    Abstract: A plasma sterilization apparatus to prevent color change or hardening of materials, e.g., polymers, by generating plasma in a separate plasma generation chamber and supplying it into a sterilization chamber containing an article to be sterilized. A plasma generation chamber includes electrodes installed in close proximity to each other, preferably separated by 0.5-40 cm, to generate plasma with high density even with a small capacity high frequency power source. The electrodes are connected to a high frequency power source to generate the plasma. An injection heater evaporates an aqueous hydrogen peroxide solution used as a microcidal agent, and injects the resulting vapor along with air into the plasma generation chamber. A sterilization chamber communicates with the plasma generation chamber at a remote position through a control valve. A vacuum pump is connected to the sterilization chamber, to form a vacuum state in the sterilization chamber.

The method comprises the steps of: providing an internal electromagnetic radiation source to sterilize mail deposited in the mail box; providing an electric door switch serially connected to the electromagnetic radiation source adapted to close only when the mail box door is closed so that the electromagnetic radiation radiates from the source only when the front door is closed; and, providing a sterilization timer activated when the mail box door is closed, said timer configured to maintain the electromagnetic source on for a sufficient period after the mail box door is closed to radiate and thereby sterilize any mail deposited therein. One aspect of the invention comprises a method of retrofitting a mail box with an assembly containing all of the components listed above.

  • Publication number: 20030156972
    Abstract: Ispaghula (material from the plant Plantago ovata, useful as an agent in relieving constipation, is subjected to treatment with -radiation at a dose of up to 13 kGy, and preferably in the range 5-10 kGy. As well as effecting sterilisation of the ispaghula, this dose of irradiation has been shown to offer surprising rheological advantages.

  • Publication number: 20030156973
    Abstract: The connection, assembly, or fill of two or more pre-sterilized components 10,12 having at least one terminal end 14 each for attachment to another component, and an apparatus for performing such a connection, while maintaining the sterility of the components is disclosed. The resulting connection is made permanent by bonding the contacting components 10,12 together using either a solvent bonding technique, a radio frequency sealer, a heat sealer, or any other suitable process. The connection is preferably made within an active sterile field 60. Using a low-voltage electron beam instrument 54, such as the MIN-EB™, a suitable sterile field sphere can be created. The terminal ends 14 of the multiple components 10,12 remain within the sterile field sphere 60 until the possibility of contamination within the sealed components is significantly reduced to industry acceptable standards.

  • Patent number: 6607695
    Abstract: A sterilized chemical composition is stored in a sterile environment for a prolonged period of time, hermetically sealed in successive enclosures and a shipping enclosure. The third sealing layer is removed prior to entering a storage area. The second layer is removed prior to taking the container to the sterile environment. The storage area may also be sterile. The innermost container may be an aerosol container and the composition a disinfectant liquid such as alcohol. The entire shipping enclosure and contects is preferably sterilized with gamma radiation.

  • Patent number: 6605454
    Abstract: A microwave device has a monolithic microwave integrated circuit (MMIC) disposed therein for applying microwave radiation to a microfluidic structure, such as a chamber, defined in the device. The microwave radiation from the MMIC is useful for heating samples introduced into the microfluidic structure and for effecting lysis of cells in the samples. Microfabrication techniques allow the fabrication of MMICs that perform heating and cell lysing of samples having volumes in the microliter to picoliter range.

  • Publication number: 20030149128
    Abstract: A method of sterilizing a polymerizable monomeric adhesive composition includes: providing a polymerizable monomeric adhesive composition in a container, the polymerizable monomeric adhesive composition including a polymerizable 1,1-disubstituted ethylene monomer and at least one stabilizer; holding the composition in the container for a pre-determined amount of time, which is sufficient to inhibit or eliminate polymerization of the monomer during or immediately after sterilization, before sterilizing the composition; and sterilizing the polymerizable monomeric adhesive composition inside the container.

  • Publication number: 20030143107
    Abstract: A method for sterilizing products to inactivate biological contaminants such as viruses, bacteria, yeasts, molds, mycoplasmas and parasites is disclosed. The method involves irradiating the product at a low dose rate from about 0.1 kGy/hr. to about 3.0 kGy/hr. for a period of time sufficient to sterilize the product. The method does not destroy sensitive materials such as blood and blood components. Further, the method does not require pre-treatment of the product such as freezing, filtration or the addition of chemical sensitizers.

  • Publication number: 20030141260
    Abstract: Methods for decontaminating fluids such as blood products, particularly platelets or red blood cells, are provided. The methods include mixing substantially non-toxic amounts of an endogenous photosensitizer such as riboflavin, or an endogenously-based derivative photosensitizer, with the fluid, increasing the dissolved oxygen content of the fluid to an amount sufficient to enhance a reaction of the photosensitizer in which singlet oxygen is formed and reduce competing reactions; and exposing the fluid to visible light photoradiation to activate the photosensitizer and substantially inactivate the pathogens. Blood products produced by the method, and systems for carrying out the method are also provided.

  • Patent number: 6596230
    Abstract: A device and method for inactivating pathogens in therapeutic fluids with sterilizing radiation in a continuous thin fluid flow arrangement that exhibits radiation dose uniformity for fluids having high optical densities. Radiation dose uniformity is achieved in part through a “carrying” mechanism that moves or carries the fluid, thereby eliminating a channel flow velocity profile where flow volumes near the channel walls run the risk of overexposure to the radiation due to very large residence times within the channel. The device comprises a relatively flat belt chamber (22) connected to a fluid flow through an inlet (24) and an outlet (26) on the belt chamber (22). The belt chamber (22) has a top surface (28) and a bottom surface (30). A radiation permeable plate (32) is disposed adjacent the top surface (28) of the belt chamber (22) and is in contact with the belt chamber (22). A radiation source (42) is provided adjacent to the plate (32) adjacent to a side opposite the belt chamber (22).
