Research on the Factors Damaging Hydrogen Peroxide Low-Temperature Plasma Sterile Packaging Bags and the Control of Link Quality
Objective:After discussing the factors damaging hydrogen peroxide low-temperature plasma sterile packaging bags(hereinafter referred to as Tyvek packaging bags),the damage rate of Tyvek packaging bags is lowered through the control of link quality,so as to guarantee the quality of sterile packing bags and the safety of patients.Methods:Design questionnaire and registration form By investigating 8606 instrument packaging bags sterilized by hydrogen peroxide low-temperature plasma from January 2019 to December 2019,the controllable factors damaging Tyvek packaging bags are analyzed from four aspects:instrument packaging sterilization,transfer and storage.By taking targeted interventions on 8155 instrument packaging bags sterilized from January 2020 to December 2020,the intervention effects of the key links and the damage rate are evaluated.Results:The main factors damaging Tyvek packaging bags mainly include improper transfer,storage and management of instrument packing bags,improper use of instrument boxes,improper loading and uploading operations of sterilization and wrong size of packaging bags.For these factors,related intervention measures shall be adopted to control the link quality,so as to lower the damage rate from 3.54％in the control group to 0.20％in the experimental group.The differences in damage rate are of statistical significance(P＜0.01).Conclusion:Tyvek packaging bags are influenced by controllable factors.Through reasonable link control and standard operations,the sterile packing bags can keep sterile from the end of sterilization to the usage by patients,which guarantees the safety of patients.
