B-D测试不合格原因分析及解决办法

Causes Analysis and Solutions to B-D test failure

B-D试验是检测脉动真空压力灭菌器是否达到灭菌要求的重要指标之一。因此,高压灭菌前,必须对脉动真空压力蒸汽(预真空)灭菌器进行B-D试验。通过分析B-D试验失败的原因,避免因技术因素所致的试验失败而造成的人力、物力、时间等资源的浪费,保证压力蒸汽灭菌效果的可靠性。

The B-D test is one of the important parameters for examining sterilizing effect of the pulsation vacuum pressure sterilizer, which has to be performed before application to sterilization. So before high pressure antisepsis, we must carry on the B-D test of the pulsation vacuum pressure steam sterilizer. With the causes analyzed, some solutions are put forward to enhance the reliability of B-D test failure.
