生物安全柜生物检测仪的原理和保养措施

来源：浙江孚夏医疗科技有限公司分类：工作原理 2023-04-20 09:29:09 8阅读次数

生物安全柜生物检测仪采用物理法对II级生物安全柜安全防护性能进行测试，具备人员保护，产品保护，交叉污染保护三种工作模式，主要用来确定气溶胶是否停留在安全柜内，外部的污染物是否进入到安全柜的工作区域以及安全柜中装置之间的气溶胶污染是否减到小。适用于医疗器械检测中心，疾控中心，计量检定部门和科研院所等部门对II级生物安全柜安全防护性能的检测。

工作原理：

用碘化钾模拟安全柜内所生成的污染气体或逃逸气体，用气溶胶发生器在生物安全柜内部或者外部特定位置输送碘化钾溶液，并产生雾状的碘化钾微小液滴，形成挑战气溶胶，利用向心力工作原理，使用空气采样器捕捉窗口逃逸的碘化钾气溶胶。采样结束后，取出采样器内的过滤薄膜，放到装有氯化钯溶液的培养皿中。过滤薄膜上的碘化钾液滴会展开，形成清晰可见的棕色小圆点。通过统计过滤薄膜上圆点的个数，来评价安全柜的防护能力。

维护保养：

1、如果安全柜内需要其他气体，应同时安装气体管道。

2、在搬运过程中，严禁将其横倒放置和拆卸，宜在搬入安装现场后拆开包装。

3、应安装于排风口附近，不应安装在气流激烈变化和人员走动多的地方，不应安装在门口。应处于空气气流方向的下游。

4、设备的背面、侧面离墙的距离宜保持不小于150㎜～300㎜的检修距离，顶部也应留有不小于300㎜的空间。

5、每次实验结束后应对工作室进行清洗和消毒。

6、预过滤器一旦受损，应及时更换。
