Objective:To explore the application effect of electronic Bowie&Dick test technology and to provide a scientific basis for ensuring the accuracy,sensitivity,convenience and sterilization safety of Bowie&Dick test results of pulsation pre-vacuum steam sterilizer.Methods:From July and October of 2023,Bowie&Dick test were performed on pulsating pre-vacuum steam sterilizers No.6 and No.7 using an electronic Bowie&Dick tester and three disposable chemical Bowie&Dick test kits.The test results of different Bowie&Dick tests for the same sterilizer and the same Bowie&Dick test type on two sterilizers were analyzed,the test temperature data and usage efficiency of electronic Bowie&Dick test equipment were analyzed.Results:The unqualified rate of sterilizer No.6 in the electronic Bowie&Dick test was compared with the unqualified rate of chemical Bowie&Dick test 1,test 2 and test 3,and the difference was statistically significant(x2=16.68,22.20,0.27,P<0.05).There was no significant difference in the test results of chemical Bowie&Dick test 1 and test 3 between the two sterilizers(x2=0.55,0.00,P>0.05).The temperature difference between inside and outside of the two sterilizers electronic Bowie&Dick testers was compared,and the difference was statistically significant(t=45.44,P<0.05).The display time of electronic Bowie&Dick test results and the storage time of test data were shorter than those of chemical BD test,and the differences were statistically significant(t=-29.80,t=-37.12,P<0.05).The physical parameter monitoring records of the two sterilizers were all qualified.Conclusion:The sensitivity and convenience of electronic Bowie&Dick testing are better than those of traditional chemical Bowie&Dick testing,which can increase the safety and reliability of sterilization,improve work efficiency,improve the safety of traceability information storage and the convenience of searching,which is a new trend of Bowie&Dick testing.
