SHIELDING MEMBRANE FOR INDUCTION OF TISSUE REGENERATION AND METHOD FOR PRODUCING THE SAME

摘要

PURPOSE: Provided is a shielding membrane for induction of tissue regeneration which has an excellent effect of shielding invasion of epithelial cells and bonding tissues, help a bone tissue to grow and can be conveniently designed in an operation, and a method for producing the same. CONSTITUTION: The shielding membrane comprises two sheets of chitosan non-woven fabric and a porous bio-degradable polymer membrane disposed therebetween. The bio-degradable polymer is formed of bio-degradable polyester polymer such as polylactic acid, polyglycolic acid, polylactic acid-glycolic acid copolymer and polycaprolactone. The bio-degradable polymer membrane has a thickness of 0.01 to 10 mm. The chitosan non-woven fabric includes a foreign substrate ingredient to improve bio-compatibility, a ceramic ingredient to improve the mechanical strength and bone tissue regeneration or a mixture thereof.
