概括
擦拭器系统和准备使用 (RTU) 擦拭器的错误加载可能会影响消毒剂溶液 (DS) 的输送. 适当的装载和储存对于医疗保健机构的有效表面消毒至关重要.
科学领域:
- 感染控制
- 医疗卫生
- 消毒技术
背景情况:
- 在医疗保健机构中,可重复使用的布被擦拭器系统和准备使用 (RTU) 擦拭器所取代.
- 表面消毒的有效性取决于消毒溶液的正确应用.
- 擦拭系统的不当使用可能会损害消毒效果.
研究的目的:
- 评估错误加载对擦拭器系统中消毒剂溶液 (DS) 的影响.
- 评估使用准备 (RTU) 巾片的DS输送的一致性.
- 在医疗环境中确保最佳的表面消毒方法.
主要方法:
- 用于视觉检查和摄影记录的消毒剂溶液 (DS) 装载在擦拭器系统中.
- 用两个RTU擦拭产品 (流量包和站立袋) 的重力度分析评估了擦拭和DS输送.
- 在经过定义的擦拭方案后评估了表面覆盖面.
主要成果:
- 与分剂系统中的圆形加载相比,基于酒精的DS输送在不正确的 (水平/垂直) 加载下降.
- 释放氧气的DS分配器显示了减少的残留体积和更低的输送与不正确的装载.
- RTU流量包需要倒置存储以保持均的湿; 站立袋需要丢弃第一个擦拭.
结论:
- 制造商指令加载擦拭器系统 (循环加载) 和RTU擦拭存储 (流量包的倒置) 对于一致的DS交付至关重要.
- 必须遵守特定的规则,例如从立式袋中丢弃第一张纸巾.
- 对于所有RTU产品,制造商应提供有关擦拭消毒的有效范围的标准化信息.

01:30Cleaning, Sterilization, and Disinfection
7.3K
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
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...

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
