  • 百级层流手术室净化生产应该注意哪些?
    来源:http://www.jnyhrs.com 浏览: 发布日期:2020-09-18
    1).严格净化
    1) Strict purification
    各手术室空气净化系统在手术室墙面四角、净化机组、天花板、走廊、新风机、排风机都设有不同级别的过滤器,并对其进行定期清洁、维修和更换,严格保证室内空气的无菌;另外,层流手术室的卫生管理工作除了日常清洁工作和过去一样,不能有丝毫放松,还对室内的清洁工作有特殊的要求,室内墙角全部为弧形结构设计,找不到任何一个90°的墙角,使细菌无处藏身,避免了清除不尽的死角,并且室内无须使用物理或化学方法进行消毒,这样既节省劳动又防止外来污染的进入。
    The air purification system of each operating room is equipped with different levels of filters in the four corners of the operating room wall, purification unit, ceiling, corridor, fresh air fan and exhaust fan, which are regularly cleaned, repaired and replaced to strictly ensure the sterility of indoor air. In addition, besides the daily cleaning work of laminar flow operating room, it is not allowed to relax at all There are special requirements for indoor cleaning work. All interior corners are arc-shaped structure design, and no 90 ° corner can be found, which makes bacteria have no place to hide and avoid endless dead corners. In addition, there is no need to use physical or chemical methods for indoor disinfection, which can save labor and prevent the entry of foreign pollution.
    2).正压通气
    2) . positive pressure ventilation
    层流手术室不仅要求高度洁净的空气(进入手术室的空气首先须经过滤器净化),而且要求能控制气流的流通方向(即采用层流超净装置),手术室内形成正压环境,使气流从洁净度高的手术区域流向洁净度低的区域,一股细小、薄层的气流,以均匀的流速向同一方向输送,并带走和排出气流中的尘埃颗粒(尘粒)和细菌。目前,层流手术室分为垂直层流式和水平层流式两种。垂直层流式(Supply air ceiling for operating theatre)过滤器装在手术病床的正上方,气流垂直吹送,回风口设在墙面的四角,确保手术台洁净度达标,一般多采用垂直层流式效果较好。广州现代医院正是采用的这种垂直的层流式,在手术室内的顶部还设置了一个吊塔式的负压吸引系统,将医生在手术时呼出的空气吸出塔外,进一步保证手术室的洁净和无菌,降低手术的感染率。
    Laminar flow operating room not only requires highly clean air (the air entering the operating room must be purified by a filter first), but also can control the flow direction of air flow (that is, using laminar flow ultra clean device). A positive pressure environment is formed in the operating room to make the air flow from the high cleanliness operation area to the low cleanliness area, and a small thin layer of air flow can flow to the same area with uniform velocity Direction transport, and take away and discharge the dust particles (dust particles) and bacteria in the air flow. At present, laminar flow operating room is divided into vertical laminar flow and horizontal laminar flow. The supply air ceiling for operating theatre filter is installed on the top of the operating bed, and the air flow is vertically blown. The air return port is set at the four corners of the wall to ensure the cleanliness of the operating table up to the standard. Generally, the vertical laminar flow filter has better effect. Guangzhou modern hospital adopts this vertical laminar flow type, and a hanging tower type negative pressure suction system is set at the top of the operating room to suck the air exhaled by doctors out of the tower during operation, so as to further ensure the cleanliness and sterility of the operating room and reduce the infection rate of the operation room.
    3).单通道流向
    3) . single channel flow direction
    医院在层流手术室与消毒柜之间制作了一堵墙,并设立进、出单通道,需消毒的物品经过“输出”通道直接从手术室转移到消毒柜,消毒后经过“输入”通道转移到手术室,这样避免了消毒物品在转移的过程中二次污染。
    无菌室装修
    The hospital made a wall between the laminar flow operating room and the disinfection cabinet, and set up a single channel for entering and leaving. The articles to be disinfected were directly transferred from the operating room to the disinfection cabinet through the "output" channel, and then transferred to the operating room through the "input" channel after disinfection, so as to avoid the secondary pollution of the disinfection articles in the transfer process.

    层流手术室的日常维护管理
    Daily maintenance and management of laminar flow operating room
    手术室日常的管理:每天用稀释的洗洁精拖净地板,擦洗墙面、通风道、回风口及其他物品表面,每周用含氯消毒水拖净地板、擦洗墙面、通风道、回风口及其他物品表面(有效氯浓度500mg/L)。初级过滤网每月更换,中级过滤网每季更换,过滤网每半年请人员对送风量、噪音、室内正压检测1次,定期对净化系统的设备设施进行维修保养,根据手术量及人流情况1~2年更换1次。
    Daily management of operating room: clean the floor with diluted detergent every day, scrub the surfaces of walls, ventilation ducts, return air outlets and other objects, and mop the floors, walls, ventilation ducts, return air outlets and other objects with chlorine containing disinfectant water every week (effective chlorine concentration is 500mg / L). The primary filter screen shall be replaced monthly, the intermediate filter screen shall be replaced every quarter. The filter screen shall be inspected once every half a year by professional personnel to detect the air supply, noise and indoor positive pressure. The equipment and facilities of the purification system shall be maintained regularly, and shall be replaced once every 1-2 years according to the operation volume and flow of people.
    定期监测:每月对手术室空气、手术人员的手、物体表面进行1次细菌培养。以保证达到规定的空气中细菌总数≤10cfu/m3的环境要求;物体表面细菌总数达到≤5cfu/cm2
    Regular monitoring: the air in the operating room, the hands of operators and the surface of objects were cultured once a month. To ensure that the total number of bacteria in the air is less than or equal to 10 CFU / m3, and the total number of bacteria on the surface of the object is less than or equal to 5 CFU / cm2

    医院层流手术室建设合理规划
    Reasonable planning of laminar flow operating room construction in hospital
    随着现代医疗水平的提高,层流手术室在中小医院普及率越来越高;根据小编收据相关数据显示,在医院建设中部分医院在层流手术室的规划方面欠缺经验,在控制建设成本的同时把手术室这一重要科室建设淡化了,导致竣工后验收流程不合格、使用材料不达标、净化等级不对称等一系列问题;反而还为后续改造增加施工难度,造成相应经济、人力资源损失。
    With the improvement of modern medical level, the popularization rate of laminar flow operating room in small and medium-sized hospitals is getting higher and higher. According to the relevant data of small receipts, some hospitals lack experience in the planning of laminar flow operating room in hospital construction. While controlling the construction cost, the construction of operating room, an important department, is weakened, resulting in unqualified acceptance process after completion, substandard materials used, and so on On the contrary, it will increase the construction difficulty for the follow-up reconstruction, resulting in the corresponding economic and human resources loss.
