Problems solved by technology

However, due to the nature of the above-mentioned starch itself and the above-mentioned process, only low-temperature heating and freeze-drying are used for processing, resulting in the stability of the starch sponge, which in turn leads to poor toughness and elasticity of the starch sponge, and poor water absorption and hemostatic effects.

preparation example Construction

[0031] Such as Figure 1 to Figure 2 Shown, the preparation method of a kind of lotus seed starch-hydrophilic glue composite sponge provided by the invention comprises the following steps:

[0032] Step 1: After mixing the hydrophilic glue and water, let it stand for 5-7 hours to obtain a hydrophilic glue solution;

[0033] Step 2: Add lotus seed starch into the hydrophilic glue solution in step 1, mix, heat and stir at 70-90°C for 4-6 minutes, and then perform high-pressure sterilization to obtain a compound solution;

[0034] Step 3: Refrigerate the compound solution in step 2 for 22-26 hours, then freeze for 22-24 hours, and then freeze-dry to obtain the lotus seed starch-hydrophilic glue composite sponge.

[0035] Specifically, the working principle of the present invention is as follows:

[0036] Potato starch, tapioca starch, waxy corn starch or sweet potato starch with high amylopectin are often used in the prior art as raw materials for preparing starch sponge. The ...

Embodiment 1

[0057] A preparation method of lotus seed starch-hydrophilic glue composite sponge, comprising the following steps:

[0058] Step a: Mix 0.05g of xanthan gum and 100g of water, and let stand for 5-7 hours to obtain a xanthan gum solution;

[0059] Step b: Add 5g of lotus seed starch and 1.5g of glycerin to the xanthan gum solution in step a, then heat and stir at 70°C for 4min, then autoclave for 30min at a pressure of 0.1MPa and a temperature of 121°C to obtain a compound liquid;

[0060] Step c: Refrigerate the compound solution in step b at 2°C for 22 hours, then freeze at -75°C for 22 hours, and then freeze-dry at -81°C to obtain a lotus seed starch-hydrophilic glue composite sponge.

Embodiment 2

[0062] A preparation method of lotus seed starch-hydrophilic glue composite sponge, comprising the following steps:

Abstract

The present invention relates to the field of medical sponges, and aims to provide a lotus seed starch-hydrophilic glue composite sponge and a preparation method thereof, comprising the following steps: Step 1: After mixing the hydrophilic glue and water, let it stand for 5-7 hours to obtain a hydrophilic sponge glue solution; step 2: add lotus seed starch to the hydrophilic glue solution in step 1, mix, heat and stir at 70-90°C for 4-6 minutes, and then perform high-pressure sterilization to obtain a compound solution; step 3: add the compound solution in step 2 Refrigerate for 22-26 hours, then freeze for 22-24 hours, and then freeze-dry to obtain lotus seed starch-hydrophilic glue composite sponge. The lotus seed starch-hydrophilic glue composite sponge prepared by the invention can quickly stop bleeding and has strong toughness.

Description

technical field [0001] The invention relates to the field of medical sponge preparation, in particular to a lotus seed starch-hydrophilic glue composite sponge and a preparation method thereof. Background technique [0002] Surgical operations and trauma will form bloody wounds, during which a large amount of blood will flow out, and timely and effective hemostasis methods are required. Among them, the commonly used means of hemostasis is to apply a biocompatible absorbable hemostatic material on the bleeding wound, and the hemostatic sponge is one of them. Existing commonly used surgical absorbable hemostatic sponges include gelatin sponge and collagen sponge, wherein gelatin sponge has poor hydrophilicity, small blood absorption, poor adhesion, easy to fall off and easy to cause wound infection; while collagen sponge is absorbed slowly by the human body, It has poor mechanical properties and is derived from animal collagen extracts, which can easily cause allergic reactio...
