摘要： Absorbent articles such as sanitary napkins, panty liners, adult incontinence devices, and the like are disclosed. The absorbent articles described herein comprise a foam absorbent structure comprising a hydrophilic, flexible, nonionic polymeric foam structure of interconnected open cells which is particularly suitable for absorbing blood and blood-based liquids. The foam structure is resiliently compressible and has resistance to compression deflection of from about 5% to about 85% when measured under a confining pressure of 0.74 psi at 31.degree. C. after 15 minutes. In preferred embodiments, the foam structure is compressible under such forces that when it is placed in the space between the wearer's labia majora, it will be compressed without deforming the wearer's labia majora, and will be molded by the wearer's labia and conform to the shape thereof. The absorbent structure may comprise an acquisition/fit portion and a storage portion wherein the acquisition/fit portion has softer mechanical properties than the storage portion, and is a capillary gradient in the direction of the storage portion.
摘要翻译：公开了诸如卫生巾，内裤衬里，成人失禁装置等吸收制品。本文所述的吸收制品包括泡沫吸收结构，其包括相互连接的开放电池的亲水性，柔性的非离子聚合物泡沫结构，其特别适用于吸收血液和血液中的液体。 15分钟后，在31℃下，在0.74psi的围压下测量时，泡沫结构是弹性可压缩的并且具有约5％至约85％的压缩挠曲性。在优选实施例中，泡沫结构在这样的力下是可压缩的，即当它被放置在佩戴者的阴唇之间的空间中时，它将被压缩而不会使穿戴者的大阴唇变形，并且将被穿戴者的阴唇模制并且符合形状其中。吸收结构可以包括采集/配合部分和存储部分，其中采集/配合部分具有比存储部分更软的机械性能，并且是在存储部分的方向上的毛细管梯度。
