【摘要】：目的探讨脉动真空蒸汽灭菌湿包的成因,寻找改善湿包的方法,以减少湿包率。方法采用不同的承载方式、不同的包装材料将器械、器具进行打包,灭菌前称重,装载上、中、下3层灭菌架,脉动真空灭菌器灭菌,灭菌后冷却,结合目测法和称重法共同判断湿包率。结果通过称重法判定为湿包的现象仅带棉布的包装材料存在,目测观察判定湿包的为使用双层无纺布、一层SMMMS无纺布和一层湿法无纺布,其比使用棉布为包装材料的数量多;包裹重量为2 600~2 900g的湿包率最高为28.3%;双层SMMMS无纺布采用方盘作为器械承载托盘的方式湿包率最高,为88.9%,而采用篮筐+吸水纸的承载方式产生的湿包率最低,为20.0%,湿包与灭菌时的装载可能有一定的关系,置于底层(排气口)最容易产生湿包,中间层次之,顶层最不容易湿包。结论更换无纺布可能并不是造成湿包的成因,它可能只是使湿包问题暴露出来;使用篮筐加吸水纸的承载方式可以更好地改善湿包。
[Abstract]:Objective to explore the causes of pulsating vacuum steam sterilization wet package and to find ways to improve the wet package to reduce the wet package rate. Methods different loading methods and packaging materials were used to package the instruments and instruments, weighing them before sterilization, loading the upper, middle and lower layers of sterilizers, sterilizing pulsating vacuum sterilizers and cooling them after sterilization. The wet package rate is judged by visual method and weighing method. Results only the packaging material with cotton cloth was found by weighing method, and the number of wet wrap was more than that of cotton cloth, which was determined by visual observation as using double-layer non-woven cloth, a layer of SMMMS non-woven cloth and a layer of wet non-woven cloth. The wet package rate of the packing weight is 2 600 ~ 2 900g, the highest is 28. 3%, and the wet package rate of double layer SMMMS non-woven cloth is the highest, 88. 9% by using the square disk as the instrument carrying tray, while the wet package rate is the lowest by using the hoop water absorbent paper. There may be some relationship between the wet bag and the sterilizing loading. It is most easy to produce the wet bag at the bottom layer (exhaust port), the middle level and the top layer the least easily wet bag. Conclusion the change of non-woven cloth may not be the cause of wet bag, it may only expose the problem of wet bag, and the load way of using basket and water absorbent paper can improve the wet bag better.
