【摘要】：目的观察不同清洗消毒方法对医院空调通风系统清洗消毒效果,为选择最佳的清洗消毒方法提供依据。方法通过细菌定量检测方法,观察擦拭法、刷洗法和刷洗+消毒剂擦拭法对某医院空调系统出风口和回风口过滤网清洗消毒效果。结果采用毛巾沾清水擦拭清洗后细菌总数超标率为93.5%,金黄色葡萄球菌和表皮葡萄球菌检出率分别为100.0%和57.1%;采用流动水刷洗空调过滤网后细菌总数超标率为90.3%,金黄色葡萄球菌和表皮葡萄球菌检出率分别为64.3%和28.5%。采用流动水刷洗后,分别用500 mg/L含氯消毒剂、1 000 mg/L苯扎溴铵、5 g/L过氧乙酸溶液擦拭的过滤网表面细菌总数均5 cfu/cm2,全部达到消毒合格要求。结论医院空调系统出风口和回风口过滤网应当在拆卸并用流动水刷洗后,再用消毒剂溶液擦拭方可达到消毒效果要求。
[Abstract]:Objective to observe the effect of different cleaning and disinfection methods on air conditioning and ventilation system in hospital, and to provide the basis for selecting the best cleaning and disinfection methods. Methods by means of quantitative bacterial detection, the cleaning and disinfection effects of wiping method, brushing method and brushing disinfectant method on air outlet and air outlet filter net of air conditioning system in a hospital were observed. Results after cleaning with clean water, the total bacterial count exceeded the standard rate was 93.55.The detection rate of Staphylococcus aureus and Staphylococcus epidermidis were 100.0% and 57.1% respectively, and the total bacterial count exceeded the standard rate of 90.3% and golden yellow after washing air conditioning filter net with flowing water. The detectable rates of staphylococcus chromostaphylococcus and Staphylococcus epidermidis were 64.3% and 28.5%, respectively. After brushing with flowing water, 500 mg/L chlorinated disinfectant 1 000 mg/L benzalkonium bromide 5 g / L peracetic acid solution was used to wipe the total bacteria on the surface of the filter net, all of which met the requirements of disinfection. Conclusion the air outlet and air return filter should be disassembled and washed with flowing water, and then wiped with disinfectant solution to achieve the disinfection effect.
