摘要:
A dressing composition for use as a skin dressing comprises an elastomeric-adhesive composition, and a zeolite comprising releasably adsorbed nitric oxide. The zeolite may comprise a transition metal cation such as Co, Fe, Mn, Ni, Cu, Zn, Ag or a mixture thereof as an extra-framework metal cation, preferably Zn. The elastomeric adhesive composition may be a hydrocolloid-adhesive composition comprising, hydrocolloid and elastomer. The dressing composition releases nitric oxide, which may have beneficial effects, when used on wounds or moist skin, with a substantially constant release rate over a long period of time. A dressing including a layer of the dressing composition has a backing layer and may have a release liner removably attached to the skin-contacting surface of the dressing layer.

A wound dressing comprising an open-cell foam substrate infused with an ion-containing composition in a water-dispersible carrier is provided. The composition includes citric acid or a salt thereof; salts of potassium, rubidium, and zinc ions; and a carrier comprising two or more polyol components, at least one polyol component being solid at 23 degrees C. A method of treating a wound with said wound dressing is also provided.

La présente invention a pour objet une composition polymérique destinée à améliorer la cicatrisation de la peau, notamment en activant la synthèse du collagène à la surface de la peau lésée. La composition de l'invention comprend une matrice polymérique et des charges minérales uniformément dispersées dans la matrice polymérique ayant des propriétés d'absorption et/ou d'émission dans la région d'infrarouge lointain 2-20 µm.
摘要:
A hemostatic device for promoting the clotting of blood includes a gauze substrate, a clay material disposed on the gauze substrate, and also a polyol such as glycerol or the like disposed on the gauze substrate to bind the clay material. When the device is used to treat a bleeding wound, at least a portion of the clay material comes into contact with blood emanating from the wound to cause the clotting. A bandage that can be applied to a bleeding wound to promote the clotting of blood includes a flexible substrate and a gauze substrate mounted thereon. The gauze substrate includes a clay material and a polyol. A hemostatic sponge also includes a gauze substrate and a dispersion of hemostatic material and a polyol on a first surface of the substrate.
摘要:
The present invention utilizes a combination of a porous carrier and inorganic material is selected from the group consisting of diatomaceous earth, glass powder or fibers, precipitated or fumed silica, kaolin and montmorillonite clays, and Ca exchanged permutites to make a more effective hemostatic device to treat wounds in mammalian animals. These hemostatic devices provide a lower heat rise to the skin as compared to direct application of zeolites to the skin.

The present invention relates to textiles endowed with bioactive protection against air or water borne toxic chemicals such as pesticides, nerve agents, phenols, polycyclic aromatic hydrocarbons, etc. More specifically, the object of the invention is a textile material carrying immobilized biocatalysts able to actively degrade toxic chemicals adsorbed onto it. The textile material of the invention can be used to manufacture bioactive interlining element of protective garments or it may, but not exclusively, be used was the bioactive layer of filter masks, gloves and other protective devices. In particular, the present invention relates to a bioactive textile material comprising (i) a textile support; (ii) a bioactive layer either on one or both aides of the said textile support, the bioactive layer comprising a nanostructured xerogel film which comprises an immobilized bloactive enzyme.
