The absorbent product can include a liquid permeable pouch, and at least one sheet of absorbent material within the liquid permeable pouch. The instructions can include rolling and/or folding the absorbent product, placing the rolled and/or folded absorbent product proximate the site of the bleeding, and applying pressure to the absorbent product. The instructions can also include inserting the absorbent product into a mucous membrane, such as a nostril or the vaginal canal. Methods of utilizing the absorbent product and the kit are also disclosed.

The present disclosure relates to a collagen-alginate wound dressing, including a matrix in which a low-molecularized collagen and a low-molecularized alginate are crosslinked and a method of preparing the same.

This invention relates to a polymer composition containing at least one polymer and at least one agent, formed bodies having such a polymer composition, the use of the formed bodies and polymer compositions, and corresponding threads, nonwoven materials, clothing articles, and medical aids.

One embodiment of the present invention provides a nonwoven fabric containing silk fibers in which an abs intensity ratio [abs (1650)/abs (1620)], which is a ratio of an intensity of a peak positioned in a vicinity of 1650 cm.sup.−1 [abs (1650)] in an infrared absorption spectrum to an intensity of a peak positioned in a vicinity of 1620 cm.sup.−1 [abs (1620)] in an infrared absorption spectrum, is larger than 0.65 and 1.90 or less, and a method for producing the nonwoven fabric containing silk fibers.
