Abstract
This invention relates to a hemostatic member using chitosan having superior hemostatic activity, and more particularly to a chitosan-based hemostatic member for the cervix, suitable for use through insertion into an affected part upon cervical biopsy or surgery, configured to include a hemostatic pack having a projection at an upper end thereof through tying with a thread so as to form a spherical shape using chitosan nonwoven fabrics having a hemostatic function, wherein the thread contains an X-ray-sensitive material, thereby realizing effective hemostasis of the affected part upon cervical biopsy or surgery.
