目的探讨采血车的结构对采血区域空气质量的影响。方法对本站使用的由3类大客车改造而成的Ⅰ型(出入口同一门)、Ⅱ型(后门为入口,前门为出口)、Ⅲ型(中门为入口,前门为出口)结构的采血车(均具备献血者筛查、候采、采血、休息和出入口等基本功能),按静态(消毒后,工作前)、动态(工作时间2—4 h)分区域[采血区(a)、候采区(b)、车间区(c)]进行空气培养,将3种结构采血车内的各区空气中的细菌菌落数用q检验进行统计学分析。结果动态时3种结构的采血车内各区域、同一采血车不同区域空气培养细菌菌落数间两两比较差异有统计学意义(P<0.05);静态时3种结构的采血车各区域空气培养细菌菌落数间两两比较差异无统计学意义(P>0.05)。结论采血车内部结构对不同功能区域空气细菌菌落数有明显的影响,设置采血位的最佳区域是距离车门较远且在单位时间里人员流动量最小的位置。
Objective To investigate the effect of the structure of blood collection car on the air quality in the blood sampling area. Methods The type Ⅰ (same entrance), type Ⅱ (the entrance to the back door and the entrance to the front door) and the type Ⅲ (entrance to the center door) and exit from the front door Vehicles (all with basic functions such as blood donor screening, blood collection, rest and entrances and exits) were divided into two groups according to statistic (before disinfection, before work), dynamic (working hours 2-4 h) (B), workshop area (c)] were air-conditioned, and the bacterial colonies in the air in each of the three structural blood collection vehicles were statistically analyzed by q-test. Results There were statistically significant differences in the number of bacterial colonies cultured in air between the three kinds of structures in different regions of the same blood collection vehicle during the dynamic state (P <0.05). In the static state, the air culture There was no significant difference in the number of bacterial colonies between each couple (P> 0.05). Conclusion The internal structure of blood collection car has obvious influence on the number of airborne bacterial colonies in different functional areas. The best area for setting the blood sampling position is the position far away from the car door and the minimum amount of staff flow in unit time.
