【摘要】：目的研究含氯消毒剂和过氧乙酸对内镜部件和金属的腐蚀性,为内镜消毒剂的选择提供参考。方法采用称重法和目测法,观察一种络合氯消毒剂对内镜部件和金属片的腐蚀性,并用过氧乙酸作平行比较。结果该络合氯消毒剂和过氧乙酸消毒剂使用液对手柄连接部、按钮、导光缆密封圈、弯曲橡皮、导光缆插入部、手柄、塑料管和插入管外套的失重值无明显差别。有效氯4 000 mg/L的该络合氯消毒剂对不锈钢、碳钢和铜为基本无腐蚀性,对铝具轻度腐蚀性;含量为2 643 mg/L某过氧乙酸消毒剂对不锈钢、碳钢基本无腐蚀,对铝、铜分别具轻度和重度腐蚀性。结论该络合氯消毒剂对内镜部件和四种金属片腐蚀性均比较低,其对金属的腐蚀性明显低于过氧乙酸消毒剂。
[Abstract]:Objective to study the corrosion of chlorine containing disinfectant and peracetic acid on endoscopic components and metals, and to provide reference for the selection of endoscopic disinfectants. Results the complex chlorine disinfectant and peracetic acid disinfectant were used to connect the handle, button, optical guide cable sealing ring, bending rubber, optical guide cable insertion part, handle, There is no significant difference in weight loss between the plastic tube and the casing inserted into the tube. The chlorine complex disinfectant with available chlorine 4 000 mg/L is basically non-corrosive to stainless steel, carbon steel and copper, and slightly corrosive to aluminum; A peracetic acid disinfectant containing 2 643 mg/L had little corrosion on stainless steel and carbon steel, mild and severe corrosion on aluminum and copper, respectively. Conclusion the complex chlorine disinfectant is less corrosive to endoscope parts and four metal sheets. Its corrosion to metal is obviously lower than peracetic acid disinfectant.
