Embodiment 1
[0031] Example 1 The gelatin sponge for trauma hemostasis is prepared from the main raw materials in the following weight proportions (10 g per part): 3 parts of gelatin, 0.5 part of formaldehyde solution, and 50 parts of water for injection.
[0032] The preparation method of above-mentioned trauma hemostasis gelatin sponge, the steps are as follows:
[0033] (1) Take the gelatin that has been processed into powder and soak it in water for injection for 0.6 hours to make it fully absorb water and swell;
[0034] (2) Heat the expanded gelatin obtained in step (1) on a water bath at 35°C, stir continuously to dissolve, take it out, and cool to 15°C;
[0035] (3) Stir the product obtained in step (2) in a high-speed mixer to produce a large amount of foam, add formaldehyde solution, continue to stir for 0.5 minutes, then pour it into a plastic sand gauze box, put it in a blast chamber, and send it to 26°C The hot air is fully dried to obtain a sponge;
[0036](4) Remove the h...

[0037] Example 2 The gelatin sponge for trauma hemostasis is prepared from the main raw materials in the following weight proportions (15 g per part): 9 parts of gelatin, 2.5 parts of formaldehyde solution, and 150 parts of water for injection.
[0038] The preparation method of above-mentioned trauma hemostasis gelatin sponge, the steps are as follows:
[0039] (1) Take the gelatin that has been processed into powder and soak it in water for injection for 1.5 hours to make it fully absorb water and swell;
[0040] (2) Heat the expanded gelatin obtained in step (1) on a water bath at 55°C, stir continuously to dissolve, take it out, and cool to 30°C;
[0041] (3) Stir the product obtained in step (2) in a high-speed mixer to produce a large amount of foam, add formaldehyde solution, continue to stir for 1.5 minutes, then pour it into a plastic sand gauze box, put it into a blast chamber, and send it to 46°C The hot air is fully dried to obtain a sponge;
[0042] (4) Remove...
Embodiment 3
[0044] Example 3 The gelatin sponge for trauma hemostasis is prepared from the main raw materials in the following weight proportions (20 g per part): 5 parts of gelatin, 1 part of formaldehyde solution, and 80 parts of water for injection.
[0045] The preparation method of above-mentioned trauma hemostasis gelatin sponge, the steps are as follows:
[0046] (1) Take the gelatin that has been processed into powder and soak it in water for injection for 0.8 hours to make it fully absorb water and swell;
[0047] (2) Heat the expanded gelatin obtained in step (1) on a water bath at 40°C, stir continuously to dissolve, take it out, and cool to 20°C;
[0048] (3) Stir the product obtained in step (2) in a high-speed mixer to produce a large amount of foam, add formaldehyde solution, continue stirring for 0.8 minutes, then pour it into a plastic sand gauze box, put it in a blast chamber, and send it to 30°C The hot air is fully dried to obtain a sponge;
