Abstract: According to the national soft endoscope cleaning standard and the difference between the previous and latest version, the origin decontamination equipment is upgraded. Sensory control monitoring results in the last year shows that the average cleaning time for a single endoscope has been reduced from 20 min 55 s to 17 min 16 s. The number of bacterial colony has been reduced from 6.8 to 3.1. The pass rate of sensory control monitoring keeps steady. The upgraded decontamination equipment not only meets the requirements of the latest version of the standard,but also improves the efficiency and effectiveness of electronic endoscope disinfection.
