| 20090253327 | Antimicrobial nonwoven filters composed of different diameter fibers and method of manufacturing the same - The present invention is directed to manufacturing an antimicrobial nonwoven material composed of two or more distinct fibers that are entangled to form a three-dimensional nonwoven web. The individual fiber components of the web are chosen to have properties that impart both excellent filtering capacity and antimicrobial activity to the web. At least one fiber of the composite web is selected to have excellent filtering characteristics. Moreover, at least one fiber of the composite web is selected to be able to incorporate an active agent, such as an iodinated resin, with a sufficient loading capacity and diffusivity such that the active agent can migrate to the surface of the fiber and exert its antimicrobial effect. | 10-08-2009 |
| 20090259158 | Antimicrobial fibers embedded with an iodinated resin - The present invention provides a fiber with iodinated resin particles embedded therein. The innovative fibers a show no or negligible leaching of iodine into the atmosphere and thus are not toxic. In one aspect, the antimicrobial fibers can be bonded or woven together to form a filter media. Examples of nonwoven filters are provided. Additionally, an electric charge can be applied across the nonwoven substrate to increase antimicrobial efficacy. | 10-15-2009 |
| 20090277450 | Nontoxic antimicrobial filters containing triclosan - The present invention comprises nontoxic, environmentally friendly triclosan-containing antimicrobial filters composed of two layers, a filtering layer and a backing layer used to trap any triclosan released from the filtering layer. The filter media can be used in various applications including filter closures for facemasks. | 11-12-2009 |
| 20100074858 | Novel iodinated resin manufacturing process and product - The invention provides a novel method for manufacturing iodinated resin particulates that have widespread utility as disinfectants. The invention also provides novel iodinated demand disinfectant iodinated resins that have superior properties than resins known in the art. The novel manufacturing process of the current invention is highly efficient and environmentally friendly and is conducted without the presence of water. Additionally, the manufacturing process produces iodinated resins that have better overall biological performance than resins produced by prior art methods owing to higher degrees of iodine in the manufactured resin particulates and higher degrees of uniformity of iodine content when comparing particulate to particulate. | 03-25-2010 |
| 20100313890 | PROTECTIVE MASK WITH BREATHABLE FILTERING FACE SEAL - The invention is directed to a protective mask that has high filtration efficiency, yet is easy to breathe through and is comfortable to wear. The mask includes a thin filter body layer configured to cover the mouth and nose of a user when the mask is worn and a thicker compressible gasket positioned along a periphery of the mask. The gasket comprises a high loft, porous dielectric filtering material that forms a breathable closure about the user's face without forming an airtight seal, such that the user can draw breathable air from the sides, top, and bottom of the mask. The mask preferably includes a outer scrim coated with biocidal iodinated resin to provide surface antibacterial properties. | 12-16-2010 |
| 20100316588 | METHOD FOR COATING AN ELASTOMERIC MATERIAL WITH A LAYER OF ANTITOXIC MATERIAL - The invention relates to elastomeric products that are coated with a thin layer of elastomeric polymeric coating containing an antitoxic agent, particularly a demand disinfectant iodinated resin. The antimicrobial coated catheters are prepared by adding the antitoxic agent to a solution of a liquid elastomeric polymer and then coating the surface of the elastomeric through a dipping or spraying procedure. The antimicrobial coatings can be applied to a variety of different elastomeric products including gloves and catheters and are capable of providing a high level of protection against microbes and other contaminants. | 12-16-2010 |
| 20110256527 | RAPID AND SAFE TECHNIQUE FOR PERFORMING PCR AMPLIFICATIONS - This invention relates to methods for quick and safe identification of pathogens from biological samples. Iodinated resins may be employed to destroy a pathogen while leaving the pathogen's DNA in a state that can be analyzed. The DNA can then serve as a substrate for PCR analysis. The use of these iodinated resins work in a significantly quicker manner than prior art methods and allows scientists to spend a minimal time under Biosafety Level Three (BSL-3) conditions. | 10-20-2011 |
