Example Embodiment
[0042] Example 1.
[0043] A medical biofiber hemostatic powder material composed of the following raw materials in weight percentage:
[0044] Microporous starch 50%
[0045] Puffball spore powder 50%.
[0046] The surface micropore diameter of the microporous starch is 6-15 μm, and the porosity of the microporous starch is more than 90%.
[0047] The puffball spore powder is a puffball spore powder obtained by peeling the outer skin of the puffball, digging out the content to sieve out the spores, drying the spores at 110 degrees Celsius, pulverizing and passing through a sieve of more than 100 mesh.
[0048] The preparation method of the microporous starch includes the following steps:
[0049] Step A: Add water to 100g starch to make starch milk with a mass percentage concentration of 21%, then add 4g sodium chloride, stir evenly, and ultrasonically vibrate for 1 hour;
[0050] Step B: Add 1% sodium trimetaphosphate relative to the starch mass, adjust the pH value to 10, stir evenly, a...
