Failures of Chemical Indicative Cards Used in Pressure Steam Sterilizer and Countermeasures / 医疗卫生装备

ABSTRACT

Objective To explore problems of chemical indicative cards and adhesive tapes in the disinfection,and find out some measures for improving the sterilizing effect of the pressure steam sterilizer.Methods 100 stoves of time with various package,dressing and storage tank were disinfected by pulse pressure steam sterilizer and chemical indicative cards of 3M1250 pressure steam sterilizing package at the same pressure,time and temperature.All test wraps were examined and the real conditions were recorded after the sterilization.Results The discoloration of chemical indicative cards in 10 test wraps was not standard before the measures were taken.While after that,it didn't occur again.Conclusion The nonstandard discoloration of chemical indicative cards of 3M1250 pressure steam sterilizer is influenced by condensed water of steam during the steam sterilization.In order to make the chemical indicative cards change into standard black,the accurate using of chemical indicative cards,the standard stuff package and correct using of disinfector are required.
