Objective To explore the application effects of different types of multi enzyme cleaning solutions in the cleaning of various medical devices in disinfection supply centers (CSSD). Methods 1200 reusable medical devices collected by CSSD in hospitals from June 2024 to March 2025 were selected and divided into four groups based on cleaning methods and device types: Group A (manual cleaning+manual specialized powerful multi enzyme cleaning solution), Group B (mechanical cleaning+enzyme based cleaning solution), Group C (ultrasonic cleaning+full effect multi enzyme cleaning solution), and Group D (traditional cleaning solution control group). Evaluate the cleaning effect using visual inspection, magnifying glass examination, ATP bioluminescence method, and protein residue detection method, and record the incidence of instrument corrosion and functional maintenance rate. Results The comprehensive cleaning qualification rate of groups A, B, and C was higher than that of group D, the incidence of instrument corrosion/aging was lower than that of group D, and the functional maintenance rate was higher than that of group D (P<0.05). Conclusion Multi enzyme cleaning solution can efficiently decompose organic pollutants through the synergistic action of composite enzymes. Different types of products are suitable for different cleaning scenarios, which can significantly improve the quality of instrument cleaning and reduce corrosion risks. It is worth promoting in CSSD.
