Abstract

The invention discloses a preparation method of an antibacterial and anti-adhesion medical glue smear straw, which comprises the following steps: S1: mixing 1-methyl-2-vinyl-1H-benzimidazole-4,7-diol and 3,3 Two (2-carboxyloxyethyl) undecyl hydrocarbonate is reacted to obtain vinyl carbonate-based imidazole polycondensate; S2: then ionized modification of vinyl carbonate-based imidazole polycondensate; S3 : Copolymerize octavinyl cage silsesquioxane with allyl diglycol dicarbonate to obtain carbonate-based cage silsesquioxane copolymer; S4: Modified vinyl carbonate The imidazole condensation polymer and the carbonate-based cage-type silsesquioxane copolymer are uniformly mixed, and after being extruded, stretched, cooled and cut, a medical glue smear straw is obtained. The applicator straw of the present invention has excellent antibacterial and anti-adhesion properties, and meanwhile, also has good heat resistance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of smearing straws, in particular to a preparation method of antibacterial and anti-adhesion medical glue smearing straws. Background technique [0002] Medical glue is an emerging medical product that replaces sewing needles. The main component of medical glue is a-cyanoacrylate, which has the fastest polymerization speed in biological tissues. Under the action of anions in wound blood and interstitial fluid, medical glue can quickly polymerize and solidify to form a film and inlay tightly with the wound, which can firmly maintain the apposition state of the wound, and the glue film can prevent blood cells and platelets from passing through. Under the joint action of protein, the broken small blood vessels on the wound surface can be effectively stopped bleeding, while the adhesive film isolates the tissue and bacteria, and also has the effect of anti-infection and protection of the wound surface.
