目的探讨管腔型灭菌过程挑战装置在压力蒸汽灭菌批量监测中的应用。方法采用化学指示剂管腔型灭菌过程挑战装置对脉动真空压力蒸汽灭菌器灭菌包批量监测。结果经过30锅次的灭菌过程验证,此管腔型化学PCD对脉动真空压力蒸汽灭菌批量监测结果与同锅次灭菌物品包内的生物监测结果一致,达标率均为100%。结论管腔型化学PCD灭菌过程挑战装置可以作为压力蒸汽灭菌批量监测手段,通过PCD灭菌后指示条的颜色变化,可以直接了解该批次灭菌物品包内的灭菌效果,观察灭菌效果很方便,快速决定灭菌物品放行。
Objective To investigate the application of the challenge device of the lumen-type sterilization process in the batch monitoring of pressure steam sterilization. Methods A batch reactor was used to monitor the sterilization package of pulsating vacuum pressure steam sterilizer by using the chemical indicator lumen-type sterilization process challenge device. Results After 30 pots of sterilization process verification, this lumen-type chemical PCD batch pulsating vacuum pressure steam sterilization batch monitoring results and the same pot sterilization package biological monitoring results, the compliance rate was 100%. Conclusions The challenge device of lumen-type chemical PCD sterilization process can be used as a batch monitoring method of pressure steam sterilization. By means of the color change of the indicator strip after sterilization by PCD, the sterilizing effect inside the batch sterilization package can be directly understood, Bacteria effect is very convenient, rapid decision sterilization items release.
