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;

Abstract

The invention discloses a gelatin sponge for trauma hemostasis. The gelatin sponge is prepared from the following main active ingredients in parts by weight: 3-9 parts of gelatin, 0.5-2.5 parts of formaldehyde solution, and 50-150 parts of water for injection. The preparation method of the gelatin sponge for trauma hemostasis is simple, and the gelatin sponge for trauma hemostasis is low in manufacturing cost, very obvious in trauma hemostasis effect, and capable of conducting disinfection and hemostasis.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a sponge for trauma hemostasis and a preparation method. Background technique [0002] Trauma refers to external damage to the body or objects caused by blows, collisions from external objects, or erosion by chemical substances. Refers to emotions such as resentment and worry caused by external stimuli. For example, Dong Zhongshu of the Han Dynasty recorded in "Chunqiu Fanlu · Xuntian Zhidao": "Those who are harmonious and happy are born with external beauty; those who are spiritual are born with internal abundance.
