Embodiment 1
[0022] A kind of bamboo fiber medical rapid hemostatic gauze, preparation method comprises the following steps:
[0023] (1) Explosive treatment of bamboo fiber: Take 2.2kg of bamboo fiber, put it into a NaOH solution with a pH of 9~10 and soak it at room temperature for 12 hours. Put it into a sealed tank, add a large amount of water vapor to the sealed tank, and heat the inside of the sealed tank simultaneously, so that the bamboo fiber is treated at a pressure of 1.8 MPa for 30 minutes;
[0024] (2) Preparation of rapid hemostatic powder: Take 80g of chitosan and put it into 1.8kg of dilute sulfuric acid solution with a mass concentration of 12%, and add 100g of lauric aldehyde to the dilute sulfuric acid solution, heat up to 80°C and stir for 4h , then drop NaOH solution into the dilute sulfuric acid solution until the pH in the dilute sulfuric acid solution is 5~6, then add 55g of NaOH solution into the dilute sulfuric acid solution 2 SO 3 , after stirring for 3 hours, ...
Embodiment 2
[0028] A kind of bamboo fiber medical rapid hemostatic gauze, preparation method comprises the following steps:
[0029] (1) Explosive treatment of bamboo fiber: Take 2.6kg of bamboo fiber, put it into a NaOH solution with a pH of 9~10 and soak it for 12 hours at room temperature. Put it into a sealed tank, add a large amount of water vapor to the sealed tank, and heat the inside of the sealed tank at the same time, so that the bamboo fiber is treated at a pressure of 1.6MPa for 50 minutes;
[0030] (2) Preparation of rapid hemostatic powder: Take 80g of chitosan and put it into 1.8kg of dilute sulfuric acid solution with a mass concentration of 10%, and add 120g of myristic aldehyde into the dilute sulfuric acid solution, heat up to 80°C and heat and stir 4h, then add NaOH solution dropwise to the dilute sulfuric acid solution until the pH in the dilute sulfuric acid solution is 5~6, then add 60g of NaOH solution to the dilute sulfuric acid solution 2 SO3 , after stirring fo...
Embodiment 3
[0034] A kind of bamboo fiber medical rapid hemostatic gauze, preparation method comprises the following steps:
[0035] (1) Explosive treatment of bamboo fiber: Take 2.8kg of bamboo fiber and put it into Na with a pH of 9~10 2 CO 3 Soak in the solution at room temperature for 12 hours. When soaking, pay attention to immerse the bamboo fibers in the NaOH solution, then pick up and rinse with water until neutral and put them in a sealed tank. Then add a large amount of water vapor to the sealed tank and heat the inside of the sealed tank at the same time. Make bamboo fiber be processed 30min under the pressure of 1.8MPa;
[0036] (2) Preparation of rapid hemostatic powder: Take 60g of chitosan and put it into 1.6kg of dilute sulfuric acid solution with a mass concentration of 16%, and add 85g of decanal to the dilute sulfuric acid solution, heat up to 70°C and heat and stir for 2.5 h, then dropwise add NaOH solution in the dilute sulfuric acid solution until the pH in the dil...
