▎ 摘 要
NOVELTY - A medical ultrasonic coupling agent, comprises 20-30 pts. wt. carbomer, 10-15 pts. wt. ethylene diamine tetra acetic acid disodium salt (EDTA 2Na), 5-10 pts. wt. chitosan agent, 4-8 pts. wt. ortho-phthalaldehyde modified antibacterial agent, 1-3 pts. wt. sodium hydroxide, 35-45 pts. wt. deionized water, 2-5 pts. wt. glycerol. USE - Medical ultrasonic coupling agent. ADVANTAGE - The ultrasonic coupling agent is matched with the EDTA-2Na by using carbomer, by adding chitosan modifier, ortho-phthalaldehyde modified antibacterial agent to improve the antibacterial effect of the product, the chitosan agent is modified by the modified graphene, which improves the stability of the modified antibacterial agent with ortho-phthalaldehyde, to synergistically enhance the antibacterial performance of the product, antibacterial stability, to improve the antibacterial effect and quality level. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparation of the medical ultrasonic coupling which involves adding carbomer, EDTA-2Na sequentially to the deionized water, then adding propanetriol to obtain the mixed material, then adding the chitosan agent, the ortho-phthalaldehyde modified antibacterial agent dispersing stirring treatment, stirring fully, finally adding sodium hydroxide, adjusting pH value to obtain medical ultrasonic coupling agent.
