradiated under nitrogen using ?-irradiation, treated under a nitrogen plasma, or both.

  • Patent number: 8586944
    Abstract: An electron beam emitter including a vacuum chamber having a width. An electron generator can be positioned within the vacuum chamber for generating electrons. An elongate nozzle can extend from the vacuum chamber along a longitudinal axis and have an exit window at a distal end of the nozzle. The nozzle can have a width that is less than the width of the vacuum chamber. The electron generator can be shaped and dimensioned, and positioned with the vacuum chamber to form and direct a narrow electron beam that enters and travels through the nozzle, and exits out the exit window.

  • Patent number: 8574490
    Abstract: Methods and apparatus for preventing patient bloodstream infection by microorganisms during administration of various medications or fluids through IV lines. In particular, the invention reduces contamination of IV lines, connecters, stopcock valves, manifolds, ports, etc. by means of irradiation by violet and/or blue light. Each embodiment comprises a source of violet and/or blue light and an optical element optically coupled to that light source for shaping the radiation pattern of the light emitted by the light source. Preferably, a light-emitting diode or a laser diode that emits light in the desired wavelength can be used. The optical element, optically coupled to the light source, is embedded or installed in or attached to a component of an IV set, the emitted light being directed to a “point of entry” or any other stagnation point of an IV set.

  • Patent number: 8475712
    Abstract: An arrangement for the exposure of a pumpable medium to an electric field. The arrangement comprises, at least two power supplies (100) for the generation of electrical voltage, at least one non-conducting chamber (102) for pumping said pumpable medium, which said at least one chamber (102) is provided with a first (106) and a second electrode plate (108), a control means (104) for controlling said at least two power supplies (100). During control the control means (104), by synchronous control, establishes a series connection between at least two of said at least two power supplies (100), the first electrode plate (106) and the second electrode plate (108). A resulting composite voltage arises between the first (106) and the second electrode plate (108), which resulting composite voltage will result in an electric field between the first (106) and the second electrode plate (108). The pumpable medium is exposed to the electric field.

  • Patent number: 8409500
    Abstract: A bottle, a system and a method sterilize a liquid. The bottle has an interior to hold the liquid and an ultraviolet light emitting lamp that extends into the interior. A cord may be attached to the bottle so that pulling the cord may power the ultraviolet light emitting lamp and/or charge a battery used to power the ultraviolet light emitting lamp. The bottle may have a status light that indicates that the ultraviolet light emitting lamp may have an amount of power equal to or greater than a threshold value, such as, for example, an amount of power necessary for the ultraviolet light emitting lamp to operate for ninety seconds. The bottle may have a removable lid located opposite to the ultraviolet light emitting lamp.

  • Patent number: 8409499
    Abstract: A method provides for sterilizing with radiation objects which have a low bioburden and which are sensitive to radiation. A dosage of radiation sufficient to ensure sterilization without damaging the object is determined by determining the bioburden upon one or more samples of the objects, determining an estimate of the dose that results in a preselected probability (e.g., 0.1, 0.01, 0.001, 0.0003162 . . . etc. (i.e., SAL=10?1, 10?2, 10?3, 10?3.5 . . . etc.

  • Publication number: 20130064711
    Abstract: A method for manufacturing of ultrahigh molecular weight polyethylene (UHMWPE) for implants, where the implants have been machined out of UHMWPE blocks or extruded rods, has anthocyanin dispersely imbedded in the polyethylene. The implant is then exposed to ? ray or electron beam irradiation in an amount of at least 2.5 Mrad followed by a heat treatment to prevent the implant from becoming brittle in the long term as well as to improve strength and wear. The method includes mixing a powder or granulate resin of UHMWPE with an aqueous liquid that contains anthocyanin in a predetermined amount. The water is then evaporated to deposit the anthocyanin in a predetermined concentration on the polyethylene particles. The doped UHMWPE particles are compressed into blocks at temperatures in a range of approximately 135° C.-250° C. and pressures in a range of approximately 2-70 MPa. Medical implants are made from the blocks.
