Abstract
A biodegradable, flexible wound covering based on fibrin and a process for its preparation are described, in which a fibrinogen solution is subjected to a single-stage or multistage dialysis, then a flexible fibrin web is formed by action of an aqueous thrombin solution on the fibrinogen solution and this is subsequently subjected to freeze-drying.
Claims7
A process for the production of a flexible wound covering based on fibrin, which comprises:
- subjecting a fibrinogen solution to at least one organic complexing agent in a single-stage or multistage dialysis,
- forming a flexible fibrin web by action of an aqueous thrombin solution on the fibrinogen solution, and
- freeze-drying the flexible fibrin web.
