Bactericidal medical ultrasonic coupling agent for ultrasonic diagnosis of wound surfaces and preparation method of bactericidal medical ultrasonic coupling agent

The invention provides a bactericidal medical ultrasonic coupling agent for the ultrasonic diagnosis of wound surfaces. The bactericidal medical ultrasonic coupling agent comprises 0.05-3% of carbomer, 1-20% of propanediol, 1-20% of glycerol, 0.1-5% of triethanolamine, 0.01-0.3% of triclosan, 0.05-10% of chitosan oligosaccharide, and 0.05-5% of menthol, the balance being purified water. The bactericidal medical ultrasonic coupling agent is prepared through the following steps: adding carbomer into the purified water, allowing the mixture to stand still overnight to obtain a solution A, fetching propanediol and glycerol through weighing for mixing, adding triclosan, chitosan oligosaccharide and menthol, and fully dissolving the substances to obtain a solution B; and adding the solution B in the solution A, stirring the mixture uniformly, adding triethanolamine, mixing the mixture fully, and obtaining the bactericidal medical ultrasonic coupling agent.
