    层流手术室是医院里需要净化的环境,手术中患者一旦感染,将会带来严重后果。手术感染主要有三种途径,直接接触感染、患者自身感染和空气中的病菌落入伤口导致的感染。层流手术室净化主要采取三种措施控制浮游粒子发生量、迅述有效排除室内已发生的游浮粒子和有效阻止室外粒子进入室内。层流手术室装修净化原理有哪些?
    Laminar flow operating room is the environment that needs to be purified in hospital. Once the patients are infected during the operation, it will bring serious consequences. There are three main ways of surgical infection: direct contact infection, patient's own infection and infection caused by airborne bacteria falling into wounds. There are three main measures to control the occurrence of planktonic particles in laminar flow operating room, to quickly eliminate the occurrence of indoor planktonic particles and to prevent outdoor particles from entering the room. What are the principles of laminar operation room decoration and purification?
    一、层流手术室净化非单向流洁净法则
    I. Non-unidirectional Flow Cleaning Principle for Laminar Flow Operating Room
    这种净化原理是将经过过滤和除菌的干净气流送到层流手术室内,然后在室内扩散,和室内空气进行混合,将相同数量的气流经回风口排出,被排出的气流已经稀释了室内的污染空气,室内污染严重的空气就会被冲淡,终达到平衡状态。
    The principle of this purification is to send the filtered and sterilized clean air to the laminar flow operating room, then diffuse in the room, mix with the indoor air, and discharge the same amount of air through the return air outlet. The exhausted air has diluted the indoor polluted air, and the seriously polluted indoor air will be diluted and eventually reach the equilibrium state.
    二、层流手术室净化空气过滤法则
    2. Laws of Purified Air Filtration in Laminar Flow Operating Room
    空气在进入到手术室之前,要经过初效、中效和的过滤,这是为了控制空气中的微生物及非微生物粒子。初效过滤掉10微米以上微粒和异物,中效过滤掉1-10微米范围内浮游微粒,过滤1微米以下的亚微米级微粒,这是初效和中效过滤不掉的微粒,这也是送风系统中为关键的部分。过滤可以过滤掉微粒、细菌,可以把它看成是无菌的,也是空气中去除浮游菌的好的方法。

    Before entering the operating room, air must be filtered through initial, intermediate and efficient filters in order to control microorganisms and non-microbial particles in the air. Initial filtration of particles and foreign bodies above 10 microns, intermediate filtration of planktonic particles within 1-10 microns, and efficient filtration of sub-micron particles below 1 micron, which is the initial and intermediate filtration of particles, which is also the key part of the air supply system. Efficient filtration can filter out particles and bacteria. It can be regarded as sterile and a good way to remove plankton in the air.
    三、层流手术室净化单向流洁净室法则
    3. Laws of Purifying One-way Flow Clean Room in Laminar Flow Operating Room
    送风面到回风面的过程中,会经过过滤和除菌,气流流经断面的时候不会发生变化,在送风静压箱和过滤器均衡压力和气流的作用下,整个层流手术室净化的断面上的流速都是均匀的,不会产生涡流。干净气流是充满着整个手术室的,而单向流洁净室原理则就是靠推出作用,把室内的脏空气排到室外,进而室内空气得到净化。
    During the process from the air supply surface to the air return surface, it will be filtered and sterilized, and the air flow will not change when it passes through the section. Under the balanced pressure and air flow of the static pressure box and the high efficiency filter, the flow velocity on the section purified by the laminar flow operating room is uniform, and no eddy current will be generated. Clean air flow is full of the entire operating room, and the principle of one-way flow clean room is to push out the role of the indoor dirty air into the outdoor, and then the indoor air is purified.
    净化要达到的净化效果,还需要医院建立科学的人流、物流流程及严格的分区管理,只有这样终才能达到控制微粒污染的效果。
    In order to achieve perfect purification effect, it is necessary for hospitals to establish scientific flow of people, logistics process and strict zoning management. Only in this way can the effect of controlling particulate pollution be achieved.
