摘要

德国卫生当局在 2012 年发布的医疗器械指南中强调了清洁超声探头的重要性,并着重强调了超声探头的验证和可靠性。除了自动化和经过验证的选择外,擦拭消毒等替代性手工方法也因其独立于其他硬件而受到关注。本研究探讨了使用抹布进行手动清洁过程的有效性,解决了罗伯特-科赫研究所提出的关于半关键设备抹布消毒缺乏验证的问题。EQUINOS 彩色擦拭消毒试剂盒在测试的四个探头的所有清洁过程中都发现了润湿间隙。结果表明,在确保表面完全湿润方面存在重大挑战,尤其是在复杂的器械部位,如夹持区域和用于附加活检附件的固定装置,这表明仅靠人工方法可能无法充分降低感染传播的风险(p 值 < 0.0001)。研究得出结论,虽然手动消毒方法是自动再处理的常用替代方法,但仍亟需加强培训,并有可能开发出更有效的手动消毒技术或彩色湿巾,以确保患者安全并符合医疗卫生标准。

Visualization of Effectiveness: The Use of a Set of Colored Cleaning Wipes for Visible Disinfection of Ultrasound Probes
The German health authorities’ guidelines for medical devices in 2012 highlighted the importance of cleaning ultrasound probes, emphasizing their validation and reliability. In addition to automated and validated options, alternative manual methods such as wipe disinfection have gained traction due to their independence from additional hardware. The study examines the effectiveness of a manual cleaning process using wipes, addressing concerns raised by the Robert Koch Institute regarding the lack of validation for wipe disinfection of semi-critical devices. The EQUINOS colored wipe disinfection kit identified wetting gaps in all cleanings across four probes tested. The results indicate significant challenges in ensuring complete surface wetting, particularly in complex device parts such as clip-on areas and fixtures for additional biopsy attachments, suggesting that manual methods alone may not adequately mitigate the risk of infection transmission (p value < 0.0001). The study concludes that while manual disinfection methods are a commonly used alternative to automated reprocessing, there is a critical need for enhanced training and potentially the development of more effective manual disinfection techniques or colored wipes to ensure patient safety and compliance with healthcare hygiene standards.
