Abstract:: Abstract: Objective?To evaluate the effectiveness of medical vacuum ultrasonic cleaners for cleaning loaner instrument. Methods A set of total knee replacement tools was randomly divided into a test group and a control group, with 104 pieces in each group. The pieces in test group were cleaned with a medical vacuum ultrasonic cleaner, and those in control group were cleaned with an ultrasonic cleaning+spray cleaning and disinfection machine. Visual inspection, residual protein test and ATP fluorescence assay were used to evaluate the cleaning effect, and the cleaning effects in two groups were compared. Results The visual inspection showed that the pass rate of instrument cleaning was 100% in both two groups. However, the residual protein test and ATP fluorescence assay revealed that the cleaning effect in test group was significantly better than that in control group, with statistical differences (P<0.05). Conclusion The use of medical vacuum ultrasonic cleaner can significantly improve the quality of loaner instrument cleaning.
