目的研究新出厂医疗器械清洁方法并进行清洁质量评价。方法通过目测法对手工清洗和机械清洗质量进行了评价。结果新出厂医疗器械表面均存在保护油,部分器械存在颗粒物质。表面光滑、无齿缝和关节的器械手工清洗法和机械清洗法均可达到清洁度要求,而结构复杂的器械需要反复清洗和高温处理方可达到清洁度要求。结论新出厂手术器械表面油污严重,必须经过有效清洗和反复高温灭菌之后才能达到清洁度要求。
Objective To study the cleaning methods of new factory medical devices and evaluate the quality of cleaning. Methods The manual cleaning and mechanical cleaning quality were evaluated by visual inspection. Results The new ex-factory medical devices had protective oil on their surfaces and some of the instruments were particulate. Surface smooth, toothless and joint instruments manual cleaning method and mechanical cleaning method can meet the requirements of cleanliness, and complex structure of the device requires repeated cleaning and high temperature treatment to achieve cleanliness requirements. Conclusion The surface of the new ex-factory surgical instrument has serious oil stains, which must be cleaned effectively and repeatedly sterilized before it can meet the cleanliness requirements.
