摘要

Abstract

Objective

The present study intends to compare four aluminum foil placement modes in testing the cavitation effect of an ultrasonic cleaning machine so as to provide a reference for the operation in the central sterile supply department (CSSD).

Methods

The experiments were divided into Group A

Group B

Group C

and Group D according to the aluminum foil placement modes recommended by different national guides. Each group conducted 20 experiments before and after the failure of the simulated ultrasonic cleaning machine. The four groups' operation time

false positive rate

and fault detection ability were compared.

Results

The operation time was Group A

Group B

Group C

Group D. The false positive rate of Group C was higher than that of Group A and Group D (all

0.008). The fault detection ability of Group A and Group C was higher than that of Group B and Group D (all

0.008).

Conclusion

The aluminum foil placement mode of Group A

i.e.

one aluminum foil placed along the diagonal perpendicular to the bottom of the sink

has the shortest operation time and most reliable results

which is worth popularizing in CSSD.
