▎ 摘　　要

NOVELTY - Medical conductive paste comprises 0.01-0.05 pts. wt. nano conductive material, 50-150 pts. wt. moisturizer, 1000 pts. wt. phosphate buffer solution, 50-100 pts. wt. viscous agent, 10-20 pts. wt. surfactant, 5-10 pts. wt. sterilizing component and 50-100 pts. wt. gel. The nano conductive material is selected from nano graphene oxide, nano graphene, carbon nano tube and nano aluminum hydroxide, the gel is selected from hyaluronic acid gel, aluminum hydroxide gel and aluminum phosphate gel, and the pH value of the phosphate buffer solution is 6.5-7.5. USE - Medical conductive paste for acquiring electrocardio, myoelectricity and electroencephalogram signals of adults, infants and fetuses. ADVANTAGE - The conductive paste has good biocompatibility, excellent conductivity, strong anti-interference performance and excellent disinfection and bacteriostasis performance, and good application prospect in human electrophysiological signal collection. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing medical conductive paste, which involves: mixing a phosphate buffer solution and a nano conductive material, and performing ultrasonic homogenizing and dispersing to prepare a homogeneous suspension; mixing the homogeneous suspension with a moisturizer, a surfactant and a disinfecting component, and carrying out homogeneous dispersion to form a stable-phase oil-water mixed solution; mixing the oil-water mixed solution, the gel and the viscous agent, and grinding and stirring to prepare a paste; and cooling the paste at 2-8℃ to obtain the medical conductive paste.
