Adhesion preventive membrane, method of producing a collagen single strand, collagen nonwoven fabric and method and apparatus for producing the same |
摘要 |
An adhesion preventive membrane including a nonwoven fabric layer of collagen fibers, having on a surface thereof a coating layer containing a mixture of collagen and hyaluronic acid, or a method of producing a continuous collagen single strand, wherein a strand-like collagen is dehydrated/coagulated in a hydrophilic organic solvent having a water content of about 10% or less and then dried under conditions of a relative humidity of about 50% or less and a temperature of about 42° C. or less. A collagen nonwoven fabric of first and second layers composed of a plurality of collagen strand-like materials spun out of a solubilized collagen solution, and arranged in parallel, the first and second layers being laminated and bonded to each other so that directions of arrangements of the strand-like materials of the first and the second layers are at an angle therebetween.
