Manufacture of wound dressings in the form of a fiber mass, and of suitable fiber mass.

摘要

A fluffy, finely-divided fibrous collagen derived product having hemostatic and adhesive properties sufficient to join together severed biological surfaces in a live warm blooded animal when the product is wet with blood between the surfaces. In the preparation of the product, the swelling of the collagen fibers is controlled during wet processing to prevent hornification upon drying and the recovered dry fibrous product is subjected to a deaggregation treatment to provide a mass having a bulk density of not more than 8 pounds per cubic foot and a surface area of at least 1 square meter per gram.
