新型医用材料床垫清洗消毒干燥效果评价方法研究

目的评价新型医用材料床垫清洗消毒干燥效果。方法参考《消毒技术规范》(2002版)和《医用清洗剂卫生要求(报批稿)》,建立医用床垫材料清洗消毒干燥效果评价试验方法。采用目测法和残留蛋白测定法判定清洗效果,细菌计数法判定消毒效果,称重法判定干燥效果。结果该床垫载体通过特定流程后,采用目测法和残留蛋白测定法判定清洗效果,其合格率均为100%,清洗后的床垫载体无变形;污染床垫载体在两种消毒剂中浸泡15 min,消毒效果合格且无变形;带水床垫载体悬挂晾干1.5 h后,水分残留率为0.24%。结论该新型材料床垫可初步满足整体清洗消毒干燥的要求,为医用床垫的清洗消毒开辟新途径;但其现场清洗消毒效果、材料耐洗程度、成本效益等方面有待进一步研究与验证。

Evaluation method of cleaning, disinfection and drying effect of new material medical mattress

Objective To evaluate efficacy of cleaning, disinfection and drying of new material medical mattress. Methods Referring to the Disinfection Technical Specifications (2002 version) and Hygienic Requirement for Medical Detergent (revision for approval), a test method for evaluating the efficacy of cleaning, disinfection and drying of medical mattress materials was established. Cleaning efficacy was determined by visual observation and residual protein detection method, disinfection and drying efficacy were determined by bacterial counting method and weighing method respectively. Results After the mattress carrier passed through a specific process, the qualified rates of cleaning efficacy were both 100% by visual observation method and residual protein detection method, mattress carrier after cleaning was not deformed, the contaminated mattress carrier was immersed in two disinfectants for 15 minutes, disinfection efficacy was qualified without deformation; water residue rate was 0.24% after hanging water mattress carrier for 1.5 hours. Conclusion The new material mattress can meet the requirements of overall cleaning, disinfection and drying, it opens up a new way for cleaning and disinfection of medical mattress, but on-site cleaning and disinfection efficacy, material washing resistance and cost-effectiveness need further research and verification.
