However, the use of fully hydrated, unactivated zeolites has been ignored up to this point based upon a belief that it was necessary for such zeolites to concentrate certain components in the blood by removal of water. It has now been found that fully hydrated zeolites clot blood almost as quickly as fully activated zeolites that have been dehydrated without the potentially injurious exothermic response which may cause burns in tha case of fully activated zeolites.

  • Patent number: 7332321
    Abstract: Long rod shaped M13 viruses were used to fabricate one dimensional (1D) micro- and nanosized diameter fibers by mimic the spinning process of the silk spider. Liquid crystalline virus suspensions were extruded through the micrometer diameter capillary tubes in cross-linking solution (glutaraldehyde). Resulting fibers were tens of micrometers in diameter depending on the inner diameter of the capillary tip. AFM image verified that molecular long axis of the virus fibers were parallel to the fiber long axis. Although aqueous M13 virus suspension could not be spun by electrospinning, M13 viruses suspended in 1,1,1,3,3,3-hexafluoro-2-propanol were spun into fibers. After blending with highly water soluble polymer, polyvinyl 2-pyrolidone (PVP), M13 viruses was spun into continuous uniform virus blended PVP (virus-PVP) fibers. Resulting virus-PVP electrospun fibers showed intact infecting ability to bacterial hosts after suspending in the buffer solution.

    Abstract: The invention relates to a sponge cloth based on cellulose and having an internal reinforcement, obtainable by the amine oxide process. In the process, a solution of cellulose in an aqueous amine oxide is first produced, which is then mixed with at least one pore former and fibers. The mixture is spread on a conveyor belt which is then guided through a coagulating bath comprised of a diluted aqueous amine oxide solution whose temperature is high enough such that the pore former melts and is dissolved out. Remaining amine oxide is washed out. After subsequent drying the sponge cloth layer is end-itemed. Contrary to the viscose process polymer degradation does not occur in the inventive process which results in a sponge cloth having an improved mechanical stability. A plastic net can replace the fiber reinforcement. The process is especially ecological and economical.

  • Patent number: 6979491
    Abstract: The present invention provides a yarn with antimicrobial effects. The antimicrobial antifungal effect of the yarn is derived from nanosilver particles (diameter between 1 and 100 nm) which are adhered to the yarn. The yarn contains fibers which are made of cotton, linen, silk, wool, leather, blending fabric, synthetic fiber, or any combination thereof. The yarn can be used to make cloth to be used particularly for treating patients with burns or wound. The cloth made from the antimicrobial yarn can be further used to make clothes such as underwears, socks, shoe cushions, shoe linings, bed sheets, pillow cases, towels, women hygiene products, laboratory coats, and medical robes. The present invention also provides a method for making the antimicrobial yarn.

  • Patent number: 6977231
    Abstract: A suturable adhesion-preventing membrane has high suture strength, good biocompatibility, decomposition and absorption in a living body, sufficient adhesion-preventing effect, and desirable guided tissue regeneration. The membrane is composed of at least one non-woven fabric layer made of collagen fibers, or a laminated membranous substance consisting of at least one non-woven fabric layer made of collagen fibers and at least one sponge layer made of collagen, and a coating layer of gelatin or hyaluronic acid on the surface or surfaces of the above membrane. Preferably, the membrane comprises one to six compressed cross-linked collagen non-woven fabric layers wherein a layer has a fibers having a fiber diameter of 0.05 mm to 1.0 mm, a bulk density of 5.0×10?4 to 5 g/cm3 and a thickness of 0.1 mm to 50 mm, and a coating layer containing gelatin or hyaluronic acid and having a thickness of 0.05 mm to 20 mm, wherein the coating layer covers one or both sides or a part or whole of the surface of the membrane.

  • Patent number: 6946433
    Abstract: Durable antimicrobial treatments for textile fabrics are provided. Such treatments preferably comprise silver ions, particularly as constituents of inorganic metal salts or zeolites. This particular treatment requires the presence of a resin binder, either as a silver-ion overcoat or as a component of a dye bath mixture admixed with the silver-ion antimicrobial compound. Such a treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity. The particular treatment method, as well as the treated textile fabrics are also encompassed within this invention.

  • Patent number: 6872241
    Abstract: The present invention provides an anti-pathogenic air filtration medium comprising a fibrous substrate whose fibers are coated with coating comprising a polymer. The coating provides an environment that is destructive to airborne pathogens. In particular, the filter medium can be used in a building air handling system that both filters the air and eliminates pathogens. The filter medium also can be used to create a new bio-protective gas mask that not only offers protection against chemical warfare agents, but also provides protection against biological pathogens.

  • Patent number: 6867344
    Abstract: A personal care absorbent article, such as a sanitary pad or napkin, wound dressing, and the like having one or more layers of absorbent material treated with a red blood cell lysing agent and a gelling agent. The effect of combining a lysing agent that thins menses or other blood-containing bodily fluids with a gelling agent that thickens menses or other blood-containing bodily fluids is enhanced agglomeration and increased viscosity of the blood-containing bodily fluids that come in contact with the treated material.

  • Patent number: 6852654
    Abstract: The invention is directed to a hydroentangled nonwoven fabric, the outer surface of which exhibits highly entangled fibers whereas the inner layer exhibits lightly entangled fibers. In particular, the present invention contemplates that a fabric is formed from a fibrous batt that is subjected to fluidic energy, preferably hydraulic energy, applied to one or both faces of a fibrous batt. The hydraulic energy is moderated against the basis weight of the fibrous batt to achieve the degree of surface entanglement desired. Fabrics formed in accordance with the present invention exhibit a sufficient degree of softness and non-linting performance, while providing the necessary resistance to tearing and abrasion, to facilitate use in a wide variety of applications such as cast padding or orthopedic wraps.
