Document Type and Number:
WIPO Patent Application WO/2022/019467
Kind Code:
A1
Abstract:
The present invention relates to a topical hemostatic powder composition and a preparation method therefor and, more specifically, to a technology of providing a powder-type hemostatic agent which comprises a super absorbent polymer and a bioadhesive polymer (BP) and is biodegradable in vivo and superb in terms of hemostasis effectiveness, thereby finding applications in surgical procedures and minimal invasive surgery such as endoscopy, laparoscopy, etc.
