摘要： A polyvinylpyrrolidone(PVP)/Silver Sulfadiazine (SSD) hydrogel dressing in which the gel is formed by the use of electron beam (E-Beam) radiation to cross-link the polyvinylpyrrolidone (PVP); in which the color of the hydrogel dressing has been stabilized by the addition thereto of magnesium trisilicate and, optionally but preferably, also hydrogen peroxide and/or polyacrylic acid is disclosed; and also the process of stabilizing the color by adding magnesium trisilicate, to a water dispersion of PVP and SSD before it is exposed to E-Beam radiation is disclosed.

摘要： A wound dressing composition comprising a partially cured polyurethane fluid. The composition can be injected directly into a wound, where it cures to form a wound filling dressing. Also provided is a wound dressing comprising such a composition. Also provided is a kit for the preparation of such wound dressings, the kit comprising (a) a polyurethane prepolymer; and (b) a curing agent for the polyurethane prepolymer. Preferably, the polyurethane components comprise reaction products of a diisocyanate with castor oil or a related ester of ricinoleic acid or its derivatives.

摘要： Skin damage, i.e., the stripping of tissue cells from the stratum corneum, caused by removal of a backing material which has been held in adherent contact with a skin surface by means of a pressure sensitive adhesive composition coated on the backing material, is markedly reduced by incorporation of about 4 to 20% by weight of an unreacted polyol uniformly dispersed in the water-insoluble pressure sensitive adhesive mass. Suitable polyols include polyethylene glycol and polypropylene sorbitol monolaurate. This improved mass finds special application for use in conjunction with adhesive bandages or rolled tapes composed of a backing material of a plasticized film of polyvinyl chloride. Remarkably, the reduction in skin damage is accomplished without sacrificing low mass transfer to skin upon removal of the backing material, cohesive strength, adhesion, or wearability, all of which are highly desirable properties of pressure sensitive adhesive tapes and bandages.
摘要翻译： 通过去除已经通过涂覆在背衬材料上的压敏粘合剂组合物与皮肤表面保持接触的背衬材料引起的皮肤损伤，即从角质层剥离组织细胞，显着降低 通过加入约4至20重量％的均匀分散在水不溶性压敏粘合剂中的未反应的多元醇。 合适的多元醇包括聚乙二醇和聚山梨醇单月桂酸酯。 这种改进的质量发现与粘合绷带或由聚氯乙烯增塑膜的背衬材料组成的卷带一起使用的特殊应用。 值得注意的是，在去除背衬材料，内聚强度，粘合力或耐磨性的同时，不会牺牲皮肤的低质量转移，所有这些都是压敏粘合带和绷带的高度期望的性能，可以实现皮肤损伤的减少。
