摘要： 目的 评估过氧化氢雾化消毒机对血液运输车车厢消毒效果。方法 采用过氧化氢雾化消毒机对车厢内部进行消毒,检测车厢内部自然环境空气菌落、嗜热脂肪杆菌（ATCC12980）芽孢菌片和车厢内左右两侧和靠近驾驶室内壁的中心点、车厢内部门把手位置、内置制冷机组四周中心的表面菌落数的检测,评价消毒效果。结果 消毒后车厢内部自然环境空气菌落和物体表面菌落数均合格且灭杀对数值均>1.00,嗜热脂肪杆菌（ATCC12980）芽孢菌片的灭杀率为100%,消毒后仅内门把手和内置制冷机组靠近驾驶室（前）检测到细菌,菌落中位数分别为4.21 CFU/cm2（范围为0 CFU/cm2~6.84 CFU/cm2）和6.84 CFU/cm2（范围为0 CFU/cm2~8.42 CFU/cm2）,其余检测位置均无菌生长。过氧化氢雾化消毒机人工操作时间的中位数为45 s（范围为40 s~51 s）,常规消毒喷雾所需人工操作时间的中位数为610 s（范围为605 s~613 s）。结论 采用过氧化氢雾化消毒机消毒能满足空气菌落及车厢内部物体表面的消毒要求,提高工作效率,增加安全性。

Abstract: Objective To evaluate the disinfection effect of bloodmobile carriage (hereinafter referred to as "carriage") by hydrogen peroxide mist disinfection machine. Methods After using a hydrogen peroxide mist disinfection machine to disinfect the interior of the carriage, we evaluated the disinfection effect by testing the natural environmental air microbial counts inside the carriage, the Bacillus stearothermophilus (ATCC12980) tablets, as well as the number of surface colonies on the left and right sides of the carriage, near the interior wall of the driver's cabin, the handle positions, and around and in the center of the built-in refrigeration unit. Results After disinfection, the air colonies and surface colonies inside the carriage were qualified and the logarithmic value of extermination was >1.00, and the killing rate of Bacillus sphaericus (ATCC12980) was 100%, only the bacteria were detected in the inner door handle and the built-in refrigeration unit close to the cab (front)with the median colony counts 4.21 CFU/cm2 (range: 0 CFU/cm2~6.84 CFU/cm2) and 6.84 CFU/cm2 (range: 0 CFU/cm2~8.42 CFU/cm2), respectively, and the rest of the detected locations were free of bacterial growth. The median manual operation time of hydrogen peroxide mist disinfection machine was 45 s (range: 40 s~51 s), and the median of manual operation time required by conventional disinfection spray was 610 s (range: 605 s~613 s). Conclusion The use of a hydrogen peroxide mist disinfection machine can meet the disinfection requirements for air colonies and the surface of objects inside the carriage, improve work efficiency and increase safety.
