摘要:
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.

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.

The disclosure relates to polymer films containing iodinated resin, where such films have advantageous antibacterial and/or antitoxic properties. The films may be used, for example, in medical tape, wound dressings and bandages. In certain embodiments, the invention is also directed to methods of manufacturing such polymer films, where various manufacturing difficulties have been addressed and overcome.

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.
摘要:
A substance capable of devitalizing hazardous biological agents and deactivating hazardous chemical agents comprising an activated anion exchange resin having a particle size substantially in the range of about 0.1-300 microns, which resin particles have been iodinated by exposure to a sufficient amount of an iodine-substance absorbable by the anion exchange resin such that the resin particles absorb the iodine-substance so as to convert the resin particles into activated resin particles. The iodine-substance may be selected from the group consisting of I2 (i.e., diatomic iodine), and polyiodide ions having a valence of −1. The activated resin particles may be placed into contact with the biological or chemical agent as a dry aerosol, by dust coating, or by admixing the particles with a carrier to form a coating.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
A medical glove and other elastomeric healthcare products are provided. The glove includes a base comprised of an elastomeric polymer; a barrier coating over the base; a secondary coating over the barrier coating; and a plurality of iodinated resin particulates anchored to the secondary coating. A method of coating an elastomeric material is also provided, which includes: (a) providing a base elastomer comprised of an elastomeric polymer; (b) dipping the elastomer in a first organic solution containing a polymer to form a barrier coating; (c) dipping the elastomer in a second organic solution containing a polymer to form a secondary coating over the barrier coating; (d) dipping the elastomer in an a suspension containing iodinated resin particulates in an organic solvent to anchor the particulates to the secondary coating; and (e) drying the elastomer.
