National experts consensus on clinical application of collagen-based wound biomaterials (2018 version)

Collagen, as the main structural protein in human body, plays an important role in the wound healing process. Due to their inherent hemostatic characteristics, good biocompatibility, low immunogenicity, as well as controllable biodegradability, collagen-based materials have attracted much attention. In this article, we mainly introduce the characteristics of collagen-based wound biomaterials and the application mechanism as scaffold and wound dressing. And the standard and unified experts′ consensus formed on the clinical indications, recommended applications, contraindications, and matters needing attention. The consensus wound help clinicians and patients to recognize collagen-based wound biomaterials correctly and use them rationally.
