我院2005-12开始启用层流净化手术室,其内走廊及15个手术间全部采用层流系统进行空气净化。其原理是将一切进入手术间的空气包括新鲜空气及再循环的空气经高效过滤后,由天花板匀速流下,污染空气由回风口过滤出手术室。手术间气压始终高于周围气压,使空气只能单向流动,保证了手术室
Our hospital started to use laminar flow clean operation room from 2005 to December 2005. All the corridors and 15 operation rooms adopted the laminar flow system for air purification. The principle is that all the air entering the operating room, including fresh air and recirculated air, is filtered through the ceiling at a constant speed and the contaminated air is filtered out of the operating room by the air return. Surgery pressure is always higher than the ambient pressure, so that air can only flow in one direction to ensure that the operating room
