The positive treatment method of biological indicator of ethylene oxide sterilizer is as follows:
Stop the operation of the sterilizer, ensure that the door is closed, and then wait for the sterilizer to cool to a safe temperature.
Send the positive biological indicator to a professional laboratory for analysis to confirm whether there is bacterial or spore pollution.
for the contaminated articles, secondary sterilization is required. First, thoroughly clean and disinfect the contaminated articles, then put them back into new packaging bags and sterilize them with ethylene oxide. Sterilization conditions should be strengthened, such as prolonging sterilization time and increasing sterilization temperature.
articles that have been used and cannot be sterilized again should be destroyed to prevent the spread of bacteria or spores.
For the sterilizer that has been used, it is also necessary to thoroughly clean and disinfect, and replace the easily contaminated components such as filter element and germicidal lamp.
It should be noted that during the use of the ethylene oxide sterilizer, biological indicators should be used to verify each sterilization, and the parameters such as temperature, humidity and time during the sterilization process should be carefully recorded. If positive treatment is found, measures should be taken in time to deal with it, and the sterilizer and operation process should be inspected and improved to ensure sterilization effect and safe operation.
