Method for the preparation of collagen membranes for haemostasis, wound treatment and implants |
| abstract |
The invention relates to a process for the production of collagen membranes for medical purposes, in which the collagen raw materials from beef or pork collagen are mechanically freed from fat residues, treated with dilute alkalis and acids and optionally enzymes, washed thoroughly between these steps and thereby accompanying the collagen raw material Cleans impurities and processes them to obtain a collagen matrix with a dry-dry weight of about 25% by weight. Collagen membranes are obtained in which the native integral connection has been preserved and a fast hemostatic effect results, which are also supple and adhere well to the surface of a wound. |
