Abstract: Objective To discuss the optimal placement of instruments in ultrasonic cleaner with Octave software and aluminum foil corrosion method in central sterile supply department (CSSD). Methods The aluminum foil with length and width of 15cm and thickness of 15μm was vertically put into the ultrasonic cleaner with frequency of 37 kHz. After running the cleaner for 90s, the aluminum foil was taken out and dried. The next experiment was conducted after the aluminum foil was replaced, and the experiment was repeated 30 times. The corroded aluminum foil was cut to 8 cm×8.5 cm and then the image was collected. Octave software was used for image analysis. The image was divided into four regions of A, B, C and D from top to bottom. The corrosion area of aluminum foil in region A, B, C and D was compared and the wavelength(λ) was calculated by the corrosion distribution in each area. Results The corrosion area of aluminum foil in region A, B, C and D was different (P<0.05). Further pair-up comparison showed that there was no significant difference between region A and B and between C and D (P>0.05). The corrosion area of aluminum foil in region A and B was smaller than that in C and D, and the difference was statistically significant (P<0.05). When the frequency was 37 kHz, the ultrasonic wave wavelength was 4.26 cm. Conclusion The intensity of cavitation effect under the liquid level is positively correlated with the depth during ultrasonic cleaning in the CSSD. It is recommended that the instrument should be placed at a lower position in the cleaning basket as far as possible. Meanwhile, based on the characteristics of ultrasonic transmission in water and the frequency of ultrasonic cleaning machine commonly used in the CSSD, the position of the instrument should be no higher than 0.5cm below the liquid level.
