Optimization of mechanical cleaning scheme for glass cupping device based on orthogonal test
Objective To study the optimum scheme of mechanical cleaning for glass cupping device based on orthogonal experimental design.Methods The 4 factor 3 level orthogonal test method was used to divide and 12 glass cupping devices were divided into one group.Different initial washing time,enzyme washing process temperature,rinsing time,drying time and temperature in the automatic cleaning and disinfection machine were used to clean and disinfect the glass cupping device.ATP biofluorescence method was used to detect the cleaning and disinfection effect of glass cupping device.Based on the above results,the best cleaning scheme was screened.Results Among the candidate influencing factors in orthogonal test,the order of significant influence on the cleaning and disinfection effect was initial washing time>enzyme washing temperature>rinsing time>drying temperature and time.The optimal cleaning scheme was the initial washing time for 3 min,the optimal water temperature of enzyme washing for 60℃,the rinsing time for 1 min,and the drying temperature and time for 110℃/10 min.Conclusion The above automatic cleaning and disinfecting machine procedure can effectively improve the disinfection effect of glass cupping device and reduce the risk of hospital infection.
