A degradable hemostatic sponge that can be self-degraded and absorbed by a human body has poly lactic acid as its main material and mixed with a moisture-absorbent material, such as collagen, chitosan, starch and the like, at a specific ratio. Given grinding, mixing and melting steps, the materials using a supercritical fluid as a foaming agent can be used to manufacture the degradable hemostatic sponge having an open-cell microcellular form by a continuous extrusion foaming process. In addition, the present invention also includes a system and a method for manufacturing the degradable hemostatic sponge.
