【摘要】：目的观察邻苯二甲醛内镜模拟现场消毒效果及连续使用稳定性。方法采用载体定量杀菌试验和模拟消毒试验方法,对邻苯二甲醛消毒内镜的效果进行观察。结果用浓度为3 000 mg/L的邻苯二甲醛消毒液,在清洗消毒机设定程序运行总时间25.5 min,或手工清洗全过程18.5 min,对污染在模拟消化内镜载体上的枯草杆菌黑色变种芽孢平均消除对数值均4.0。在清洗消毒机模拟运行条件下,连续使用14 d、累计消毒处理81件胃镜,邻苯二甲醛含量从5 880 mg/L降至3 960 mg/L,该液体处理染菌模拟内镜体仍能符合消毒要求。结论该邻苯二甲醛消毒液在模拟现场条件下,无论消毒机处理或手工处理均能达到规定的消毒要求,在消毒机运行累计81条胃镜,邻苯二甲醛消毒液仍保持在有效浓度范围。
[Abstract]:Objective to observe the efficacy and stability of continuous use of phthalaldehyde under endoscopy. Methods the efficacy of phthalaldehyde disinfection endoscopy was observed by carrier quantitative germicidal test and simulated disinfection test. Results 3 000 mg/L phthalaldehyde disinfectant solution was used. The total running time of the cleaning and disinfecting machine was 25.5 min, or the whole process of manual cleaning was 18.5 min. The average logarithmic value of eliminating spores of Bacillus subtilis var. Niger on the simulated digestive endoscope carrier was 4.0. Under the simulated operation condition of cleaning and disinfecting machine, 81 gastroscopes were treated continuously for 14 days, the content of phthalaldehyde decreased from 5 880 mg/L to 3 960 mg / L, and the simulated endoscopy of the liquid treatment could still meet the requirements of disinfection. Conclusion under the simulated field conditions, the disinfection solution of phthalaldehyde can meet the specified disinfection requirements, and the total number of gastroscopes running in the disinfectant machine is 81, and the disinfection solution of phthalaldehyde is still in the effective concentration range.
