Teflon PTFE electret with 300V to 1500V surfact voltage, disinfected by ultraviolet rays, acted on the ACTT 25923 staphylococci aureus with the concentration of 10 4 for 1 to 24 hours, respectively, then we began to observe the bacteriostasis of the electret.

Objectives The aim of this experiment is to test the bactericidal power outside of the human body of silver-covered urinary catheter with killing ATC 25922 Escherichia coli, ACTT 25923 Staphylococcus aureus, ACTT 27853 Pseudomonas aeruginosa and ATCC 9372 Bacillus subtilis.

目的采用医用橡胶导尿管被覆银后观察对ATCC25922大肠埃希氏菌、ATCC25923金黄色葡萄球菌、ATCC27853绿脓假单胞菌和ATCC9372枯草杆菌黑色变种的体外杀菌作用。
