目的了解影响B-D试验的因素,提高试验的准确性,用于评价和了解预真空压力灭菌器冷空气排出效果和饱和蒸汽穿透的效果。方法每日灭菌前采用实际测试方法进行观察。结果连续3年进行了913次B-D试验,失败26次,合格率为97%。不合格的试验中,11次为供汽、供水问题,8次为设备本身问题,7次为操作不当。结论 B-D试验受诸多因素影响,在操作过程中一定要高度重视,操作前一定要进行严格检查。
Objective To understand the factors influencing B-D test and to improve the accuracy of the test, to evaluate and understand the effect of pre-vacuum pressure sterilizer cold air discharge and saturated steam penetration. Methods Daily sterilization before the actual test method for observation. The results of 913 consecutive 3-year B-D test, failed 26 times, the passing rate of 97%. Unqualified test, 11 times for the steam supply, water supply problems, 8 times for the equipment itself, 7 times for improper operation. Conclusion B-D test by many factors, the operation must pay great attention to the operation must be carried out before the strict inspection.
