灭菌装载方式对纸塑包装器材湿包的影响分析

Impact of sterilization loading method on wet paper-plastic packages of equipments

目的分析纸塑包装器材灭菌摆放不当容易产生湿包的现象,寻求避免纸塑包装器材产生灭菌湿包的有效措施,确保该类器材灭菌的效果。方法将正常使用的部分器械或器材分成小器械独立包装组、应急备用器械包装组和管腔器械包装组,然后用纸塑包装袋进行热合密封包装,数量分别为2 420包次、316包次和456包次,再将3组纸塑器材包分别采用纸面向上、塑面向上、纸对纸和纸对塑的方法进行灭菌摆放试验,最后待灭菌卸载后取出器材包观测湿包产生情况。结果小器械独立包装组纸面向上、塑面向上、纸对纸和纸对塑摆放并灭菌后的湿包发生率分别为3.93%、4.64%、0.43%和0.32%,应急备用器械包装组的湿包发生率分别为14.29%、19.05%、1.72%和0.86%,管腔器械包装组的湿包发生率分别为16.67%、14.58%、1.11%和0.56%。结论纸塑包装器材灭菌湿包的发生,受灭菌摆放方式和包内金属器械体积的影响较大;,侧向灭菌摆放能较可靠防止湿包产生,建议在日常灭菌装载工作中尽可能侧放,并保证纸面不受过多遮挡,促进灭菌所产生冷凝水的排出。

OBJECTIVE To analyze the causes of wet paper-plastic packages of equipments due to inappropriate placement of wet paper-plastic packages of equipments and seek effective measures for prevention of wet paperplastic packages so as to ensure the effect of sterilization of the equipments.METHODS The normally used equipments or devices were divided into the small device independent packaging group,the emergency equipment packaging group,and the vascular device packaging group,then the paper-plastic packages were treated with heat bonding sealed packaging,the quantities were 2 420 times,316times,and 456 times.The three groups of paper-plastic packages were sterilized by being respectively placed upward in paper,upward in plastic side,paper facing to paper,and paper facing to the plastic side;the status of the wet paper-plastic packages was observed after the unloading of the sterilization.RESULTS The incidence of wet packages was 3.93% by being placed upward in paper in the small device independent packaging group,14.29%in the emergency equipment packaging group,16.67%in the vascular device packaging group.The incidence of wet packages was 4.64% by being placed upward in the plastic side in the small device independent packaging group,19.05% in the emergency equipment packaging group,14.58%in the vascular device packaging group;the incidence of wet packages was 0.43% by being placed paper facing to paper in the small device independent packaging group,1.72%in the emergency equipment packaging group,1.11%in the vascular device packaging group;the incidence of wet packages was 0.32% by being placed paper facing to the plastic side in the small device independent packaging group,0.86%in the emergency equipment packaging group,0.56%in the vascular device packaging group.CONCLUSIONThe placement approach volume of packed mental equipments are the major cases of the wet packages.The lateral placement can effectively prevent the wet packages,and it is suggested that the packages should be placed laterally during the routine sterilization loading,keep the paper side exposed,and promote the discharge of condensed water generated by sterilization.
