    • The present invention provides new compressed absorbent aggregates suitable for use in urostomy bags and the like. According to a presently preferred embodiment of the present invention there is provided a compressed absorbent aggregate comprising: 60 to 80 % by weight superabsorbent; 20 to 40 % by weight microcrystalline cellulose; and optionally 0.1 to 10 % by weight hydrophilic lubricant. The compressed absorbent aggregates may be in the form of tablets. This facilitates insertion into an ostomy bag, for example, via an integral addition port. The tablets are fast-disintegrating in the presence of aqueous media, generally taking from 1 to 10 minutes to disintegrate completely in the presence of sufficient water. The presence of the superabsorbent polymer promotes steady progressive thickening of the liquid into a gelled but flowable consistency without forming a stiff intractable gel. The thickened contents may be expelled from the bag via an integral valve, thus allowing for re-use of the bag.
    • 本发明提供适用于造瘘袋等的新的压缩吸收性骨料。 根据本发明目前优选的实施方案,提供了一种压缩吸收性聚集体,其包含:60至80重量%的超吸收剂; 20〜40重量%的微晶纤维素; 和任选的0.1至10重量%的亲水润滑剂。 压缩的吸收性聚集体可以是片剂的形式。 这便于插入造口袋,例如通过整体加入口。 片剂在含水介质的存在下快速崩解,通常在足够的水的存在下,1至10分钟完全崩解。 超吸收性聚合物的存在促进了液体的稳定渐进增稠,使其成为凝胶状但可流动的稠度,而不形成刚性顽固的凝胶。 增稠的内容物可以通过一体的阀从袋中排出,从而允许袋的再次使用。
