目的研究启闭式灭菌盒,实现灭菌后预防二次污染。方法通过观察启闭情况和无菌检验,对自行设计改良的启闭式灭菌包装盒防污染效果进行评价。结果已改良的灭菌盒经连续1 000盒次灭菌试验,通气孔遮板移位发生率为1.4%;未改良灭菌盒移位发生率为12.6%。经对灭菌后下送过程中发生盒体分离和移位的灭菌盒内器械检测227件,全部有菌生长;未发生分离和移位的灭菌盒内器械检测227件,全部无菌生长。结论改良后的启闭式灭菌盒保障了包装盒的密闭性,形成了较有效的阻菌屏障,能避免灭菌后发生二次污染,达到了设计要求。
Objective To study the opening and closing sterilization box, to prevent secondary pollution after sterilization. Methods By observing the opening and closing conditions and sterility tests, the anti-contamination effect of self-designed improved open-closed sterilizing packaging was evaluated. Results The sterilized box that had been improved had a succession of 1 000 box sterilization tests, the incidence of ventilator screen shuffling was 1.4%, and that of unmodified sterilization box was 12.6%. After sterilizing, the process of sending and removing the cartridge occurred in the sterilized box, 227 pieces of equipment were detected in the box, all of which had the growth of bacteria. There were 227 instruments in the box without separation and displacement, all of which were sterile Grow. Conclusion The improved open-closed sterilizing box can ensure the airtightness of the packaging box and form a more effective antibacterial barrier, which can avoid secondary pollution after sterilizing and meet the design requirements.
