ABSTRACT
OBJECTIVE To compare the monitoring effect of 2 kinds of B-D testing package.METHODS 2 kinds of testing package around the air vent of first pot sterilizer before antiseptic every day were used preheating 5 min.Start to move the B-D procedure when the band pressure to achieve above 100 kPa with 3 time of pulsation vacuum,inner chamber pressure of 210 kPa,the temperature of 134 ℃ and time of 3.5 min.RESULTS Except the false negative caused by package factor,the testing accurate rate of disposable B-D testing package was 100%.But the testing accurate rate of repeated uses B-D testing package was 90%.CONCLUSIONS The disposable B-D test package may respond promptly the breakdown of sterilizer and avoid the false negative result which the artificial pack factor creates.The test result is accurate.The disposable B-D testing package for examination of autoclave exhaust cold air degree is obviously better than the self-made cotton fabric testing package.
ABSTRACT
OBJECTIVE To analyze the monitoring performance and testing efficacy and reliability of standardized disposable B-D test pack and standard linen test pack,and summarize the corrective actions based on failure analyses for future reference.METHODS The two different test packs were employed to evaluate the vacuum performance of dynamic air removal sterilizer.RESULTS We enrolled 400 standardized disposable B-D test packs and standard linen test packs respectively.The disposable pack failed 4 cases with the success ratio 99%,while the linen pack failed 30 cases with the success ratio 92.5%.CONCLUSIONS The poor conformity of hand-made linen test pack,variation of steam pressure,sterilizer failure,and unprofessionalism of sterilizer operator contribute as main failure causes in B-D test.Standardized disposable B-D test pack can decrease subjective factors significantly,and the test results are more reliable and standardized.
ABSTRACT
This paper analyzes the disqualification factors influencing B-D test results by using B-D test monitoring. Effective methods were taken to remove them and the problems were found in time for overhauling the sterilizer. The forevacuum steam sterilizer should be kept in good state and regulated strictly so that it can work in program with qualified sterilizing quality,thus ensuing a safe and reliable clinical application.
ABSTRACT
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.
