Clean operating correctly measuring methods are there? 1, Inner Mongolia clean operating rooms, on the first echelon of the impactor, before the measurement, clean operating room index, the first recording of the initial weight of each level of the skin or the calculated level layer of particles per unit area of ??the original amount. Collision run 10 minutes or longer. At the end of this time period, it is sealed, move to balance or endoscopic department for evaluation. Remove each set level layer, recording the weight or quantity can be collected on each grade level macro particles accumulated particles. Define the macro particle concentration is: the impactor appropriate grade level or amount of the total weight of particles through collisions has been in addition to the total gas flow. Classification and cleansing action principle according to organizational flow clean operating room airflow divided into two categories namely 1, vertical unidirectional flow (laminar flow) clean operating rooms; 2, chaotic flow clean operating room. ● vertical unidirectional flow (laminar flow) clean operating room clean air action principle through efficient filter and plenum pressure even after both flow effect, clean operating rooms warranty, vertically into the operating room. Since both sides of the detention of outlet to return air, the way air flows through a sectional velocity uniform, clean operating room cost, especially the one-way flow line parallel to the work area, no vortex. Clean air like the air piston-like indoor air pollution from return air launch, so the operating room is always kept clean state.
