Evaluating and Optimally Designing Cleanliness of a Mobile Operating Room

  • 摘要: 移动手术方舱是进行应急救援任务的重要组成部分,因此有必要对手术方舱在紧急情况下的洁净性能进行评估和改善。首先对工况下某型号手术方舱的气流组织和悬浮颗粒浓度展开实验与仿真工作,验证仿真流程的准确性与可靠性。基于已验证的计算流体动力学(CFD)气流组织计算结果,对送风口进行结构优化分析。结果表明,送风量一定的情况下,送风口的形状对手术区域的洁净性能有很大影响。通过送风方式的改进,手术区域的洁净性能得到了明显提升。这对于评价紧急情况下移动手术方舱的洁净性能以及降低病人术后感染率具有重要意义。
