Embodiment 1
[0022] Absorbable hemostatic sponge, the preparation method is:
[0023] (1) Put 55g of gelatin in an enamel pot or a stainless steel pot, add 480ml of distilled water, let stand to make the gelatin absorb water and swell, put the swelled gelatin in a water bath at 60°C to melt, and set aside;
[0024] (2) Put 15-20g tragacanth gum in an enamel pot or a stainless steel pot, add 200ml of distilled water, let it stand still to make the tragacanth gum absorb water and swell, and put the expanded tragacanth gum in a water bath at 70°C to dissolve it. spare;
[0025] (3) Mix the melted gelatin and the melted tragacanth gum evenly, add them into the foaming barrel, then add 100ml of distilled water, 2.5g of hydroxypropyl methylcellulose, and 5.1g of sodium alginate into the foaming barrel , Poria cocos polysaccharide 8.6g, dioctyl sodium sulfosuccinate 4ml, mix and heat up to 80°C, keep for 10 minutes, then cool down to 50°C, keep for 30 minutes, and finally let cool to 29°C;
