图3是根据本发明的一个实施方案的等离子体灭菌设备的结构图。图中的等离子体灭菌设备包括两个灭菌舱1a和1b,而真空装置(真空泵)2、灭菌剂(H2O2)注入装置3、等离子体发生装置(等离子电源)4则各有一个。
灭菌舱1a和1b分别设有用于并行连接到真空装置2的真空抽气口504a和504b;用于并行连接到灭菌剂(H2O2)注入装置3的H2O2注入口601a和601b;用于并行连接到等离子体发生装置4的电极馈入702a和702b。
灭菌舱1a和1b分别包括灭菌舱门12a和12b;在舱门上和舱体外设有多个加热片9a和9b。此外,灭菌舱1a和1b上还分别装有真空计8a和8b。

按照以上的方法,使用一套配套装置(真空装置、灭菌剂注入装置、等离子体发生装置)可以实现对两个灭菌舱的灭菌操作。当配套装置对第一灭菌舱的作用完成后,处于空闲时,可以在不影响第一灭菌舱的灭菌操作的情况下,再被用于对第二灭菌舱作用。从而大大提高了配套设备的使用效率,同时还有利于减小灭菌操作时间,提高灭菌效率。特别是当需要对不同种类的待灭菌物品进行灭菌时,可以将待灭菌物品按照种类、对灭菌条件的要求等分类放入多个灭菌舱,并针对每个灭菌舱设置各自的参数,从而实现有效地灭菌处理,且能大大节约灭菌处理时间和设备成本。

图4是根据本发明的示例性实施方案的灭菌方法流程图。
首先是系统准备阶段4001,启动设备,系统预热,然后将待灭菌物品放入独立的灭菌舱1a或1b或两者内,并启动灭菌舱。之后,计算机控制单元判断真空泵是否空闲,并根据判断结果确定下一步操作:若是,则进入灭菌预备阶段4002,若否,则等待一分钟后,再次判断。
在灭菌预备阶段4002中:首先是步骤40021,启动真空泵、真空电磁阀,将所述灭菌舱抽真空至≤50Pa,之后关闭真空泵、真空电磁阀。该步骤用于干燥灭菌舱,除去多余水分。然后计算机控制单元判断等离子体电源是否空闲,并根据判断结果确定下一步操作:若是,则进入步骤40022,若否,则等待一分钟后,再次判断;在步骤40022,启动等离子体电源、继电器,并保持2分钟后,关闭等离子体电源、继电器。该步骤用于进一步干燥灭菌舱,并除去灭菌舱内可能残留的灭菌剂。随后进入步骤40023,打开真空进气阀,吸入过滤空气,使灭菌舱内保持常压≥1分钟后关闭真空进气阀。进入的过滤空气会扰动步骤40022中在灭菌舱内产生的气体和水分,以利于在下一步骤中将这些物质抽出灭菌舱。至此,灭菌预备阶段完成。灭菌预备阶段4002完成后,计算机控制单元判断真空泵是否空闲,并根据判断结果确定下一步操作:若是,则进入灭菌第一阶段4003,若否,则等待一分钟后,再次判断。
在灭菌第一阶段4003中:首先是步骤40031,启动真空泵、真空电磁阀,将所述灭菌舱抽真空至≤50Pa,之后关闭真空泵、真空电磁阀。接着是步骤40032,打开H2O2注入装置和H2O2电磁阀,将合适量的H2O2注入到灭菌舱内,将压力维持在800~1800 Pa,等待一足够时间之后关闭H2O2电磁阀。由于灭菌舱内处于真空状态,H2O2注入后,将迅速弥散开来,并附着在待灭菌物品表面上,弥漫时间约6分钟。在步骤40033,打开真空进气阀,吸入过滤空气,使灭菌舱内保持常压≥1分钟后关闭真空进气阀。吸入的空气扰动弥散雾化的H2O2,使其更充分地与待灭菌物品表面接触,特别是可以由此而进入到细长管状物品的管腔内,并附着到管腔内壁上,以达到更好的灭菌效果。至此,灭菌第一阶段完成。灭菌第一阶段4003完成后,计算机控制单元判断真空泵是否空闲,并根据判断结果确定下一步操作:若是,则进入灭菌第二阶段4004,若否,则等待一分钟后,再次判断。
在灭菌第二阶段4004中:首先是步骤40041,启动真空泵、真空电磁阀,将所述灭菌舱抽真空至≤50Pa,之后关闭真空泵、真空电磁阀。该步骤使得灭菌舱内达到等离子体激发条件。然后计算机控制单元判断等离子体电源是否空闲,并根据判断结果确定下一步操作:若是,则进入步骤40042,若否,则等待一分钟后,再次判断。在步骤40042,启动等离子体电源、继电器,并保持6分钟后,关闭等离子体电源、继电器。该步骤中,气化的H2O2在RF的作用下产生等离子体,通过低温等离子体的活性自由基作用,杀灭微生物。当RF波停止时,等离子体化状态结束,转变成稳定的氧分子及水分子。接着在步骤40043,打开真空进气阀,吸入过滤空气,使灭菌舱内保持常压≥1分钟后关闭真空进气阀。灭菌完成。

上述灭菌方法步骤仅为示例性的,可以根据需要、根据实际条件来设置具体的参数(例如真空度、时间等等)以完成不同的灭菌过程。根据灭菌舱内待灭菌物品种类,两个舱的灭菌条件可以设为相同,也可以不同。尽管常用的等离子体灭菌剂为过氧化氢,实际应用中,灭菌剂的种类、浓度、形式等也可以根据需要而变化。此外,灭菌过程中,配套单元的使用顺序、时间、次数等等也都可以根据需要进行调整。例如可以根据需要在不同灭菌阶段,以不同顺序、多次使用真空装置、灭菌剂注入装置、等离子体发生装置,以改进灭菌效果。
以上内容是结合具体的优选实施方案对本发明所作的进一步详细说明,应理解在不脱离本发明构思的前提下,还可以做出若干简单推演,都应当视为属于本发明的保护范围。
