Research on the Factors Damaging Hydrogen Peroxide Low-Temperature Plasma Sterile Packaging Bags and the Control of Link Quality

Abstract

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 packaging 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 the 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 packaging bags can be kept sterile from the end of sterilization to the usage by patients, which guarantees the safety of patients and is worthy of reference.
