隔离病房隔离效果的研究（1）
Study on isolation effects of isolation wards (1)
摘要：
从理论上分析总结了影响隔离效果的因素：压差、门的开关、人的进出、温差及缓冲室的设置。建立了实验用单床隔离病房和双床隔离病房，对三种送排风口方案及缓冲室的隔离效果进行了实验研究。指出压差不能抵消其他因素的影响；提出主流区和定向气流是保护医护人员的首要措施；证明床侧和床尾双送风口效果最好；提出用缓冲室稀释、自净、过滤在动态条件下外泄的污染物是最重要的动态隔离措施。
Abstract：
Theoretically analyses and summarizes the influencing factors of isolation effects, including the pressure difference, door opening and closing, passing in and out of persons, temperature difference and buffer rooms. By establishing isolation wards with single bed and double beds, experimentally studies three schemes for supply and exhaust outlet positions and isolation effects of buffer rooms. Indicates that pressure difference can not counteract the effects of other factors, that making main flow region and applying directional air flow are primary measures for protecting doctors and nurses, that the effect is the best when adopting double supply outlets, with one in the bed side and the other in the bed end, that it is the most important dynamic isolation measure for setting buffer rooms to dilute and filtrate pollutants and selfclean.
