Powder-type hemostatic composition and preparation method therefor

The present invention relates to a powder-type hemostatic composition and a preparation method therefor and, more specifically, to a powder aggregate obtained by binding biocompatible hemostatic material powders with a binder and having porosity, a preparation method therefor, and a powder-type hemostatic composition. The powder-type hemostatic composition comprises the powder aggregate so as to have improved hemostatic performance compared to simple powder hemostatics and is capable of being applied to a large surface area in need of hemostasis or to a narrow and thin part difficult to approach for conducting hemostasis. 本发明涉及一种粉末型止血剂组合物及其制备方法，更详细地，涉及一种通过将生物相容性止血材料的粉末用粘合剂结合而获得并具有多孔性的粉末聚集体及其制备方法、以及粉末型止血剂组合物，与简单的粉末止血剂相比，所述粉末型止血剂组合物通过包含所述粉末聚集体来提高止血性能，并且可以用于需要大表面积止血的部分或者为了止血而难以接近的窄且细的部分等。
