Abstract
A covering membrane for medical wound area treatment is disclosed for burns or for preventing adhesion. The covering membrane has a substrate layer including a polymer material as well as collagen particles which have a particle size I of more than 80 μm and are disposed in such a way as to be fixedly embedded in at least some portions of the polymer material of the substrate layer. The covering membrane further relates to a process for manufacturing such a covering membrane.
Claims22
A covering membrane configured for medical wound area treatment including for burns or for preventing adhesion, comprising:
- a substrate layer comprising a resorbable polymer material;
- and
- collagen particles which have an average particle size between 100 μm and 250 μm, where the collagen particles are disposed fixedly embedded in at least some portions of the resorbable polymer material of the substrate layer;
- wherein at least some of the collagen particles bulge over a surface region of the substrate layer surrounding the respective collagen particle or extend away from the substrate layer to form a collagen pole.
