Manufacturing biocompatible collagen membrane used in medicine and dentistry, involves using raw material selected from natural tissues rich in collagen of cattle and pigs

NOVELTY – Biocompatible collagen membrane manufacturing involves using raw material selected from natural tissues rich in collagen of cattle and pigs. The selected raw material is cleaned by mechanical cleaning process to remove residual material. The cleaned material is treated by using lipase and detergent at 50- 65 degrees C in hydrochloric acid to promote removal of fat tissues. USE – Method for manufacturing biocompatible collagen membrane used in medicine and dentistry (claimed). ADVANTAGE – The method enables to manufacture the biocompatible collagen membrane having improved tensile strength greater than the available similar products in the market in a cost-effective manner. The manufactured membrane can be more easily manipulated and sutured in required areas. DESCRIPTION OF DRAWING(S) – The drawing shows a schematic longitudinal view of a porcine small intestinal submucosa.
