Abstract: Objective　To evaluate the effect applying steam cleaning machine in cleaning medical instruments provided by other companies such as files. Methods　Eighty sets of medical instruments received by Jieyang People's Hospital from other companies from March to May 2021 were set as an observation group, and were cleaned by the steam cleaning machine. And eighty sets of medical devices instruments received by Jieyang People's Hospital from September to November 2020 were set as a control group, and were cleaned by ultrasound and high-pressure water gun before machine cleaning. After finishing the cleaning procedure, the cleaning effects of the two groups were evaluated by the visual method and protein residue test. The comparison between groups was performed by χ² test. Results　The qualified rates detected by the visual method and protein residue test in the observation group were significantly higher than those in the control group [100.00% (80/80) vs. 90% (72/80) and 96.25% (77/80) vs. 86.25% (69/80)], with statistical differences (χ²=8.421 and 5.010; P=0.004 and 0.025). Conclusion　The application of steam cleaning machine in cleaning medical instruments provided by other companies such as files can improve the cleaning effect, ensure the safety of medical instruments, and provide references for the improvement of the cleaning operation procedures of such instruments.
