Exploring Management Risks of Compressed Air in"Technical Specification for Cleaning and Disinfection of Flexible Endoscopes"
SU jiancheng
Abstract：Flexible endoscopes are generally dried using compressed air after cleaning and disinfection.To ensure that the clean state after the final rinse is not compromised,the compressed air used must meet the clean quality standards.Moisture,particulate matter and microorganisms are the main contaminants in clean compressed air.At present,medical institutions generally lack the awareness regarding management and control of such risks,primarily due to the absence of explicit control requirements in existing regulatory documents.Based on the principles of risk management,it is imperative to refine the corresponding technical requirements.To effectively ensure that the microbial limits of endoscopes meet standards after cleaning and disinfection,it is recommended to implement the same microbial control measures for compressed air that are as stringent as those for cleaning water.To address the technical gaps in the WS 507-2016 specification,it is advisable to reference the relevant technical requirements for clean compressed air outlined in the Good Manufacturing Practice(GMP)documentation for supplementation and refinement.
