Abstract

The invention discloses a medical adhesive, which belongs to the technical field of medical polymer materials. The present invention adopts the following raw materials: polyacrylate, water-soluble phenolic resin, cowhide paste, Panax notoginseng, Zizhucao, sulfonated lignin, glycerol triabbietate, hydroquinone and deionized water; Concentrate and Asteraceae extract concentrate; mix water-soluble phenolic resin with deionized water, then add polyacrylate to mix, then add sulfonated lignin, glycerol triabietate, hydroquinone, and then add three Stir the Seven Extract Concentrate and the Purple Pearl Grass Extract Concentrate well. In the present invention, on the basis of the conventional formula of the original medical adhesive, adding cowhide plaster, Panax notoginseng, and purple pearl grass, and utilizing the active ingredients contained therein, the bonding strength of the finished medical adhesive is improved, and the curing speed thereof is accelerated. Therefore, the existing medical adhesives have the problems of too long curing time and insufficient bonding strength due to imperfect formulas.

Description

Technical field [0001] The invention belongs to the technical field of medical polymer materials, and particularly relates to a medical adhesive. Background technique [0002] The use of medical adhesives has a long history, but it has not been rapidly developed until recent decades. In 1936, the German Kulzerr company listed a dental adhesive with methyl methacrylate (MMA) as the main body. In 1959, a quick adhesive with α-methyl cyanoacrylate as the main body came out in the United States, thus realizing the revolution of surgical operation from stitching to direct bonding. [0003] Medical adhesives are mainly used in various surgical operations such as traumatic wounds, plastic surgery, family planning, etc. It has the functions of fast bonding to human biological tissues and promoting wound healing, and can partially replace wound sutures. However, although medical adhesives have the advantages described above, due to the imperfect formulation of the existing medical adhesiv...
