LIQUID-LAID, NON-WOVEN, FIBROUS COLLAGEN DERIVED SURGICAL WEB HAVING HEMOSTATIC AND WOUND SEALING PROPERTIES

摘要

Liquid-laid, non-woven, fibrous web having hemostatic and adhesive properties sufficient to seal a wound formed of fibers of ionizable, water-insoluble, partial acid salts of collagen, the web having certain specified absorbency and porosity characteristics. In order to prevent excessive swelling of the fibers with resulting excessive hornification or densification upon drying, it is essential that mixtures of water-miscible organic liquids such as ethanol with specified minor porportions of water be utilized as the slurrying media.
