Preparation phase：
-
Check the equipmentEnsure that all components of the sterilization cabinet are intact, without damage or leakage. Check if the power and gas connections are normal.
Prepare itemsClean and dry the items to be sterilized, package them according to requirements, and ensure that the packaging materials are suitable for ethylene oxide sterilization.
Set parametersSet appropriate sterilization parameters based on the type and characteristics of sterilized items, including temperature, humidity, pressure, concentration of ethylene oxide, and duration of action.
Loading phase：
-
place itemsPut the packaged items into the sterilization cabinet, paying attention to leaving sufficient gaps between the items to ensure that the ethylene oxide gas can fully contact all surfaces of the items.
Close the cabinet doorEnsure that the cabinet door is well sealed and leak free.
sterilization stage：
preprocessingStart the sterilization cabinet, perform pre vacuum treatment, eliminate the air inside the cabinet, and create an environment suitable for sterilization.
-
humidifyAdd an appropriate amount of water vapor to the cabinet as needed, and adjust the humidity inside the cabinet to the set value.
Introduce ethylene oxideUnder the control of the control system, a predetermined concentration of ethylene oxide gas is introduced to start the sterilization cycle.
Monitoring processThroughout the sterilization process, closely monitor parameters such as temperature, humidity, pressure, and ethylene oxide concentration to ensure they remain within the set range.
Exhaust and Analysis Stage：
exhaustAfter sterilization, exhaust treatment is carried out to extract residual ethylene oxide gas and metabolites from the cabinet through a vacuum pump.
analysisIntroduce filtered clean air to restore normal pressure inside the cabinet, while further eliminating residual ethylene oxide gas in the items.
Unloading and Inspection Phase：
Take out the itemsOpen the cabinet door and take out the sterilized items.
Inspect itemsInspect the sterilized items to ensure that their packaging is intact and free from damage or contamination.
Recording and reportingRecord the relevant parameters and results of this sterilization process, generate a sterilization report for reference and traceability.
