超净工作台说明书先容(2)

    Clean Bench at the back or front air inlet below the metal mesh cover within a normal foam piece or non-woven fabrics used to block large particles of dust, should be a routine check, unpick and wash, such as found in foam aging, must be promptly replaced. In addition to outside air inlet, where gas leakage pores, it should be blocked strict, such as patching, plug of cotton and paste glue paper. Table inside the front cover of the metal mesh filter is super, super filter may be replaced, as a result of the use of long years, dust jam, wind speed decreased, can not guarantee aseptic operation, can be replaced with new.     
    Clean Bench length of life related to the degree of air cleanliness. Clean Bench in temperate regions may be in the general laboratory use, but in tropical orsubtropical regions, because the atmosphere contains high levels of pollen, dust or more areas, Clean Bench are advised to put a better interior double doors. Any case, Taiwan should not be ultra-clean air inlet hood facing the open door or window, so as not to affect the filter life.    
    Sterile room should be on a regular basis with 70% alcohol or 0.5% phenol spray dust and disinfected with 2% wiped countertops and appliances Bromogeramine (70% alcohol can also be), with formalin (40% formaldehyde) plus a small amount of high manganese airtight fumigation potassium on a regular basis to meet the ultraviolet sterilization lamps (each to open more than 15 minutes) and so on means of 
disinfection and sterilization, sterile rooms in order to maintain regular high level of sterility. Vaccination should also be equipped with a UV box inside lights, turn on the lights more than 15 minutes prior to use radiation sterilization, but not of the Department any exposure there is still bacteria. UV light to open longer, it can stimulate oxygen molecules in the air to enter the ozone molecule synthesis, this gas composition has a strong bactericidal effect, you can not directly shine on the corner of ultraviolet sterilizing effect produced. Because ozone unhealthy, on entering the operation should be preceded by turn off the UV lamp off after more than 10 minutes you can enter.    
     In the ultra-clean the table can also be hoisting UV ultraviolet light, but it should be packed in light shade outside, and stagger the lights arranged in parallel, so that at work, without prejudice to lighting. Ruoqiang ultraviolet light into light shade (glass) inside, which is useless, since ultraviolet light can not penetrate the glass, it is a quartz glass tube, rather than made of silicate glass. 
使用方法  
超净工作台内的小环境可被紫外灯消毒,并由高效过滤器鼓风系统使台内形成一个较稳定的无菌环境。工作中人的活动要尽量少改变台内的空气循环系统。 主体内容: 
1. 目的 规范净化工作台操作与维护工作,确保仪器正常运作。 
2. 适用范围:本实验方法适用于微生物检验中净化工作台操作与维护管理。 3. 检验人员职责:负责此仪器操作和维护管理 4. 操作及维护规程 4.1操作规程 
4.1.1使用工作台时,应提前30分钟开机,同时开启紫外杀菌灯,处理操作区内表面积累的微生物,30分钟后关闭杀菌灯(此时日光灯即开启),启动风机。 4.1.2对新安装的或长期未使用的工作台,使用前必需对工作台和周围环镜先用超静真空吸尘器或用不产生纤维的工具进行清洁工作,再采用药物灭菌法或紫外线灭菌法进行灭菌处理。 
4.1.3 操作区内不允许存放不必要的物品,保持工作区的洁净气流流型不受干扰。 
4.1.4 操作区内尽量避免作用明显扰乱气流流型的动作。4.1.5 操作区的使用温度不可以超过60℃。 4.2 维护规程及维护方法 
4.2.1 根据环境的洁净程度,可定期(一般2~3个月)将粗滤布(涤纶无纺布)拆下清洗或给予更换。 
4.2.2 定期(一般为一周)对环境周围进行灭菌工作,同时经常用纱布沾酒精或丙酮等有机溶剂将紫外线杀菌灯表面擦干净,保持表面清洁,否则会影响杀菌效果。 
4.2.3 当加大风机电压已不能使风速达到0.32m/s时**更换高效空气过滤器。 4.2.4 更换过滤器时,可打开顶盖,更换时应注意过滤器上的箭头标志,箭头指向即为层流气流向。 
4.2.5 更换高效过滤器后,应用Y09-4型尘埃粒子计数器四周边框密封是否良好,调节风机电压,使操作区平均风速保持在0.32-0.48m/s范围内,再用Y09-4型尘埃粒子计数器检查洁净度 
使用管理 
1 目的: 维持屏障系统的生物洁净度,保护工作人员的安全,保障机组的正常运转,尽量减少可影响科研成果的各种可变因素。 
2 原则: 屏障系统内的超净工作台只能用于建立动物模型的手术、转基因小鼠的日常操作。 3 使用管理: 
(1)每次使用超净工作台时,实验人员应先开启超净工作台上的紫外灯,紫外照射30分钟后使用。 
(2)开启超净工作台工作电源,关闭紫外灯,并用75%的酒精或0.5%过氧乙酸喷洒擦拭消毒工作台面。 
(3)整个实验过程过程中,实验人员应按照无菌操作规程操作。 
(4)实验结束后,用消毒液擦拭工作台面,关闭工作电源,重新开启紫外灯照射15分钟。 (5)如遇机组发生故障,应马上通知实验动物室,由专业人员检修合格后继续使用。 (6)实验人员应注意保持室内整洁。
