ATP fluorescence detection for the cleaning effect of vacuum ultrasonic cleaner
Objective:To observe the cleaning effect of vacuum ultrasonic cleaner by adenosine triphosphate(ATP)fluorescence detection.Methods:According to random number table method,80 sets of laparoscopic instruments recycled from disinfection supply center of the hospital were divided into control group(manual+ultrasonic cleaning)and observation group(cleaning with vacuum ultrasonic cleaner),40 sets in each group.The cleaning effect in the two groups was compared by visual inspection of magnifying glass and ATP fluorescence detection.Results:The visual inspection method showed that difference in qualification rate of cleaning between the two groups was not statistically significant(P>0.05).Under ATP fluorescence detection,qualification rate of cleaning in observation group was higher than that in control group(97.50%vs 77.50%),total cleaning duration was shorter than that in control group,and total loss rate of instruments was lower than that in control group(1.00%vs 2.95%,P<0.05).Conclusion:Vacuum ultrasonic cleaner can improve cleaning effect in laparoscopic instruments,with easy application.
