    Abstract: A molded porous polyvinyl alcohol sponge includes an outer skin capable of absorbing and passing water to interior portions of the sponge, and is substantially smooth except for predetermined structural details imparted by the mold used in its making. The outer skin has smaller average pore size than does the interior portion of the product.

    Abstract: A sustained and controlled release form of iodine is achieved by a complex of polyvinyl alcohol and the iodine characterized by a low water solubility. The polyvinyl alcohol may be reacted to form hydroxylated polyvinyl acetal sponge and the sponge is topically applied as an antimicrobial agent which releases controlled amounts of iodine sufficient to kill germ cells with minimal toxicity to surrounding tissue.

    Abstract: A uniformly expandable hydrophilic sponge, adapted for medical usage, characterized by instantaneous wicking and a high liquid holding capacity comprising a reaction product of polyvinyl alcohol and formaldehyde. The wicking and liquid holding capacity is attained by controlling the time, temperature and processing conditions while forming and curing the reaction product in an aqueous medium. The sponge is rendered uniformly expandable by drying the wet sponge while maintaining the shape of the wet sponge. The sponge can be made X-ray opaque by incorporating, homogeneously, throughout an encapsulated radiopaque substance with the formaldehyde and polyvinyl alcohol. The sponge is biocompatible, non-toxic, lint free, compressible, resilient, strong, non-abrasive, free of foreign leachable materials and is of exceptionally high fluid holding capacity.

    Abstract translation: 适用于医疗用途的均匀膨胀的亲水海绵，其特征在于瞬时芯吸和高液体保持能力，其包含聚乙烯醇和甲醛的反应产物。 通过在含水介质中形成和固化反应产物的同时控制时间，温度和加工条件来实现芯吸和液体保持能力。 通过干燥湿海绵同时保持湿海绵的形状，使海绵均匀地膨胀。 海绵可以通过均匀地并入包裹的不透射线的物质与甲醛和聚乙烯醇而被制成X射线不透明的。 海绵是生物相容的，无毒的，无绒毛，可压缩，有弹性，坚固，无磨蚀，无异物浸出物质，具有极高的流体保持能力。

    Abstract: A sustained and controlled release form of iodine is achieved by a complex of polyvinyl alcohol starch and iodine, characterized by the PVA based coating being insoluble in boiling water. The polyvinyl alcohol is in the form of a coating reacted with varying types of non-mineral acid containing catalysts/curing or insolubilizing agents deposited on cellulose sponge or other substrates and subsequently complexed with iodine. These cost effective sponges or wipers are topically applied as a solid state antimicrobial device, which releases controlled amounts of iodine on contact sufficient to kill germ cells, and leaves minimal residue.
