手术室的室内环境对人员的健康有很大的影响。与居住者释放的污染物相比，手术设备产生的污染物量更大，容易影响患者和医生的健康。在这项研究中，局部排气通风（LEV）应用于手术室，LEV安装在手术区附近，以消除手术设备中的手术烟雾。采用CFD技术，研究了不同进气量和不同LEV进气面积下的手术烟气浓度降低潜力。结果表明，与传统方法相比，当LEV进气面积为0.030 m2时，当进气量从0.003 m3/s增加到0.027 m3/s时，手术烟气浓度可降低10.8%~ 39.2%;当LEV进气量为0.015 m3/s时，当进气面积在0.015 ~ 0.060 m2范围内变化时，手术烟气浓度可降低24.7%~ 31.6%。该研究表明，LEV在降低手术室中的手术烟雾浓度方面具有良好的潜力。关键词：手术室，局部排风，层流，手术烟雾，计算流体力学
The indoor environment of the operating room has a significant impact on the health of personnel. Compared with the pollutants released from occupants, the amount of pollutants generated by surgical equipment is greater, which easily affects the health of patients and doctors. In this study, local exhaust ventilation (LEV) is applied to an operating room and LEV is mounted near the operation zone to remove the surgical smoke from the surgical equipment. CFD technique is used and the surgical smoke concentration reduction potential under different inlet air volumes and different inlet areas of LEV is studied. The results show that compared with the traditional method, when the inlet area of each LEV is set to 0.030 m2, the surgical smoke concentration can be reduced by 10.8%-39.2% as the inlet air volume increases from 0.003 to 0.027 m3/s; when the inlet air volume of each LEV is set to 0.015 m3/s, the surgical smoke concentration can be reduced by 24.7%-31.6% as the inlet area varies from 0.015 to 0.060 m2. This study shows that the LEV has a good potential in reducing surgical smoke concentration in the operating room. Keywords: operating room, local exhaust ventilation, laminar airflow, surgical smoke, CFD
