The invention relates to the field of medical instruments, and particularly relates to preparation of microporous hemospheres. The method comprises the following steps: pretreating starch, conducting ray irradiation of certain dose, extracting with absolute ethyl alcohol and drying to obtain solid powdery microporous hemospheres. According to the preparation, a cross-linking agent is not used, and the microporous hemospheres also have high water absorption and excellent degradation rate, and are simplified in technology, safe and non-toxic, and more environment-friendly. |
