ANTITOXIC FIBERS AND FIBROUS MEDIA AND METHODS FOR MANUFACTURING SAME
20210137105 · 2021-05-13 ·

Antitoxic fibers and fabrics contain impregnated material including an antitoxin. A method for producing antitoxic fabric and products includes impregnating a fabric formed from nonpolymeric or polymeric fibers by fully immersing the fabric in a solution of a concentrate of triiodide and an additive portion that includes an oil of ethoxylated fatty acids in sufficient proportion to stabilize the triiodide in the fabric. An antitoxic fabric includes polymeric or nonpolymeric fibers and impregnated material, which includes an antitoxin, the antitoxin being triiodide, and additional chemical components including an oil of ethoxylated fatty acids in sufficient proportion to stabilize the triiodide in the antitoxic fabric. The antitoxic fabric is efficacious on contact, and maintains efficacy with negligible toxicity in use. Products with antitoxic fabric include wound dressings, gowns, surgical drapes, protective clothing, shoe covers, gloves, hair covers, air filters, including facemasks, privacy, hygienic products, curtains, medical tape, and wipes.

HEMOSTATIC MIXTURE OF CELLULOSE-BASED SHORT AND LONG FIBERS

The invention relates to a hemostatic composition comprising a mixture of cellulose-based short and long fibers, preparation and use thereof.

Hemorrhage management system

An embodiment includes a wound dressing comprising: a shape memory polymer (SMP) foam, including open cells, having first and second states; and a hydrogel (HG) included within the cells; wherein (a) in a first position a composite, including the SMP foam and the HG, is configured to be located proximate a hemorrhagic tissue with the SMP foam in the first state; (b) in a second position the composite is configured to be expanded to the second state against the hemorrhagic tissue when the SMP foam is plasticized at 37° C. depressing a glass transition temperature (T.sub.g) of the SMP foam to below 25° C. Other embodiments are described herein.

Hemostatic composition

The present invention relates to improved hemostatic compositions comprising cellulose-based fibers supplemented with compounds, preparation and use thereof.

Hemostatic mixture of cellulose-based short and long fibers

Antitoxic fibers and fibrous media contain impregnated material including an antitoxin. A method for producing antitoxic fibers and fibrous media includes impregnating a fibrous media by dipping in a dipping solution containing a concentrate of an antitoxin to form a fiber with impregnated material including an antitoxin. The impregnated material is at least about 1.0% to about 2.5% by weight of the fibers and includes additive chemical components including at least one of an anionic, cationic or nonionic component, an oil and/or an organic solvent, and an alcohol. The additives include those found in a spin finish. The antitoxin is in an amount of at least 0.1% by weight of the fiber. The manufacturing process can be applied to any woven or nonwoven media. Products with antitoxic properties formed therefrom include wound dressings, gowns, articles of clothing, surgical drapes, protective clothing, shoe covers, gloves, hair covers, air filters, including facemasks, privacy, hygienic products, curtains, medical tape, and wipes.
