Embodiment Construction

[0007] The present invention is a dressing preparation method of antibacterial amorphous hydrogel based on biological characteristics, which comprises the following steps: step 1, weighing 1000 grams of water, slowly adding 5 grams to 30 grams of medical grade carboxymethyl in the water at room temperature Sodium cellulose was stirred to make it completely dissolved and left to stand for 2 hours to obtain component A. The particle size of sodium carboxymethyl cellulose was 500-1000 mesh; step 2, weighed 1000 grams of water, and placed in Add 10g-20g of medical-grade sodium alginate into the water and stir quickly for 15-20 minutes to make it completely dissolved and set it aside for later use to obtain component B. The content of glucuronic acid in sodium alginate is more than 20%; Step 3: Weigh 1000 grams of water, add 5-10 grams of medical-grade claw ear glue to the water at room temperature and stir it under high shear to make it completely dissolve and set it aside for late...

Abstract

The invention discloses a dressing preparation method of an antibacterial amorphous hydrogel based on biological properties, which comprises the following steps: step 1, weighing water, adding sodium carboxymethyl cellulose to the water slowly at normal temperature, stirring, completely dissolving the sodium carboxymethyl cellulose, and putting aside to prepare a component A; step 2, weighing water, adding sodium alginate to the water at normal temperature, quickly stirring, completely dissolving the sodium alginate, and putting aside for future use to prepare a component B, step 3, weighing water, adding Saxifraga dshagalensis rubber to the water at normal temperature, stirring at a high shearing speed, completely dissolving the Saxifraga dshagalensis rubber, and putting aside for future use to prepare a component C; step 4, weighing water, adding epsilon-polylysine to the water, slowly stirring, and putting aside for future use to prepare a component D; and step 5, mixing the component A, the component B and the component C together, stirring at the high shearing speed, slowly stirring so that the components A, B and C are dissolved mutually, and slowly adding the component D, adequately dissolving the component D to form a gel, sterilizing and packaging in a bottle for use.

Description

technical field [0001] The invention relates to a dressing preparation method of an antibacterial amorphous hydrogel based on biological characteristics. Background technique [0002] At present, in the clinical practice of wound care, ordinary degreasing gauze, microporous film, etc. are used to care for the wound. This method tends to make the wound dry, which greatly affects the progress of wound healing, and may produce a lot of of scars. Contents of the invention [0003] The invention provides a dressing preparation method based on biological characteristics and antibacterial amorphous hydrogel. The prepared dressing can stop bleeding, sterilize, promote wound healing, and reduce scars. [0004] The present invention adopts the following technical scheme: a dressing preparation method based on biological properties of antibacterial amorphous hydrogel, which includes the following steps: Step 1, taking water, slowly adding sodium carboxymethyl cellulose to the water ...
