自动化的紫外线-C (UV-C) 光器件显著减少了内镜装置表面的细菌污染. 这项技术可以通过降低病原体传播风险,帮助预防与医疗保健相关的感染 (HAI).
科学领域:
- 感染控制 感染控制
- 微生物学 微生物学
- 环境卫生环境卫生
背景情况:
- 内镜单位是医院关键护理中心和医疗保健相关感染 (HAI) 的潜在地点.
- 共享的表面和非医疗设备,如键盘,越来越多地涉及病原体的传播.
- 该研究调查了自动化UV-C光消毒在减少学术内镜单位的生物负担方面的有效性.
研究的目的:
- 评估自动低强度UV-C光消毒对降低住院内镜单位生物负担的影响.
- 为了确定UV-C光装置是否可以进一步减少超出标准清洁协议的微生物污染.
- 评估UV-C光技术在缓解HAI无声传播方面的潜力.
主要方法:
- 在实施自动化UV-C发光器件之前和之后,对高触摸/公共面进行了生物负担测量.
- 自动设备被动监测和消毒的目标表面使用紫外线-C (UV-C) 光.
- 这项研究的重点是学术内镜单元设置.
主要成果:
- 基线细菌污染在键盘等高触摸场所超过80%,在手术室和公共区域超过57%.
- 在引入自动化UV-C光消毒后,在高触摸表面和手术室内,生物负担平均减少了91%以上.
- 在内镜单元内的各种表面上观察到微生物负荷的显著减少.
结论:
- 在非无菌的患者护理区域的高触摸表面可能存在大量的细菌污染,这有助于无声的HAI传播.
- 被动的,自动化的UV-C光消毒装置有效地减少了内镜单元内识别的表面上的生物负担.
- 在临床环境中,UV-C光技术的实施显示出减少患者之间的HAI传播的前景.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
