Abstract

Background: For reusable devices and device components, effective reprocessing is essential to prevent nosocomial infections.

Aim: The objective of the study was to evaluate manual cleaning as the first step of reprocessing reusable glass probes of a device for generation of non-invasive physical plasma, in accordance with regulations.

Methods: Two glass probes of the device were contaminated with human blood. For manual cleaning, both probes were cleaned with instrument cleaning agent and instrument brushes. Cleaning efficacy was evaluated by total protein measurement in the rinsing solution.

Results: After manual cleaning of the two test glass probes, no protein from the test contamination with human blood could be detected. Neither the different design of the two probes nor the use of a hard or a soft instrument brush demonstrated any difference.

Conclusion: Our data suggest that manual cleaning of glass probes achieves complete removal of organic contaminants. This should enable safe applications in clinical practice.

有效的人工清洁是非侵入性物理等离子治疗医疗设备玻璃探头再处理的第一步。

背景：目的：本研究的目的是评估人工清洗作为再处理可重复使用的玻璃探针的第一步是否符合法规要求，该探针用于生成无创物理血浆：方法：设备的两个玻璃探针被人体血液污染。为了进行人工清洁，使用仪器清洁剂和仪器刷对两个探针进行了清洁。通过测量冲洗溶液中的总蛋白来评估清洁效果：结果：人工清洗两个测试玻璃探头后，没有检测到人血污染测试产生的蛋白质。两个探针的设计不同，使用硬或软的仪器刷也没有任何区别：我们的数据表明，手动清洁玻璃探针可以完全去除有机污染物。结论：我们的数据表明，手动清洁玻璃探头可完全清除有机污染物，这将使其在临床实践中得到安全应用。
