Add B: The letter ‘B’ stands for ‘Big’ from ‘Big’ sterilizers. In the process of writing the EN 13060 it
was assumed that in Big Sterilizers all medical devices, e.g. wrapped, none wrapped, hollow, non
hollow, porous and none porous, can be sterilized in a big sterilizer. Of course, one has to realize that
the load that to be sterilized is determining the minimum requirements for the process to be used. In
Big sterilizer, it is possible to have type S or type N processes, e.g. for water like medicines in closed
containers it is necessary to have special (type S) process.
Add S: The letter ‘S’ stands for Special, form ‘Special’ or ‘Specified’ products. In these sterilizers the
manufacturer of the sterilizer has to specify what can and cannot be sterilized in this type S process.
Add N: The letter ‘N’ stands for ‘None’, from none wrapped and none hollow. These sterilizers or
sterilizers that cannot sterilize wrapped product. Consequently, the products sterilized have to be
used immediately, or NOT regarded as sterilized but as disinfected.
N 没有真空泵 利用重力置换原理,使热蒸汽在灭菌器中从上而下,将冷空气由下排气孔排出,排出的冷空气,由饱和蒸汽取代,利用蒸汽释放的潜热使物品达到灭菌 不能用于油类、粉剂、空心负载。
B 有真空泵 利用机械抽真空原理,使灭菌器内形成负压,蒸汽得以迅速穿透物品内部。不能用于油类、粉剂、液体。
S 有真空泵 利用脉动蒸汽冲压置换原理,在大气压以上,用饱和蒸汽反复交替冲压,通过压力差将冷空气排出。
