Disclosed are a chitin/graphene composite sponge and a preparation method and a use thereof. The method comprises mixing and ball-milling a certain amount of flake graphite and chitin, dissolving a mixture of the flake graphite and the chitin in a NaOH/urea solvent, performing centrifugal separation, dispersing evenly, cross-linking with an epichlorohydrin cross-linking agent, standing, dialyzing, and freeze-drying, thus obtaining the chitin/graphene composite sponge.

Material comprising a flexible porous hydrophilic polymer foam or fibre matrix comprising two matrix faces and therebetween a structural matrix framework defining a network of cells, having a cell network surface and therein a network of pores and a powder charge comprising antimicrobial additive and/or wound dressing additive, wherein said powder charge is comprised at said matrix face or faces and/or within said cell network or within said structural matrix framework and wherein said additive is micronized, wherein said micronized additive has single particle size population greater than or equal to 1 micron and/or has loss on drying (L.O.D) less than 2% and/or said powder charge additionally comprises and flowing agent and/or bulking agent wherein micronized additive is co-located with said flowing agent and/or bulking agent, method for the preparation thereof comprising micronizing said additive and dosing powder charge to said matrix or a reactive phase for the manufacture of said matrix, devices comprising said material and uses thereof.

The present invention includes the composition and manufacturing of a non-prescription consumer product to treat odor and various types of inflammations, infections, and diseases. It embodies a disposable absorbent or nonabsorbent article containing unbound/freely associating adsorbent porous carbonaceous material for the entrapment and/or treatment of odor, pathogens, and adverse biological by-products. The product form includes but is not limited to tampons, panty liners, incontinence pads, diapers, sanitary towels, swabs, balls, casts, pouches, bandages and/or plugs, which contain adsorbent porous carbonaceous material that effectively reduces or eliminates adverse situations sourcing from pathogens and harmful biological by-products, including but not limited to fungi, bacteria, viruses, and parasites. The article is used to treat malodor, yeast infections, vaginitis, sexually transmitted diseases, field bullet wound holes, tooth infections, nail-bed and cuticle infections, among others by way of internal insertion and/or complete covering the body cavity, wound, and/or affected areas, creating a clear and direct path for contact with pathogens and adverse biological by-products.

A system for managing female incontinence includes a body of biocompatible material configured to fit between the labia minora and the vestibule floor, the body having a surface configured to occlude the urethral meatus, an adhesive carried on at least a first portion of the surface and configured to provide a sealing engagement between the body and the urethral meatus, and a substance carried by at least one of the body and the adhesive and configured for controlling the odor of the general vaginal-urethral area of a female.

A composition to treat atopic dermatitis having a combination of Siberian Sea Buckthorn Berry Oil at 98.0 to 99.99 of total combination percent weight; and nano diamonds at 2.0 to 0.01 of total combination percent weight respectively. In one approach, the Siberian Sea Buckthorn Berry Oil may be 99.6 to 99.8 of total combination percent weight; and the nano diamonds may be 0.02 to 0.04 of total combination percent weight respectively. In another approach, the composition may have a range of 3-8 ml of the Siberian Sea Buckthorn Berry Oil and nano diamond combination per 59 ml of a cream having 2 percent hydrocortisone. In yet another approach the composition may have 5 ml of Siberian Sea Buckthorn Berry Oil and nano diamond combination per 59 ml of a cream having 2 percent hydrocortisone.
