Title:
METHOD FOR MANUFACTURING MEDICAL MATERIAL, MEDICAL MATERIAL, AND ANTI-ADHESION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/136885
Kind Code:
A1
Abstract:
Provided is a method for manufacturing a medical material in which the properties inherent in a polyanionic polysaccharide, which is the raw material, are retained, said medical material having a high stability because the use of a chemical crosslinking agent is not needed, and having a suitable strength and flexibility. This method for manufacturing a medical material has: a step for obtaining a dispersion liquid by dispersing a powder or granulated product of a first polyanionic polysaccharide, which has been water-insolubilized using a treatment liquid containing a first acid anhydride, into an aqueous solution of a water-soluble salt of a second polyanionic polysaccharide; a step for obtaining a dried film by drying the obtained dispersion liquid; a step for obtaining the medical material by water-insolubilizing the obtained dried film using a treatment liquid containing a second acid anhydride.
